Abstract
This thesis aims at analyzing the drivers of provincial government spending on health care,
education and municipal services from the perspectives of the median voter and political budget
cycle models. A panel of province-level data for the period 1989 to 2009 is used with FGLS and
GMM estimation methods. The results show that median income is positively related with both
health and education spending, while the tax-price faced by the median voter is negatively
associated with both health and municipal services spending. Population density has a positive
link with education spending but inversely related to municipal services spending. Increases in
income inequality raise provincial spending on education and municipal services. The effects of
the age-cohorts on these expenditures are program-specific.
The predictions of the political budget cycle models indicate that although there is a tendency
for the expenditures on these three programs to increase in election-years, only the cyclical
effects on health and municipal services are statistically significant.

Chapter 1: Introduction
What drives government expenditures on goods and services? This constitutes a central question
in the public finance and public choice literatures. Over the past few decades, a number of
theories have been developed to account for public sector spending on goods and services.1 This
thesis aims at addressing a specific aspect of the above question relating to Canadian provincial
government spending on education, health care and municipal services by applying two of those
theories. The driving forces behind these three spending components are analyzed in the context
of the median voter and political budget cycle models.
Health care, education and municipal services are core public spending programs that jointly take
a large share of the provincial government’s budgets. It is therefore important to find out what
makes the provinces spend more or less resources on these programs. In doing so, two separate
empirical analyses are carried out, one to test the median voter hypothesis and the other for the
political budget cycle model. The provincial government disaggregated expenditure data on
education, health care and municipal services as well as data on provincial parliamentary
political variables from 1989 to 2009 are used.2
The constitution of Canada makes the provincial government spending and provincial
parliamentary political variables appropriate for testing both the median voter and political
budget cycle hypotheses, especially with respect to fiscal expenditures on health, education and
municipal services. Canada has a federal system of parliamentary government with
responsibilities and functions shared amongst federal, ten provincial and three territorial
1 See Hybeck (1998) for the discussion on the twelve-fold taxonomy on the growth of government.
2 Municipal spending in this analysis is made up of expenditures on protection of people and properties (courts of
law, correction and rehabilitation services, and policing and regulation measures) recreation and culture (recreation,
culture- libraries, art galleries and museums, broadcasting) and housing.

governments.3 The provincial legislature is a parliamentary democracy where the legislative
assembly is elected through competitive election. Moreover, in agreement with the constitution
each province is autonomous and the constitution act of 1982 gives exclusive provincial
jurisdiction over its level of expenditures and revenues generation.4 This
suggests that in the key
areas of health, education and municipal services that are considered to be core in public interest
are under the jurisdiction of provincial legislatures who are themselves directly accountable to
the electorate.5
1.1 Government Spending from the Perspective of the Median Voter Theorem
Since the pioneer works of Bowen (1943), Black (1948) and Downs (1957), there have been
various versions of the median voter model. Some of these models account for the size of the
public sector through policy-making decisions including the provision of public goods
(Borcherding and Deacon, 1972; Bergstrom Goodman, 1973).
The median voter model postulates that majority rule decision will always produce the outcome
most preferred by the median voter, irrespective of the institutional settings. Downs (1957)
asserts that in competitive elections where voters decide on two parties or two policy choices the
outcome of the elections always correspond to the position of the median voter. That is, policy-
makers are compelled by electoral competition to choose expenditure levels that maximize their
votes. They achieve this by adopting platforms that are closer to the ideal policies preferred by
3 The ten provinces are British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, Newfoundland and
Labrador, Nova Scotia, New Brunswick and Prince Edward Island and the three territories are Northwest Territories,
Nunavut and Yukon. 4 See the Constitution Act , 1867 under Subsection 92(2) for the regulation governing provincial governments’
revenue generation. 5 In the area of health care and education, although the federal government supports the provincial governments
through Canada Health Transfer (CHT) and Canada Social Transfer (CST) its involvement is indirect as per the
constitution.

the median voter (Holcombe, 1989). Thus, the output produced by the public sector is
understood to be driven by the preferences of the median voter. The median voter model by
implication acts as a “matching function” which associates voters’ preferences to the ideal policy
choices. It follows that the demand for public sector output is driven by the demand of the
median voter. Therefore should any of the determinants of the median voter’s demand change it
would affect the expenditure level of government for that output.
In this thesis, the hypothesis that provincial government spending on health, education and
municipal services are stimulated by certain economic factors as well as some social and
demographic factors that represent the preferences of the median voter is tested. To the best of
my knowledge, there has not been empirical work in economics that has applied Canadian sub-
national government spending data to explain the size of provincial governments from median
voter perspective. One contribution of this thesis is to fill that vacuum.
