ABSTRACT
The 1997 Asian Financial Crisis raised serious questions about the nature of East Asia’s
rise to economic prosperity, once labelled as a ‘miracle’ by the World Bank. In particular,
East Asian governments were criticised for allowing rampant corruption to pervade their
economies. At a conceptual level, the overwhelming majority of studies argue that
corruption, defined as the misuse of public office for private gain, has impeded growth.
Empirically, many studies have shown the detrimental impact of corruption on economic
growth but few have analysed the particular effect of corruption on East Asia’s economic
growth in the years leading up to the 1997 Crisis, a period characterised by superior
economic growth rates against the backdrop of corruption. This study seeks to fill that gap.
By virtue of its clandestine nature, any study on corruption is subject to measurement
limitations and this study is no exception. The only available data on corruption are indices
published by a handful of various international organisations. Each of these indices follows
a similar format: they are based partly or wholly on surveys of the corporate sector in each
of the sample countries, the results of which are converted into corruption scores and used
to rank the sample countries. Although there is a general consistency in rankings across the
different indices, the survey questions tend to equate corruption with bribery. In one survey
which questioned respondents about corruption and bribery in separate questions, the
results indicated that the two are not necessarily synonymous at least in the minds of
respondents.
A brief analysis of the nature of corruption within East Asia reveals why the tendency to
equate corruption with bribery can be misleading, and therefore raises doubts about the
credibility of the aforementioned corruption indices. Many countries in East Asia are
shown to harbour a network of patron-client relationships within a centralised framework.
This led to strong rent-seeking behaviour from the corporate sector which became a key
component of the development oriented strategy adopted by the rulers of the day.
Government support for rent-seekers was consistently monitored and subject to
performance requirements. This aligned the interests of the corporate sector with those of
the government and ultimately led to strong economic growth. Countries such as South
Korea, Indonesia and Malaysia are good examples of this whilst a notable exception is the
iv
Philippines, where the system was heavily decentralised and rulers preferred personal profit
above social development and economic prosperity.
When using the available corruption indices as measures of corruption in a corruption-
growth model that is applied to cross-sectional data covering 141 countries in 1996,
corruption is found to have a significant positive relationship with economic growth for two
of the corruption indices. However, no particular significant relationship is found to exist
for East Asian countries within the sample. The corruption indices are then combined to
produce a single index of corruption which is then used in a corruption-growth model and
applied to panel data covering 33 countries over a twenty year period from 1984 to 2003.
This time the corruption variable is found to have a significant positive relationship with
economic growth for East Asian countries (excluding Singapore) during 1986-1996.
Finally, the concept of rent-seeking is examined as an alternative to the typical principal-
agent model of corruption used in the literature, based on its strong resonance with the
particular nature of corruption in East Asia. A measure of rent-seeking is developed, and
using cross-sectional data for 57 countries in 1996 reveals that rent-seeking has a
significant positive relationship with economic growth.

CHAPTER 1
INTRODUCTION
“East Asia has a remarkable record of high and sustained economic
growth. From 1965 to 1990 the twenty-three economies of East Asia
grew faster than all other regions...Most of this achievement is
attributable to seemingly miraculous growth in just eight
economies…Seemingly, the rapidly growing economies in East Asia
used many of the same policy instruments as other developing
economies, but with greater success. Understanding which policies
contributed to their rapid growth, and how is a major question for
research…”
- World Bank (1993, pp.v and 1).
The World Bank’s comments above highlight East Asia’s phenomenal growth rates prior to
1997, despite many institutions having deemed the region to be plagued with corruption.
The fundamental question this dissertation therefore seeks to answer is whether the impact
of corruption on East Asia’s economic growth prior to the 1997 Asian Financial Crisis may
in fact have been positive, thus challenging the general view that corruption impedes
growth. This introductory chapter presents a concise overview of the purpose of this
dissertation. It begins with a discussion about the relationship between corruption and
economic growth and identifies a section of the literature which finds that, contrary to
popular belief, corruption can enhance economic growth. The specific research objectives
of this study are presented in Section 1.2, followed by an outline of the dissertation.
1.1 Corruption and Economic Growth
One of the earliest studies to tackle the issue of corruption and economic growth was Leff
(1964), in which it was argued that corruption could in fact increase efficiency in an
economy. This occurs through the use of ‘speed money’, allowing entrepreneurs to avoid
bureaucratic delay by paying bribes. This theory was later reinforced by Huntington (1968).
Bribes also act as an incentive for bureaucrats to perform efficiently in the absence of
1
satisfactory pay structures (Rahman et al., 2000). Bardhan (1997) argues that if private
firms are bidding in bribes for a government contract then it follows that the highest bidder
must necessarily be the lowest-cost firm. Thus, awarding the contract to the firm offering
the highest bribe should maintain allocative efficiency (see Beck and Maher, 1986; Lien,
1986).
Backman (1996) acknowledges that a “candid appraisal of corruption would show that it is
not always nefarious to growing economies”. He argues that “corrupt practices in the public
decision making of developing economies could spur growth, particularly if they frustrate
inappropriate and anti-development government policies” (p.1). Further, “economies where
corruption is a way of life may arguably be more efficient than slightly corrupt economies
where…there are just a few players, making it less likely that the winner will be the bidder
who most values the tender” (p.1). Backman asserts that smuggling is an example of a
corrupt behaviour that “has almost always had a positive economic effect, as long as the
goods being smuggled are not of an illicit nature” (p.2). Backman explains that smuggling
circumvents trade barriers and “puts producers in direct contact with consumers and avoids
a government attempting to get in the way…[so that] the producers become wealthier, the
consumers happier, and pressure is put on domestic producers to be more competitive”
(p.2). In this way, general economic welfare is enhanced.
The overwhelming majority of the literature, however, argues that corruption slows down
the wheels of commerce and reduces efficiency, by institutionalising itself through its
chronic persistence. This ultimately impedes economic growth because by “forming
perverse patron-client relationships with the bureaucracy and state machinery and by
diverting resources and talent from productive purposes to corrupt practices, corrupt
investors hamper the overall prosperity of the nation by reducing economic growth by
adversely affecting the quality and quantity of investment” (Rahman et al., 2000, p.4).
The theoretical debate over the effect of corruption on an economy has produced many
empirical studies aimed at establishing a link between corruption and economic growth.
Using a growth accounting approach with economic growth regressed against an index of
corruption as the chief explanatory variable, it is generally found that corruption leads to
reduced domestic investment, reduced foreign direct investment and overblown
2
government expenditure. Corruption also distorts the composition of government
expenditure away from essential sectors towards less efficient but more manipulatable
public projects (Wei, 1999).
A seminal study in this field was Mauro (1995) (and his subsequent 1997 study) which
found that corruption leads to reduced economic growth. However, in his 1997 study
Mauro acknowledged that there were difficulties associated with the measurement of
corruption, and argued that the corruption indices that are used (based on surveys of the
corporate sector’s perception of corruption levels) are highly subjective and therefore not
entirely accurate. Perhaps more interestingly, the indices also fail to distinguish between
corruption at an elite level (such as government ministers receiving gifts from the ruling
regime) and corruption at a grassroots level (such as customs officials accepting bribes to
allow passage of illegal goods into the country). The latter is how corruption is typically
viewed in the literature and was conceptualised by Shleifer and Vishny (1993) in their
principal-agent model of corruption, where the government is seen as the principal and its
bureaucrats are agents who sometimes extort bribes at the expense of serving the
government’s interests.1 In fact this view of corruption is rather narrow and fails to capture
the ‘elite’ form of corruption, as Mauro (1997) described it. The result of this modelling
error is a failure to accurately measure the effect of corruption on economic growth in
regions where the so-called ‘elite’ form of corruption thrives, such as in East Asia. The
present study argues that this form of corruption can in fact be measured, and modelled,
when it is viewed as rent-seeking.
Mauro’s findings were supported by Rahman et al. (2000), amongst many others. However,
Li et al. (2000) argued that the effect is not as pronounced as in Mauro (1995). Intriguingly,
they claim that “during 1980-94 Asia did not pay the price paid elsewhere for corruption; in
other words, corruption may indeed have acted as grease money in Asia during this period”
(p.18). Rock and Bonnett (2004) attempted to analyse this inconsistency too. They
investigated the East Asian corruption-growth relationship from a political perspective, and
suggest that corruption impedes growth and investment in most developing countries but 1 Shleifer and Vishny (1993) also consider the issue of centralised corruption, where more than one good is sought after by the public and where more than one bureaucrat can offer those goods. They identify three possible scenarios based upon the behaviour of the different bureaucrats – collusion, independent supply, or competition. Centralisation in reference to East Asian corruption will be explored in Chapter 4.

increases growth in some East Asian economies. The East Asian experience is therefore of
considerable interest as explained in the next section.
1.2 Corruption Behind the East Asian Miracle?
Between 1986 and 1996, the average annual economic growth rate in East Asia was nearly
7 per cent, while in the rest of the world it was between 2 and 3 per cent, as shown in
Figure 1.1 (World Bank, 2005).2 Such high growth rates are common amongst many other
countries, but what made East Asia different was that it was able to sustain these rates over
such a long period. Further, income inequality in East Asia had also declined. Achieving
both those feats was unique and laudable (World Bank, 1993).

By definition a miracle is beyond explanation, however the World Bank, in its 1993 report,
identified the following factors as being responsible for East Asia’s growth:
• private domestic investment; 2 For the purpose of this study, East Asia refers to Singapore; Malaysia; South Korea; Thailand; Hong Kong SAR; Indonesia; the Philippines; and Taiwan. However, the World Bank’s 1993 report used Japan instead of the Philippines. In the empirical analysis, Taiwan is excluded due to unavailability of data.

• high savings rates that funded the investment;
• growth in manufactured exports based on absorption of technology;
• declining population growth rates which led to high consumption per capita;
• high productivity growth;
• increase in labor force skills; and,
• strong government intervention.
Interestingly, the International Monetary Fund (IMF) is of the view that the economic
success of East Asia seemed to confirm the convictions of two opposing schools of
economic thought. On the one hand, neoclassical liberalists called for governments to
ensure property rights, law and order, and adequately provide public goods without high tax
rates and price controls at a microeconomic level, and to ensure stable and low inflation, a
strong financial and banking system, open markets, and stable and realistic exchange rates
without excessive budget deficits. On the other hand, the revisionists believed that market
imperfections were bound to exist in the poorer countries, as production creates
externalities, credit is limited, and firms engage in unfair trade practices, and thus called for
an interventionist government to ensure that the economy developed through the
acquisition of technology and the allocation of funds for productive investment purposes.
The governments in East Asia had met all of these requirements and had done so with great
success (Sarel, 1996).
Many more factors were highlighted by other scholars and institutions, but all their analyses
shared one commonality – they were in praise of the economic success of East Asia. The
world was seeking to draw lessons from the East Asian miracle as it became a blueprint for
economic prosperity.
The World Bank’s 1993 report cited earlier was entitled ‘The East Asian Miracle:
Economic Growth and Public Policy’. Eight years later, the World Bank released another
publication entitled ‘Rethinking the East Asian Miracle’ (Stiglitz and Yusuf, 2001). The
reason for the rethinking was the 1997 Asian Financial Crisis. In July 1997, Thailand
devalued its currency in response to severe speculative attacks on the baht. What followed
over the next 18 months was a series of consecutive devaluations in the region (in response
5
to similar attacks). Even renowned economist Paul Krugman admitted that he was 90
percent wrong about East Asia, his only consolation being that everyone else was 150
percent wrong (Institute for International Monetary Affairs, 1999). The IMF (1998) pointed
to problems in East Asian banking systems, somewhat ironically given that it formerly
praised their governments for promoting the integrity of their banking systems (Sarel,
1996). Stanley Fischer (1998), then Deputy Director of the IMF, blamed crony capitalism
as a major cause of the crisis.
Fischer’s claim that ‘crony capitalism’ contributed to the downfall of East Asia is most
intriguing. For the ten years prior to 1997, East Asia was not only sporting high growth
rates, but high corruption rates as well. Figure 1.2 illustrates this fact. The dashed lines
represent the world average, and the corruption level is measured on a scale of zero to ten,
with ten indicating extreme corruption.3 With the exception of Singapore and Hong Kong,
the chart shows that the East Asian ‘miracle’ economies were all experiencing levels of
economic growth and corruption that were above the world average in 1995. This seems to
contradict the general view in the literature that corruption tends to impede economic
growth.
The particular relationship between corruption and economic growth in East Asia has been
largely overlooked in the literature. The present study investigates this relationship, and
seeks to determine whether corruption may have partly contributed to high growth in East
Asia during the years leading up to 1997, when the region was engulfed by a financial crisis
that led to a sharp decline in growth rates. Specifically, this study will:
• critically analyse the existing measures of corruption;
• develop alternative corruption indices;
• undertake both cross-sectional and panel data analysis;
• analyse the particular nature of corruption in East Asia; and,
• develop a technique for measuring rent-seeking, which will then be used as a proxy
for corruption.

1.3 Thesis Outline
This dissertation begins with an overview of existing literature followed by empirical
analysis. Though the relationship between corruption and growth represents the core theme
of the study, East Asia will feature prominently in the analysis as the region is of particular
interest. The remainder of this section describes the specific outline of the dissertation.
Chapter 2 provides a review of the literature that describes the concept of corruption. The
first half of the chapter focuses on the definition of corruption, and provides examples of
how corruption is typically defined in the literature. Following on from this, the chapter
then explains how corruption is modelled in an economy. The most popular model in this
regard is the principal-agent model of corruption pioneered by Shleifer and Vishny (1993).
This model is simple yet provides a model of corruption that is consistent with the way
corruption is defined in the literature. The second half of the chapter introduces rent-
seeking as an alternative model of corruption, and one that captures a very different
dimension of corruption that is largely overlooked in the literature.
7
Chapter 3 extends the literature review by providing a summary of the empirical studies
that analyse the effect of corruption on economic growth. A breakdown of these studies is
provided, showing each study’s theme, data and results. While there are many studies, this
chapter reveals two significant gaps in the literature. First, many of the studies that employ
regression techniques have not used panel data analysis. Second, hardly any studies analyse
East Asia exclusively. These are the gaps that the present study seeks to fill. A summary of
empirical studies involving rent-seeking is also presented and once more it is revealed that
few studies have analysed East Asia, and most studies suffer from an inability to produce a
reliable measure of rent-seeking. This provides the basis for the analysis in Chapter 8.
Chapter 4 provides a brief review of corruption in East Asia. Drawing on the handful of
studies that have applied the rent-seeking model of corruption to East Asia, the chapter
explains the nuances of corruption in East Asia through the analysis of patron-client
networks between the business sector and the government.
In Chapter 5, the issue of measuring corruption is examined. This issue is integral to any
study on corruption. A survey of corruption indices published by a handful of institutions
such as Transparency International and Political Risk Services Inc. is presented. Each index
is critically analysed, and compared with other indices to test their correlation and
determine whether the indices produce consistent country rankings. One particular index
(based on the 1997 World Development Report) reveals that corruption is not viewed
synonymously with bribe-paying, contrary to what the literature assumes. A selection of
these indices is chosen to represent corruption in the context of a cross-sectional regression
model.
Chapter 6 presents a cross-sectional model to be employed in the analysis of 141 countries
for the year 1996. Having covered the corruption data in the previous chapter, the economic
control variables to be used in the model are listed and explained. Regression results are
shown initially using the Kaufmann, Kraay and Zoido-Lobaton (KKZ) index as the
measure of corruption, followed by results using other indices (and pairs of indices). The
model is then adjusted to control for endogeneity problems. Dummy variables are also
included to test for the particular relationship between corruption and economic growth in
East Asia. Finally, the results are compared with those of similar existing studies.
8
Chapter 7 presents a corruption-growth analysis based on panel data. Some of the indices in
Chapter 5 are combined to form a composite index of corruption, and this is used in a
corruption-growth model covering 33 countries between 1984 and 2003. As per the
previous chapter, endogeneity is controlled for and dummy variables are included to
analyse the East Asian region. A sensitivity analysis is conducted using different forms of
the composite index (i.e., combined in different ways). The results are compared with those
of similar existing studies.
Chapter 8 then provides an analysis of results of the application of a corruption-growth
model using rent-seeking as an alternative measure of corruption. The rent-seeking model
considered is a modified version of that introduced by Katz and Rosenberg (1989). The
model is applied to a sample of 104 countries in 1996. Due to differing data sources the
sample is not the same as those used in earlier chapters. Finally, Chapter 9 provides a
summary of the dissertation’s findings and some concluding remarks.

“I cannot help but notice that ethnic Europeans have an infinite
capacity to convince themselves that whatever it is they may be
doing at the moment is right, is just, is proper…We accept
democracy, but not the liberal democracy of the West…Our
governments may not be the cleanest and the most incorruptible in
the world, but we do care for our people and our country enough to
work hard to develop and progress, to industrialise and build
prosperous economies…Remember that the Western ideologues
have been wrong so many times before.”
- Former Malaysian Prime Minister Dr Mahathir Mohamad.4
2.1 Introduction
Typically, corruption is viewed as something harmful. Dr Mahathir’s comments above
warn about the dangers of following ideologies simply because they are practised by the
powerful and the influential. Further, his comments suggest that corruption should not be
the single criterion by which governments should be judged. What matters, in Dr
Mahathir’s view, is the prosperity and progress of its society as it is this responsibility with
which governments are charged. Indeed, if one were to use the economic performance of
East Asia in the late 1980s/early 1990s to judge the governments of the region, one should
be showering them with praise for their miraculous achievement in that period. But what is
interesting is that those very same economies were also plagued with corruption in that
period, at least as far as Transparency International and other institutions were concerned.5
In order to investigate whether countries can achieve strong economic growth while
simultaneously being corrupt, one needs to understand the conceptual issues behind
corruption and its impact on economic growth. This chapter examines the extant literature
analysing corruption and its effects on economic growth. It begins by explaining how 4 This is an excerpt of the Malaysian Prime Minister’s speech at the final banquet of the Southern African International Dialogue at Swakopmund, Namibia on 29 July 1998 (Burling, 1998). 5 Other institutions providing measurements of corruption include the World Bank, the International Institute for Management Development, and Political Risk Services Inc..

corruption is defined in the literature, and outlines the theoretical issues associated with
corruption. The chapter then summarises the empirical literature studying both the direct
link between corruption and growth, and indirect effects via other determinants of growth.
2.2 The Concept of Corruption
Although literature on corruption and its impact on economic growth is quite rich, there is
hardly any agreement amongst the researchers about a definition of corruption (Sandholtz
and Koetzle, 2000; Lui, 1996; Jain, 2001; Bardhan 1997). It varies from study to study due
to the application of various measures to quantify corruption. It also depends on the type of
corruption. What follows is an exhibition of different views about the concept and types of
corruption based on the main studies in this area.
Shleifer and Vishny (1993, p.599) define corruption as the “sale by government officials of
government property for personal gain”. This refers to the collection of bribes in exchange
for providing permits or licences, or prohibiting the entry of competitors into the market.
While Wei and Wu (2001, p.3) accept this definition they prefer to think of corruption a
little more broadly “as a short-hand for ‘poor public governance,’ which can include not
only bureaucratic corruption, but also deviations from rule of law or excessive and arbitrary
government regulations”. Huang and Wei (2003, p.4) define corruption as “the erosion of a
government’s ability to collect revenue through formal tax channels [arising] through the
outright theft by tax officials, through hiding of taxable income by taxpayers, or through
practices whereby tax inspectors collaborate with taxpayers to reduce the latter’s tax
obligation in exchange for a bribe.”
Sandholtz and Koetzle (2000) point out that all definitions of corruption share three
common elements, namely:
• a distinction between the public and private sectors;
• an exchange of either a good or service by a government employee
(bureaucrat) in return for some inducement; and,
• an element of impropriety (as a result of a breach of either existing norms, or
the law).
11
These elements are brought together by Bardhan (1997) who defines corruption as “the use
of public office for private gains, where an official (the agent) entrusted with carrying out a
task by the public (the principal) engages in some sort of malfeasance for private
enrichment which is difficult to monitor for the principal” (p.1321). However, Bardhan
acknowledges that there are other kinds of corruption (e.g., that which involves only the
private sector, like paying a higher price to a scalper for a movie ticket, or using
connections to gain entry into a restricted venue, etc).6
Some studies, like Sandholtz and Koetzle (2000), refrain from defining corruption and
identify corruption by its characteristics. Lui (1996, p.26) assert that corruption is a rent-
seeking activity induced by an absence of a perfectly competitive market; that it is illegal;
and that it involves “some degree of power, which can be interpreted as a form of human
capital acquired through inheritance or investment”.7 Chakrabarti (2001, p.7) employs a
similar strategy, stating that “a corrupt activity must satisfy three criteria – it must have a
positive expected economic value to its perpetrators, it must have some risk of socio-legal
censure associated with it and it must adversely affect the economy”.
Jain (2001) takes a step further and identifies three types of corruption. The first type occurs
at an elite level, where the political rulers exploit their power to formulate policies that
serve their interests instead of the public interest. The second type is bureaucratic
corruption which is akin to Bardhan’s definition of corruption where bureaucrats extort
bribes in exchange for supplying a government good or service. A third type is legislative
corruption where the voting power of legislators can be heavily influenced under the guise
of ‘gift-giving’.
Bhagwati (2000, p.4) also makes a distinction between two types of corruption – rent-
creating and profit-sharing. Under rent-creating corruption cronies are rewarded by the
ruling power with monopolies in production or distributive activity; and under profit-
sharing corruption cronies are rewarded with a share in profit-making enterprises so that
“the cronies have an incentive to make the pie as big as they can”. Bhagwati concedes that
profits “siphoned off by cronies could well cut into tax revenues that build useful
6 See Argandona (2003). 7 The concept of rent-seeking will be explained later in the chapter.
12
infrastructure” and may be “reinvested productively by the cronies whereas tax revenues
may have been wasted”.
In spite of the various types of corruption, the most popular definition of corruption in the
literature is the misuse of public office for private gain. This definition of corruption refers
to the bureaucratic corruption that Bardhan (1997), Jain (2001) and others use in their
study. This will also be the definition used in the present study. However, Tullock (1996) is
of the view that this definition is by no means the most appropriate. He rightly identifies a
glaring problem with the definition of economic corruption as bribe paying: “People say
that corruption is taking action…for the secret reason of private benefit…However, as a
rough rule of thumb, most people who talk about corruption are thinking not about a
congressman who votes for crop restrictions because he thinks that will win elections but
about somebody who actually takes bribes” (p.11).
Tullock’s (1996) point highlights a problem in the corruption literature. As will be seen in
the empirical studies of corruption, a negative relationship between corruption and growth
is commonly found based on the popular definition of corruption as bribe-paying which
ignores the different types of corruption that exist in different countries. This myopic view
of corruption is also present in the theoretical issues surrounding corruption. These will be
discussed in the next section.
2.3 Economic Models of Corruption
Having defined corruption the next step is to introduce some economic models of
corruption. The most popular one in the literature is the principal-agent model of corruption
and this will be analysed first, before an alternative model is proposed.
2.3.1 A Principal-Agent Model of Corruption
At the theoretical level the effect of corruption on an economy is typically viewed from a
‘principal-agent’ perspective. Basically bureaucrats acting as agents for the government –
or the principal – have an opportunity to be corrupt and extract a private gain (bribe) for
themselves. Shleifer and Vishny (1993) developed this basic corruption model. The model
13
assumes that the bureaucrat exclusively possesses a particular government-produced good,
such as an import licence or the right to use a government road, valued at price P1. The
good is assumed to be homogeneous, and a demand curve, D, exists for this good from the
private sector (see Figures 2.1 and 2.2). The bureaucrat has the opportunity to restrict the
quantity of the good (which translates in practice to delaying the issue of an import licence
for example).

The model also assumes that the government does not monitor the bureaucrat’s actions, so
he can restrict supply without fear of detection from his superiors. Essentially the
bureaucrat is a monopolist and his sole aim is to maximise the bribes he can collect in
supplying the government good. The model also assumes that there is no cost involved for
the bureaucrat in producing the good since the government is paying the cost, though in
reality the bureaucrat may need to exert some personal effort.
To firstly determine the marginal cost to the bureaucrat, two situations need to be
distinguished. In the case without theft, the bureaucrat keeps the bribe that is paid (B) and
hands over the price of the good (P1) to the government. In this case, the marginal cost is
simply the price of the good, P1, and the bribe is the bureaucrat’s profit. The profit-
maximising quantity supplied is Q1, where marginal revenue equals marginal cost (P1).
14
This situation is illustrated in Figure 2.1. It is interesting to note that, in the case without
theft, the bribe resembles a commodity tax – in particular a revenue-maximising
commodity tax when marginal cost is equal to the price of the good, P1. In the situation
with theft the bureaucrat only charges the bribe, which he keeps for himself, and gives
nothing to the government. Thus he simply hides the actual sale from the government. If
the transaction is hidden then the bureaucrat does not incur a cost in providing the good,
therefore his marginal cost is zero. This situation is shown in Figure 2.2. Once again, the
profit-maximising quantity supplied is Q1, where marginal revenue equals marginal cost
(which is zero in this case). The price that the buyer pays equals the bribe to the bureaucrat,
which may in fact be lower than the actual price. In practice this may equate to a customs
officer allowing passage of contraband in exchange for a bribe which is lower than the
official duty (Shleifer and Vishny, 1993).
If the assumption that the bureaucrat’s corrupt practices cannot be detected by the
government is relaxed, the situation remains largely unchanged. The bureaucrat will simply
set the bribe at a level such that the benefits of corruption outweigh the costs of the penalty
imposed if the bureaucrat is caught. If the penalty is proportionate to the size of the bribe,
the bureaucrat may reduce the bribe and increase output. If the penalty is proportionate to
the number of people who pay the bribe (through a higher probability of someone
registering a complaint), the bureaucrat may raise the level of the bribe and restrict supply
(for further discussion, see Becker and Stigler, 1974; Rose-Ackerman, 1975; and Klitgaard,
1988).
Shleifer and Vishny (1993) also explain how corruption can spread quickly due to
competition. If bureaucrats receive jobs from their superiors by paying for them, clearly
those who extort the most bribes will be able to offer the highest bids. Amongst buyers,
competition will also see an increase in corruption. Those who pay bribes will lower their
costs and competition will force other buyers to follow suit or fall out of the market.
However, this will only occur in the case of corruption with theft. In the other case bribes
actually raise the buyers’ costs and there is an incentive for them to expose the corrupt
bureaucrats.
15
Ehrlich and Lui (1999) argue that bureaucratic corruption exists in all societies, during all
stages of economic development and under different political regimes. However, different
countries have different levels of corruption and liberal economists will blame the
regulatory state for its elaborate system of permits and licences. Bardhan (1997) claims that
this is an inadequate explanation, because countries like Mexico are perceived to be more
corrupt than South Korea and Taiwan despite the latter having higher levels of government
intervention. Another explanation is that different countries have different social norms as
shown in Andvig’s (1991) basic model in Figure 2.3.

B M Curve

On the diagram, the horizontal axis represents the number of corrupt bureaucrats, the end
point of which represents a situation where every bureaucrat is corrupt, and O marks the
origin where there are zero corrupt bureaucrats. The vertical axes measure the payoffs to
the bureaucrats. The M and N curves describe the marginal benefit for a corrupt and an
honest bureaucrat respectively. At the lower end of the horizontal axis, where there are few
corrupt bureaucrats, the benefit for the honest bureaucrat is higher than that of his corrupt
counterpart. However, as the number of corrupt bureaucrats increases, the benefit for the
honest bureaucrat declines (because he is being undercut by corrupt bureaucrats) and
eventually becomes negative when everybody is corrupt. The benefit for the corrupt
bureaucrat however increases, but only temporarily as competition in bribes forces the
16
benefit down. But the payoff for the corrupt bureaucrat is still positive when everybody is
corrupt (Bardhan, 1997).
The three equilibrium states are identified by A, B and C on Figure 2.3. A and C are stable
because either corruption is zero or rampant. At any point in between, the economy will
either move towards A (if there is low corruption) or C (if there is high corruption). Point B
represents an equilibrium where there is no difference between being corrupt or honest, but
it is unstable. This is because it requires only one extra bureaucrat (either honest or corrupt)
to enter the scene and sway the economy either towards A or C (Bardhan, 1997). This
model therefore explains why corruption may persist in some countries while it is never
allowed to develop in others.8
2.3.2 Rent-Seeking: An Alternative Model of Corruption
The term rent-seeking was first coined by Krueger (1974) although the concept was
originally introduced by Tullock (1967). As its name suggests, rent-seeking is defined as
the use of resources and effort in obtaining, maintaining or transferring rents (Khan,
2000a). In Krueger (1974) rent-seeking is shown to be competitive particularly in the case
where rents arise out of quantitative restrictions on trade. An import licence amounts to
such a quantitative restriction similar in effect to a tariff. Like Tullock (1967), Krueger
(1974) suggests that there would be resources invested in competing for that rent (import
licence) and uses the import licence on intermediate goods as an example. Such licences are
often allocated in proportion to the capacity of firms, so naturally the greater the investment
in increasing capacity the greater the expected receipt of import licences. Mitchell (1993)
argues that this will result in higher capital stock for firms, which will thus improve social
welfare.
Where government officials decide on how to allocate licences, firms can devote resources
to influencing the probability or expected size of allocations. According to Sobel and
Garrett (2002) this represents the distinction between direct and indirect rent-seeking.
Direct rent-seeking would involve monetary payments or ‘in-kind’ benefits such as free

17
meals and gifts that are given directly to a government official. Indirect rent-seeking refers
to advertising campaigns and other lobbying that is not directed at any individual
specifically. In their study, Sobel and Garrett (2002) looked at rent-seeking industries in the
US and found that significantly more enterprises were situated in state capital areas than in
noncapital areas, reflecting a considerable degree of rent-seeking.9
Negative Impact of Rent-seeking
Bhagwati (1982) claims that the rent-seeking behaviour identified by Krueger (1974) and
Tullock (1967) falls under what he terms directly unproductive, profit-seeking activities, or
DUP activities for short. These include any activities that “yield pecuniary returns but do
not produce goods or services that enter a utility function directly or indirectly via increased
production or availability to the economy of goods that enter a utility function” (Bhagwati,
1982, p.989). Three common examples of DUP activities are tariff-seeking lobbying, tariff
evasion, and premium seeking for given import licences. Bhagwati (1982) asserts that these
particular activities do not enhance or contribute to the productivity of an economy as they
arise out of a initially distorted situation and do not alleviate the distortion. Other DUP
activities however can create distortion from an undistorted initial situation, leave the initial
undistorted situation unchanged, and alleviate distortion from a distorted initial situation.
Pecorino (1992) finds that rent-seeking (a DUP activity) can contribute to growth through
acquisition of productive human capital. Murphy et al. (1993) distinguish between private
rent-seeking which deals with contests for existing stocks of wealth, and public rent-
seeking which refers to the government restricting licences and import quotas etc. The latter
is deemed to be more harmful to growth as it hampers innovation which in turn impedes
growth.
According to Baumol (1990) such harmful activities have existed in many areas of society
as far back as the 12th century where the legal system was used for rent-seeking purposes.
In one case, operators of two dams sued each other repeatedly for over a century until one
eventually ran the other out of business due to an inability to pay court fees. However in
some cases the rent-seeking ended up being productive where entrepreneurs competed for
grants of land and patents of monopoly from monarchs, albeit by chance since there was no
9 Rent-seeking can also occur within firms, signalling internal governance problems and firm inefficiency. See Vining (2003) for more details on this phenomenon.
18
tendency for the monarchs to use efficiency as a criterion for issuing such grants/patents.
Ultimately though, Baumol (1990) argues that the contribution to production depends on
whether resources are devoted to innovation or to rent-seeking and this in turn depends on
the relative payoffs of each alternative. Murphy et al. (1991) build on this point stating that
the allocation of talent towards rent-seeking can be damaging to an economy in the long
run. They find that countries with a higher proportion of engineering colleges grow faster
than those with a higher proportion of law concentrators, and lawyers represent an
allocation of talent towards rent-seeking.
Tullock (1993) takes Bhagwati’s argument one step further and highlights that rent-seeking
behaviour must not only be unproductive, but it must result in a loss to society as a whole
in order for it to be classified as rent-seeking. For example, a person who finds a cure for
cancer and then patents his finding in order to maximise his wealth is not an example of
rent-seeking, because the society still benefits from the cure. However, if the person then
obtained a law that prevented the import of a new and more effective cure of cancer
because he wanted to make profits from his own, older and less effective cure, then that
would be classified as rent-seeking since the public is prevented from receiving the benefit
of the newer cure. This illustrates that although rent-seeking behaviour may appear to result
in a complete welfare loss, it may in fact produce a positive outcome for society.
One of the most popular types of rents are monopoly rents. These exist when a single firm
has a monopoly over the production of a particular good, and is able to collect a rent equal
to the monopolist’s profit. Tullock (1993) uses the situation of a monopoly to illustrate
rent-seeking and demonstrate its social costs.10 In the case of a monopoly, rent-seeking
results in a welfare loss (Tullock, 1993). In Figure 2.4, Point C represents the cost of the
good, and P1 represents the price charged by the monopolist. The shaded area represents the
welfare loss to society when the monopolist extracts a rent because there is less quantity
supplied. However this is not deemed to be the only loss. Tullock (1993) argues that there
are further losses. Tullock claims that costs will actually increase when there is a shift from
competition to a monopoly. This is because the monopolist is no longer as willing to invest
the effort or resources needed to find the least costly way to produce the good in question,
10 See Posner (1975) for a detailed discussion of the social costs of a monopoly.
19
because the monopolist knows he can charge a higher price anyway. Palda (2000) expands
on this issue of high-cost producing firms. In the simple example of two firms competing
for a broadcast licence, if the firm with the higher transmission cost wins the rent then more
of society’s resources will be devoted to broadcasting.

Another loss lies in the monopolist’s efforts to maintain his monopoly. The monopolist
would have to invest resources in order to prevent other competitors from entering the
market. This investment in defence of monopoly powers can be classified as rent-seeking
behaviour.11 So Tullock (1993) argues that at least part, if not all, of the rectangle P1ABC
should also represent a welfare loss as it incorporates the resources invested in defending
the monopolist’s powers. The problem lies in identifying this loss in reality. As Sobel and
Garrett (2002) point out, the indirect expenditure is a major component of the overall rent-
seeking expenditure but by its very nature it is difficult to identify in practice – a problem
commonly referred to as the Tullock paradox (Tullock, 1998). This leads to the finding in
the literature that the observed social costs of rent-seeking will be much lower than what is
predicted in theory.
The net effect of the rent-seeking behaviour by a monopolist is the sum of the lost inputs
that are invested in rent-seeking and the social benefit or loss resulting from the actual rent 11 For an interesting comparison between rent-seeking models and conflict models, see Neary (1997).
20
itself. Khan (2000b) illustrates this net effect using Figure 2.5. The diagram assumes that a
particular economy can either produce cars or grain with its resources, and shows the
production possibility frontier PP for all possible combinations. The world price lines are
represented by the downward sloping straight lines. The efficient position for the economy
is the point A, where the world price is tangential to PP. Suppose that an import restriction
is imposed on cars (not shown on the diagram), raising the domestic price of cars. This will
result in a shift in domestic production from A to B. More cars will be produced locally at
the expense of grain, and society becomes worse off. As inputs are held constant, the value
of the lost output at world prices is the social loss. To compare the values at B and A, the
world price line is drawn through point B. Thus XY becomes the deadweight social loss,
which is the same loss identified by Tullock (1993) as the shaded area in Figure 2.4.

However, domestic car producers can begin lobbying politicians to maintain the import
restrictions, or impose further ones, and grain producers can be expected to lobby for
similar restrictions that would provide them with rents. This rent-seeking behaviour uses up
resources that could otherwise have been used to produce cars and grain. Therefore the loss
of inputs from production towards rent-seeking results in a shrinkage of the production
possibility frontier from PP to P’P’. Consequently the economy shifts from B to B’. To
measure the cost of this rent-seeking, a world price line is drawn through B’ and the
21
resultant difference between B and B’ is YZ. Therefore the net effect on society becomes
the sum of XY (deadweight social loss) and YZ (rent-seeking cost), yielding XZ (Khan,
2000b). One strand of the literature has considered the impact of deregulation of
monopolies in order to recover the deadweight social losses. However Poitras and Sutter
(1997) contend that the monopolist will invest resources to defend its position, while
reformers will expend effort in advocating deregulation, so that the result may see the gains
from deregulation being outweighed by its costs.12
What is the total value of the social cost? That depends on the measure of rent-seeking. It is
difficult to find an appropriate measure of rent-seeking. Cole and Chawdhry (2002) use the
number of registered interest groups in the US as a measure of rent-seeking. Del Rosal and
Fonseca (2001) analyse the Spanish coal mining industry and measure rent-seeking by the
magnitude of labour unrest. In other words, when workers go on strike, the costs to the firm
and the economy are a proxy for the total social cost. There are other ways of measuring
rent-seeking, and these will be covered in Chapter 8.
Positive Impact of Rent-seeking
Figure 2.5 illustrated the effect of a ‘value-reducing’ rent, i.e. a rent that has a negative
effect on society. But recall that there can also be rents that are beneficial to society. Khan
(2000b) uses Figure 2.6 to show the effect of a ‘value-enhancing’ rent. In Figure 2.6 the
import restrictions still result in increased domestic car production, from A to B, but B now
lies on a different production possibility frontier, P”P”. This can happen if the restriction
induces ‘learning’, i.e. the restriction is only for a limited time and subject to domestic car
producers learning to use technology to produce better cars.13 However, the cost of the
rent-seeking behaviour will see this new frontier fall short of P”P”, and end up as P’P’. In
spite of this, the net effect is XY less YZ, which gives XZ – a net social benefit. Bhagwati
and Srinivasan (1980) similarly show how rent-seeking can be welfare improving.
It is worth noting that although the government is in charge of imposing the import
restriction, it may only be doing this in response to lobbying from the private sector. This is
12 See Dewey (2000) for an in-depth discussion of rent-seeking and deregulation, and Drook-Gal, Epstein and Nitzan (2004) for an analysis of the mechanics of privatisation in the context of rent-seeking. 13 It is assumed that both grain and car producers will eventually benefit from learning.
22
a possible explanation as to why monopolies do not necessarily arise out of economies of
scale, but rather as a result of firms succeeding in finding preferential treatment from the
government which can use its powers to impede competition (Lambsdorff, 2002).

As Figure 2.6 shows, rent-seeking can be value enhancing when the rents are injected back
into the system productively and not simply wasted. This is known as the transfer of rents.
Rents based on transfers can include not only taxes and subsidies, but also transfers which
convert public property into private property. They are classified as rents because the
income is greater than any alternative of the recipients. However not all transfers are rents.
Pension payments and unemployment benefits are associated with a previous saving or
contribution similar to an insurance premium and are not classified as rents (Khan, 2000a).
Tullock (1993) argues that the most desirable outcome of rent-seeking is where the costs
are zero and the result is a transfer of wealth rather than its dissipation.
The effect of the transfer consists of two dimensions. On one side, the valuation of the
transfer by the ‘loser’ and the ‘gainer’ determines the welfare effect on society. Since a
poor person is likely to value a dollar greater than a rich person, then a transfer from the
23
poor to the rich would result in lower social welfare. The other dimension relates to the
effect on the incentives of the ones being taxed, which is usually negative.

Figure 2.7 shows that when a tax is imposed upon the ‘losers’, the marginal cost of
production is increased. This results in a lower quantity produced. The rectangle ABCD
represents the tax, or rent, which is then transferred to another sector. The triangle BCE is
the deadweight loss that represents the social cost of the fall in output. This situation is very
similar to the monopoly rent described earlier where rents were transferred from consumers
to firms, with the only difference being that there the transfer was organised through the
price mechanism, whereas here it is through the political mechanism (Khan, 2000a). Katz
and Rosenberg (2000) show that corporate taxes tend to favour rent-seeking by established
firms and discriminate against new and zero profit firms.
Rent-seeking and Corruption
Some types of rent-seeking behaviour can be viewed as a form of corruption. Indeed rent-
seeking incorporates a wide spectrum of activities, many of which are morally and legally
acceptable in some societies. The issue however is whether these practices would otherwise
be frowned upon outside these societies, and if so, whether they are (or ought to be)
captured in global corruption rankings. Later in Chapter 4, the nature of corruption in East
24
Asia will be analysed and it will be shown that the corrupt practices often occur under the
guise of rent-seeking behaviour. To explore the connection between the two phenomena,
consider Shleifer and Vishny’s (1993) model of corruption, which can be viewed from the
perspective of a private corporation (assume a monopolist) seeking a particular unique
licence. The corporation may engage in rent-seeking behaviour in order to ensure that it
receives the licence, and that the licence is not given to another corporation which may
threaten the original firm’s monopoly status. Figure 2.1 now becomes a representation of
the private firm’s situation, instead of the bureaucrat’s (in Shleifer and Vishny’s original
model). Once again, welfare losses arise. The first is due to the restricted quantity supplied
as a result of charging a high price (which is the monopolist’s rent). The second is due to
the higher input costs incurred because, as Tullock (1993) argued, the monopolist sacrifices
the resources required to keep input costs at a minimum in exchange for reaping higher
revenue (although this was irrelevant in the case of the corrupt bureaucrat). And the third
loss is due to rent-seeking behaviour, in trying to secure the licence from the bureaucrat.
This behaviour must be recognised as a welfare loss, because the monopolist is investing
resources purely and simply to extract a rent, and this investment does not yield any benefit
for society as a whole. Lambsdorff (2002) is of the view that the situation is no different to
a beggar who mutilates himself to exact more sympathy from passers-by and thus more
charity.
In fact, Lambsdorff (2002) argues that the rent-seeking model is a better way of analysing
corruption than the principal-agent approach. The principal-agent model assumes that the
principal (government) is not corrupt, rather it is the agent (bureaucrat) who bends or
breaks the rules devised by the principal to serve his own interests. Further, the model
assumes that the government also has complete control over the legal framework, and
consequent rewards and penalties. Lambsdorff feels that these assumptions are unrealistic,
especially in societies where the public sector is a corrupt entity. It is too simplistic to
assume that the government must be immune to corruption because it is in control of
legislation. Lambsdorff cites the case of Thailand, where people are prohibited from taking
(stealing) leaves or pebbles from certain areas. However, the Forestry Department was not
motivated by environmental protection incentives, rather it officially converted the areas in
question into tourist attractions or destroyed them for gas pipelines, purely for the benefit of
25
the department. To fully capture the effect of corruption and the welfare loss on society,
Lambsdorff (2002) believes the rent-seeking model is more appropriate.14
The nature of rent-seeking behaviour can determine whether it is perceived to be an act of
corruption. If the rent-seeking firm were to pay money to a politician, this would be
deemed as corruption. But if the same firm were to undertake extensive advertising, starting
political campaigns and engaging public relation agencies, this would not be seen as corrupt
behaviour (Lambsdorff, 2002). This illustrates the difference between direct and indirect
rent-seeking, as highlighted by Sobel and Garrett (2002). The government’s response to the
rent-seeking behaviour can also be perceived as being corrupt. In fact, this has become the
backbone behind the argument in favour of favouritism or ‘nepotism’ in government.
Pedersen (1997) shows how the government’s attempt to serve its own interests in the
context of rent-seeking has led to uneven distribution of benefits within developing
countries. Colombatto (2003) also provides an interesting characterisation of corruption
based on rent-seeking in different institutional contexts, i.e. developed countries,
totalitarian countries and transitional countries. Konstantin (2003) illustrates how unequal
countries like Russia are plagued by rent-seeking, as a result of government inefficiency.
Where corruption is a selling cost for the private supplier (rent-seeking), Fedeli and Forte
(2003) show that a centralised regime causes higher corruption. Mohtadi and Roe (2003)
finds that young and mature democracies achieve faster economic growth than countries in
mid stages of democratisation, producing a U effect, as a result of rent-seeking. Emerson
(2002) argues that in less developed countries, the high degree of corruption contributes to
industrial dualism – a large number of small, traditional firms and a handful of large,
modern firms. More corrupt countries tend to have fewer and larger modern firms, and
lower social welfare (and thus greater deadweight loss). Government rents are also higher.
Emerson (2002) finds a positive relationship between the degree of corruption in a country
and its percentage of large firms.

2.4 Conclusion
The most popular definition of corruption in the literature is the ‘misuse of public power to
provide private gain’. It is this definition which provides the basis for the principal-agent
model of corruption developed by Shleifer and Vishny (1993), which is how corruption is
typically modelled in studies examining its impact on an economy. However, corruption
can also occur in the form of rent-seeking. This process of private corporations establishing
patron-client networks with governments in order to secure rents is an alternative method of
modelling the effect of corruption on an economy. This study uses both frameworks in the
analysis of how corruption impacts upon growth, particularly in East Asia. The question
now is what have empirical investigations of this effect yielded? The next chapter seeks to
provide an answer to this question.