1.2 Government Spending from the Perspective of the Political Budget Cycle Hypothesis
The political budget cycle hypothesis is based on the idea that incumbents behave
opportunistically and manipulate electoral outcomes by altering macroeconomic variables.
Specifically, opportunistic incumbent governments may capitalize on political-market
imperfections like information asymmetries to signal their competences in order to increase their
chances of re-election (Rogoff and Sibert, 1988 and Rogoff, 1990). They achieve this by
stimulating their economies with expansionary fiscal and monetary policies before elections. The
persistence of such pre-electoral manipulations result in “periodic fluctuations in a government’s
4
fiscal policies induced by elections” (Alt and Lassen, 2005) generating a political budget cycle
phenomenon which has its roots in the pioneering theoretical framework of Nordhaus (1975).6
Government fiscal and monetary policies have been found to be more susceptible to pre-electoral
manipulation in developing countries than developed economies (Shi and Svensson, 2002).
Rogoff’s (1990) model focuses on disaggregated government spending rather than the overall
expenditure level. The empirical research implication from the model is that government can
maintain a balanced budget but still will find means to score “political points” through altering
the composition of its spending. This signalling is accomplished by focusing on more ‘visible’
spending in the election-year than capital investment which takes longer period to be visible. A
rational voter in a developed economy like Canada is known to be aware of government budget
constraints at a point in time and intertemporally. Evidence shows that although voters like low
taxes and high government spending they are fiscally conservative. Voters rather punish
incumbents who engage in pre-electoral manipulation that result in deficit. Therefore an
opportunistic incumbent who understands the rules of the game and knows the environment he
finds himself in, is more likely to signal by altering the composition of the budget rather than the
overall level.
The hypothesis that provincial government spending on health care, education and municipal
services exhibit periodic fluctuations induced by elections is tested in this thesis.
6 Political Business Cycle (PBC) studies the possible effects of politics (elections) on the real economy such as
GDP, growth rate and unemployment. Due to possibly lack of empirical evidence (Drazen, 2001) and the fact that
government does not directly control real economic variables (Shi and Svensson, 2003) there have been shift of
focus from the study of political business cycle to political budget cycle.

1.3 Overview of Provincial Government Disaggregated Expenditures
The trend of provincial governments’ expenditures on health, education and municipal services
within the study period, 1989 to 2009 is examined below.
1.3.1 Provincial Governments’ Health Expenditures as a Percentage of GDP
The provincial government health expenditure as a percentage of GDP is depicted in figure 1.1.
In general, the provincial government health spending as a share of GDP shows a fairly steady
level for all the ten provinces from 1989-2009. However, between 1992-1996 there was
downswing in the percentage of GDP provincial governments devoted to health care but it started
rising steadily after 1997.7 In 1989 the average provincial governments’ health spending as a
percentage of GDP was 5.8, rising gradually to 6.9 by 1992. This declined swiftly afterwards
reaching 6.0 in 1997. It took an upward trend after 1997 and by 2009 the average provincial
government expenditure as a share of GDP has peaked to 7.8 percent. From 1989 to 2009, the
total growth rate in provincial health expenditure as percentage of GDP was highest in Prince
Edward Island with total growth rate of 55 percent and average annual growth rate of 2.6
percent, and lowest in Alberta with total growth rate of 11 percent and average annual growth
rate of approximately 0.5 percent.
The average real per capita provincial government health spending (with 2002 as the base year)
in 1989 was $1,588. Manitoba recorded the highest real per capita level expenditure of $1,733
and the least was Newfoundland, with real per capita spending of $1,366. By 2009 the average
7 The down swing in the percentage share of GDP provincial governments devoted to health within this period was
caused by the economic down turns and rising public debt which resulted in cut back in provincial expenditures including health spending. See Organisation for Economic Co-operation and Development (OECD) 2001 report,
“Policy Brief: OECD Health at glance- How Canada Compares”

provincial real per capita spending increased to $2,927, ranging from a high of approximately
$3,540 in Newfoundland to $2,625 in Quebec.

by provincial GDP (Statistics Canada, table 384-0001)
The disparity among the provinces on how much of their GDP they devote to health spending
has persisted over the years. It clustered around 1989 with a percentage difference of only 2.4,
with New Brunswick having the highest contribution of 6.8 percent and Alberta least of 2.4
percent. However by 2009 the gap has widened by approximately 5.3 percentage difference, the
range between Prince Edward Island, highest of 10.2 and Alberta, lowest at 4.9 percent.