CHAPTER 3
LITERATURE REVIEW: EMPIRICAL STUDIES
Each country in Asia will chart its own way forward. Every country
wants to be developed and wealthy. They will adopt and adapt those
features or attributes of successful countries which they think will help
them succeed. If these features work and improve their rate of
progress, they will be permanently incorporated. If they do not work
or cause difficulties, they will be abandoned.
- Former Singaporean Prime Minister Lee Kuan Yew.15
3.1 Introduction
The comments of the former Singaporean Prime Minister echo the sentiments of Dr
Mahathir’s comments in the previous chapter. The architect of Singapore’s rise to
economic prosperity, Lee, makes it abundantly clear that Asian countries do not necessarily
need to follow the policies of other successful nations. Singapore clearly stands out
amongst its East Asian counterparts. Consistently appearing in the top ten in Transparency
International’s Corruption Perceptions Index, Singapore provides a perfect example of what
heights a country can reach in the absence of a bribe-seeking bureaucracy. But if other East
Asian countries can produce economic growth similar to that of Singapore’s in the presence
of corruption, then what conclusion does one reach? Is Singapore an anomaly? What is the
true impact of corruption on economic growth? This chapter provides a concise summary
of empirical studies concerning corruption and economic growth and presents a framework
for this study’s own analysis in later chapters.
3.2 Empirical Studies Analysing Corruption and Growth
The theoretical debate over the effect of corruption on investment, economic growth,
political stability and economic integration has led many scholars to conduct empirical
15 National University of Singapore, 2006.
28
research with the aim of establishing a link between corruption and these economic
variables. These authors mainly employed the growth accounting approach to examine the
impact of corruption on economic growth. An index of corruption (measured in various
ways as will be seen in Chapter 5) is used as the main explanatory variable. Literature in
this area is too vast and Table 3A.1 in the appendix to this chapter provides a summary of
the major studies in this area since 1995.
Wei (1999) provides a concise review of this material, which generally finds that corruption
leads to reduced domestic investment, reduced foreign direct investment, overblown
government expenditure, and distorted composition of government expenditure away from
essential sectors towards less efficient but more manipulatable public projects. Particularly
in the case of Asia, Wei concludes that there is no evidence to suggest that corruption in
that part of the world is anything but a hindrance to economic development. It is worth
noting that Wei begins the review with an anecdote about a Chinese restaurateur who
received a National Outstanding Private-Sector Worker Award and whose restaurant
consequently achieved such a high reputation that it was frequently patronised by
bureaucrats who never paid their bills, thus leading to the eventual closure of the business.
This is a somewhat surprising opening by Wei, having earlier dismissed anecdotal evidence
(that may suggest corruption is beneficial to growth) because “there is a limit to what
anecdotes can tell us” (p.3).
Wei’s anecdote is meant to demonstrate how corruption can kill a small business, but it
actually does a better job at explaining the difference between corruption in Asia, and
corruption in the rest of the world. One might argue that the bureaucrats who never paid
their bills were actually being repaid by the restaurateur for the award that was conferred
upon him, in recognition for the success of his business. The restaurant may truly have been
successful, and in any other culture the bureaucrats would probably have given the owner
an award anyway, but in Asia this is seen as a favour, and the restaurateur had to repay it.
Regardless, if the business was so successful on its own merits, one would expect that the
ongoing business from the restaurant’s other clientele would surely have compensated for
the lost revenue from the bureaucrats’ unpaid bills.
29
Most of the literature does indeed support Wei’s assertion that the link to economic growth
is deemed to be significant and negative, consistent with the ‘efficiency reducing’ view
discussed in Chapter 1 (Mauro, 1995 and 1997; Rahman et al., 2000). Poirson (1998)
argues that a reduction in corruption levels will only translate to an improvement in growth
in the long-term. However, Vehovar and Jager (2003) show that an improvement in growth
will not necessarily result in improvements in governance, particularly in the case of
Slovenia. Kaufmann (2003, p.1) argues that there has been “scant progress worldwide in
recent times in improving rule of law and governance, in controlling corruption, and in
improving institutional quality -- although there is clearly variance across countries”. Why
is it that countries do not strive to improve their institutions and root out corruption, and
remain caught in a circle of corruption and low economic growth? Mauro (2002) believes
one explanation lies in the absence of incentives for individuals to fight corruption when it
has become widespread. In fact, Chakrabarti (2001) claims that social corruption is derived
from individual corruption levels optimally chosen by agents with varying risk aversion
and human capital. Chakrabarti uses a multi-generational economy with heterogeneous
agents to show that there are locally stable equilibrium corruption levels with certain
socioeconomic determinants. In the worst case, corruption can become so rampant that it
stifles all economic activity.
Other studies have found corruption to have a positive impact on growth. For example,
Mendez and Sepulveda (2001) demonstrate that corruption enhances growth at low levels
of incidence, but reduces it at high levels. This implies the existence of some level of
corruption that maximises long-term growth.
Some studies have explored the effects of corruption on other variables that ultimately will
impact on economic growth. The literature in this area finds that corruption leads to
reduced investment. Expanding on his 1995 study, Mauro (1997) shows that a decline in a
country’s perceived level of corruption leads to an increase in its investment rate. Rahman
et al. (2000) also build on Mauro’s (1995) model and agree that corruption is significantly
and negatively associated with gross domestic investment, and can also drive away foreign
investment. In Africa, Gyimah-Brempong (2002) reveals that corruption leads to decreased
income per capita, indirectly caused by decreased investment.
30
According to Wei (1997), a rise in either the tax rate on multinational firms or the
corruption level in a host country reduces inward FDI. In particular, Wei concludes that
there is no support for the hypothesis that corruption has a smaller effect on FDI into East
Asian host countries. Wei (1997a) further states that the less predictable the level of
corruption, the greater its impact on foreign direct investment. In other words, corruption
resembles an unpredictable, random tax that adds to risk and uncertainty. An increase in
corruption is therefore no different to an increase in corporate tax. Interestingly,
Smarzynska and Wei (2000) suggest that not only does host country corruption reduce
inward FDI, but it also results in a shift towards joint ventures as opposed to wholly-owned
firms.
Vinod (2003) takes the analysis one step further, arguing that not only is corruption
negatively associated with investment, but that corrupt countries will place capital controls
to prevent capital flight to less corrupt countries, and uncovers a significant correlation
between corrupt countries and capital controls. On the issue of capital restrictions, Dreher
and Siemers (2004) assert that higher corruption induces stricter restrictions and vice versa.
Further, capital account restrictions induce higher corruption in the short-term but reduce
corruption in the long-term. Wei and Wu (2001) examine a possible linkage between the
composition of capital inflows and corruption, building on Wei (2000). The results suggest
that poor public governance is associated with a higher loan-to-FDI ratio (as well as a
country’s inability to borrow internationally in its own currency). This is said to be
associated with a higher incidence of a currency crisis, thereby suggesting that corruption
may increase the probability of a currency crisis.
The link between corruption and the composition of government expenditure is also worth
exploring because “most economists think that the level and type of spending undertaken
by governments do matter for economic performance” (Mauro, 1997, p.10). Mauro claims
that government spending on education as a ratio to GDP is negatively and significantly
correlated with corruption. Other components of government expenditure also exhibit a
similar connection with corruption, but only education remains significant when the level
of per capita income is used as an additional explanatory variable. As Mauro explains, this
control accommodates the relationship known as Wagner’s law – that government
expenditure as a percentage of GDP tends to rise as a country becomes richer. Mauro also
31
finds that government spending on defence or transportation displays no significant
relationship with corruption. There is also no evidence that corruption leads to excessive
expenditure on ‘white elephant’ projects. Fisman and Gatti (2002) produce evidence of a
strong negative relationship between fiscal decentralisation in government expenditure and
corruption. Bohn (2003) argues that political instability may lead to underinvestment in
infrastructure or anti-corruption measures. The main finding is that a political instability
threshold exists, below which a government will refuse to invest. Pellegrini and Gerlagh
(2004) reach a similar conclusion, asserting that corruption indirectly impedes growth
through political instability.
Tanzi and Davoodi (1997) challenge the notion that high levels of public expenditure
contribute to growth. They argue that corruption is likely to increase the number of projects
undertaken in a country, and enlarge their size and complexity. This results in an increase
in the share of public investment in GDP; a fall in the average productivity of that
investment; and a possible reduction in other essential areas of spending such as education
and health. Controlling for GDP per capita, Tanzi and Davoodi observe that high levels of
corruption are indeed associated with higher public investment, lower government
revenues, lower spending in essential areas, and lower quality of public infrastructure.
Generally, corruption encourages public investment while reducing its productivity. In a
similar vein, Del Monte and Papagni (2001) show that the efficiency of public expenditure
is lower in regions where corruption is higher, and that corruption has a negative effect on
economic growth of Italian regions. Ellis and Fender investigate the tension between the
need for the government to rectify a market failure and supply a public good, and the
opportunity that this provides for corruption. They claim that when potential governments
compete, “instead of driving corrupt payments to zero the competition leads to the
maximisation of the present discounted value of private sector utility subject to a constraint
imposed by the level of irreducable (sic) corruption” (Ellis and Fender, 2003, p.3).
On government valuation, Depken and LaFountain (2004) explore the effects of corruption
on state bond ratings in the US and find that more corrupt states have lower bond ratings,
implying that taxpayers in those states must pay a premium for debt. In East Asia, Fons
(1999) identifies a correlation between credit risk and corruption. As for the private sector,
Lee and Ng (2002) investigate the relation between corruption and international corporate
32
valuation. Their results show that firms from more (less) corrupt countries trade at
significantly lower (higher) market multiples, implying that corruption has significant
economic consequences for shareholder value. Interestingly, Fisman and Svensson (2000)
reveal that growth in the private sector is also impeded by corruption – specifically, bribery
curbs growth more than taxation in Uganda.
Corruption is also connected to competition. Emerson (2006) investigates the interaction
between corrupt government officials and industrial firms, and the results indicate that
corruption is antithetical to competition, and also that higher education and more civil
liberties (a proxy for democracy) have a mitigating effect on corruption. Compte et al.
(2005) observe that corruption can affect competition in government procurement auctions.
If the agent administering the market accepts bribes, this can result in high public spending
and inefficient allocation of resources.
On the relationship between government revenue and corruption, Hwang (2002) finds
corruption as being negatively and significantly related to domestic tax revenue as well as
total amount of government revenue over GDP. Also, Hwang states that international trade-
tax revenue as a proportion of total government revenue is negatively and significantly
related to corruption. Fjeldstad and Tungodden (2003) show that an increase in corruption
may raise revenues in the short run, but in general the opposite will be the case in the long
run. Johnson et al. (1999) present a similar argument in a slightly different manner. First,
they find that the share of the unofficial economy in GDP is higher in the presence of
tighter regulation, as this provides more opportunity for officials to employ corrupt
practices. A higher share of the unofficial economy is then correlated with lower tax
revenue as a percent of GDP, thus an increased level of corruption will lead to lower tax
revenue.
Huang and Wei (2003) analyse the implications of corruption for central banking.
According to their study, the optimal inflation targeting for a high-corruption country is
generally different from that for a low-corruption country, and that fixed exchange rates are
more difficult to sustain for high-corruption countries as the inflation rate (in the anchor
country) may be too low from the viewpoint of the countries that adopt the exchange rate
arrangements. Related to the issue of inflation, Braun and Di Tella (2004) argue that agents
33
can inflate prices for goods needed to start an investment project. High and variable
inflation is assumed to increase the cost of monitoring the agent, and this is found to result
in higher corruption and lower investment.
Alesina and Weder (2002) study the connection between corruption and foreign aid. They
could not produce any evidence that bilateral or multilateral aid goes disproportionally to
less corrupt countries. Interestingly though, their study reveals that while Australia and
Scandinavian countries give more foreign aid to less corrupt countries, the US does the
inverse. Generally, an increase in aid is found to increase corruption. Ali and Isse (2003)
concur with this relationship. However, Tavares (2003) uses geographical and cultural
distance to the donor countries as instrumental variables to assess causality between foreign
aid and corruption, and finds the inverse to be true, i.e. that foreign aid decreases
corruption.
3.3 Empirical Studies on Rent-Seeking
In Chapter 2, rent-seeking was introduced as an alternative dimension of corruption. There
is a considerable amount of literature analysing the impact of rent-seeking on an economy,
and what follows is a survey of those studies, which are also concisely summarised in Table
3A.2 in the appendix to this chapter.
3.3.1 Rent-Seeking Expenditure
Many studies have analysed the expenditure on rent-seeking, as this is deemed to be a
significant determinant of the social cost of rent-seeking (Amegashie, 1999; Baye et al.,
1999; Dixit, 1987). One might assume that the greater a player spends on rent-seeking, the
greater the player’s chances of winning the rent. However there are other factors that
influence rent-seeking expenditure. For instance, Amegashie (1999) considers a rent-
seeking scenario where part of the rent is fixed and the remainder is dependent on the
extent of lobbying. This is likened to applications for a position that is subject to a
minimum salary which may be increased depending on the quality of the successful
applicant. It is also similar to institutions that compete for a research grant which has a
minimum value for the successful institution, but the amount may be raised depending on
34
the attractiveness of the research proposal. Amegashie (1999) finds that in such cases, an
increase in the number of rent-seekers may lead to a fall in the aggregate rent-seeking
expenditure. In a later study, Amegashie (2002) reveals that the magnitude of rent-seeking
expenditure can also depend on whether the rent is being awarded by a single administrator
or a committee. Baye et al. (1999) show that, in some cases, rent-seekers may end up
spending more than the rent itself is worth.
Dixit (1987) considers a situation where individuals expend effort to increase their
probability of securing a particular rent, such as when firms compete in investment to yield
a profitable innovation, or when bribes are paid to government officials to secure a
particular licence or contract. In the case of the latter, if two contenders for the rent are not
equally efficient then Dixit (1987) argues that the more efficient user, if given first access
to the government official, would offer a higher bribe than in the case of simultaneous
access. However Glazer and Hassin (2000) find that in sequential contests, earlier movers
do not make more profits than later movers, and profits are lower than in simultaneous
contests.16
Haan and Schoonbeek (2003) contrast rent-seeking with auctions. In an auction, all players
exert effort by submitting a bid and the highest bid wins the auction. Under rent-seeking,
the outcome is stochastic. The competitors will still exert effort by lobbying or bribing but
this only serves to increase their probability of winning the rent, and decrease the
probability of their rivals winning it. In practice, Haan and Schoonbeek argue that hybrid
forms of rent-seeking contests and regular auctions exist where a bid is offered by each
competitor but other factors are also taken into account, thus allowing room for the
contestants to increase their probability of winning. They also find that there is
underdissipation of rent in these circumstances. Lockard (2003) also examines the
randomisation in the rent-seeking game and provides a detailed analysis of how this can
impact on the rent-seeking expenditures. Davis and Reilly (1998) claim that more rents are
dissipated in perfectly discriminating auctions where the highest bidder wins, than in
lotteries where relative bids determine the chance of winning.
16 See Morgan (2003) for a theoretical comparison between sequential and simultaneous contests.
35
Valuation of the rent-seeking competitors also plays a role in determining rent-seeking
behaviour. The findings of Epstein and Nitzan (2002) demonstrate that the aggregate
expected payoffs of the players are positively related to their valuation. Similarly, Baumol
(1990) argues that it is these payoffs that determine whether the players will engage in rent-
seeking behaviour. Nti (1999) shows that the probability of winning is tied to the valuations
of the contestants. The contestant with the higher valuation will exert more effort than the
lower valuation contestant but both will allocate the same fraction of their valuations to
rent-seeking. This implies that the higher valuation player becomes the favourite to win the
rent. If the favourite’s valuation increases, then he or she will exert more effort but the
other contestant will actually reduce their effort. On the other hand, if the other contestant’s
valuation is increased, then both players will increase their efforts. Expected profits
therefore increase with a player’s valuation but decrease with the valuation of the
competitor. In a similar vein, Stein (2002) shows that a player’s expenditure will depend on
the expenditure of competitors.
Vogt, Weimann and Yang (2002) argue that rent-seeking will necessarily result in an
efficient outcome. In their study, it was found that in an open-ended game players have no
control over their competitor’s response once they make a bid, but the threat of escalation
was enough to encourage the players to settle for an efficient outcome. Sometimes
competition between rent-seekers can lead to dissipation of the rent, in which case Baik and
Lee (2003) show that it is beneficial for players to combine and form a strategic group,
which will lead to lower rent dissipation than if players compete. In the context of trade
policy, Aidt (1997) finds that if players’ bargaining power is balanced, then cooperation
can lead to free trade. However if the power is unbalanced then cooperation can lead to
increased trade protection. Cooperation between consumers and workers has also been
shown to reduce social losses (Rama, 1997).
3.3.2 Rent-Seeking and Political Involvement
An important element of the rent-seeking process is the role played by the government.
Earlier, the rent-seeking process was found to result in a social loss as shown in the typical
case of a monopoly. But this loss is dependent on the size of the rent, which is ultimately
determined by the government. The firm can engage in rent-seeking behaviour not only to
36
win this rent, but also to maximise it by pressuring the government to raise the size of the
rent. However, Epstein and Nitzan (2003a) contend that the public will also exert their own
pressure on the government to keep the price (and thus the size of the rent) as low as
possible (rent-avoidance) in order to protect their surplus. In a later study, Epstein and
Nitzan (2003b) show that this consumer opposition will actually influence the monopolist’s
decision on what price to set, which will end up not being the profit-maximising price.
Faith (2002) holds a pessimistic view about rent-seeking and political involvement. If firms
seek to secure an import licence for example, competition will eventually drive these rents
down to zero, which tends to happen where rent-seeking is not actively encouraged by the
political sector (Che and Gale, 1997). Once that happens, Faith (2002) argues that rent-
seeking will jump to a higher level, where firms will try to gain control over the authority
that issues the licence. Again, if this is circumvented by legislation that may perhaps direct
all licence revenues to the treasury, firms may further engage in rent-seeking behaviour to
ensure that this revenue is spent on projects that are beneficial to the firms. Faith (2002)
suggests a way around this, by offering pools of funds to firms that are fixed, such that the
degree of rent-seeking behaviour has no impact on how much funds are available to a
particular firm. But this may not necessarily be in the government’s best interests, as it may
wish to encourage rent-seeking for efficiency reasons.17 For example, the government may
prefer a monopoly over perfect competition because there would be less rent-seeking
behaviour and therefore less wastage (Lambsdorff, 2002). However, as Lambsdorff argues,
if the size of the rent is dependent on the rent-seeking activity, then a monopoly would
result in more wastage than a competitive market. Further, in a competitive market there are
unequal degrees of rent-seeking behaviour and no guarantee that the rents will accrue to the
firm that invests the most resources in rent-seeking. And competing firms introduce an
element of product quality through availability of choice, which is non-existent in a
monopoly market. The monopolist is also not required to reveal any information about its
production efficiency, while this information would be provided by competing firms.
On the other hand, Sutter (1999) finds that if a government allows secure rights to rents,
firms may end up making political investments to create new additional rights. Related to
17 Boyce (1998) provides an in-depth analysis of the manner in which governments can allocate rents, and the impact this has on rent-seeking.
37
this point is what Tullock (1993) refers to as the ‘transitional gains trap’. This theory
suggests that if the government were to subsidise a particular industry, it would only result
in transitional gains. The entry of new firms into the market (attracted by the subsidy)
would lower whatever superior profits were being made as a result of the subsidy. The
economy will become smaller and less efficient. The problem now is that the government
would not be able to withdraw the subsidy as it would induce more rent-seeking behaviour
in order to retain the rent.
Having already invested resources into seeking a rent, firms will then engage in rent
protection to avoid the transitional gains trap. Tullock (1993) cites the Rowley and Tollison
(1986) model of rent-seeking and rent-protection, as shown in Figure 7.1 where firms
engage in rent-seeking behaviour to secure a full monopoly right, worth price A and
quantity Qm. With perfect competition, the price could be driven down to E and quantity
produced would expand to Qc. This is the outcome for which consumers would lobby the
government. Equilibrium price is therefore situated at F, which is somewhere between A
and E. The government dictates this price, as a result of lobbying from both firms and
consumers. This political price F is deliberately positioned closer to A than E, because the
lobbying power of firms is assumed to be greater than that of consumers. The cost to the
firms is represented by the rectangle FCIE, which is assumed to exceed the size of the
consumers’ cost represented by the trapezoid ABCF (all expenditures represent social
waste since society receives no benefit, only the rent-seeking firm does). The social cost of
the resulting partial monopoly is thus equal to the social cost of a full monopoly (assuming
no rent avoidance by consumers) described earlier in the discussion. Firms will continue to
lobby the government to protect their rents, and thus the government will be reluctant to
withdraw any rents.

The nature of the government has also been analysed in the literature.18 For example,
Mudambi et al. (2002) find that plurality electoral systems are more resistant to the political
demands of rent-seeking than proportional systems. They also find that having fewer
election districts reduces rent-seeking opportunities. Similarly, Spindler and de Vanssay
(2003) reveal that constitutional design has an impact on rent-seeking, and vice versa. Sato
(2003) explores the welfare impact of fiscal decentralisation in the presence of rent-
seeking, and reveals mixed results. Competition leads to lower capital tax revenue under a
decentralised government, which leads to a reduced source of available rents, but reduced
tax revenue may also stimulate further political activities. Thus the impact of
decentralisation on rent-seeking behaviour is ambiguous. Aidt (2003) finds that in the
absence of political competition, rent-seeking expenditure becomes self-limiting. An
analysis of the trade-off between private and public rent-seeking is provided in Boldrin and
Levine (2004).
3.3.3 Rent-Seeking in Specific Industries
Many studies have analysed rent-seeking with reference to particular industries. Abbot and
Brady (1999) studied the nature of rent-seeking within the US telecommunications
industry, and their findings suggest that government regulation has retarded competition
and innovation in that industry through the actions of rent-seeking agents. Law (2003) 18 McNutt (1997) uses political tenure to derive a measure of rent-seeking.
39
focuses on the oligopolistic US food industry and observes that regulation of that industry
did not arise as a result of rent-seeking, contrary to public thinking. Based on a study of the
same industry, Bhuyan (2000) finds evidence that corporate political activities (or rent-
seeking behaviour) are higher in industries that are highly concentrated, large in employee
size and sales and deeper in debt. Goel (2003) analyses rent-seeking in research markets
and finds that greater rent-seeking by a rival lowers an academic’s own profit-maximising
research and rent-seeking activity, and that greater research spending by a rival has the
same effect especially when the probability of the academic’s own innovation is low.
McMillan (2004) explores the effect of rent-seeking on public school productivity. Gramm
(2003) considers how rent-seeking affects bank mergers and acquisitions, and finds that
protests by interest groups against these impose significant time costs on merger and
acquisition applications.
Migue and Marceau (1993) study rent-seeking in the context of environmental pollution,
and consequent tax/subsidy policies. They find that pollution taxes and subsidies give rise
to rent-seeking and dissipation of rents, which adversely affects the success of anti-
pollution programs. In a similar vein, Damania (1999) finds that prevalence of pollution
emission standards is a direct result of rent-seeking behaviour, and they are more likely to
be proposed by political parties which represent environment interest groups. Torvik (2002)
studies natural resource rents, and argues that a greater amount of natural resources
increases rent-seeking and thus reduces the number of entrepreneurs running productive
firms. The consequent drop in income exceeds the increase in income from the natural
resource, thus more natural resources lead to lower welfare. In a rather obscure area of the
literature, Scully (1997) analyses rent-seeking in the context of democide and genocide, and
finds that such rent-seeking results in a 20% loss in wealth.
Banerjee (2001) provides an interesting analysis of rent-seeking in the sugarcane industry
in the Maharashtra province of India. Sugarcane farmers hold membership with a
cooperative, which agrees to buy sugar from the farmers at a uniform price before
converting the sugarcane into sugar and selling it on the market at a higher price. The board
of the cooperative consists of mainly large sugarcane farmers. The law in India prevents the
cooperative from providing its members with lump-sum transfers (resulting from profits),
so the most logical way of rewarding farmers for their efforts is to raise the price paid for
40
sugarcane. Since this is a uniform price, all farmers would benefit from this upward
adjustment in price. However, the board of the cooperative engage in what is known as
dharmodaya, where the profits earned by the cooperative are siphoned off and used for
investments (such as temples, schools, etc) which end up benefiting the board members
disproportionately. Thus, the board engages in rent-seeking behaviour by lowering the price
paid for sugarcane to maximise the available rents, and then investing the rents into projects
which ultimately benefit the board members.
Khwaja and Mian (2005) find evidence of corruption in Pakistan’s banking sector. They
have evidence that politically connected firms receive preferential treatment from
government banks. The extent of rent-seeking by these firms increases with the strength of
the politician, and falls with the degree of electoral participation in his constituency. Nearly
2% of GDP is lost to this manner of rent-seeking every year.
3.4 Conclusion
There are a multitude of studies analysing corruption’s impact on growth and, as this
chapter has shown, the overwhelming majority of them have concluded that the impact is
detrimental. However, the relationship between corruption and growth has always been
examined from a very broad perspective, both in terms of the time period in focus, and the
number of countries. The same is true for studies analysing the relationship between rent-
seeking and economic growth. Most notably, few studies have attempted to analyse the
East Asian region and, in particular, the period before the 1997 Asian Financial Crisis when
those countries were achieving high rates of economic growth in spite of similar degrees of
corruption. Within this context, even fewer studies have attempted to use rent-seeking as a
proxy for corruption. The present study will seek to fill in these gaps. However, the nature
of corruption in East Asia is an issue that is worthy of independent analysis. This will be
the subject of the next chapter.

Allocatively efficient default policy does not minimise social costs, and maximises rent-seeking. Competitive post-allocation market reduces rent-seeking, but does not minimise social cost even with an efficient default policy. But forcing winners in political redistributions to compensate losers achieves efficient allocation with zero rent-seeking.

Emerson (2002) Rent-seeking in less developed countries
The high degree of corruption in developing country governments contributes to the dual nature of their industrial structure. The higher the degree of corruption, the fewer (and larger) are the formal firms, the lower is social welfare and the greater is dead-weight loss, and the higher are government rents. An examination of the size distribution of 16 countries and their degree of corruption shows that the degree of corruption is a good predictor of the percentage of large firms in an economy.

Faith (2002) Rent-seeking and fixed-share pools in government
A fixed-share pool is a given amount of resources to be divided among a given number of claimants. Each share is fixed so there is no rent-seeking. However, if claimants have sharing rights to more than one pool, rent-seeking in the form of transferring resources from a pool where one has a small share to a pool where one has a large share will generally occur.

CHAPTER 4
CORRUPTION IN EAST ASIA
You cannot expect your civil servants to be totally clean when you
underpay them, underpay your civil servants in relation to what the
market is paying the rest of the community.
- Chief Executive of Hong Kong SAR Donald Tsang.19
4.1 Introduction
The focus of this study is on corruption in East Asia before the 1997 Asian Financial Crisis.
Only a handful of studies have attempted to show that corruption in East Asia resonates
with the concept of rent-seeking, and presents an argument for using rent-seeking as an
alternative to the Shleifer and Vishny (1993) principal-agent model in the analysis of
corruption. At a broader level, there is also an argument for revising the perception that
corruption is synonymous only with bribe paying. What follows is a concise review of the
few studies in this strand of the literature, and their application of the rent-seeking model to
explain East Asian corruption is quite telling. It is shown that the corruption within East
Asia is of a complex and diverse nature.
4.2 Cronyism
To begin with, one needs to remember that Asian business and politics was plagued by
cronyism and nepotism, and as Kang (2003) explains, this is an example of how rent-
seeking behaviour can enhance efficiency in an economy. The rent-seeking model
discussed in Chapter 2 incorporated an element of political involvement. In other words the
government is no longer free of any responsibility as in the Shleifer and Vishny (1993)
model, rather it has a direct role to play in determining the rents available and how they are
transferred. The situation can also be reversed – the government can extract rents from the
private sector and transfer them back into the economy.
19 Keatley (2006, p.6).