According to the 2009 Canadian Institute for Health Information report, the difference among
provincial health spending has persisted as a result of many factors. Among them include the
differences in relative income levels, demographic, health care needs, health care system and
structure and health personal compensation. Also, some provinces exploit economies of scale in
providing these services. For instance, Prince Edward Island has the same spending
responsibilities but tiny GDP relative to a province like Ontario.
1.3.2 Provincial Government Expenditure on Education as a Percentage of GDP
Figure 1.2 shows the provincial governments’ expenditure on education as a percentage of GDP
from 1989 to 2009. The percentage of GDP provincial governments devoted to education
increased from an average of 5.1 percent in 1989 to 5.7 percent in 1993 representing average
annual growth rate of 2.9 percent. Thereafter it assumed a downward trend falling from the
provincial average of 5.7 percent in 1993 to a low of 4.1 percent in 2007. By 2009 the provincial
average has risen marginally again to 4.6 percent of GDP.
By 2009, Prince Edward Island was the leading contributor, devoting 6 percent of its GDP to
provincial education while Ontario was still behind, at 3.5 percent. Over the 21-year period
Ontario persistently lagged behind in terms of the proportion of GDP the provincial government
devoted to education. There was a fair deal of dispersion amongst the provinces in terms of what
percentage of their GDP they spend on education.
However, in terms of expenditure in levels, the real per capita (with 2002 as the base year)
provincial governments’ expenditure on education averaged $1,355 in 1989 and by 2009 it has
reached an average of $1,755, a 1.4 annual growth rate. This overall decline in the provincial

governments’ expenditures on education can be partly accounted for by a substitution of private
sector spending on education in place of government spending.8
1.3.3 Expenditure on Municipal Services as a Percentage of GDP
Figure 1.3 shows the percentages of GDP provincial governments spent on municipal service
from 1989 to 2009. For the 21-year span, provincial governments’ expenditure on municipal
services has generally been fluctuating within 1 to 2 percent of provincial GDP for all the
provinces. Newfoundland for the first ten years was using above 2 percent its GDP. Nova Scotia

on the other hand has been spending less than 1 percent of its GDP on municipal services from
1995 to 2009. The average provincial expenditure on municipal service as a percentage of GDP
was 1.5 percent in 1989 and rose slightly to 1.6 by 1992. Thereafter it started declining to its
lowest at 1.3 percent in 2007 and began to rise marginally to an average of 1.5 percent by 2009.

The rest of this thesis is organised as follows. Chapter 2 has two separate sections under
literature review: one on the median voter theorem and the other on the political budget cycle
hypothesis. Chapter 3 describes the data used in the analysis as well as the econometric
methodology adopted to model the data. Chapter 4 is devoted to the results with their attendant
policy implications. Chapter 5 concludes this thesis.

Chapter 2: Literature Review
This chapter has two main sections. The first part reviews the related literature on the median
voter hypothesis, while the second part is devoted to the literature on the political budget cycle
models.
2.1 Median Voter Theorem
The median voter model since its inception has been adapted to explain various public sector
decisions-making by operationalizing it to fit the institutional structure. The prediction of the
median model under its traditional assumptions is that majority rule decision will always produce
the outcome most preferred by the median voter, irrespective of the institutional settings.
Hotelling (1929) in his article “Stability in Competition” describes how a political competition
can be related to the competition faced by entrepreneurs in private markets. He argues that in a
product market, entrepreneurs standardize their product so that it does not look entirely different
from the existing products on the market. This is done so that entrepreneurs do not lose the old
buyers of the products in addition to the new customers being targeted through a price war. He
relates this to the political contest by arguing that the competition for votes between two political
parties compels them not to take too sharp opposing positions for which the voter can clearly
choose one. The competing parties make their political platform similar in order to capture a
majority of the votes. This is because a departure from this common median position is likely to
lead to massive vote lost to the party. He concludes that in equilibrium both parties adopt
platforms that appear to converge on the median during majoritarian voting.
After Hotelling (1929) revealed the essence of the median position in decision making, Bowen
(1943) was the first to indicate how the median voter influences the outcome of voting systems.
11
Using an example of referendum voting on the amount of public education to provide, he
illustrates that the optimum quantity depends on the preference of the median voter. In Bowen’s
setup, voting is used as a proxy to determine the preference of the individuals which reflects their
marginal rate of substitution between a social good and the amount paid in taxes. He shows that
when the cost associated with the provision of the good is known, the median position gives an
indication as to the quantity that can be provided. Moreover he posits that when the individuals
vote on increments rather than on the quantity to be provided, the ideal position will be where the
marginal rate of substitution equals marginal cost. That position corresponds to the median
position where the votes are equally divided. In the equilibrium, the decision on the quantity of
public good to be provided under the simple majority decision in a referendum is the quantity
most preferred by the median voter.