Kang (2003) links cronyism with rent-seeking particularly in Asia. Cronyism refers to
family and personal relations, bribery and corruption, patron-client relations and collusion.
It occurs when preference is given to friends or colleagues, resulting in a potential conflict
of interest (Gyimah-Boadi, 2000). According to Khatri et al. (2006), cronyism requires that
one party offers something of value to another, implicitly requiring a reciprocal exchange,
where both parties are connected in some form of social network (e.g. friendship, kinship,
etc). What makes this a cost to society is when this exchange is at a cost to a third party,
who holds a superior claim to the valued resource. When cronyism is mixed with
government and politics, it is seen as an impediment to economic growth because it implies
that decisions are based upon non-market principles, and involves rent-seeking. Kang
(2003) primarily argues that cronyism can reduce transaction costs, particularly in
developing countries where such costs to doing business are prohibitively high. Most
developing countries have relatively weaker legal, political, and economic institutions than
developed countries, so information about market conditions and potential is scarce and
difficult to obtain, thus making investments and property rights insecure. Further, long-term
commitments become less appealing because of the risk of political and economic
conditions and actors changing quickly. Capital markets also do not function efficiently in
developing countries, which introduces an element of uncertainty into political or economic
decision-making. Lloyd-Ellis and Marceau (2003) show that in the early stages of
economic development, these credit market imperfections will actually induce rent-seeking.
Once the economy develops, productive activities become more secure and profitable and
rent-seeking is abandoned.
In the case of Asia, cronyism offers a way to circumvent all of these problems. Cronyism is
synonymous with guanxi, a Chinese word literally meaning ‘connection’ or ‘relationship’
(Khatri et al., 2006). These close personal relationships offer a level of trust that is lacking
elsewhere, which leads to better information and ability to enter into long-term contracts.
Further, cronyism can actually reduce transaction costs. Kang (2003) asserts that the parties
involved in cronyism are mutual hostages of each other – in other words, each party
(political and business elite) has the ability to harm the other but is deterred by the damage
that can be inflicted by the other. Rent-seeking costs can be lower if the business elite
operates in the form of a cartel, since the consequent collusion reduces the extent of
69
competition for rents and thus reduces the investment of resources towards rent-seeking
(Baik and Lee, 2001).
Within East Asia two polar examples of cronyism can be identified. Where there are an
excessively large number of parties, the result is chaotic. Economic policies will fluctuate
wildly as players try to side with the ruling party, and the investment environment in
general will be unpredictable so transaction costs will be high. This was largely the
situation in the Philippines. At the other extreme, there is only one centralised player with
whom all other players try to side, an example of which is Indonesia. On the surface,
economic decisions can be made quickly and efficiently, and implementation is just as easy
because players only need to deal with one party. However, this stability is offset by the
risk of less durability through a crisis or a transition period. Such periods can threaten
stability of the ruling party, which then raises transaction costs and renders property rights
meaningless. Much of the cronyism in East Asia involved intermarriage among elites. Once
the ruling political party had established itself, the business sector was allowed to influence
policy decisions, so access to the state was the key to economic success (Kang, 2003).
Moran (1998) makes an interesting observation about the study of corruption and rent-
seeking with respect to Asia. The extant literature according to Moran (1998) tends to
restrict corruption to the political elite, which took kickbacks by virtue of their position and
power but were in no way connected to the bureaucracy. In fact, the bureaucracy was
deeply intertwined with the political elite and was itself corrupt. Kong (2004) expands on
this point, drawing a distinction between the neoclassical approach to corruption and the
political power approach. The former is more widely acknowledged in the literature, and
regards corruption as a result of excessive government intervention that results in market
distortions. To rid countries of corruption, neoclassicists argue that these countries should
expand the scope of the market and model their political and economic institutions on those
of Western market democracies. But Kong (2004) argues that this erroneously views
corruption as a homogenous phenomenon, and does not provide an answer to the question
of why some countries are developmental orientated in spite of high levels of corruption?
Under the political power approach, Kong (2004) suggests that corruption should be
viewed from both a political and an economic perspective, and understood within the
context of historical conditions and political power contestation and distribution. This
70
would be more accurate in the case of East Asia. In fact, it highlights the difference
between neoliberalism, where a free market democracy is the means and end of
development, and developmentalism, where a market democracy is achieved but only after
some illiberal means are employed along the way.
Using the political power approach, Kong (2004) shows that in East Asia there was an
asymmetrical distribution of political power in favour of the executive. In South Asia
however, this distribution of power was not only between the government and business
sector but also between the government and the middle class. This yielded a secondary set
of patron-client networks in addition to the state-business relationship. But in the case of
East Asia, the government could make the most of its relationship with the business sector,
maximising rents by encouraging growth (ensuring that firms performed well), without
worrying about having to make payments to a third party (e.g. the middle class in the case
of South Asia). The point to be made here is that as long as corruption or rent-seeking is
centralised, it is not a hindrance to economic development. This point will be examined in
a later section.
4.3 Mutual Hostage Situations
In the case of South Korea, a mutual hostage situation existed between the business sector
and the state which led to enhanced growth, but not before the corrupt rule of Syngman
Rhee hampered growth in the 1950s. Rhee was receiving substantial foreign aid from the
US in return for being an anti-communist ally, and also milked the private sector in
exchange for providing rents in the form of licences to import scarce goods, control of
Japanese firms at undervalued prices, etc. All the proceeds went straight to Rhee, his
political party and the police bureaucracy (Moran, 1998).
A mutual hostage situation between the state and the private sector began to develop when
Park Chung Hee came to power via a coup in 1961. Park implemented a Japanese style of
corporatism in South Korea where national development was intertwined with social
cohesion (Kang, 2003). Unlike the British, the Japanese did not rule by having local
supporters and administrators. Instead, they used Japanese colonial administrators who
transferred over a quarter of South Korea’s arable land to Japanese entrepreneurs and
71
corporations. The aim was to convert South Korea into a productive base for Japan, instead
of maintaining it as a captive market at a low cost like the British did (Khan, 2000b). All
this meant that sectional interests were to be marginalised, and both the labour force and the
private sector needed to accept the state authority in favour of national development. Those
businesses that followed government guidelines and shifted to export-led growth received
benefits from the government. Some businesses received assistance by virtue of their
regional origins or personal relationships with the government elite, but this assistance was
quickly reduced or withdrawn upon signs of weak performance. Against this backdrop,
civil society groups were also weak and marginalised. This autonomy from civil society
groups allowed South Korea to nationalise corruption (Moran, 1998).
Initially, businesses were keen to stay on the right side of the government, and thus patron-
client networks were established. Under Korea’s first five-year economic development plan
in 1962, the government encouraged business activities amongst entrepreneurs, providing
public support and subsidise to those who made investments in preferred industries. Added
to this was an environment of rising foreign investment as a result of US pressure on South
Korea to shift to export-oriented industries in order to lower US foreign aid. As private
finance flowed into South Korea, rent-seeking behaviour from foreign corporations saw
over US$8 million of funds being diverted to the ruling party during the 1971 elections, in
attempts to secure participation in the profitable economic conditions (Lee and McNulty,
2003; Moran, 1998). Thus Korean businesses (or chaebol) were highly leveraged and relied
upon the government for finance. This reflects the centralisation of corruption in South
Korea as outlined in the Shleifer and Vishny (1993) model. According to the model, if
bureaucrats work together or collude in the offering of bribes, it is possible for the
aggregate level of bribes to be maximised, instead of maximising individual bribes (which
would ultimately reduce total output). At the same time, the government wanted to
encourage the formation of large conglomerate firms which were accounting for large
percentages of the South Korean economy. The chaebols needed the government for
finance, but the government could never threaten to cut off credit because of the effect it
would have on the economy. Further, politicians relied upon the chaebols for financing
their campaigns (Kang, 2003). Thus the balance had started to tip in the chaebols’ favour,
and they began to possess and exercise more power, giving them advantages over smaller
firms in almost all aspects of business activities and jeopardising the interests of suppliers,
72
competitors, and customers. In 1996, the 30 largest chaebols accounted for 40% of
shipments, 18.1% of employment, and 38.2% of value added in the mining and
manufacturing sector (Shin, 2002). The corruption that existed in South Korea was
motivated by political survival and individual greed, and resulted in economic development
because of the mutual hostage situation between the government and the chaebols. Once
democratisation began to take hold, the business sector began to exert more control
resulting in a situation of state capture.
4.4 Centralised vs Decentralised Corruption
In the Philippines however, in the early period of democracy, there was no mutual hostage
situation. The business sector would establish close ties with the ruling party (which
happened to be just as weak as the opposition), and once the rulers failed to deliver, the
support would wane and shift toward the opposition. Thus political power consistently
swung between both sides, with the business sector milking each for its own benefit.
Essentially, the politicians were buying votes from the business sector. This is reflected by
excessive budget deficits in election years (Kang, 2003).
Between 1971 and 1997, the Philippine economy grew at an average of 3.8% per year
(World Bank, 2005). This is significantly lower than the average growth of its Asian
neighbours, and it is largely due to the decentralised corruption that prevailed. Shleifer and
Vishny (1993) asserted that when complementary goods (say, fire and water and police
department licences sought after by a builder) are being offered by a single bureaucrat, the
bribe charged for the first good will not be set too high as it may reduce demand for the
second good. In other words, centralisation forces the corrupt official to consider aggregate
rent collection instead of individual bribes. But if the complementary goods were being
sold by two different competing bureaucrats, each would seek to maximise his own bribes
and this could result in lower aggregate rent collection. Thus, decentralised corruption
results in greater inefficiencies. In the Philippines in 1968, it was found that an entrepreneur
would need to go through 54 procedural steps in order to release an importation, of which
42 involved the payment of a bribe. The bureaucracy in the Philippines was not subject to
centralisation as far as corruption was concerned, largely because the elite had a strong
economic base outside of the state, unlike in Indonesia and Thailand for example
73
(Hutchcroft, 2000). Without centralisation, an element of unpredictability was introduced in
dealings with the bribery within the bureaucracy and therefore transaction costs for
businesses were increased along with inefficiency.
Like in South Korea, the Philippine business sector was driven by family based
conglomerates, but the difference was that there was more than one family. This raised
transaction costs and lowered economic efficiency for three reasons. First, rent-seeking
costs were much higher because of the increased competition. Second, the increased
competition also meant that property rights were unstable. And third, demands on the state
were increased due to the different competing families and the impediments to collusion
(geographical amongst others) (Kang, 2003). There was also weak monitoring of rents, so
firms were not given an incentive to invest the rents productively. Once Marcos came to
power in the Philippines, the cronyism became less decentralised as he capitalised upon a
disorganised business sector and created oligarchs that depended upon him for survival. But
Marcos never instituted restrictions on his power or those of his cronies, so the rent-seeking
behaviour became unproductive and highly inefficient (Hutchcroft, 2000). Once again there
was no mutual hostage situation, so the Marcos government simply preyed on the economy
and sought to maximise its own rents without any regard for development.
While Marcos failed, Suharto succeeded. Indonesia’s case is a perfect example of
centralised corruption. Under the rule of President Suharto from 1966-1998, the Indonesian
economy was quite literally transformed from rags to riches. Unlike in the Philippines, the
ruling regime had incentives to prevent unrestrained plundering and inefficiency once it had
established itself as an authoritarian power. The Suharto government most notably
implemented a policy of balanced budgeting, promising not to spend more than what was
collected from tax revenue and foreign aid. The Suharto era was punctuated with fiscal
discipline, and even the government spending itself was equitable and positive in terms of
distribution of wealth. However, beyond the apparent discipline lay a substantial degree of
off-budget fiscal activity. A major example of this was Suharto’s control over Pertamina,
the state oil company. Its profits were siphoned off by Suharto and used to finance
industrial development plans that were largely unsuccessful until the central bank was
eventually called in to bail out the firm and pay off the significant debt that was owing to
international creditors (MacIntyre, 2000).
74
The use of state enterprises to finance government projects was one form of off-budget
fiscal activity, that also had inflationary effects given that the central bank was one of the
state organisations involved. In addition to this, private firms were also encouraged
(unofficially) to contribute to similar government projects. In some cases, wealthy
businessmen contributed funds to assist the government by undertaking financially
pessimistic projects, purely and simply to maintain patron-client relations with the Suharto
government and indeed Suharto himself (MacIntyre, 2000). Even members of the political
elite competed amongst themselves to partake in Suharto’s spoils. The business sector in
Indonesia was never allowed to organise and develop a strong base, instead it had to rely
wholly on the ruling Suharto family for survival. This was partly due to the ethnic
breakdown of the business sector. The ethnic Chinese minority in Indonesia was less than
4% of the population yet held the majority of the private sector. Due to their minority
status, the Chinese capitalists were politically vulnerable and had no choice but to look to
Suharto for protection. This is in stark contrast to the South Korean chaebols, which never
suffered any social resistance and did not need the government’s protection (Kang, 2003).
From 1966 to 1997, before the advent of the Asian financial crisis, Indonesia averaged
growth of over 7 per cent per year. In the five years preceding Suharto’s takeover, growth
only averaged 2 per cent per year (World Bank, 2005). Despite the excessive rent-seeking,
the economy was still able to achieve high growth rates. The key to this lies in the
aforementioned incentives in restraining plundering and excessive inefficiency. Once again,
using the Shleifer and Vishny (1993) model, when complementary goods are being
provided by the same bureaucrat the level of the bribe extorted will be kept down in order
to maximise overall rent collection. Suharto was effectively a monopolist in this context,
and was careful not to allow excessive and unrestricted corruption which would have had a
detrimental effect on aggregate rent collection. In one case, a member of the political elite
wanted to fund a jet aircraft project and sought assistance from Suharto. Despite allowing
the project to go ahead, Suharto imposed two restrictions. While it would have been easy to
pull funds from the budget or from the government’s hidden reserves (unofficial bank
accounts), Suharto ensured that the funds came from off-budget sources. This restricted the
size of the funds. Secondly, a respected and independent member of the cabinet (not a
crony of the project’s founder) was placed in charge of managing the funds, so as to ensure
arm’s length accounting (MacIntyre, 2000).
75
In another case, Suharto’s grandson Ari Sigit used his corporation as a middleman to help
provide shoes for Indonesian schoolchildren. In an agreement reached with the Education
Department, schoolchildren were obligated to purchase shoes from Ari Sigit’s company at
an above-market price which would have yielded profits of around US$80 million a year.
The public were furious that the president’s grandson was ripping off poor Indonesian
families, and the public outcry eventually saw Suharto disapprove the plan and force the
Education Department to abandon it (Backman, 1999). These cases reflect Suharto’s
awareness of his centralised position and the need to ensure that no single sector enriched
itself at the expense of the entire pyramid, atop which Suharto sat (MacIntyre, 2000).
4.5 Patron-Client Networks
Connections have always been important in Asia. According to Luo (2002) illicit business-
government links are important in the analysis of corruption in Asia. But these connections
do not necessarily operate in the same way. For example, where the government of South
Korea had to deal with rival political elites, consequent political contestation, and a
distinction between state and business, the Taiwanese government did not have to contend
with the same factors. Taiwanese political leaders allowed relatively little direct private-
sector input in policy-making decisions, and instead chose to establish political ties with
small and medium sized enterprises and farmers (Byun, 2001). The ruling Chinese
Nationalist Party or kuomintang (KMT) was never impeded the way governments were in
South Asia (as discussed above) because the local elite was kept divided and was never
allowed to collude. The competition amongst the local elite for government ‘side payments’
limited their influence over rent collection from the KMT. While in South Korea, the
business sector gained significant bargaining power after democratisation, in Taiwan the
situation was somewhat more chaotic. Since the KMT controlled a significant proportion of
the business sector, it maintained a position as a powerful business force. But the sheer
quantity of assets that were available to be appropriated by the private sector introduced
several other players into the game, including underground criminal organisations. This
gave rise to a web of connections between the different players (Kong, 2004).
Patron-client networks were established all over East Asia in many different ways. In
76
Thailand, the ruling elite had strong roots within the bureaucracy unlike in the Philippines.
However, there was still excessive corruption within the bureaucracy due to separate
factions within the elite. The Thai Chinese played a role similar to the Malaysian Chinese,
but the difference was that they intermarried with the locals and were linguistically
integrated. There was effectively a three-way power tussle between the military-
bureaucratic group, the Bangkok-based Thai Chinese capitalists, and provincial capitalists
(Khan, 2000b). This meant that the bureaucracy, although centralised, was weak,
fragmented and not oriented towards development unlike in South Korea. The military-
bureaucratic group had held power in the 1950s, but as the regime shifted towards
democracy in recent years the power of provincial constituencies (providing 80% of seats
in the House of Representatives) increased and provided opportunities for patron-client
networks. Although competition for power amongst the elite was a recipe for disaster in the
case of the Philippines, in Thailand the difference was that the bureaucracy was the source
of power and prestige, whereas the Philippine elite already had an economic base outside
the state. Fortunately, the macroeconomic management of the Thai economy was entrusted
to a few agencies that were insulated from bureaucratic politics, and thus was enable to
enforce fiscal discipline (Rock, 2000).
In the midst of this power tussle, the Thai Chinese entrepreneurs (who were excluded from
the public and political arenas prior to the 1970s) began to capitalise upon patron-client
relations with the military and sought protection from harassment by bribe-seeking
bureaucrats in return for offering financial support. Rent-seeking became highly
competitive and there was consistent entry into rent-providing industrial sectors by
excluded capitalists (both ethnic Thai and Thai Chinese), seeking to establish links with
members of the ethnic Thai elite (Doner and Ramsay, 2000). These patron-client networks
ultimately contributed to economic growth, which averaged over 7% per year between
1971 and 1990, and then nearly 9% in the first half of the 1990s (World Bank, 2005). The
contribution is no more evident than in Thailand’s massive textile industry. Several textile
firms were established in the 1950s by commercial bankers, who had links to the ruling
military through their banks. By 1960, there were 20 such firms founded by 16 groups of
investors. This was followed by the government passing legislation to protect property
rights in the pursuance of an import-substitution policy. This allowed the textile firms to
form alliances with foreign (mainly Japanese) firms and further enhance their property
77
rights. With the factional rivalry within the elite, new capitalists entered the scene and
increased competition for rents. While larger established firms used their political
connections to seek restrictions on textile capacity to protect their interest, newer firms used
their own connections to circumvent these restrictions. Competition eventually led to an
oversupply in the domestic market. Fortunately, cooperation between the private sector as a
whole and the government eventually led to exporting in the 1970s (Doner and Ramsay,
2000).
The entrance into exporting led to the problem of allocation of export quotas to competing
firms. The government ended up allocating quotas on the basis of past exports – those who
exported more were given greater quotas. Consequently, larger established firms with
strong political connections received the most quotas. However, they also tended to be
more inefficient than smaller firms (Doner and Ramsay, 2000). One reason for this is that
the technology needed to enhance productivity was so basic that the rents did not require
learning and monitoring for the adoption of the technology and efficient operation (Khan,
2000b). As the business sector strengthened itself, and as Thailand shifted towards a
democracy, the business sector (dominated by large family-based composites) began to use
electoral politics to further its own interests. Government control of trade associations
declined and their representatives made their way into the public sector (Rock, 2000). The
situation is now similar to South Korea.
4.6 Malaysia’s Rent-Seeking Experience
The creation and distribution of rents in Malaysia stem largely from the implementation of
the New Economic Policy (NEP) by the government in 1971. This policy was aimed at
removing inter-ethnic economic disparities between the majority Malays and the minority
Chinese which led to riots in May 1969 (Abu Bakar and Hasan, 2003). These disparities
stretch as far back as Malaysia’s colonial days. The Malays had always been marginalised
from the capitalist sector, and were largely involved with the rural sector except for the elite
Malays who helped form the state administration. The Chinese were, and still are, more
involved with the private sector and took advantage of business opportunities. During
colonial times, land and other natural resources were controlled by the British and were
allocated to mainly European (instead of Chinese) interests. The Malays were appeased
78
(though some might argue bribed) by pensions, positions in the state administration and
even privileged access to those same resources. Naturally, larger concessions of better land
went into British hands, and thus received better infrastructure development. Malaysia
inherited this property rights regime from its colonisers. In summary, the Malays welcomed
the government’s NEP while the Chinese remained sceptical as the government
intervention seemed to come at their expense (Jomo and Gomez, 2000).
State intervention was a necessary component of the NEP which sought to achieve inter-
ethnic parity in occupations and corporate wealth ownership. The government intervened
primarily in fiscal resource allocation, public sector ownership and control of business
enterprises. A large number of public enterprises were established in all economic sectors,
either as statutory bodies established by legislation or as private corporations (Rasiah and
Shari, 2001). Many had subsidiaries and joint ventures. The number of such entities grew
from 109 in 1970 to 1,014 in 1985, and were often charged with increasing public debt and
being inefficient. At the same time, the public sector share of GNP had increased from 29%
in 1970 to about 58% in 1981, but later fell to 25% in 1993. The contribution of state-
owned enterprises to economic growth also declined, and its capital productivity has
steadily decreased. These entities were also weak in transparency and accountability. Out of
900 such enterprises identified in 1984, annual returns were only available for 269, which
themselves reported an annual loss of RM137.3 million. This represents inefficient state
intervention that was geared towards (necessarily, as some might argue) favouring the
politically dominant but economically weak Malay community (Jomo and Gomez, 2000).
Following the implementation of the NEP, economic growth for Malaysia surged to record
levels. Between 1961 (four years after independence) and 1970 Malaysia was averaging
growth of 6.5% per year. In the next four years under the NEP, average annual growth
jumped to 8.8% (World Bank, 2005). By this stage, oil prices were beginning to rise rapidly
and the government began to tap into significant natural resource rents, although the oil
shock in 1975 saw growth plummet to 0.8% in that year for Malaysia (World Bank, 2005).
Maximisation of these rents was not only efficient but socially beneficial. To explain this,
Khan (2000a) considers the case of a lake that produces fish as an example. If one assumes
the rate of renewal of fish in the lake is fixed, then increasing the rate at which the fish are
extracted raises the marginal cost. To ensure efficient allocation of resources, the amount of
If the lake did not belong to the fishery, then anyone would be free to extract fish from the
lake. Whatever rents would accrue to the fishery would then be dissipated as a result of
overfishing. As the quantity of fish extracted rises beyond Q1, the marginal cost exceeds the
price so the total rent is reduced depending on the extent of overfishing. Each fisherman
will keep fishing as long as the price of selling the last fish covers the cost of catching it. If
there are a large number of fishermen and fish, then the cost of the last fish will appear to
be the average cost. No fisherman would be concerned with the marginal cost, and the
quantity extracted would amount to Q2, where price equals average cost. Now the total rent
accrued by the fishery is the triangle ABC minus the negative rent as a result of
competition, represented by the triangle CDE. The total rent could be zero or quite possibly
negative. This demonstrates the need for maintaining scarcity rents through the creation of
property rights (Khan, 2000a).
Source: Khan (2000a, p.34).
Q1 Q2 Output (fish)
fish extracted should be such that the marginal cost equals the marginal benefit, as
illustrated in Figure 4.1. The demand curve is assumed to be flat, because the particular
lake in question represents a small component of the total demand for fish. For efficient
allocation of resources, Q1 worth of fish should be extracted, i.e. where marginal cost
equals price. The fishery therefore earns a rent represented by the triangle ABC, similar to a

Figure 4.1: Natural Resource Rents

80
According to Jomo and Gomez (2000), two natural resource industries stand out in the case
of Malaysia; petroleum and logging. Malaysia became a net oil exporter since the mid-
1970s. In 1974 against the backdrop of rising oil prices, legislation was passed to give the
federal government jurisdiction over petroleum resources. These resources were hitherto in
the hands of state governments, along with other natural resources such as land, water,
forests and minerals, under the post-colonial federal constitution. Although the government
distributed petroleum royalties among the states, the national petroleum corporation
Petronas was in the hands of the federal government along with petroleum revenues.
Petronas is a corporation with a strong international credit rating, ranking 28th in the 2004
Fortune Global 500 (Petronas, 2004a) and raking in nearly US$10 billion in before-tax
profits in 2004 (Petronas, 2004). However, Petronas was used by the government to finance
commercially unviable projects such as the Dayabumi project in the mid-1980s and the
Kuala Lumpur City Centre (the ‘Twin Towers’) which was the world’s tallest building in
the mid-1990s. Petronas was also involved in the bailing out of Bank Bumiputra Malaysia
Berhad on two separate occasions. This has not significantly affected Petronas’ standing in
the business community largely because of its success in capturing and retaining petroleum
rents (Jomo and Gomez, 2000).
The story is not quite the same for the logging industry. Logging companies are not taxed
greatly, thus making it difficult to accommodate the real costs of reforestation and the
enforcement of logging-related regulations. Timber companies do not pay much income
tax. Jomo and Gomez (2000) assert that their financial statements reveal losses or modest
profits. State governments receive a royalty on logs extracted of some 1% of the timber
price. Loggers therefore minimise their tax liabilities and maximise retained earnings by
undervaluing the type, nature, quality, and volume/quantity of timber extracted. Extraction
and exportation of wood is often accompanied with some bribery of officials to reduce tax
liabilities. In response to this, the government raised taxes, but this only increased tax
evasion (Jomo and Gomez, 2000).
Along with increased state intervention, measures were being taken to increase Malay
participation in commerce as part of the NEP. In 1975, legislation was passed to give the
government greater control over manufacturing enterprises. Manufacturing licences could
be revoked if Malays were not being employed in sufficient numbers, or being given
81
sufficient control of corporations (Rasiah and Shari, 2001). The latter was achieved by
inducing corporations to sell discounted shares to Malays. Similar legislation applied to
foreign-owned corporations. Protests by the Chinese led the government to eventually
provide some concessions, without altering the fundamental purpose of the legislation.
Despite this, many Chinese elected to conceal the extent of their investments by setting up
complicated cross-holding networks, while others diversified their operations overseas, and
some pooled their resources together. It became necessary for both Chinese and foreign
corporations to forge close business ties with politically influential Malays (Jomo and
Gomez, 2000). It should however be noted that although the government attempted to
increase the Malay share in commerce from 2% to 30% by 1990, the target for the Chinese
share was set at 40% – which was not only above that of the Malays, but was also above the
level enjoyed by the Chinese at the time of the implementation of the NEP. The remaining
30% was the target for the foreign share, which was at 65% when the NEP was
implemented (Snodgrass, 1995). Between 1976 and 1984 growth averaged nearly 8% per
year, before a recession struck in 1985 and 1986. After the recession, growth surged once
again averaging nearly 9% until the impact of the Asian financial crisis in 1998 (World
Bank, 2005).
As part of its redistributive policies, patron-client networks were set up by the ruling United
Malays National Organization (UMNO), established after the 1969 riots. UMNO became
the dominant Malay party in the ruling coalition (Barisan Nasional). The objective of the
patron-client networks was to transfer rents from the Chinese capitalists to the political
leadership of UMNO, via legal taxes and illegal extractions. These were then used to
provide jobs for Malays in state owned enterprises and subsidised loans through the
banking system. Given the natural dominance held by the Chinese in the private sector, the
rents collected through legal taxes were already large enough and the need for illegal
extractions was less. The political Malay elite who were the recipients of these rents, later
engaged in their own rent-seeking behaviour to maintain their political support amongst the
wider Malay community (Khan, 2000b). The effect of the rent transfer from the Chinese to
the Malays occurred in a similar fashion to what was illustrated in Figure 2.7 in Chapter 2.
Fortunately for Malaysia, the implementation of the NEP did not dampen the confidence of
the Chinese capitalists, and they realised that they had no choice but to adapt to the
82
changing economic climate (Snodgrass, 1995). The Chinese continued to drive the
economy, and at the same time, the rents that were being transferred to the Malays resulted
in learning despite less monitoring by the government than was in the case of South Korea
(Khan, 2000b). The privatisation of the public monopolies created a “new rentier elite”
(Jomo and Gomez, 2000, p.295) in the corporate sector, not just politically influential and
economically powerful, but also forced to be more competent in order to maximise rents.
The massive North-South Highway project was completed well ahead of time by the
company (inexperienced in road construction) that secured the tender, in order to collect
tolls sooner. Thus rent-seeking and re-allocation of rents was efficiency enhancing for
Malaysia, and helped the economy to grow. However, since the rents were being
transferred to an intermediate, politically powerful Malay class, this restricted access to
resources by Chinese capitalists that would have otherwise induced learning on their part.
This explains why technological progress in Malaysia depended heavily on foreign direct
investment (Khan, 2000b).
The rents that were transferred from the Chinese to the Malays were also in the form of
subsidised loans from banks. Financial sector rents in Malaysia need to be understood in
the context of financial restraint, rather than financial repression. The latter involves the
government extracting rents from the financial sector. The former involves the government
creating rent opportunities for the financial sector. It is the more efficient of the two, and is
what prevails in Malaysia. The government created rents, and allowed the private sector to
compete in securing those rents. Thus the efficiency of resource allocation is left to the
private sector agents (Fay and Jomo, 2000).
Fay and Jomo (2000) illustrate how interest rate controls can lead to the creation of
financial sector rents in Figure 4.2. The equilibrium interest rate is r0, where the household
funds’ supply curve intersects the corporate funds’ demand curve. If the government was to
intervene and regulate deposit rates, rents can be captured by financial intermediaries,
defined as the difference between the lending rate, rL, and the deposit rate, rd. The lending
rate is higher than what it would be in the absence of government intervention, allowing
banks to capture rents from both the private sector (rL – r0) and households (r0 – rd).
83
Figure 4.2: Market for Loans
r