However, the median model was clearly specified with its underlying assumptions by Black
(1948). In his quest to develop economic theory concerning how voting or a group decision is
arrived at in a setting where actors hold diverse views, he analyzed how a committee chooses an
outcome by majority rule. He made the following explicit assumptions underlying the median
voter model.
1. All alternatives to be voted on can be placed in one continuous dimensional space.
2. The preferences of each voter have a single peak and voters prefer outcomes closer to
their most preferred choice than distant ones. That means voters have ideal point on their
preference scale that give them the highest utility.
3. Voters can rank the alternatives in some decisive order of preferences and they vote
according to that order.
12
4. The outcome is determined using simple majority voting rule.
Based on these assumptions he argues that when motions are tabled and each alternative is
placed against one another, the winning motion is the one most preferred by the median voter
and it defeats each other by a simple majority rule. He demonstrates the importance of single
peakedness in such a voting system. Without that assumption there will be no motion which will
get at least a simple majority over the others to emerge as the clear winner under such a majority
voting system. In a committee with an even number of members he shows that once the position
of the median voter’s optimum is given the voting outcome can be determined.
In addition, Downs (1957) conceptually enriches the median model by providing deeper analysis
of how the median voter theorem determines the outcome in a political competition of a two-
party system as well as a multi-party system. Under the assumption of single peakedness of
voters’ preferences and left-to-right ordering of political parties in accordance with voters’
agreement, he advances Hotelling’s (1929) argument. He shows that in a competition between
two parties, the political parties’ platform converge to the preference of the median voter if the
distribution of voters follows the normal distribution. He argues that voters favor a candidate
whose policies are closer to their most preferred choice. The party who gets the median voter’s
vote also gets most of the votes on both side of the median voter and since majority of the votes
is centered at the median position. It follows that the party who wins the election is the one that
wins the median voter’s vote. This motivates both parties to move their political platform from
the extremes towards the center where the median voter is located. Under such circumstance the
policies of both parties does not differ entirely. In equilibrium it leads to efficient stable
democracy. He shows that when the distribution of voters has a unique mode, a multiparty
system does not survive except in a two-party system.
13
Below is an illustration of how the median voter model applies to a two-party contest.
In the diagram, the horizontal axis represents left to right ordering of the alternatives to be voted
on. The vertical axis represents the number of voters who vote for a particular alternative at the
optimum position. Point M is the median position and the distribution of votes is symmetric. In a
contest between two parties (party X and party Y), for a party X to win it needs one more than
half of the votes to favor a measure for it to be approved, under simple majority voting rule.
Suppose there are possible policies, ranked from most conservative to most liberal where L,
represent most liberal and R, represent most conservative.
If party X advocates for position B on the diagram, for party Y to maximize its number of votes
it will announce a point just barely to the left of B, B-ε. ln this case, the total votes share of party
X will be the area under the curve from B to the right plus a share of the area between B and B-
ε, depending on how close the policy choices are to the ideal preferences of the voters located
14
between the positions. Party Y will get the area under the curve to the left of B-ε plus a share of
the area between B and B-ε, depending how close the preferences of the voters in that range to
the prefer policy choices. In all, party Y will get the largest share of votes. But party X knowing
the position advocated by party Y will announce a different position still to the left of B-ε. This
process will repeat itself until one party first advocates for the position M. Similarly, if party X
first advocates for position A on the diagram, party Y will announce a point just infinitesimally
to the right of A, A+ε. The process will repeat just like the above. The party which first
announces M gets half of the votes (either to the left or right depending on the position of the
other party) plus a share of the votes between the median position, M and the other party’s
position. Hence the party which first advocates for M ends up winning the election. At M, there
is no incentive for any of the two parties to continue re-strategizing. Point M is the stable
equilibrium position for a two party systems.
In the case of three-party system (party X, Y and Z), if party X advocates for A- ε and party Y
for A, for the third party entering to maximize votes, it will announce a position close to party X
or Y , but not in the middle. In this case party Z is most likely to choose a point to the right of A,
A+ε. Party Z will end up getting the largest share of the votes but party X and Y knowing party
Z’s position will announce new positions. This process will repeat itself endlessly. Assume now,
that party X is at point A-ε and point Y is at B-ε, then the new party entering is likely to
announce a position in the middle since that is likely to give him a largest share of the votes. It
will get a share of votes between its position and party X and a share of votes between its
position and party Y. If this ends up giving party Z the largest votes share, the other two parties
15
outside will converge on the middle one. Party Z will then leap to the outside to optimize its
votes. In a three-party system, these processes will repeat endlessly, with no stable equilibrium.
Hence the median voter does not apply to a three or multiparty system. Nevertheless, researchers
have used the median voter model as a metaphor for the view that electoral competition tends to
cater to the preferences of “mainstream” voters, and not to the extremes of the political spectrum.
After these theoretical frameworks were laid, the median voter model has since been applied to a
lot of decision-making processes in public choice. Bradford and Oates (1971) apply it to public
policy. Using Black’s (1948) result that under simple majority rule the outcome is the one most
preferred by the median voter, they show from their model the economic effects of both lump-
sum grant and matching intergovernmental grants to political units. They maintain that if the
members of a community have a fixed tax-share and the quantity of a single public good to be
provided is determined under simple majority rule, matching intergovernmental grants will yield
higher spending on the public good than the effect the same amount of grant will produce if the
community receives such grant in the form of lump-sum.
Similarly, Meltzer and Richard (1981) apply the majority rule decision to estimate the size of
government measured by the volume of public income to be redistributed. In their general
equilibrium model they argue that when the franchise is extended it changes the position of the
median voter in the distribution of income which changes productivity relatively. They conclude
that in equilibrium under majority rule an increase in the relative mean income of the median
voter increase the size of government since the tax share balances the budget and pays for voters’
the choice.
16
The first authors to use the median model as a formal basis for econometric analysis were Barr
and Davis (1966). Based on the theoretical framework developed, an ordinary least squares
estimation method was used to analyze cross-sectional data from the local governments’
expenditures in Pennsylvania. The effects of per-capita value of all taxable property and the
percentage of electorates that own property were used as explanatory variables for various
expenditure components including general government, judiciary and highways spending. Per-
capita values of all taxable properties were found to account for all the spending compositions
analyzed.
The prominence of the median voter model as a popular structural model of local public
spending for both theoretical and empirical analysis was advanced by Borcherding and Deacon
(1972) and Bergstrom and Goodman (1973). The median voter was assumed to maximize his
utility by consuming private and public goods given a budget constraint. In estimating the
median voter’s demand for a public good they incorporated the characteristics of the median
voter like the median income, the tax price, as well as some demographic, social and geographic
factors in their empirical estimation. Borcherding and Deacon (1972) use data on US states level
expenditure whiles Bergstrom and Goodman (1973) use cross section data on 826 municipalities
in US. In both studies the empirical results shows that the estimated coefficients were
statistically significant for both income and price elasticities; the income elasticities were
positive while the tax- price elasticities were negative.
Since then a lot of empirical papers have tried to test the degree of accuracy and the predictive
power of the median voter theorem. Holcombe (1980) uses referendum data on 257 Michigan
school districts to test how accurate the prediction from the median voter model is for explaining
empirical reality. He finds that the actual expenditure of an average district differs from the
17
predicted value based on the median model by less than only three percentage points. He
concludes that the median voter model best predicts election outcomes compared to competing
options. Inman (1978) tests whether there are extraneous factors other than the characteristics of
the median voter (like the median income) in a population that explain spending outcomes. In a
sample of 58 Long Island districts, more than 75 percent of the predictions were consistent with
the median voter hypothesis that the median voter in a population is a family with median
characteristics.
Pommerehne and Frey (1976) and Pommerehne (1978) both compare the explanatory power of
median income relative to mean income in a set up which utilizes public spending data from
Swiss municipalities. Pommerehne and Frey (1976) use cross section data from 74 counties and
based on the comparison between the goodness-of-fit of the two alternative specifications they
conclude that the median voter model offers a better explanation for the demand for public goods
than the alternative estimation method which made use of mean income. Pommerehne (1978),
however, polishes their original findings. In a data from 110 largest Swiss cities which were
categorized into different democratic systems, he concludes that the median income variable
performs better than mean income for a direct democracy government, while its performance
becomes weak in representative government as compare to the mean income variable.
Kӧksal (2008) applied generalized method of moment estimation to a panel data from 79 Turkish
provincial governments from 1995 to 2001. He finds the result to be consistent with the
theoretical model with income elasticity of 0.51 and price elasticity of -0.52. Similarly,
Thompson (2004) uses pooled dataset consisting of 26 sub-datasets from 12 different studies of
collective decision-making to compare the predictive power between median voter model and the
mean voter theorem. Under different cultural and institutional settings, his findings suggest that
18
under simple majority voting rule the median model predicts more accurately than the mean
voter counterpart. Aronsson and Wikstrӧm (1996) also compare the degree of predictive
precision between the median model and a statistical alternative where the median voter is
assumed in the model to be the voter with median income. Although there was little support for
the median model the estimation results were similar in both models.