The rent effect of financial restraint is quite large. As banks recognise the rents that are
available, they will seek to capture these rents by inducing greater savings by households
by providing greater security for deposits. This is based on the notion that deposit security
dominates interest rates as an incentive for households to save. Fay and Jomo (2000)
illustrate the result of this effect in Figure 4.3.
Figure 4.3: Rent Effect of Financial Restraint
r
Source: Fay and Jomo (2000, p.307). The increased savings is represented by a shift in the supply curve from S to S1 which leads
to a new equilibrium rate of rL1. Assuming the deposit rate is still controlled by the
government, banks are able to capture rents equal to rL1 – rd. Under this scenario, firms are
actually better off because they are receiving a greater quantity of loans (Qd > Q0) at a
much lower interest rate (rL1 < r0). Through government regulation, competition which

would have eliminated these rents was restricted. Banks enjoyed an interest margin
(between lending and deposit rates) of between 4 and 5 per cent between 1984 and 1995. In
accordance with the government’s policy along inter-ethnic lines, priority lending
guidelines were also imposed on banks. Certain sectors of the economy were given access
to funds at reasonable costs, such as the Malay business community, small businesses,
housing etc. After deregulation, although the number of priority sectors declined the Malay
business community’s priority status was not affected, and was instead subject to a target of
20 per cent of outstanding loans (Fay and Jomo, 2000).
4.7 Singapore’s Secret
One country that is noticeably missing from the preceding discussion of East Asian
corruption is Singapore. As will be seen in Chapters 5 and 6, Singapore is a striking outlier
in the corruption data for East Asia. For all intents and purposes, Singapore appears to be
the cleanest Asian country and consistently boasts corruption rankings more akin to those
of the Nordic countries rather than its neighbouring counterparts. Few studies have
analysed the Singaporean experience, but Sam (2005) points to a number of features that
underlie Singapore’s secret to combating graft. Firstly, Singapore pays competitive salaries
to its public sector officials, reducing the distinction prevalent in many other countries
between the public and private sectors. The Singaporean bureaucracy is also extremely
efficient, providing simple easy-to-follow procedures that reduce the opportunity for firms
to bribe civil servants. Finally, strong political will and tough anti-corruption laws have
enabled the tiny city-state to remain relatively free of the corruption that has plagued its
neighbours.
4.8 The China Syndrome
The preceding sections have attempted to show how corruption in East Asia is more
synonymous with rent-seeking than it is with ordinary bribe paying. One exception to this
however is the case of China. Corruption through rent-seeking prevails in China, where
public agents seek profits generated by their monopolies over certain resources or power
85
for their own gains, however Chinese bureaucrats allegedly extort bribes as well.20 Lu
(1999) points to three common practices by state agencies: illicitly levied fines; imposed
fees; and apportionments. These agencies perform services for a fee when in fact they
should be provided free of charge. Most of these charges are also imposed without
accompanying legislation. These so-called ‘extrabudgetary funds’ were estimated at 38.43
billion yuan in 1995, and 42 billion yuan in 1997. What makes these even more striking is
that although the private sector pays such huge amounts, the revenues of the state treasury
are in fact decreasing, losing approximately 100 billion yuan in tax revenue each year due
to tax evasion and under-reporting of profits. This appropriation of rents also takes place in
rural China, accounting for an average of 2.5 percent of peasants’ annual income in 1991.
In Shanxi province in 1992, some villages were paying 13.98 percent of their income to
various agencies, while in Henan province in 1991 it was over 15%. The government
agencies ranged from finance, land management, and town planning to water conservation,
public health, law enforcement and postal services (Lu, 1999). China is a very special case,
and warrants a separate independent analysis due to its unique characteristics. Such an
analysis is beyond the scope of this study.
4.9 Conclusion
This chapter has reviewed the peculiar nature of corruption in East Asia. Corruption has
manifested itself in different ways across the region, however the preceding discussion has
shown that the rent-seeking model is rather successful in explaining the corruption in East
Asia. This provides the basis for using rent-seeking as a proxy for corruption in a
corruption-growth model. Before any empirical analysis can be embarked upon, a
measurement of corruption must be developed. This is the subject of the next chapter.
20 See Su and Littlefield (2001) for an analysis of rent-seeking in China and how it is reconciled with the concept of guanxi, or the interpersonal relationships or connections that are often used to seek ‘favours’.

CHAPTER 5
MEASURING CORRUPTION
“Corruption is not a natural disaster: it is the cold, calculated theft of
opportunity from the men, women and children around the world who are
least able to protect themselves. It must be taken seriously.”
- Transparency International’s Chief Executive David Nussbaum (2005).
5.1 Introduction
By virtue of its clandestine nature, corruption is not easily measurable. In fact, this has been
the greatest limitation to empirical research into this phenomenon. How does one measure
the extent of bribery in a country? Or the extent of patron-client networks that exist
between the government and the private sector? Such data is not easily available. One
reason has already been mentioned, that corruption is clandestine in nature and not visible.
Another reason is that governments of corruption nations would not be the first to publish
statistics revealing their corrupt practices to the rest of the world. The onus naturally lies
therefore on independent organisations to make their own assessments. There exist only a
handful of such sources that have attempted to provide reliable measures of corruption, and
these take the form of indices which rank countries on the basis of their corruption ‘scores’.
These indices will later be used in revised form in the empirical component of this study.
The purpose of this chapter is to critically analyse these indices and identify the best
possible index or combination of indices.
5.2 Corruption Indices
In the empirical studies involving corruption, the overwhelming majority has relied upon
one of the following six indices published by various international organisations as a
measure of corruption. Each of these indices is discussed in this section:
• the Corruption Perceptions Index (CPI) published by Transparency International
(TI);
87
• the International Country Risk Guide (ICRG) published by Political Risk Services
Inc.;
• the Business International index (BI - now incorporated into the Economist
Intelligence Unit’s publications);
• the 1997 World Development Report (WDR) published by the World Bank;
• the Global Competitiveness Report (GCR) published annually by the World
Economic Forum (WEF); and
• the World Competitiveness Yearbook (WCY) published annually by the
International Institute for Management Development (IMD).
Corruption Perceptions Index (CPI)
Transparency International (TI) has published the CPI annually since 1995.21 As its name
suggests, the index provides data on perceptions of corruption in countries. It is a
composite index based on surveys of the corporate sectors in various countries. The most
recent edition, the 2007 CPI, was based on 14 surveys sourced from 12 independent
institutions, covering 180 countries. The institutions were:
• The Asian Development Bank (ADB);
• The African Development Bank (AFDB);
• The Bertelsmann Foundation (BF);
• Freedom House (FH);
• The Economist Intelligence Unit (EIU);
• Global Insight (GI);
• The Institute for Management Development, Lausanne (IMD);
• The Political and Economic Risk Consultancy, Hong Kong (PERC);
• The World Economic Forum (WEF);
• The World Bank;
• Merchant International Group (MIG); and
21 TI also published a Bribe Payers Index in 1999 and 2002, but this index is rarely used in the literature. It is based upon surveys conducted in only 15 countries which measure respondents’ perceptions about the propensity for foreign companies to pay bribes in those countries. These perceptions are then used as a measure of corruption in the host countries of the foreign companies.
88
• United Nations Economic Commission for Africa (UNECA).
According to TI, the sources provided by the institutions listed above were selected after
meeting certain criteria. Primarily, the sources needed to provide a ranking of nations
which is only possible if the same methodology is used in each country surveyed. Further,
the sources needed to measure corruption on its own, without being interlaced with other
related issues such as political instability or nationalism (TI, 2007). For this reason, the
‘Corruption in Government’ index from the International Country Risk Guide (ICRG) was
not included in the CPI. In its 2003 edition of the CPI, TI argued that the ICRG index does
not measure corruption, but rather the political risk involved in corruption. Interestingly, TI
claimed that this can be misleading since corruption only leads to political instability if it is
not tolerated (TI, 2003).
In the 2007 edition of the CPI, data was extracted from the sources for the two years
preceding 2007 when available. These were averaged to “reduce abrupt variations in
scoring that might arise due to random effects” (TI, 2007, p.3). As this is done for each
annual edition, year-to-year comparisons are still possible though TI points out that
methodologies may change each year, which could affect a country’s score (2007).
Consistent with the literature (Bardhan, 1997), all 12 sources defined corruption as the
misuse of public power for private benefit. Some sources distributed surveys to the
corporate sectors in the countries, while others relied upon their own panels of experts to
make assessments about corruption levels. Specifically:
• the ADB, AFDB and World Bank issued surveys asking about the prevalence of
ineffective audits, conflicts of interest, policies being biased towards narrow
interests, policies distorted by corruption, and public resources diverted to private
gain;
• the BF asked its local correspondents to prepare country reports and quantitatively
assess the enforcement of corruption and the effectiveness of anti-corruption
measures;
• the IMD issued a survey asking elite businessmen whether bribing and corruption
prevail or do not prevail in the economy;
89
• the PERC asked expatriate businessmen how bad they considered corruption to be
in the country they work as well as in their home country;
• the EIU defines corruption as the misuse of public office for personal (or party
political) financial gain and asks its panel of experts to assess the incidence of
corruption;
• MIG asked its correspondents to assess the level of corruption in the form of
bribery;
• FH’s panel of experts assessed factors including the implementation of
anticorruption initiatives, public perceptions of corruption, laws on financial
disclosure and conflict of interest, protections for whistleblowers, and the media’s
coverage of corruption;
• GI assessed the likelihood of encountering corrupt officials and other such groups;
• UNECA asked its panel of experts to assess the level of corruption in areas such as
the legislature, judiciary, the executive level, and tax collection in each country; and
• the WEF, in its Global Competitiveness Report, asked respondents to what extent
their firms made undocumented extra payments or bribes connected with exports
and imports; public utilities; annual tax payments; public contracts; loan
applications; influencing laws and policies to favour selected business interests; and
getting favourable judicial decisions (TI, 2007)
A key point that TI emphasises is that the questions listed above measure only the degree of
corruption, in line with the aims of the CPI. TI acknowledges that this ignores the important
distinction between nepotism and corruption in the form of monetary transfers, but argues
that both are merely forms of the same ‘corruption’ phenomenon (TI, 2007).
The CPI is created using the ranks of countries according to each source. This data is then
standardised using matching percentiles. Common sub-samples from a new source and the
previous year’s CPI, and the largest value in the CPI become the standardised value for the
country ranked best by the new source. For example, assume a source ranks only five
countries in the order UK (4.2), Singapore (3.9), China (2.8), Malaysia (2.7) and India
(2.4). In the 2004 CPI these countries obtained the scores 8.6, 9.4, 3.2, 5.1 and 2.9,
respectively. Matching percentiles would now assign UK the best score of 9.4, Singapore
90
second best with 8.6, and so on. This method is preferred because all standardised scores
are within a range of 0-10, which is consistent with the range for each source (TI, 2007).
The standard deviation of the index at this point will be much smaller than that of previous
CPIs, and this trend will continue unless a further adjustment is made. A beta-
transformation is made to preserve the standard deviation of the previous year’s CPI while
still keeping the scores between 0 and 10. Each score, X, is transformed according to the
following function:
1
10 × ∫ (X/10)α-1 (1-X/10)β-1 dX (5.1) 0
The parameters α and β must be found such that the resultant mean and standard deviation
is as desired. Once this is achieved, the CPI is complete. To check for validity, correlations
are generated between each of the sources used in the CPI. In 2003, the average Pearson
correlation was 0.87 and the corresponding Kendall’s rank correlation was 0.72 (TI, 2003).
Table 5.1 shows a selection of the 2007 CPI rankings.
The CPI’s biggest selling point is that it is an index of indices. The fact that the CPI is
based on several sources helps to give credibility to its results. For example, if country X
received a high corruption rating from only one source, and a clean rating from the
remaining nine sources, it would not be featured in the high end of the CPI rankings. But if
that particular source was used independently, one might be tempted to believe that country
X was indeed corrupt. These sorts of biases disappear, the more sources are used to ensure
consistency in the ratings.
It is this feature that makes the CPI one of the most popular measures of corruption in the
literature (see Table 5.2). However, the trouble with the CPI is that its definition of
corruption is limited to the payment of bribes to bureaucrats. Although this is the way
corruption is defined in the literature, it fails to pick up the alternative dimension of
corruption highlighted by this study, namely the rent-seeking that arises out of patron-client
networks that exist between the government and the private sector in many countries.

International Country Risk Guide (ICRG)
The ICRG was first created in 1980 by the editors of International Reports, a weekly
newsletter on international finance and economics. In 1992, ICRG moved to the Political
Risk Services Group, a ratings firm based in the US (Political Risk Services Inc., 2004).
The ICRG model develops composite risk ratings based on risk factors and their bearing on
business or investments. The model is based on a set of 22 components grouped into three
major categories of risk: political, financial, and economic. For each country, the model
provides a rating for each component in the form of a score, similar to the process used by
TI.
92
The ‘political risk’ category contains a component labelled ‘corruption’. The ICRG (2004,
p.5) states that “the most common form of corruption met directly by business is financial
corruption in the form of demands for special payments and bribes connected with import
and export licenses, exchange controls, tax assessments, police protection, or loans”. The
measure of ‘corruption’ is said to be “more concerned with actual or potential corruption in
the form of excessive patronage, nepotism, job reservations, ‘favor-for-favors’, secret party
funding, and suspiciously close ties between politics and business” though no information
is given on exactly how this is measured, other than a statement that results are collected
through the completion of surveys (p.5).
However, according to Howell (2001), the corruption ratings by the ICRG are strongly
linked to government stability and accountability. Howell (2001, p.26) states that the
“highest risk ratings tend to signify an accountable democracy whose government has been
in office for less than five years” and the lowest ratings are “usually given to one-party
states and autarchies (sic)”. This is consistent with TI’s claim that the ICRG ratings are
political in nature. Another problem with the ICRG is its scale. Until 2000, the scores were
all integers between 0 and 6 (6 indicating the absence of corruption). Such a narrow range
meant that a lot of countries remained at the same level, even though the corruption level
may have changed. In other words, it would have to take a significant change in corruption
to make a country move by one point on the scale, since there were only seven points in
total. In 2001 the points were doubled when half-points (0.5) were introduced. However,
this did little to alleviate the problem.
Another problem is the rankings under the ICRG. For example, in 1996, the US, the UK,
France and Singapore were all at the same level as Nicaragua, Namibia, Libya,
Mozambique and Guatemala, and were deemed more corrupt than Costa Rica, Cyprus and
South Africa. This makes the ICRG less marketable as an accurate measure of corruption,
however it is still as popular as the CPI in the literature only because it provides data over a
much longer timeframe (at least fifteen years), while the CPI was only introduced in 1995.
93
Business International (BI)
The BI index is no longer in existence and has been incorporated into the Economist
Intelligence Unit’s publications on risk. Mauro (1995) provides an insight into this index,
which covered 56 country risk factors for 68 countries during 1980-1983. In particular,
Mauro (1995, p.684) focused on nine indicators, namely:
• Political change (institutional) – possibility that the institutional framework will be
changed within the forecast period by elections or other means;
• Political stability (social) – conduct of political activity, both organised and
individual, and the degree to which the orderly political process tends to disintegrate
or become violent;
• Probability of opposition group takeover – likelihood that the opposition will come
to power during the forecast period;
• Stability of labour – degree to which labour represents possible disruption for
manufacturing and other business activity;
• Relationship with neighbouring countries – this includes political, economic and
commercial relations with neighbours that may affect companies doing business in
the country;
• Terrorism – the degree to which individuals and businesses are subject to acts of
terrorism;
• Legal system and judiciary – efficiency and integrity of the legal environment as it
affects business, particularly foreign firms;
• Bureaucracy and red tape – the regulatory environment foreign firms must face
when seeking approvals and permits and the degree to which it represents an
obstacle to business;
• Corruption – the degree to which business transactions involve corruption or
questionable payments.
Mauro (1995, p.684) selects these indicators because they are assessed independently of
macroeconomic variables, and also because “they refer to the interests of any firm
operating in the country in question, rather than specifically to foreign-owned multinational
companies”. Mauro then takes the simple average of the scores for each indicator for the
94
period 1980-83. A high score corresponds to a better institutional quality. In his 1997 paper
Mauro used the same BI index but also included the ICRG index, averaged for the period
1982-95.
1997 World Development Report (WDR)
The 1997 World Development Report was published by the World Bank and included an
Executive Survey that sought to capture private sector perceptions of institutional
uncertainty. The main part of the survey consisted of five sections, as follows:
• the predictability of laws and policies – uncertainties created by the legislative
process;
• political instability and security of property – uncertainty arising from transfer of
government power;
• government-business interface – government obstacles to doing business;
• law enforcement and bureaucratic red tape – degree of corruption and whether it is
a predictable transaction cost or an uncertainty; and,
• government efficiency in providing services – degree of efficiency in the
government provision of health care, utilities, roads, etc (World Bank, 1997).
Countries were then ranked based on their responses to the survey questions. Five of the
eight questions that explored corruption under the ‘law enforcement and bureaucratic red
tape’ section were in the form of statements, and respondents were meant to indicate the
degree to which the statement was true by using a scale of 1 to 6, with 1 indicating the
statement was always true, while a 6 meant that the statement was never true. The questions
were as follows:
Question 14: It is common for firms in my line of business to have to pay some
irregular “additional payments” to get things done.
Question 15: Firms in my line of business usually know in advance about how
much this ”additional payment” is.
95
Question 16: Even if a firm has to make an “additional payment” it always has to
fear that it will be asked for more, e.g. by another official.
Question 17: If a firm pays the required ”additional payment” the service is
usually also delivered as agreed.
Question 18: If a government agent acts against the rules I can usually go to
another official or to his superior and get the correct treatment.
In addition to the survey, a credibility index was also designed to measure the reliability of
the survey responses. The index was the simple mean of the average answers to five
‘subindicators’ which was then normalised such that the index for high-income OECD
countries was set to one. The first subindicator measured the predictability of rulemaking,
or the extent to which entrepreneurs have to cope with unexpected changes in rules of
policies. The second assessed the subjective perception of political instability, or whether
government changes were signs of dramatic policy ‘surprises’. A third subindicator dealt
with security of persons and property, to see whether entrepreneurs had confidence in the
security prowess of the authorities. Predictability of judicial enforcement was captured by
the fourth subindicator, measuring the degree of uncertainty arising out of arbitrary
enforcement of rules by the judiciary. And the final subindicator measured corruption,
defined as the practice of entrepreneurs having to make irregular additional payments to get
things done (World Bank, 1997).
Ahmad (2003) relied upon the WDR for three indices measuring the perception of
corruption. Two of the indices were based on the responses to questions 14 and 16 above.
However, Ahmad (2003, p.10) noted that these results may be “misleading as these two
indices reflect the perception of the same group of respondents”. Therefore, Ahmad also
used the CPI. However, Ahmad also used the responses to Question 12n, which fell under
the section on ‘government-business interface’. The question asked respondents to judge
how problematic corruption was for doing business, again using a scale of 1 to 6. The
WDR index was only published once (i.e., for one year) and therefore is severely limited in
its scope.
96
Global Competitiveness Report (GCR)
The Global Competitiveness Report is produced jointly by the World Economic Forum and
the Harvard Institute for International Development on an annual basis. The Report is also
based on surveys. In the 2003-04 edition, respondents were asked the following questions
on corruption:
Question 7.01 How commonly are bribes paid in connection with import and export
permits?
Question 7.02 How commonly are bribes paid when getting connected with public
utilities?
Question 7.03 How commonly are bribes paid in connection with annual tax
payments?
Respondents were required to provide a score on a scale of one to seven. These scores were
then combined to produce the corruption index (WEF, 2004). Wei and Wu (2001)
combined both the WDR and the GCR for their measure of corruption. Johnson et al.
(1998) also used the GCR, but used data from eight different questions covering tax burden
as reported by the firm; regulatory burden; government intervention in the enterprise
sector; regulatory discretion and enforcement; extent of bribery payments; police
effectiveness; and labour regulations. Unfortunately, editions of the GCR prior to 2000 are
no longer in print and therefore this source is unable to be used in this study. Fortunately
though, the GCR data is subsumed in the CPI scores.
World Competitiveness Yearbook (WCY)
The WCY is published on an annual basis by the International Institute for Management
Development (IMD), providing a measure of the competitiveness of nations. Some 320
competitiveness criteria were used in the 2003 edition to rank 59 countries and regional
economies (Rosselet-McCauley, 2003). In addition to compiling statistics, an executive
survey is also conducted every year to measure perceptions of competitiveness. According
to IMD, the survey “is an in-depth 116-point questionnaire sent to executives in top- and
middle management in all of the economies” ranked in the Yearbook (Rosselet-McCauley,
97
2003, p.3). The aim of the survey is to quantify issues that cannot be easily measured, one
of which is ‘corruption’. Corruption falls under the criteria of “Institutional Framework”,
which in turn is part of the “Government Efficiency” competitiveness factor.22 IMD states
that the surveys are sent to “executives who represent a cross-section of the business
community in each country or region” and are asked to “evaluate the present and expected
competitiveness conditions of the economy in which they work and have resided during the
past year, drawing from the wealth of their international experience, and thereby ensuring
that the evaluations portray an in-depth knowledge of their particular environment”
(Rosselet-McCauley, 2003, p.5). In 2003, 4,256 responses were received from the 59
economies surveyed (Rosselet-McCauley, 2003).
Alesina and Weder (1999, p.1128) refrained from using a single index or creating one,
preferring instead to use all available cross-country measures of corruption (including the
WCY), arguing that “[w]hile we would not trust 100 percent any specific index, we feel
more confident if a certain pattern of results is consistent for every measure of corruption”.
Alesina and Weder used seven indicators of corruption from six different sources, the first
of which is the ICRG. The second source is a survey conducted for the 1997 WDR, from
which two indicators are extracted measuring frequency of bribe-paying and the importance
of different obstacles to business. A third source of corruption data is from Standard and
Poor’s, and a fourth is the BI index. The last two sources are the WCY, and the CPI. Table
5.2 shows the extent to which each of the indices mentioned above is used in the literature.
Other Measures of Corruption
In some cases, corruption is measured without the use of the major indices. For instance,
Del Monte and Papagni (1997) measure corruption as the number of crimes committed
against the public administration per million employees. This data was sourced from the
national statistical bureau in Italy. Similarly, Depken and LaFountain (2004) measure
corruption as the number of federal public corruption convictions per 100,000 residents in a
particular state, sourced from the Public Integrity section of the US Department of Justice.
22 There are four competitiveness factors that are used to assess countries, namely economic performance; government efficiency; business efficiency; and infrastructure. Some 243 criteria fall under these factors, of which 116 are assessed through the Executive Survey.