Corcoran and Evans (2010) test the relationship between inequality and public spending in the
context of the median voter model. Their result is consistent with the theoretical predictions of
the median voter model that inequality reduces the median voter’s tax share, which results in
higher local spending. They apply an econometric technique to compare the performance of the
median voter model to an oligarchy choice model in a group-decision-making setting. They
employ a nested test to examine both models based on data on demand for military activities by
10 NATO alliances. The median voter model was able to explain the public demand for military
spending for some allies like Canada, Britain, and Denmark. Gerber and Lewis (2004) in their
quest to find out whether legislators actually act by the dictate of the people in their districts use
2.8 million individual-level votes to study the distribution of voters’ preferences. Their findings
indicate that in districts where the individual preferences are homogenous legislators are
constrained by the preferences of the median voter. Ahmed and Greene (2002) use a non-nested
test to compare the performance of the median model to other competing models which try to
explain government size through redistribution, theories of interest group and political
institutions. Based on the public spending data from New York counties, they find that the
median model outperforms the other matching models but did not discount the importance of the
other models when other factors that help in explaining public expenditure are taken into
account.
19
Notwithstanding the support that the median voter model has received from numerous empirical
studies, there are a few other studies especially on the theoretical front, which have questioned
the inference the model draws. Notable among them is the work by Niskanen (1971). After using
the median voter hypothesis to build a model of the demand side of bureaucratic resource
allocation of the public sector, he superimposed on it the supply side of the provision of public
goods. Based on the model, he concludes that in the equilibrium, government produces goods
and services that exceed the amount preferred by the median voter.
Critics of the median model took Niskanen’s model and its conclusion to mean that the median
model has less power to explain public sector resource allocations. Mueller (1987) observed that
the median voter is descriptive under certain conditions. Romer and Rosenthal (1982) modelled
one referenda institution in the State of Oregon and they find that school district spending
decisions follow the comparative static predictions of neither the median voter hypothesis nor the
median voter demand aggregation model.
In what seems to be a response to critics of the median model, Holcombe (1989) reviews the
literature on the role of the median voter model in explaining public sector resource allocation
decisions. In his paper after reviewing both theoretical and empirical works in support and
against the median model, he posits that the median voter model is a demand side aggregation.
This is equivalent to the market demand under simple majority decision and therefore may serve
as the basis for understanding the public sector demand. He points out that the model does not
suggest the public sector produces exactly what the median voter wants but the model suggests
that under majority rule the demand for the public sector is that of the median voter. He draws
the equivalences of the median model in the public sector to the perfect competition model in the
20
private sector. He states that supply side of the model as well as multi-peakedness of preferences
and agenda control can be incorporated to serve the desired purpose.
2.2 Political Budget Cycle Model
There is a vast literature covering the degree, nature and timing of economic policies by policy-
makers that are driven by partisan and electoral incentives in democratic political economy.
Political budget cycles emerged from a broader scope of study known as the political business
cycles. Traditionally, authors in the field of political business cycles were looking at the effects
(timing, characteristics and outcome) of elections or politics as a whole on macroeconomic
variables: inflation, interest rate, unemployment level and real GDP growth rate.
Theoretically, there are two main approaches that attempt to capture the relation between politics
and economic policy decisions by policy makers: the opportunistic approach which was initially
modelled by Nordhaus (1975) and the partisan approach of Hibbs (1977).
Nordhaus (1975) formalizes his opportunistic political business cycle model based on the simple
Philips Curve under the following assumptions:
1. Expectation is adaptive. That is, economic agents’ expectation of current policy
depends on the past policies. They also use past behaviours of policy makers to judge
future performance in order to form their voting decision. In their evaluation, they
assign more weight to recent outcomes than distant ones.
2. Voters have in their preference function inflation, unemployment level and output.
Therefore they favour incumbents who preside over stables prices, low level of
21
unemployment and high real output. Voters do not understand the short run trade-off
between inflation and unemployment.
3. Incumbents are in charge of stimulative policy instruments and they are opportunistic
in seeking re-election.
Based on these assumptions Nordhaus argues that, with the election date exogenously fixed,
office-motivated incumbents will exploit the Philips Curve’s trade-off between inflation and
unemployment. They achieve this by conducting stimulative fiscal and monetary policies to
improve the macroeconomic variables prior to elections. Naive economic agents who vote on the
basis of the performance of the economy right before election get them re-elected. After election,
a government conducts contractionary policy to contain inflation and also prepare the economy
for the next election. The persistence of this election-induced expansion and contraction of the
economy creates opportunistic political business cycles.