Some studies have used other obscure measures of corruption in addition to the five major
indices. For example, Alesina and Weder (2002) also used data from Standard and Poor’s.
Emerson (2006) used data from the World Audit Organization’s World Democracy Audit
publication. Hwang (2002) drew on the Levine-Loayza-Beck (1999) dataset. Johnson et al.
(1999) also used the Impulse Exporter Bribery Index constructed from a survey of German
business people conducted in 1992-94 by Peter Neumann at Impulse (a German business
publication).
The World Bank (2004) released an index of Governance Indicators which measure six
dimensions of governance covering 199 countries and territories in 1996, 1998, 2000 and
2002. The data is extracted from 25 sources constructed by 18 different organisations. In
99
this sense only, the index is similar to the CPI in that it is a composite index. One of the
dimensions of governance is labelled as “Control of Corruption”, drawing on the individual
measures of corruption in the 25 data sources. But this corruption index (hitherto referred to
as the KKZ index) is in fact markedly different from the CPI, and in fact was intended to
supersede the CPI.23 Whereas the CPI sometimes used two and three years of data from the
same source and treated them as separate sources, the KKZ index only used data from one
year at a time. There are also significant differences in the way the countries’ scores are
generated (Kaufmann et al. 2003).
5.3 Correlation Between Indices
To determine whether there is any consistency in the approaches adopted in each index, the
correlation coefficients between selected pairs of indices were obtained. As a starting point,
a typical year before the 1997 financial crisis (namely, 1996) will be used for analysis as
that year is also the focus of empirical exercises in Chapter 8. Of the six major indices, only
the CPI, WDR, and WCY have data for 1996.24 The KKZ index was also available, but this
will be discussed later. A total of 22 countries appeared in all three indices. All scores were
converted to a common scale of 0 – 10, with 0 indicating extreme bribery or corruption, and
10 indicating zero bribery or corruption. The WDR scores were separated according to the
specific question that was asked. Only two questions were considered: Question 12n, which
asked respondents to rate the level of corruption; and Question 14, which asked respondents
to rate the level of bribery. When plotting these results against those of the CPI the results
are intriguing as shown in Figures 5.1 and 5.2. The correlation coefficient in both Figures is
0.87. However by looking at the graphs, one can see the striking difference between the
ratings under each of the WDR questions. None of the scores for question 14 are less than
4, so the data appears slightly skewed (Figure 5.2).
23 KKZ is an acronym for the surnames of the World Bank staff who first constructed this index: D. Kaufmann, A. Kraay and P. Zoido-Lobaton. 24 Although the WDR was published in 1997, the survey results were obtained in late 1996. The CPI and WCY survey results are always obtained in the same year of publication. To ensure consistency, the 1996 CPI and WCY data are used in conjunction with the WDR data.

In Figure 5.3, the two WDR indices are plotted against each other. The correlation
coefficient between the two WDR indices was 0.85. Interestingly, most of the countries
appear above the dashed line in the graph, which represents a low score for Question 12n,
and a high score for Question 14.25 This translates to a high level of corruption, but a low
level of bribery. This indicates that, at least in the minds of the respondents, there is a
substantial difference between bribery and corruption. The finding is also at odds with the
general definition of corruption in the literature, which, as shown in Chapter 2, implicitly
includes bribery. This inconsistency renders the WDR somewhat less appealing as an
accurate measure of corruption. However, it provides support for exploring alternative
dimensions of corruption, such as rent-seeking, in Chapter 8.
25 The line of best fit for Figure 4.3 has an intercept of 4.67, which is an indication of the skewness of the data.

The sample size between the CPI and the WCY only is 44 countries compared to the 28
between the CPI and WDR (with some overlapping countries). The latter is much smaller
because the WDR covers a very sparse range of countries – the only two Asian countries in
its sample are India and Malaysia. Figure 5.4 plots the CPI against the WCY for 1996. This
time the correlation coefficient is 0.97, implying a stronger relationship.
Figure 5.5 plots the relationship between the WCY and KKZ indices in 1996. The
correlation coefficient is 0.98, based on a sample of 46 countries, indicating an extremely
high level of consistency in their assessment of corruption levels. Given this strong
relationship, and the consistency in the scale, the two indices were averaged to provide a
single index for use in a cross-sectional model analysing the effect of corruption on growth.
Based on the average of the two indices, most of the East Asian members in the sample
have scores lower than the mean of 5.53. In fact, the average for East Asia is 4.42. When
Singapore is excluded (as an outlier with an average score of 9.14), the average falls to 3.89
indicating a high level of corruption.

5.4 Conclusion
This chapter has identified the major sources of corruption data used in the extant literature.
It has been established that the CPI and the ICRG index have been the most popular ones
(Table 5.2). Table 5.3 summarises the major indices.
Although the CPI is clearly superior to the ICRG index, the latter is popular because it was
introduced as early as 1980 while the CPI was only introduced in 1995. The BI index and
the WDR index all attempted to provide similar measures of corruption, however they were
only published occasionally and are now no longer in existence. The WDR index also
harboured an apparent inconsistency in its measurement of corruption. The GCR continues
to be published, however gaining access to issues prior to 2000 has not been successful as
they are no longer in print. The timeframe of this study’s empirical investigation for both
cross-sectional (1996) and panel data analysis (1984-2003) renders the GCR less worthy of
inclusion, however it should be noted that the GCR is one of the sources in the CPI so it
will still make a contribution. The next chapter will provide a cross-sectional analysis of the
103
effect of corruption on economic growth based on the relevant data for the year 1996 (the
year immediately preceding the Asian Financial Crisis).

CHAPTER 6
CORRUPTION AND GROWTH: A CROSS-COUNTRY STUDY
“Anti-corruption and building a clean government are an important
strategic mission…We cannot slack off for one moment…If a ruling party
cannot maintain flesh-and-blood ties with the mass people, if it loses the
people’s support, it will lose its vitality.”
- Chinese President Hu Jintao26.
6.1 Introduction
As explained in Chapter 3, there exists a substantial amount of literature that seeks to
investigate the connection between corruption and economic growth. The greatest
limitation to these studies is the way in which they measured corruption. In Chapter 5 the
most popular measures were reviewed and some alternative methods were proposed. The
purpose of this chapter is to explore the effect of corruption on economic growth in East
Asia before the 1997 Asian Financial Crisis. By the definition of corruption established in
Chapter 2, how corrupt are the East Asian countries? How do they measure up against the
rest of the world? Did corruption contribute to the spectacular economic growth that was
achieved by those countries prior to 1997? This chapter seeks to shed some light on these
questions.
The chapter begins by presenting the methodology for a cross-sectional model to analyse
the effect of corruption on growth. The derivation of this model will be based on previous
studies of corruption and growth. This will be followed by a summary of the data required
and its means of collection, including the corruption variable. Finally, the results of the
application of the model to the data will be presented and discussed accordingly.

6.2 Developing A Corruption-Growth Model
After settling upon a means of measuring corruption, the corruption variable together with a
number of control variables was included in a model with the rate of economic growth as
the dependent variable. This section describes examples of the control variables used in the
extant literature. The examples are pertinent as they form the framework upon which the
model in the present study was constructed.
Mauro (1997) performed a regression between the 1960-85 average rate of annual growth
in GDP per capita and the corruption level in over 100 countries. Population growth, the
level of secondary education and an initial level of GDP were used as control variables and
drawn from the Barro (1991) dataset. This data was sourced from the IMF’s Government
Finance Statistics (GFS) and the United Nations Educational Scientific and Cultural
Organization (UNESCO). The data for industrial countries was added to the Devarajan,
Swaroop and Zou (1993) dataset of developing countries to increase the sample to 95
countries sourced from the GFS in 1985. Mauro also employed three instrumental variables
in his study to address potential endogeneity bias.27
Ali and Isse (2003) employed a regression model similar to Mauro (1997). They also
included a number of other variables in their study. An economic freedom index was taken
from Gwartney and Lawson (1997) for more than 100 countries, measuring “the extent to
which economic agents are free to use the market mechanism for the allocation of resources
and the extent to which property rights are protected” (Ali and Isse, 2003, p.462). Ethnicity
was used because “the domination of one ethnic group in the political arena of an economy
creates differential access to power” (p.463). Corruption was thus used to level the political
and economic playing field. Further, Ali and Isse argued that corrupt bureaucrats would
favour their family first, followed by their ethnic group, and finally their country. This
suggested that ethnically fragmented societies were more likely to be corrupt. Mauro
(1997) incorporated a similar variable in his study, so it was no surprise that Ali and Isse
took the index from an earlier study by Mauro in 1995, as well as from Easterly and Levine
27 These variables were related to ethnolinguistic fractionalisation, which measures the probability that two randomly selected persons from a given country will not belong to the same ethnolinguistic group (Ali and Isse, 2003).
106
(1997). A political freedom index taken from Freedom House was also used because Ali
and Isse suggest that the more free a country’s media is, the more transparent its
government will be forced to become. A rule of law index (from Political Risk Services) for
the 1982-1990 period was incorporated into the study, measuring soundness of political
institutions, strength of judicial systems, and orderly successions of power. Strong rankings
on these criteria are deemed by Ali and Isse (2003) to make a country less susceptible to
corruption. The secondary school enrolment rate in 1975 was also used, though Ali and
Isse’s contention here is that a higher level of education will make public servants more
aware of what behaviour is deemed to be corrupt, and will discourage them from engaging
in this behaviour out of loyalty to the nation (stemming from increased national pride). In
other words, secondary education is seen as an explanator of corruption rather than
economic growth. The centralisation of a country’s government power was also used, but
as a binary variable instead of an index, because centralisation can lead to higher corruption
through increased collusion amongst bureaucrats, but so too can decentralisation through
increased opportunities provided at each level of government. Finally, government
expenditure as a share of GDP was included on the basis that “the larger the size and scope
of the public sector, the greater the likelihood of corrupt behaviour” (p.463). The present
study differs from Ali and Isse (2003) in several ways. The corruption measure employed
in the present study is wider as it is based on five corruption indices, compared to two
indices used in Ali and Isse (2003). The time period analysed in the present study is also
longer than that of Ali and Isse (2003), and whilst the latter found corruption to be
negatively associated with economic growth, the present study reveals some evidence to the
contrary as will be seen later.
Li et al. (2000) used a slightly different model, focusing on growth in different time
periods: 1980-1984; 1985-1989; and 1990-1992. Lagged values for schooling and financial
development were used to account for the endogeneity problem. They used five-year
averages for all the variables in the model. The control variables used were initial level of
GDP, primary years of schooling, financial development (money supply M2 over GDP),
openness (imports over GDP), terms-of-trade shocks (difference of changes in export price
and changes in import price), black market premium, government spending (as a fraction of
GDP), average arable land, the urbanisation ratio, the population growth rate and the initial
distribution of asset as measured by the initial land Gini coefficient. Most of the data was
107
taken from World Bank national accounts and from Summers and Heston (1994). The black
market premium data was taken from Barro and Lee (1994). Primary years of schooling
data was extracted from Nehru et al. (1995).
A slightly more complex model was employed by Rahman et al. (2000) to investigate the
impact of corruption on economic growth. Specifically, the authors augmented Mauro’s
model by including statistically significant regional dummies, using the ICRG corruption
index for 1991-1997 as it is more recent than the BI index, and condensed the length of the
sample period to 1990-1997 instead of Mauro’s 26 year period from 1960-1985. Further,
the authors “demonstrate the sensitivity of the effect of corruption in the presence of
various other policy, geographic and demographic variables that have been widely used in
empirical growth literature” (p.7). The corruption data was provided on a monthly basis for
130 countries, and Rahman et al. (2000) averaged this to obtain annual values for the 1991-
1997 period. Data for schooling, area and distance to the capitals of the world’s 20 major
exporters (weighted by values of bilateral imports) was taken from Barro and Lee (1994),
while the remaining data was extracted from the World Bank’s SIMA database. Control
variables included initial quantity of human capital which was proxied by the gross
secondary school enrolment rate in 1985. Initial quality of human capital was also used, and
measured by the pupil/teacher ratio in secondary school in 1980. Initial GDP was taken as
the log of GDP per capita in 1985.
An interesting variation of the standard corruption-growth model appears in Mendez and
Sepulveda (2001). The conditioning set of variables include measures of initial human
capital and GDP, investment and government shares of GDP, population growth rate,
political instability and regional dummies. However Mendez and Sepulveda included a
quadratic corruption term in the equation, allowing the model to capture the growth
maximising level of corruption which is ignored in a linear model.
Given the above sample of regression models, the framework for the model to be used in
the present study can now be established. As shown above, the empirical literature
investigating the link between corruption and economic growth relies upon regression
analysis, and this study will follow suit. Typically, regression involves economic growth
(measured by annual percentage change in real GDP) as the dependent variable. Corruption
108
is introduced as an independent variable, along with other control variables. The regression
model for this chapter, based on cross-sectional data in 1996, is therefore as follows:
k
уi = α + βCi + ∑ λjZij + μi (6.1)
j=1
where у = rate of economic growth
C = corruption index
Z = set of control variables
μ = error term
α, β and λ are unknown parameters to be estimated
6.3 Data Issues
Economic Growth Indicator
The measure of growth in all studies is based upon GDP, typically expressed as an annual
percentage change. GDP growth is used in Mendez and Sepulveda (2001), Li et al. (2000),
Ali and Isse (2003), Svendsen (2003), and Mauro (1995), to name a few. Rahman et al.
(2000) used GNP instead of GDP because the focus was on the influence of foreign direct
investment on growth, so the growth variable needed to account for foreign production. In
most cases, real GDP per capita is used to factor in the growth in population (Mauro, 1995;
Ali and Isse, 2003; Svendsen, 2003; Tanzi and Davoodi, 1997), however this study will
simply include population growth as an independent variable as it allows the study to
identify and isolate the individual effect of population growth on economic growth. GDP
data in the literature was sourced mostly from the IMF, World Bank, or Heston et al.
(various years). Economic growth in this study will be represented by the variable
‘GROWTH’, and the relevant data was extracted from the World Bank’s World
Development Indicators (2005) database.
Corruption Variable
The corruption variable differs somewhat considerably between studies. Mauro’s (1997)
corruption index was a simple average of the ICRG and BI corruption indices when both
were available, and the ICRG alone for all other times. The ICRG data was the average
109
from 1982-1995 for 100 countries, while the BI data consisted of the 1980-1983 average
for 67 countries.
Ali and Isse (2003) analysed corruption in two different time periods: the 1980s and the
1990s. Corruption in the 1980s was based on information collected from Political Risk
Services, from 1982-1990. Li et al. (2000) used the same source in their study, but over the
time period 1982-1994. Corruption in the 1990s was based on Transparency International’s
CPI from 1995-1999. Ali and Isse reversed the rankings of both indices (such that a lower
value means lower corruption) and then compressed the scale to a range of 0 to 1.
Mendez and Sepulveda (2001) used the ICRG corruption index from Political Risk
Services. Since this index is not available before 1982, the authors used the average of the
index for 1982-1992 as an approximation for the corruption level present during the entire
period. Further, they assumed that the same levels of corruption held for 1960-1984. This
was based on a 0.86 correlation coefficient for the Transparency International corruption
index from 1980-1996.
In the current study, the World Bank’s KKZ index will initially be used as the measure of
corruption in the cross-sectional regression model. Alternate indices will then be used as
part of a sensitivity analysis. In all regression results however, the corruption variable will
be represented as ‘CORRUPT’.
Control Variables
One of the most popular control variables used as a determinant of economic growth is
education, and this is typically represented by levels of secondary enrolment (Mauro, 1997;
Ali and Isse, 2003). However, some studies have used primary years of schooling (Li et al.,
2000), and others have used both primary and secondary school enrolment (Mendez and
Sepulveda, 2001). One would argue that education improves the quality of a country’s
human capital, which will then feed into productivity and ultimately yield growth in an
economy. In the following analysis, secondary education (measured as the number of
students enrolled in secondary education as a percent of official population in
corresponding age group) will be represented by the variable ‘SECENROL’. Population
growth is another standard control variable, used by nearly every study either as an
110
independent variable or subsumed into a per capita GDP measure of economic growth. As
population increases, one would expect an increase in consumption and the size of the
labour force, both of which would increase demand and output in an economy. Population
growth (measured as the annual percentage change in population) in this study will be
referred to as ‘POPRATE’ in the discussion of results. Gross secondary enrolment rates and
population growth rates were both extracted from the World Bank’s World Development
Indicators database (2005).
Furthermore, the gross fixed capital formation of countries will also be included as another
control variable. According to the World Bank (2005), gross fixed capital formation
consists of outlays on additions to the fixed assets of the economy, which include land
improvements (fences, ditches, drains); plant, machinery, and equipment purchases; and the
construction of roads, railways, schools, offices, hospitals, private residential dwellings,
and commercial and industrial buildings. One would therefore expect the growth rate of
gross fixed capital formation (represented by the variable ‘GFCFRATE’) to be related to
economic growth.
In addition, the following control variables will also be used in the current study:
• LNGDP85 is the natural logarithm of GDP in 1985 used to represent initial income,
which is expected to have a negative relationship with growth as the higher the
initial level of GDP, the less scope there is for ‘catch-up’ or improvement upon this
level.
• EXPRATE represents the annual growth rate of exports of goods and services. This
includes the value of all goods and other market services provided to the world such
as merchandise, freight, insurance, travel, and other nonfactor services. Factor and
property income such as investment income, interest, and labor income, is excluded.
It is expected that if the growth rate in exports rises, this should lead to an increase
in economic growth due to increased production.
• EXPGDP expresses the annual value of exports (as defined above) as a percentage
of GDP. An increase in this variable would also tend to raise economic growth due
to increased production.
111
• MKTCAP represents the total market capitalisation of listed domestic companies as
a proportion of GDP. Market capitalisation is calculated as the share price times the
number of shares outstanding. Listed domestic companies are the number of
domestically incorporated companies listed on the country’s stock exchanges at the
end of the year. One may expect that if firms increase in value and the share price
rises, then the value of their business is rising and this contributes to increased GDP
and thus economic growth.
• REALINT is the real interest rate prevailing in a country, measured as the deposit
interest rate less the rate of inflation measured by the GDP deflator. If interest rates
rise, this would raise the cost of borrowing and would tend to impede production by
firms, so GDP would possibly fall as rates continue to rise.
• GVEXGDP represents annual general government final consumption expenditure as
a proportion of GDP. This includes all current expenditures for purchases of goods
and services by all levels of government, excluding most government enterprises. It
also includes capital expenditure on national defence and security. Increased
government spending is likely to increase GDP through the multiplier effect.
• HITECHEX: expresses the proportion of manufactured exports that are ‘high-
technology exports’. These are deemed to be goods produced by industries (based
on U.S. industries) that rank in the top 10 according to research and development
expenditures. Manufactured exports are the commodities such as chemicals and
related products, basic manufactures, manufactured articles, and machinery and
transport equipment. As exports become more hi-tech, one might expect production
capabilities to expand and grow, and thus the value of GDP will rise to reflect the
greater value of exports28.
In the regression model, the question of endogeneity needs to be addressed. Ali and Isse
(2003) and Mauro (1997) employed instrumental variables to tackle this problem. Li et al.
(2000) used lagged values of certain variables such as the secondary enrolment variable.
This study will follow the Li et al. (2000) procedure of using one-year lags.
28 Some control variables have been omitted from the present study’s analysis due to lack of reliable data.

As the focus of this study is the connection between growth and corruption in pre-1997
East Asia, 1996 data was collected and applied to the regression model outlined in the
previous section. To begin with, the World Bank’s KKZ index was used as a measure of
corruption. This covered a total of 151 countries and the corruption scores were
standardised with a mean of zero and a standard deviation of 1. In this study, 5 was added
to each score to raise the mean to 5 whilst retaining the standard deviation. This removed
the issue of negative scores. Figure 6.1 illustrates the general relationship between
corruption and economic growth in 1996. It is clear from Figure 6.1 that Tajikistan and
Suriname are outliers in the sample, so they were excluded from the analysis. Taiwan was
also excluded due to limited data availability. Economic growth was not available for a
further seven countries, so this left a sample of 141 countries.29

6.4 Estimation Results
Table 6.1 provides some descriptive statistics for the variables in this analysis (corruption;
gross fixed capital formation growth rate; population growth rate; gross secondary
enrolment rate; exports as a proportion of GDP; exports growth rate; market capitalisation
as a proportion of GDP; real interest rate; government expenditure as a proportion of GDP;
and high-technology exports as a proportion of manufactured exports). Table 6.2 reveals
the correlation matrix for these variables. There appear to be no instances of
multicollinearity as no correlations are 0.7 or greater. Regression results are outlined in
Table 6.330.

*Significant at 5% level. **Significant at 1% level.
In Table 6.3, all variables were included in Model 1 and the least significant control
variable (excluding corruption) was removed in a stepwise technique until only significant
variables remained. This occurred in Model 9, which identified four control variables to be
significant in the presence of corruption. The corruption variable itself was not significant
at the 5% level. Its coefficient was positive, and given that a low value in the KKZ index
reflects high corruption, this indicated a negative (though statistically insignificant)
relationship with economic growth. Note that the sample size increases each time a variable
is omitted. This is due to the gaps that exist in the data. Based on the preceding analysis, it
appears that when using the KKZ index as a measure of corruption there appears to be no
significant relationship between corruption and economic growth. But could this be due to
the KKZ index itself? In other words, would other corruption indices have yielded different
results? Table 6.4 below shows the results of the corruption-growth model based on
alternate measures of corruption, i.e. the ICRG, CPI and WCY indices. Only the final
models are reported after following the stepwise elimination technique. For the complete
tables, refer to the appendix to this chapter.
Table 6.4 shows that when using the WCY index and the CPI, there does not appear to be a
significant relationship between corruption and economic growth. However, when using the
ICRG index the corruption coefficient is negative and significant at the 5% level. The
reverse scale of the ICRG index implies that corruption has a positive effect on economic
growth. Specifically, for every unit decrease in the ICRG index (reflecting increased
corruption) economic growth rises by 0.565 percentage points. However the R2 is
extremely low at 3%. Having used single indices, the next step was to combine pairs of
indices, building on the analysis in Section 5.4 of Chapter 5. In creating the new composite
indices, each index was standardised and 5 was added to each score. This yielded indices
with a standard deviation of 1 and a mean of 5. The simple average of each pair of indices
then constituted a new composite index. For some of these pairings, there were not many
common countries so only the largest samples were used. Table 6.5 shows the results using
each of three composite indices. Once again, only results from the final models are reported
and full tables are in the appendix to this chapter.

As with Table 6.4, the results in Table 6.5 are mixed. Only the model using the KKZ-ICRG
index reveals that corruption is significant at the 5% level. Consistent with the results in
Table 6.4, the coefficient is negative, implying that an increase in the index value
(reflecting decreased corruption) leads to an increase in economic growth. The R2 is
extremely low at 4%, which is also consistent with Table 6.4. So far there appears to be
some evidence to suggest that corruption is positively related to economic growth. At the
same time however, the explanatory power of the model is too low to lend any credibility to
this evidence.

6.5 Endogeneity
To control for endogeneity issues, a series of lagged control variables were introduced into
all of the models above. These are as follows:
• GFCFRATE1 is the one-year lag of the annual rate of growth in gross fixed capital
formation, and is included because economic growth could potentially provide for
an increase in the investment in fixed capital in the following year.
• POPRATE1 represents the one-year lag of the annual growth rate in the population
growth rate. It is sometimes argued that economic growth may lead to an increase in
the population growth rate through the provision of better services (e.g. health,
education etc).
120
• SECENROL1 is the one-year lag of the gross secondary enrolment rate. As
mentioned earlier, the provision of better education services resulting from growth
could potentially lead to an increase in secondary enrolment.
• EXPRATE1 and EXPGDP1 correspond to the one-year lagged growth rate of
exports and the one-year lagged exports as a proportion of GDP respectively. It
could be argued that economic growth could lead to an increased production of
goods for foreign consumption, a capability financed by the increased revenue as a
result of higher economic growth.
• MKTCAP1 represents the one-year lag of total market capitalisation of listed
domestic companies as a proportion of GDP. One may expect that if firms increase
in value and the share price rises, then the value of their business is rising and this
contributes to increased GDP and thus economic growth. However, the economic
growth could then raise business confidence and spur more corporations to invest in
more projects, thus raising the share price and the value of market capitalisation.
• REALINT1 is the one-year lag of the real interest rate prevailing in a country. If
interest rates rise, this would raise the cost of borrowing and would tend to impede
the production by firms, so GDP would possibly fall as rates continue to rise.
However, falling growth rates could in turn lead to a fall in interest rates in an
attempt to lower borrowing costs and stimulate firms to borrow and invest, and
consumers to borrow and spend.
• GVEXGDP1 represents the one-year lag of annual general government final
consumption expenditure as a proportion of GDP. Increased government spending
is likely to increase GDP through the multiplier effect, but the increased GDP may
in turn increase the total revenue for the government and expand its budget,
allowing it to increase its expenditure.
• HITECHEX1 expresses the one year-lag of the proportion of manufactured exports
that are ‘high-technology exports’. As exports become more technologically
advanced, one might expect production capabilities to expand and grow, and thus
the value of GDP will rise to reflect the greater value of exports. As GDP grows,
firms and the government become richer and are able to invest more into research
and development, which could in turn lead to more high-technology exports.
121
A notable omission in the group of lagged variables is initial income (LNGDP85). The
reason for this is that the growth rate in later years cannot have any impact on income (or
anything) in earlier years. Table 6.6 shows the use of lagged variables in the presence of
corruption using the KKZ index as a measure of corruption. In the final model, only two of
the lagged variables are significant, namely the gross fixed capital formation rate and the
secondary enrolment rate. Interestingly, these are the one-year lags of the same two
variables that were significant in the final model of the analysis using the original control
variables (see Table 6.3 above). Their coefficients have the same sign indicating the same
direction of effect, except now the issue of endogeneity has been addressed.31 The R2 is
also higher at 20% compared to 14% in the previous model (though still rather low).
However corruption is still not found to be significant, as was the case in Table 6.3 earlier.
Table 6.7 shows a sensitivity analysis of these results in the presence of the alternate
corruption indices used earlier (both single and composite).
Table 6.7 reveals that the corruption variable is found to be significant in five of the
models, but the results are mixed. When using the ICRG and CPI Indices on their own, the
corruption coefficient is negative which implies a positive effect on economic growth. Both
coefficients are also statistically significant; at the 5% level when using the ICRG index,
and at the 1% level when using the CPI index. This represents a unique finding that
challenges the results found in many of the previous studies, and will be discussed further
in Section 6.6. However, when using the WCY and ICRG-WDR Indices the coefficient is
both positive and significant at the 5% level.
31 Granger causality tests would be required to establish causality, however such tests rely on the availability of longer time series data. As a second best alternative, one year lags are introduced to tackle the issue of endogeneity.