Although the Nordhaus model was theoretically accepted, empirically the model found little
supportive evidence. Many authors that tested the model using United States or OECD countries’
data concluded that there was a lack of significant and consistent evidence that there exist
electoral cycles in macroeconomic variables.9
In the context of the partisan approach, Hibbs (1987) argues, based on his two-party model, that
the fluctuations in the real economy associated with election outcomes are driven by ideological
differences of the political parties. He indicates that the kind of economic policies a government
pursues depends on the political party a candidate represents and their position on the political
9 See the findings of McCallum (1978), Golden and Poterba (1980), Hibbs (1987), Alesina (1988), Alesina and
Sachs (1988), Alesina and Roubini (1992) Alesina et al (1992, 1993, 1997), Alesina and Rosenthal (1995).
22
spectrum. In particular, a left wing party prefers trading-off a high level of inflation to reduce
unemployment whiles the right wing prefers lower inflation to higher unemployment.
Following the Hibbs (1978) model, many empirical works have found the model to be consistent
with the electoral and ideological incentives for macroeconomic policies of the Democratic Party
in the United State and the Socialist Party in Europe who are more inclined to lower inflation and
more averse to unemployment than their counterpart Republicans in United States and
Conservatives in Europe. However the partisan approach has little application in the developing
economies where the differences in economic and ideological objectives among the political
parties cannot be clearly defined as compared to the left-right dichotomy in the Western
countries.
The main distinctions between these two models and the research motivation leading to the
subsequent formalization of the other models in political business or budget cycles were captured
in Alesina’s (1988) paper on the classification of models. It deals with the expectation and
evaluation process of economic agents and the motivation for policy choices.
First is the argument of whether policy-makers decide on macroeconomic policy instruments
based on their opportunistic (office-seeking) motives in the sense that they are only about
winning elections, or their decisions are driven by partisan motivations. This results in
opportunistic or partisan approach groupings. Second is whether voters are not forward-looking
and they evaluate policy-makers based on the past behaviors or previous policies to take their
voting decisions. This corresponds to adaptive as opposed to rational expectation.
Based on these, the literature on electoral business cycles can be categorized into:
23
1. Opportunistic and adaptive expectations models: Nordhaus (1975), Tufte (1978)
2. Opportunistic and rational expectations models: Cukierman and Meltzer (1986),
Rogoff and Sibert (1988), Rogoff (1990)
3. Partisan and adaptive expectations models: Hibbs (1977, 1989)
4. Partisan and rational expectations model: Alesina (1987, 1988), Alesina & Rosenthal
(1995), Alesina and et al (1997)
Alesina (1987, 1988) in his seminal papers “rational partisan theory” provides a theoretical
framework and argues on the need to incorporate rational expectations into the partisan models
for it to be consistent with economic theory. In the rational partisan theory he posits that since
economic actors are rational and take into consideration decisions of policy makers, the cycles in
macroeconomic variables can only be created when monetary and fiscal policies effects happen
unexpectedly. In such a situation, when a left government is elected, once the expected change
was not anticipated, growth, employment and inflation will rise while they fall in case of a right
government. But as time elapses economic agents agree on new prices and sign new wage
contracts depending on the level of inflation. In equilibrium, real growth and employment return
to the natural level while inflation still remains. Alesina et al. (1997) concludes that the
difference between rational and non-rational partisan theories depends on whether the changes in
the macro- variables persist or disappear over the incumbent’s term in office.
Unlike Nordhaus’ opportunistic theory, both rational and non-rational partisan theories enjoyed a
lot of empirical support. Alesina et al. (1997) in separate studies with post war data from U.S and
OECD countries find evidence to be consistent with the rational partisan model with the
24
evidence being more pronounced in two-party systems. Wilensky (1976, 1981) using data from
19 OECD countries from 1965 to 1971, finds that there exist a number of correlations between
partisanship and various government policies including social, welfare and fiscal policies. But he
points out that the significance level was minimal. In the analysis of time series data from 1960
to 1977, Pommerehne and Schneider (1980) find that Australian Liberal party (right) and Labor
party (left) pursue partisan spending and tax policies. Hicks and Swank (1984a, 1984b), Swank
(1988, 1992), Garrett (1995, 1998) and Hallerberg and Basinger (1998) all find some evidence of
partisan cycles.