6.6 Corruption and Growth in East Asia
The preceding section has provided mixed results concerning the relationship between
corruption and economic growth using different measures of corruption. As this study
focuses on East Asian economies, some dummy variables are introduced to control for the
specific corruption-growth relationship in those economies. The rationale for this particular
analysis lies in the peculiar levels of corruption and growth that were seen in East Asia
prior to the 1997 Asian Financial Crisis, relative to the rest of the world. This can be seen in
Table 6.8 which does not include Taiwan due to data unavailability.
Table 6.8: Corruption and Economic Growth in East Asia, 1996

East Asia 6.9 0.48c 3.9 5.0 4.5 Rest of the world 4.3 -0.03 3.3 5.4 5.7 East Asia excl. Singapore 6.8 0.21 3.8 4.3 3.7 Rest of the world incl. Singapore 4.3 -0.01 3.3 5.5 5.8 Sample size for all regions 183 150 128 53 45
Notes: aAverage percentage growth rates. bFigures shown are averages. cUnlike the other indices, the KKZ index is not on a scale of 0 to 10, rather it is measured in standard deviation from the average so that 0.48 indicates the corruption level was 0.48 standard deviations above the mean corruption level.
Source: Compiled using data obtained from the World Bank (2002 and 2005), Political Risk Services Inc (1996), Transparency International (1996) and the International Institute for Management Development (1996).
In terms of economic growth, East Asia was far ahead of the rest of the world in 1996. Its
corresponding corruption level was also higher (given that a lower corruption index score
reflects a higher level of corruption) under the CPI and WCY indices. The distinction is not
as apparent under the KKZ and ICRG indices because these indices comprised much larger
samples of countries, which included many African, East European and South American
countries, all of whom suffer from considerable corruption. Table 6.8 also shows that when
Singapore is excluded from the East Asian sub-group, the difference in economic growth
between East Asia and the rest of the world contracts slightly whilst the corresponding gap
126
between corruption levels increases markedly. Though under the KKZ and ICRG indices
East Asia is still considered to be less corrupt than the rest of the world (due to the larger
sample), the gap narrows when Singapore is left out of East Asia. This reflects the
peculiarity of Singapore as an East Asian country that experienced ‘miraculous’ economic
growth prior to 1997 but was not plagued by corruption. Singapore consistently appears in
the top ten countries of all the corruption indices.
To test for the particular corruption-growth relationship in East Asia, a dummy variable
was introduced into the regression models. The dummy variable, Da, takes on a value of 1
for East Asian countries, and zero for all other countries. This is then multiplied by the
corruption score to investigate the interaction with corruption (Da*C). Both these dummy
variables are included in all the models reported (i.e., for each different measure of
corruption and in the presence of lagged variables) and the results are shown in Tables 6.9
and 6.10. Table 6.9 shows the inclusion of the dummy variable into the models without
controlling for endogeneity, while Table 6.10 reports the results after controlling for
endogeneity. Models involving the WDR index were excluded because the WDR sample
only contained one or two East Asian countries. Singapore was not given a value of 1 under
the dummy despite being an East Asian country, as it consistently appears as an almost
corruption-free country in all the indices (i.e., an outlier). Unfortunately, the dummy
variable and its interaction with corruption were not significant in any of the models. This
could be attributable to the fact that there were only seven East Asian countries in the
sample. This is an extremely small number and may not be statistically sufficient to yield a
significant result. To overcome this problem, in the next chapter panel data will be used.

6.7 Comparing Results with Existing Studies
The question now is how these results compare with findings from other empirical studies
analysing the relationship between corruption and economic growth. The studies presented
in Table 6.11 experimented with a variety of regression models, so in order to ensure
accurate comparisons with this study’s results, the statistics quoted are from the smallest
economic growth models (in terms of number of variables involved) that included
corruption, population growth and education as primary independent variables. Mauro
(1997) found a significant positive coefficient (i.e. a negative relationship) for his
corruption variable. Using a 2SLS regression on the same data, Mauro found that the
relationships are the same but the estimated coefficients are in fact larger, when the index
of ethnolinguistic fractionalisation is used as an instrumental variable to address possible
endogeneity bias. Multivariate regressions (both OLS and 2SLS) using other determinants
of economic growth produced similar results, and again the coefficients were larger under
the 2SLS method.
Ali and Isse (2003) found that corruption in the 1980s is strongly correlated with corruption
in the 1990s, which is interpreted as a sign that corruption was persistent over the years,
and the longer it persists the more endemic it becomes. Descriptive statistics for the
independent variables show that the mean and median of corruption in the 1990s were
higher than those for the 1980s. However, Ali and Isse pointed out that this could also be
explained by the fact that the data came from different organisations, and the survey
questions may have been quite different. Turning to the regression model, Ali and Isse
employed a few control variables, namely initial GDP, the population growth rate, and the
secondary school enrolment rate. When corruption in the 1980s is added to this model, the
coefficient is found to be significantly negative. It should be noted though that the R-
squared value for all but one of the regressions is not higher than 54%. Ali and Isse
conceded that corruption could be a function of economic growth, raising an endogeneity
problem. Running the regression using 2SLS with ethnolinguistic fractionalisation used as
an instrumental variable (similar to Mauro (1997)), Ali and Isse found that ethnolinguistic
fractionalisation is not correlated with economic growth, but has a significant negative
relationship with corruption. This suggests that higher corruption causes lower economic
growth.

Table 6.11: Regression Results from Existing Studies
131
*Significant at 5% level. **Significant at 1% level.
Li et al. (2000) found that the corruption variable is negative but not significant. However,
when a dummy variable for Asian countries is introduced, Li et al. (2000, p.18) found that
corruption had “a far less deleterious effect on growth in Asia than elsewhere”, though that
effect was still negative. In particular, the authors state that “during 1980-94 Asia did not
pay the price paid elsewhere for corruption; in other words, corruption may indeed have
acted as grease money in Asia during this period”. Adding further control variables to the
model reduces the significance of the corruption coefficient, but maintains its negative
effect. When adding government spending into the model, the variable itself is not
significant, but corruption has a greater effect on growth when government spending is
higher. Also, corruption reduces growth rates in countries where the distribution of land is
more unequal (as measured by the initial land Gini). However, the R-squared values for all
the growth-corruption regressions are never higher than 37%, indicating poor predictive
power.
Given these results, it is clear from Table 6.11 that none of the studies mentioned have
found corruption to have a positive impact on economic growth (statistically significant or
otherwise). As Rahman et al. (2000, p.12) concluded, “the focal variable, corruption, is
both economically and statistically significant”. This makes the findings in this chapter
unique. One reason why the result challenges the existing literature is the measure of
corruption in the present study. None of the studies in Table 6.11 used the World Bank’s
KKZ index.
Population growth was used in all studies, and yielded a consistent result. The coefficient is
negative in all studies, implying that slower population growth will result in higher
economic growth. However, the coefficient for the population growth rate was positive in
all the models in this chapter. This may be connected to the fact that economic growth in
the studies in Table 6.11 is measured on a per capita basis, unlike in the present study.
The results for education are mixed. Mauro (1995) and Mauro (1997) used secondary
enrolment rates in 1960, while Ali and Isse (2003) used the same in 1975. Rahman et al.
(2000) used gross secondary enrolment rate (same as the present study) in 1985, and also
used pupil/teacher ratio in secondary schools in 1985 (which was meant to measure the
quality of human capital, while the former measured the quantity of human capital). Li et
132
al. (2000) used primary years of schooling as a proxy for education. Mendez and Sepulveda
(2001) used total enrolment in both primary and secondary education in 1960 (but only the
secondary education coefficient is quoted in Table 6.11). Poirson (1998) used secondary
enrolment ratio as a proxy for education. In the present study, education was mostly found
to be insignificant, and this is consistent with findings by Poirson (1998), Li et al. (2000),
Rahman et al. (2000) and Ali and Isse (2003).
6.8 Conclusion
This chapter applied a simple regression using cross-sectional data to analyse the impact of
corruption on economic growth with particular focus on East Asia. Using data from 1996, a
typical year prior to the 1997 Asian Financial Crisis, a variety of corruption indices were
used in corruption-growth models. In most models, corruption was not found to be
significant. But in two particular models, one using the Political Risk Services Inc.’s ICRG
index and the other using the International Institute for Management Development’s WCY
index, corruption yielded a significant (5% level) negative coefficient, which implied that
there exists a significant positive relationship between corruption and economic growth. In
comparison with other studies, this represented a unique result as corruption was always
found to be negatively associated with economic growth. The inclusion of a dummy
variable representing East Asian countries did not produce any different results.
One limitation of these results is the measure of corruption. By virtue of its clandestine
nature, any measure of corruption is likely to be criticised for its accuracy, but this is not
something that can be avoided. Another limitation may have been the time period. Indeed,
this was a cross-sectional analysis of 141 countries but only one year was used. There may
have existed some peculiarities in that year that potentially distorted the results. Also, there
were not many East Asian countries in the sample. To address these issues, an analysis of
panel data is necessary. This will be the subject of the next chapter.

CHAPTER 7
CORRUPTION AND GROWTH II: A PANEL DATA ANALYSIS
“Wait and see how I do. If I am really bad, you can blame me.
Are all rich men bad?”
– Former Thai Prime Minister Thaksin Shinawatra.32
7.1 Introduction
In Chapter 6 the connection between corruption and economic growth was examined using
data of 1996, a typical year before the 1997 Asian Financial Crisis. The empirical analysis
presents evidence of a potentially positive relationship between the two variables
suggesting that high levels of corruption can indeed be synonymous with similar levels of
growth. This was true for all countries in the sample, not just East Asia. But as the analysis
was based on cross-sectional data, it begs the question of whether the results were only
particular to that 1996 sample. In this chapter, panel data will be used to investigate the
relationship between corruption and growth with special focus on East Asia, for 33
countries over the period 1984-2003. The chapter will begin with an analysis of corruption
data to be used in the model. This will be followed by an outline of the modified
corruption-growth model to allow for the use of panel data, and will go on to provide a
summary of the extra data required and its means of collection. The results will then be
presented and discussed accordingly.
7.2 Corruption Indicators
For the panel data model, corruption data was taken from the following three sources:
• the ICRG index for 1984-2001;
• the WCY index for 1991-2003; and
• the CPI for 1995-2003.
32 This was the Thai Prime Minister’s response to an accusation that he used his wealth to buy power, soon after an election victory (Anonymous, 1999, p.1).
156
Taiwan is excluded from the analysis due to lack of data leaving 33 countries in the
sample.33 Figure 7.1 illustrates the average corruption levels for East Asia and the rest of
the world using each of the three aforementioned indices, and it is clear that East Asia
consistently exhibits higher average corruption levels than other countries in the sample.
To estimate the corruption-growth model, the different indices need to be combined in
some manner to construct a single index of corruption. The most obvious technique would
be to take a simple average of the CPI, the WCY index and the ICRG index for the entire
sample period 1984-2003. However, due to the availability of each index in differing time
periods, not all years were an average of all three indices. For some years, like 1984, only
one index (ICRG) was available. The WCY and CPI values were on identical scales of 0 to
10, where 0 reflected extreme corruption, however the ICRG scale was 0 to 6 so its values
needed to be converted to fit the scale of the WCY and CPI data. This was achieved by
dividing each ICRG score by 6 and then multiplying it by 10. A sample of the corruption
data for East Asia using the resulting composite index is shown in Table 7.1. The data
reveals that overall the corruption level was rather high in the region, though Singapore and
Hong Kong seem to perform relatively well with the former recording extremely low levels
of corruption across all indices. Japan is close behind in the third place, followed by
Malaysia and the remaining countries. Indonesia almost always features last. The strong
performance of Singapore will prove to be significant in the empirical analysis later in the
chapter.
33 See Table A7.1 in the appendix to this chapter for the complete list of countries. Excluding Taiwan, only 33 countries appear in all three of the nominated corruption indices.

A graphical illustration of the corruption trends in East Asia and the rest of the sample
using the composite index for the entire period of 1984-2003 is shown in Figure 7.2, and
reveals that the average corruption score for the eight East Asian nations is well below that
of the remaining 25 countries, reflecting a higher level of corruption. However, the merging
of the three indices by taking a simple average may not necessarily be the best approach. A
potential problem evident in Figure 7.1 is that the three indices appear to show different
levels of corruption, on average, over the sample period. The ICRG index has an average
corruption level that appears higher than that of the CPI, which is in turn higher than that of
the WCY. This may explain the downward trend in the composite index in Figure 7.2.
To address this issue the corruption data for each index was standardised. The mean and
standard error required for the standardisation process were calculated using five different
techniques, namely,
• STD1 – calculating a mean for each year, then calculating the mean of those means
and the corresponding standard error;
• STD2 – calculating a mean for each country, then calculating the mean of those
means and the corresponding standard error,
• STD3 – calculating a mean and standard error for all corruption observations;
159
• STD4 – calculating a mean for each year and the corresponding standard error
(then standardising each country’s corruption observation by the mean and standard
error for that year only); and,
• STD5 – calculating a mean for each country and the corresponding standard error
(then standardising each country’s corruption observation by that country’s mean
and standard error).34

This procedure was repeated for each separate index so that there were a total of five
different datasets of corruption, with each dataset comprising the three standardised indices
(ICRG, WCY and CPI). Figures 7.3-7.7 plot the standardised corruption data.35 For STD4,
the average corruption for each year will necessarily be zero so charts for selected countries
are shown instead.
34 For all techniques, the ICRG scores were left in their original scale of 0-6. 35 Figures 7.3-7.7 are all products of the author’s own calculation based on data obtained from Transparency International (various years), the Institute for Management Development (various years), and Political Risk Services Inc.

Figures 7.3-7.6 reveal similar trends for all corruption indices regardless of which
standardisation technique is used, though the same is not easily discernable in Figure 7.7.
However, in Figures 7.3-7.6, the ICRG measure appears to provide a consistent pattern of
164
above average corruption scores (reflecting low corruption) prior to 1992/93, followed by a
significant deterioration in those scores (reflecting increasing levels of corruption). This
pattern appears to be independent of the standardisation technique employed, and indicates
that the ICRG index is suggesting that the countries in the present sample have on average
become increasingly corrupt in the last ten years of the sample period. Figure 7.8 plots the
average raw ICRG data for all countries over time and confirms this pattern. The diagram
shows that the average corruption rating for countries in the present sample was hovering
between 4.4 and 5.0 from 1984 to 1992, before plummeting to 3.6 in 2001. There is no
available information to suggest that the ICRG has deliberately assessed global corruption
levels to be rising in the last ten years of the sample period, so it is quite likely that this is
simply a pattern unique to the present sample.

Having created five standardised datasets of corruption (STD1 – STD5), a simple average
of the three indices was taken to provide a single composite index of corruption for each of
the five datasets. These five composite indices will later be used to test for sensitivity of
results based upon the original composite index, which was a simple average of the raw
165
corruption scores, in order to determine whether the simple average technique was reliable
and accurate.
Having already highlighted a significant difference in corruption levels between East Asia
and the rest of the countries in the sample it is worth considering whether a similar
relationship exists for economic growth. A comparison of economic growth between the
two groups, East Asia and the rest of the sample, is shown in Figure 7.9. The chart reveals
that between 1986 and 1996, East Asian economic growth was far superior to that of the
rest of the sample. The spike in 1997 is clearly attributable to the effects of the 1997 Asian
Financial Crisis. Of some interest is the smaller spike evident in 1985. According to the
World Bank’s 1986 World Development Report, the Asian region was suffering from a
substantial fall in exports due to the preceding slowdown in the US economy, and also from
a drop in commodity prices. This is confirmed in Daquila (2005), who also argues that
higher interest rates (stemming from higher rates in the US) reduced consumption and
investment in Southeast Asian countries which led to a fall in output. Daquila (2005) cites
Booth (1992) who finds that the trough of the slowdown of the Asian economies was in

1985, with recovery commencing in 1986. Focusing purely on the period between 1986 and
1996 makes the difference in growth rates between East Asia and the rest of the sample far
more apparent.36
The preceding discussion suggests it would be worthwhile to investigate the correlation
between corruption and economic growth for East Asia during the period 1986-1996.
Figure 7.10 plots corruption (using the composite index based on a simple average) against
economic growth for the East Asian countries in that period. The black dots in the chart
represent the East Asian nations while the smaller grey dots represent the rest of the
sample. The dashed lines indicate the averages for the entire sample. Most of the East
Asian countries are in the northwest quadrant of the chart because of their higher than
average corruption levels and growth rates. This provides the basis for an analysis of the
particular relationship between corruption and economic growth in East Asia.

7.3 A Corruption-Growth Model using Panel Data
The same corruption-growth model as described in Chapter 6 will be employed in this
chapter and applied to panel data. The model will take the following form: k
уit = α + βCit + ∑ λjZijt + μit (7.1)
j=1
where у = rate of economic growth
C = corruption index
Z = set of control variables
μ = error term
α, β and λ are unknown parameters to be estimated
The panel dataset employed here covers a time period spanning 20 years from 1984 to 2003
for 33 countries. As in Chapter 6, one-year lags of the control variables will be used to
control for endogeneity. All the economic data for the empirical modelling are drawn from
the World Bank’s World Development Indicators database (2005). The dependent variable
is economic growth represented by the variable GROWTH. The same control variables
used in the previous chapter will be employed in the current model with two additions as
follows:
• CURACC: rate of growth in current account balance (annual percentage change).
The current account balance is the sum of net exports of goods, services, net
income, and net current transfers.
• EDUCGDP: public expenditure on education as a percentage of GDP. This includes
expenditure on education by local, regional and national governments.
Table 7.2 reveals the correlation coefficients between each variable as part of the test for
multicollinearity during the year 1995 (using the ICRG index as the corruption variable).
GVEXGDP appears to be strongly correlated with SECENROL and EDUCGDP across all
samples. For this reason, GVEXGDP will be excluded from the regression model. There do
not appear to be any other signs of multicollinearity.
168
7.4 Estimation Results and Preliminary Analysis
Regression results are outlined in Tables 7.3-7.5. GROWTH was used as the dependent
variable and initially regressed against all the independent variables with the results being
presented in column 1 in each table. The least significant variable was then removed and
the regression was performed once again. This process was repeated, with each set of
regression results reported in a separate column, until only CORRUPT and significant
independent variables (at least at the 5% level) remained. For all regressions, the Hausman
test was used to determine whether a Fixed Effects or Random Effects model was
appropriate. The Hausman test statistic is provided for each regression together with its
corresponding p-value. A p-value less than 0.05 (5% level significance) indicates that the
Fixed Effects model is preferred.

In all three tables, it is evident that the corruption variable is not a significant explanator of
economic growth. However, although the coefficient for corruption was negative for the
CPI and WCY samples, it was positive for the ICRG sample. The significance of the other
control variables varied across all samples, but the coefficient for the growth rate of gross
fixed capital formation (GFCFRATE) was consistently positive and significant at the 1%
level. The next step is to use the composite index, achieved by taking a simple average of
the three corruption indices, to represent corruption, and re-run the regressions. The results
are presented in Table 7.6.
According to Model 7 in Table 7.6, corruption is still not significant but has a negative
coefficient (reflecting a positive relationship with economic growth). The number of
observations is now 349 as a result of using all three corruption indices, which is the
highest number in all of the regressions performed to this point. The estimated coefficients
of the gross fixed capital formation growth rate, the growth rate in exports and the market
capitalisation of listed companies as a proportion of GDP are all positive explanators of
economic growth with estimated coefficients being significant at the 1% level. Government
expenditure on education as a proportion of GDP appears to have a negative relationship
with economic growth which is also significant at the 1% level.
To take potential endogeneity into consideration, one-year lags of the control variables
were included in the model in place of the original control variables. Table 7.7 shows the
results based on the composite corruption index.37 According to the results, the lagged
gross fixed capital formation growth rate, the lagged exports growth rate, the lagged market
capitalisation value of listed companies as a proportion of GDP, and the lagged current
account balance as a proportion of GDP are all found to be significant and positively
influencing economic growth. Interestingly though, the estimated coefficient for the
corruption variable was also positive and significant at the 1% level. This suggests that low
levels of corruption led to higher levels of economic growth.
37 Results based on the individual corruption indices are provided in the appendix to this chapter. Corruption is found to be significant at the 1% level in the WCY sample, with a positive coefficient reflecting a negative relationship with growth.

7.5 East Asia: A Corrupt-Growth Club?
Since the focus of this study is on the relationship between corruption and growth before
the 1997 Asian Financial Crisis, the dummy variable Db is included. It takes a value of 1 for
those countries that were affected by the Asian Crisis (Hong Kong, Indonesia, Japan,
Malaysia, the Philippines, Singapore, South Korea and Thailand) and 0 for all other
countries. A second dummy variable, Dt, takes on a value of 1 for years up to and including
1997, and 0 for all other years. The purpose of these dummies is to isolate only
observations for the East Asian countries prior to the Crisis, to see if there was a particular
relationship between corruption and economic growth for this sub-sample. The two dummy
variables and their cross-products with the corruption variable are added to Model 7 in
Table 7.6 and the estimated results are shown in Table 7.8. As can be seen in Model 1, both
Dt and its interaction with CORRUPT is not significant. Db is not significant either but its
interaction with corruption is significant. The anomalous standard error of Db is enough to
warrant its removal from the model, along with its interaction with corruption despite its
significance. This produced Model 3. However, neither corruption nor its interaction with
the dummy variable is significant. Table 7.9 repeats the analysis after taking account of
endogeneity, i.e., using Model 7 from Table 7.7.

As shown in Model 5, the corruption variable is statistically insignificant, but its interaction
with the dummy variable is highly significant (at the 1% level). This coefficient, when
added to the corruption coefficient, gives the corruption coefficient for the portion of
observations represented by the dummy Db*Dt, i.e., East Asian countries before 1997. That
is, 0.123 – 0.617 = -0.494, which suggests that for East Asian countries before 1997 the
corruption coefficient is negative and significant, indicating that high corruption led to high
economic growth. However, this analysis can potentially be improved in two ways which
were highlighted previously in the chapter. One relates to the path of economic growth in
the sample period. It was shown earlier that there was a large spike in the growth rates of
East Asia prior to 1986, which may be interfering with the relationship between corruption
and economic growth. Another source of interference is the peculiar nature of Singapore as
an East Asian country that consistently performs very well in the corruption indices,
appearing in the top ten in the company of European and North American nations as the
least corrupt countries. To control for this, observations from 1984 and 1985 were removed
from the sample, and Singapore was also excluded. The analysis in Table 7.7 was repeated
(as Model 7 from that table cannot be used for the new sample) and the results of the final
model after following a stepwise elimination technique are shown as Model 1 in Table
7.1038.
Model 2 in Table 7.10 reports the results after the dummy variables were added to Model 1
along with their interactions with corruption, and Model 5 shows the results after
insignificant variables were eliminated in a stepwise manner. The corruption coefficient is
not significant but remains positive. Given the scale of the corruption indices, this reflects a
negative association with economic growth. More importantly is the coefficient for
Db*Dt*C, which is significant at the 1% level and negative. The resulting corruption
coefficient for East Asian countries before 1997 is therefore 0.227 – 0.881 = -0.654, which
suggests that for East Asian countries before 1997, high corruption led to high economic
growth.

7.6 Sensitivity Analysis
To check the reliability and accuracy of the simple-average technique in combining the
three different corruption indices into one composite index, a sensitivity analysis is
performed using Model 5 in Table 7.10. The results are reported in Table 7.11. Model 1 is
the same as Model 5 in Table 7.10. The next five models represent the five different
standardised versions of the composite index as discussed earlier in the chapter. The
estimated corruption coefficient is positive across all models except the one measured by
STD1, but is not significant in any of the models. This is consistent with Model 1. The
binary dummy Db*Dt is positive and significant at the 1% level across all models, and the
size of the coefficient is also similar across all models though half the size of the
corresponding coefficient in Model 1. As for the interaction of the dummy with corruption,
the estimated coefficient is negative across all models and of similar size. In two of the
models (representing STD2 and STD3) Db*Dt*C is also significant at the 5% level. The
resulting corruption coefficient estimate for East Asia prior to 1997 is 0.563 – 1.207 = -
0.644 for STD2 and 0.567 – 1.580 = -1.013 for STD3, both implying a positive relationship
with economic growth consistent with the results in Model 1.
7.7 Comparison with Other Studies
The results from similar studies analysing the effect of corruption on economic growth
using panel data are presented in Table 7.12. The first study, by Li et al. (2000), revealed
that the corruption coefficient is negative, but since their corruption index was reversed this
reflected a positive relationship between corruption and growth. All studies therefore
revealed a similar relationship. Del Monte and Papagni (2001) focused on different regions
within Italy, so the regression model only applied to one country. However the authors
opted for a different corruption measure to the indices used by other studies, namely the
number of crimes committed against the public administration per employee. Gyimah-
Brempong (2003) analysed different countries in Africa so his model examined corruption
as it applies only in Africa. The present study covers a far more broader sample. As for the
specific relationship between corruption and growth in East Asia, only Li et al. (2000)
attempted to explore this area using panel data. Their result shows a significant, negative
coefficient for corruption (and thus reflecting a positive relationship) though less so than

Notes: Li et al. (2000) reversed their corruption indices, such that a higher index value reflected a higher level of corruption. Del Monte and Papagni (2001) use “crimes against the public administration per employee” as a measure of corruption, so a higher value translates to a higher level of corruption.

the corresponding coefficient without including an Asian dummy. Their explanation was
that “during 1980-94 Asia did not pay the price paid elsewhere for corruption; in other
words, corruption may indeed have acted as grease money in Asia during this period”
(p.18).
7.8 Conclusion
This chapter has extended Chapter 6 to provide an insight into the relationship between
corruption and economic growth in East Asia over time. Examination of the path that
corruption and growth had taken over the period 1984-2003 revealed a distinct period
between 1986 and 1996 where the East Asian economies were performing far better than
their global counterparts in terms of growth, but far worse in terms of their perceived level
of corruption. Undertaking analysis of panel data revealed that although corruption had a
negative effect on economic growth globally during the twenty years prior to 2003, it was
positively impacting growth in East Asia during the ten years preceding the 1997 Asian
Financial Crisis. This lends considerable weight to the proposition purported by this study
that corruption played a substantial role in the rise of the East Asian ‘miracle’ economies
during that period. The next chapter takes this analysis one step further by analysing
corruption in a very different and distinct dimension in which it occurs in East Asia, namely
in the context of rent-seeking.

CHAPTER 8
RENT-SEEKING AND ECONOMIC GROWTH:
EMPIRICAL EVIDENCE
“The chaebols are already aware that they will have to change
their practices to keep pace with international standards. Past
governments received donations from them and returned favors.
Our government doesn't owe anything to the chaebols…There no
longer exist any strong ties between the government and the
chaebols; we are now free to follow legally-framed practices. You
can imagine the change.”
– Former South Korean President Kim Dae Jung.39
8.1 Introduction
The chaebols in South Korea have a long history of being connected with the government.
But South Korea was certainly not alone in this regard. Many East Asian countries were
riddled with patron-client networks that gave rise to rent-seeking behaviour.40 This
phenomenon was reviewed in Chapters 2, 3 and 4 as a dimension of corruption, at least as
far as East Asia is concerned. Firms establish connections with the ruling regimes in their
countries and use these connections to secure rents. This is not the same as bribe-paying.
Whereas the Shleifer and Vishny (1993) model identified corruption as the paying of bribes
to bureaucrats in exchange for resources, the rent-seeking model posits that firms receive
the resources by virtue of their relationship with the government, or specifically members
of the ruling elite. Such a model may have theoretical appeal, but does empirical evidence
support it? First of all, how can rent-seeking in East Asian countries be quantified? And
what effect does rent-seeking have on economic growth? Unsurprisingly, there are few
studies that have sought to answer these questions. A significant obstacle to such attempts
is the lack of a reliable measure of rent-seeking. Like corruption, its very nature precludes
its accurate measurement. So the first task of this chapter is to develop a measure of rent-
39 In response to being asked whether he would take harsher action against the chaebols, based on the accusation that they relied heavily on government favours (Krisher, 1998, p.3). 40 See Chapter 2 for a definition of rent-seeking behaviour.
196
seeking. It then replaces the corruption variable in the corruption-growth model developed
in Chapter 6, and the model is then applied in a similar fashion. The results are analysed
accordingly.
8.2 Measurement of Rent-Seeking
One of the limitations of analysing rent-seeking empirically is the absence of data on rent-
seeking. As with corruption, the nature of rent-seeking precludes any accurate measurement
of its extent. Some studies have sought to overcome this problem by introducing a proxy
for rent-seeking. The following section summarises these approaches.
8.2.1 Using Government Transfers as a Proxy
The proxy of government transfers has been used by Naka (2002) and Katz and Rosenberg
(1989). They draw on Tullock’s (1967) original contention that government transfers can
lead to rent-seeking behaviour, and this is reinforced by Khan (2000a). Khan argued that in
Malaysia, patron-client networks were set up by the ruling United Malays National
Organization (UMNO), established after the 1969 riots. UMNO became the dominant
Malay party in the ruling coalition (Barisan Nasional). The objective of the patron-client
networks was to transfer rents from the Chinese capitalists to the political leadership of
UMNO, via legal taxes and illegal extractions.41 These were then used to provide jobs for
Malays in state owned enterprises and subsidised loans through the banking system. Given
the natural dominance held by the Chinese in the private sector, the rents collected through
legal taxes were already large enough and the need for illegal extractions was less. The
political Malay elite who were the recipients of these rents, later engaged in their own rent-
seeking behaviour to maintain their political support amongst the wider Malay community
(Khan, 2000a).
Katz and Rosenberg (1989) analysed this transfer from the government’s point of view,
rather than society. If the government receives taxes from one sector, this is an injection
into its budget which can then be spent elsewhere. Thus Katz and Rosenberg argue that the
41 See Chapter 2.
197
resulting changes in the government’s spending pattern at the margin are a reflection of
rent-seeking behaviour. Figure 8.1 shows how Khan’s (2000a) theory of rent-seeking
through transfers can be viewed from the government’s perspective, in accordance with
Katz and Rosenberg’s (1989) theory.
In Figure 8.1 the original budget constraint faced by the government is BC. As a result of
rent-seeking, the government decides to tax one sector, and shift those funds directly into
other sectors. As a result, the economy moves from point A to point B, representing the
change in composition of the government’s spending. However, as Katz and Rosenberg
(1989) argue, this does not factor in the social cost that arises from rent-seeking. Although
there is now a bigger slice of the pie for non-taxed sectors, the total value of the pie has
diminished by the amount of the rent-seeking. So the budget constraint line actually shifts
downward by the value of the rent-seeking behaviour (which tends towards the size of the
tax but obviously can never exceed it, for that would render the whole rent-seeking process
futile) to BC1 and the economy operates at point C.
Katz and Rosenberg (1989) made an important assumption in their theory. They assumed
that the government transfers occur in response to rent-seeking behaviour, and not out of
altruism toward the public. This challenges the notion of a benevolent government which
was once a standard assumption, but has since been challenged (Lambsdorff, 2002; Ellis
and Fender, 2003). This also adds weight to the neoclassical argument that government
intervention should be kept to a minimum (Kong, 2004). However, Kong (2004) argued
that this does not explain why East Asian countries in particular were able to engage in
these transfers via rent-seeking yet still achieved successful economic development. The
key to this lies in the manner in which the rents are employed by the ‘winners’. Recall
Khan’s (2000a) argument that rents can in fact be value enhancing, if they induce learning
on the part of the recipients. Indeed this was certainly the case in South Korea, where
chaebols were only provided with rents as long as they could continue to perform and
maintain productivity (Kang, 2003). Incorporating this possibility into the analysis yields
Figure 8.2, which is a modification of Figure 8.1 to show a value enhancing transfer.

In Figure 8.2, the economy once again moves along the initial budget constraint BC from
point A to point B, but as a result of the rent recipients investing their rents productively,
the economy is able to achieve growth despite the initial waste of resources. So the budget
constraint initially shifts down from BC to BC1, but the value-enhancing rents push the
economy towards point C, on a new budget constraint BC2 which is higher than the original
(BC).
To test this empirically, one would have to regress growth against rent-seeking behaviour to
determine whether this was the case at least in East Asia. The trick here is to determine a
measure of rent-seeking. Lack of data precludes the use of government transfers, so Katz
and Rosenberg use changes in government expenditure within individual sectors as a proxy
for transfers.42 This assumes that changes in government spending have nothing to do with
government policy and are purely and wholly a result of rent-seeking, and Katz and
Rosenberg acknowledge that this is a limitation in their approach. This technique however
is best suited to the present study as data on government spending is readily available.
8.2.2 Other Measures
There are also a number of other methods employed in order to measure rent-seeking.
Studies such as Bhuyan (2000) benefit from availability of data on precise elements of rent-
seeking. Bhuyan analyses the US food industry in particular and measures rent-seeking by
adding together the salaries, wages and fringe benefits of employees in Political Action
Committees and lobbying organisations; political contributions to federal congressional
candidates; amount spent on legal services; and the amount spent on office space rental by
lobbying organisations. Cole and Chawdhry (2002) measure rent-seeking with several
variables. One variable represents the size of the US state government bureaucracy, which
is defined as the proportion of government employment in a state’s wholesale retail and
trade sector. Another variable reflects the number of interest organisations registered to
lobby in the state’s legislature, and the number of dollars behind each organisation
(measured as the real gross state product divided by the number of organisations)
constitutes a third variable.
42 Naka (2002) was fortunate enough to gain access to data on government transfers in Japan.
201
The availability of data is crucial to the success of any measurement technique. Sometimes
this problem can be circumvented if the analysis focuses on a very specific country, sector
or dimension of rent-seeking. Naka (2002) examines rent-seeking in Japan as a cause for
the slowdown in that country’s economic growth during the 1990s. Of the 47 Japanese
prefectures, those that were strongholds of the ruling LDP party were consistently over-
represented in Parliament as a result of electoral designations. They consequently benefited
disproportionately from shares of budgetary transfers from the government – and this is
what Naka primarily uses as a measure of rent-seeking. Naka (2002) also found that
distribution of public fixed investment expenditure (another measure) across prefectures
was not strictly based on population because some prefectures received greater shares of
investments than others. Specifically, those prefectures in question were mainly small rural
prefectures and are represented by the ruling LDP which has a strong rural base. Of the top
ten recipients of investment expenditure per capita in 1990, only one, Tokyo, was a large
metropolitan prefecture, the rest being small rural ones. Khwaja and Mian (2005) consider
rent-seeking in Pakistan which takes place through loans from government banks given to
‘political’ corporations, i.e., corporations whose director has participated in an election. The
amount of social waste associated with this rent-seeking is measured as a function of the
default rate on the corresponding loans.
One proxy for rent-seeking is the size of the rent and the associated deadweight loss in
Tullock’s (1967) original model of rent-seeking which can be calculated algebraically. For
example, Del Rosal and Fonseca (2000) tackle the issue of labour unrest in the pursuit of
higher wages, and argue that this also is a form of rent-seeking. This unrest is measured as
a function of the prevailing wage rate, the number of lost days of work due to the strikes,
and the price elasticity of labour demand. In a similar manner, Posner (1975) investigates
the social costs associated with the creation of a monopoly, and calculates the rent-seeking
as a function of the resulting fall in output and rise in price, as well as the elasticity of
demand.
Sobel and Garrett (2002) collect data on US industries and divide their sample into
industries based in US capital cities and those based in other cities, to measure the extent of
rent-seeking in capital cities. This is based on the theory that rent-seeking will take place in
capital cities as it is easier to gain direct access to policymakers. For example, Sobel and
202
Garrett measure the number of firms per capita in the legal services sector in US capital
cities, and find that there are nearly one and a half times as many compared to non-capital
cities, which indicates the presence of rent-seeking in capital cities. Murphy et al. (1991)
believe that rent-seeking is a result of misallocated ‘talent’ in an economy. When allocated
towards pure entrepreneurship, talent can lead to efficiency, and engineers are an example
of this. The authors contend that lawyers represent the opposite – their talent is directed
towards rent-seeking which ultimately impedes growth. College enrolments in engineering
are used to measure efficient allocation of talent, while enrolments in law are used as a
proxy for rent-seeking. Mudambi et al. (2002) use an index of economic freedom from
Gwartney, Lawson and Block (1995) as a proxy for rent-seeking, and simply invert the
index values such that a high level of freedom equates to a low level of rent-seeking. The
current study will develop a new measure of rent-seeking based on the Katz and Rosenberg
(1989) approach outlined in Section 8.2.1. This will be explained in the next section on data
issues.
8.3 Empirical Analysis
8.3.1 Data Issues
For the present study, data on government expenditure was collected from the IMF’s
Government Financial Statistics database. To ensure consistency, data entitled “Budgetary
Central Government” was used. This provided amounts of government spending classified
according to the following sectors: general public services; defence; public order and
safety; economic affairs; housing and community amenities; health; recreation, culture and
religion; education; and social protection. A total of 113 countries comprised the initial
sample, but this was narrowed down to 104 after omitting countries for which data was not
available for all sectors.
To explain the Katz and Rosenberg (1989) method, consider the following example of an
economy with $100 budget, and two sectors, A and B. Sector A is allocated $30 (or 30% of
the budget), and Sector B has the remaining $70 (70%). Assume that in the next period, the
government increases its budget by $50 to $150. Out of this increase of $50, $20 goes to A
and $30 goes to B. A now has $50 out of the $150 (or 33%) and B has the remaining $100
203
(67%). Katz and Rosenberg (1989) firstly took the absolute value of the change in
proportions. This gives 3% for A and 3% for B. These values are added together, giving
6%. To avoid double counting, the 6% is divided by 2, giving 3%. Katz and Rosenberg
(1989) argue that this 3% of the budget has been lost to rent-seeking.
However this is a misleading estimation for two reasons. Firstly, the change in A's
proportion, from 30% to 33% is not an increase of 3%, but rather an increase of 3
percentage points. So to classify the 3 as a percentage is erroneous. Also, the dollar value of
the rent-seeking works out to be (20+30)/2 = 25, which is neither 3% of the original budget
of $100, nor of the new budget of $150.
Secondly, the Katz and Rosenberg (1989) method only looks at proportions. So in that
same example, if A had only got $15 out of the extra $50 in the second period, then A's
total would be $45 out of the $150, which is 30%. This represents no change in proportion,
but A has received $15 more funding which in all fairness should be treated as a result of
rent-seeking.
To overcome these two flaws, the present study modified the Katz and Rosenberg (1989)
approach. Instead of looking at proportions, this study analysed the difference between
spending in each sector over consecutive years as a whole number. The absolute value of
these differences in a given year were added up across sectors, and divided by two to avoid
double counting. This gives a number (not a proportion) expressed in the country's local
currency, which represents the value of rent-seeking behaviour. Dividing this number by
the new budget expresses the rent-seeking loss as a proportion of government spending.
This set of values now represents an alternative measure of corruption.43
8.3.2 Preliminary Analysis
Table 8.1 provides the total value of rent-seeking as a proportion of the government’s
budget using the measurement outlined in the previous section. It is not possible to directly
compare the rent-seeking values in Table 8.1 with the data in Chapter 6 because the data on
43 This study acknolwedges that the Katz and Rosenberg (1989) methodology still has some remaining limitations.
204
government budgetary expenditure on which the rent-seeking values are based does not
cover all the countries in the Chapter 6 dataset. However, a quick glance at Table 8.1
reveals that, with the exception of Canada, the more developed countries are concentrated
towards the bottom of the table, indicating a low level of rent-seeking behaviour. This is
consistent with the findings of Katz and Rosenberg (1989) as shown in Table 8.2, which
reveals their index of rent-seeking based on the average rent-seeking between 1970 and
1985 for 20 countries. Due to the data restrictions, only two East Asian countries feature in
the present study, namely, Indonesia and South Korea. This renders any attempt to
investigate the particular effect of rent-seeking on economic growth in East Asia futile.

The same set of control variables used in Chapter 6 will be used in this chapter. The only
difference in the model is the corruption variable, which will be represented in this chapter
by the variable RENTSKG, as rent-seeking will be used as a proxy for corruption. As in the
previous two chapters, the issue of endogeneity will also be addressed. The next section
provides the results of the regression analysis.
Preliminary regression results are outlined in Table 8.5. Model 10 shows that while
GFCFRATE, SECENROL and EXPRATE are all statistically significant, the corruption
variable RENTSKG is not. However, the sign of the coefficient is positive, indicating that
higher levels of corruption (in the form of rent-seeking) are associated with slower
economic growth. One issue that may be confounding the results is the existence of
endogeneity. To control for this, one-year lagged values are used to replace all the control
variables excluding LNGDP85. The results are shown in Table 8.6.
Model 11 in Table 8.6 reveals the final model after following a stepwise elimination
technique. The one-year lags of MKTCAP and GVEDGDP are the only significant control
variables, and the RENTSKG coefficient once again is not significant but this time it is a
positive coefficient, indicating that an increase in rent-seeking would lead to an increase in
economic growth. At this stage, an examination of the standardised residual plot shown in
Figure 8.4 revealed an outlier (i.e., outside 2 standard deviations of the mean). When this
outlier was removed, MKTCAP1 was no longer significant and was removed from the
model. Once again, three outliers were identified in the new residual plot, and these were
also removed. The regression was rerun, and the results are shown as Model 12 in Table
8.6. Interestingly, the rent-seeking coefficient is now positive and statistically significant at
the 5% level, indicating that an increase in rent-seeking leads to an increase in economic
growth after controlling for the problem of endogeneity. This result is consistent with the
findings in previous chapters, and shows that rent-seeking does indeed represent a
particular dimension of corruption.

How do these findings compare with those of previous studies? Only two studies have
performed similar regression analyses in order to determine the impact of rent-seeking on
economic growth. Murphy et al. (1991) did not even attempt to measure rent-seeking,
choosing instead to use the number of law institutions as an independent variable in a
regression against economic growth for 91 observations over the period 1970-1985. The
coefficient was found to be negative but not significant, and the authors argued that the
negative sign implied that rent-seeking was negatively associated with growth based on the
notion that an increase in the number of lawyers would tend to increase the extent of
lobbying. The other study, by Cole and Chawdhry (2002) analysed 344 observations
between 1980 and 1990 and used the number of interest organisations registered to lobby in
a state’s legislature as a proxy for rent-seeking. Their resulting coefficient was also
negative, but significant at the 1% level. Clearly, the results from this study are unique and
far more rigorous given that a reasonable attempt was made to measure rent-seeking and
incorporate it directly into the regression model, rather than simply relying on a proxy.

8.4 Conclusion
This chapter proposed rent-seeking as an alternative model of corruption. This provides an
alternative to the Shleifer and Vishny (1993) principal-agent model that is popular in the
literature. The purpose of this chapter was to test whether the use of rent-seeking
empirically generated results which are consistent with the use of corruption indexes, and
could therefore be used as a proxy for corruption. In Chapter 6, a cross-sectional analysis
was performed on corruption and growth and it was found that corruption had a positive
impact on economic growth. In this chapter, corruption was measured as rent-seeking
through the introduction of a new rent-seeking index based on the modification of earlier
theories, and the index is comparable to existing corruption indices. The estimated
coefficient was found to be positive and statistically significant at the 5% level suggesting
that rent-seeking is positively related to economic growth.
CHAPTER 9
SUMMARY AND CONCLUDING REMARKS
9.1 Introduction
This study investigated the relationship between corruption and economic growth. In
particular, the study focused on the peculiar relationship between high corruption and high
economic growth in East Asia prior to the 1997 Financial Crisis. The literature to date has
been vast in the field of corruption and growth, yet few studies have attempted to analyse
East Asia exclusively. Even fewer have used panel data analysis and rent-seeking as a
proxy for corruption. This chapter presents a summary of this study’s findings and
identifies ways in which this study’s analysis can be improved. This provides the basis for
further research. The chapter closes with some concluding remarks about corruption and
economic growth in East Asia.
9.2 Summary of Findings
The literature tends to have a myopic view of corruption, viewing it synonymously with
bribe-paying and defining it as the misuse of public office for private gain. Based on this
definition, corruption tends to be modelled under the Shleifer and Vishny (1993) principal-
agent framework. This study argued that such an analysis was too narrow, and failed to
capture the very different ways in which corruption manifests itself. This is no more
apparent than in the case of East Asia. This study has shown that rent-seeking can also be
viewed as a form of corruption in reference to East Asia, conceptually at least. A review of
the empirical literature examining corruption and growth revealed that few studies had
analysed East Asia independently.
To examine the relationship between corruption and economic growth, this study needed
firstly to determine an appropriate measurement of corruption. The only available measures
of corruption are indices published by a variety of international institutions. These indices
were analysed and found to be largely consistent in their ranking of countries based on their
perceived levels of corruption, however it was found that the error of interpreting
217
corruption as mere bribe-paying was highlighted in the World Bank’s World Development
Report (1997). Based on surveys which asked two separate questions about corruption and
bribery, the Report found that while people in a given country deemed it to be highly
corrupt, they did not simultaneously agree that there was a high degree of bribe-paying.
Thus, in the survey respondents’ minds at least, there appeared to be a difference between
corruption and bribery. This lent support to this study’s assertion that corruption should be
viewed a little more broadly.
Moving on to the regression model, a cross-sectional analysis of 141 countries considering
data for 1996 was conducted in Chapter 6 based on the World Bank’s KKZ index. The
results indicated that there was some evidence that corruption was positively related to
economic growth, but the evidence was rather weak. After controlling for possible
endogeneity problems and running a series of sensitivity analyses with different indices in
place of the KKZ, corruption was found to have a significant positive impact on growth in
the presence of two different indices. However, when East Asia is considered separately
through the use of dummy variables, no statistically significant relationship was found.
A panel data analysis was then undertaken on a sample of 33 countries over 20 years (1984-
2003). The corruption indices were averaged to form a composite index, but the model did
not yield any noteworthy results even after using alternative indices in place of the
composite index and after controlling for endogeneity. However, after excluding Singapore
as an outlier in East Asia (due to consistently exhibiting low levels of corruption over time)
and after excluding the years 1985 and 1986 (which saw extraordinarily low growth rates
for East Asia), the results were striking. The resulting corruption coefficient for East Asian
countries before 1997 implied that high corruption led to high economic growth. The
coefficient was significant at the 1% level. A similar result was found when sensitivity
analyses were conducted based on different forms of the composite corruption index (i.e.,
combined using different standardisation techniques).
A concise literature review of empirical studies involving rent-seeking revealed that very
few studies undertook regression analysis using rent-seeking due to measurement
difficulties. This study proposed a measure of rent-seeking by extending the work by Katz
and Rosenberg (1989). Rent-seeking was then substituted for corruption in a cross-sectional
218
model (not enough data was available to warrant panel data analysis) and applied to a
sample of 104 countries in 1996. After controlling for endogeneity the corruption
coefficient was found to be positive and statistically significant at the 5% level. This held
for all countries in the sample which included some East Asian countries, however there
were not enough countries to generate meaningful results for the East Asian region.
9.3 Concluding Remarks
Corruption and Growth
The empirical analysis in this study revealed that a positive relationship existed between
corruption and economic growth in East Asia prior to the 1997 financial crisis. However,
this study is not implying that countries should be corrupt in order to achieve growth.
Rather, this study shows that if a country is already corrupt, the corruption may not
necessarily impede that country’s economic growth. The existing literature overwhelmingly
argues that corruption is an impediment to growth, but this study has identified a particular
region where corruption was synonymous with high levels of economic growth. Figure 9.1
below plots the economic growth of countries who appeared in the 2005 edition of
Transparency International’s Corruption Perceptions Index (CPI) against their corruption
scores. The dashed lines represent the average values for the sample, and the large black
dots mark the seven East Asian countries which have been the focus of this study. Unlike in
the period 1986-1996, the East Asian countries do not congregate in the northwestern
quadrant of the chart, which equates high levels of economic growth with high levels of
corruption (given that a low CPI score reflects a high degree of perceived corruption). This
does not contradict the findings of this study, which do not suggest that corruption is
always synonymous with high economic growth. Rather, it refutes the inverse of that theory
– that low corruption is necessary for high economic growth. In the case of East Asia,
between 1986 and 1996, that was certainly not the case, and provides the basis for further
research into the nature of corruption and its effects on an economy.
219
Part of the problem with existing studies on corruption lies in their measurement of
corruption. Indeed, its very nature precludes its accurate measurement. However, there are
alternative ways in which corruption can be viewed. Bribery is one, and rent-seeking
another, as this study has shown. But there remain many more. For example, if a country is
deemed to be corrupt, one would expect the profits from such corrupt activities to be stored
in bank accounts somewhere. One could investigate the link between a country’s banking
Further Research
Furthermore, this study also reveals how corruption is not necessarily the same as bribe
paying. In Chapter 5, it was shown that one particular corruption index yielded results
which implied that corruption and bribe paying were separate. The analysis in this study
confirmed that rent-seeking is one particular dimension of corruption and that it is more
applicable to East Asia than ordinary bribery, which is how the literature tends to view
corruption.

system and the taxation authority. Is there full disclosure from the banks to tax authority?
Do banks disclose amount of funds held and the amount of returns from bank investments?
This data could then be compared with CPI data or other corruption index scores.
One could also look to the opportunities for corruption, such as countries which receive
large amounts of foreign aid. This could be measured against the distribution of wealth
across a country. An investigation into whether politicians’ personal wealth is correlated
with their connection to aid programmes could potentially yield interesting results.
Especially where aid projects are aimed at improving productivity, one could explore
whether the project was successful or not, and in the cases where they were unsuccessful,
whether this tended to occur in countries deemed more corrupt according to the CPI and
other indices. At a broader political level, one could even examine the relationship between
donor countries and the recipient developing countries’ voting behaviour at the United
Nations, i.e., if they receive a large donation from a developed country, do they then vote
for their proposals at the UN?