On the contrary, besides the lack of empirical evidences in favour of pre-electoral manipulations
in aggregate economic variables (Drazen, 2001), some of the assumptions behind the
opportunistic political business cycles models were not consistent with economic theory. The
assumption of adaptive expectations in the initial political business cycles models were
overcome by incorporating rational thinking on the part of economic actors into the subsequent
models. However, there were still some arguments against the model on the grounds that
governments do not have direct control over real economic variables (Shi and Svensson, 2003),
particularly where the country’s central bank is independent. Even currently there is ongoing
debate in the literature whether government macroeconomic policy instruments, fiscal or
monetary, have an immediate effect on the real economy.
Subsequent researches in macroeconomic game theory led to the development of models which
address those conceptual setbacks. Cukierman and Meltzer (1986), Rogoff and Sibert (1988) and
Rogoff (1990) were the earlier proponents of political budget cycle theories - the study of
fluctuations in a government’s fiscal policies especially its expenditure (levels or composition)
stimulated by elections. In particular, Rogoff and Sibert (1988) and Rogoff (1990) develop
25
signalling models. In their models incumbent governments take advantage of the political market
information asymmetries especially regarding candidates’ abilities or about the political
environment to engage in pre-electoral manipulation in macroeconomic policies like spending
(either in levels or composition), taxes and deficits to score political point on the incumbents’
competence.
In Rogoff’s model pre-electoral manipulation may be achieved by shifting government
expenditure from investments which are not readily observable by the electorates towards more
easily and promptly observed current spending. This signals the incumbent’s competence in
administering the production of public good which heightens his chances of being re-elected.
In the model, Rogoff assumes that each political candidate has a certain level of competence and
voters basically choose between candidates based on their competence level. The utility of voters
was assumed to depend on public consumption, public investment and a random shock. This
means voters rationally favour the more competent candidate because to them he has the ability
to deliver more public goods with same level of taxes. Thus the more competent policy-maker
provides higher welfare. Competence is serially correlated which makes it realistic for voters to
vote for the candidate they perceive to be more competent before the elections. The expectation
is that he will administer more public goods after the election than the one with a low level of
competence. The “competence” shock follows a moving average process of order one. That
makes successive elections independent.
The production of public good at time t by a leader with unobserved administrative competence
is given by
+ = +
26
Where is the public consumption good and is the public investment good τ is the lump-sum
taxes levied by the government. Public investment is chosen at period t and only becomes
observable and productive at period t+1. Due to information asymmetry voters do not observe
the incumbents’ current competence before elections but are aware of only the past competence
level of government. However the government knows its current competence. Under this
imperfect information voters infer about incumbent’s ability based on their observation of g.
Since the incumbent is rational and office-seeking, there is an incentive for him to signal his
competence by administering higher g with the same level of τ. Rogoff argues that signalling
takes the form of shifting government expenditure away from investment expenditure (whose
effect is observed with lag) to easily observable consumption expenditure. In a separating
equilibrium, the incumbent choice of the fiscal policy reveals his competence type. The
empirical research implication from the model is that government can maintain a balanced
budget but still will find means to score political points through altering the composition of its
spending.
Tabellini (2000), Gonzalez (1999, 2002) and Shi and Svensson (2002) all offered an extension of
Rogoff’s model to account for pre-electoral manipulation. Tabellini (2000) and Shi and Svensson
(2002) proposed political budget cycle models based on moral hazard10
of competence approach.
Their model differs slightly from the previous signalling models to the degree that in their model
both the voters and the political candidates cannot observe the politicians’ competence at the
same time. This makes the politicians uncertain about how they will overcome the economic
challenges during their tenure especially regarding the provision of the desired level of public
goods having in mind the government budget constraint. Knowing that voters are rational and
10
Lohmann (1998) was the first to adopt a moral hazard approach to study political budget cycle.
27
forward-looking who will vote for the more competent candidate, that can provide more public
goods after elections, in the model they assume that politicians can put to use a “hidden effort”
(like government short term borrowing). The electorates only observe hidden effort with a lag.
This works because voters base their voting decisions on the performance of observable
macroeconomic indicators. In the equilibrium, voters are not naive: they understand the political
environment and know the incumbent’s intentions, hence they can distinguish his actual
competence from the apparent exertion of the “hidden effort”. The conclusion from the model is
that such hidden policy used by the government to increase its performance index leads to budget
deficits before elections due to excess borrowing.
Shi and Svensson (2002) argue that the intensity of the political budget cycle depends on the
politico-institutional settings which are mainly a function of the politician’s rents from remaining
in office and the proportion of the voters who are well informed.11
They show that policy-makers
have higher incentives to remain in office through influencing electorate’s perceptions before
elections by engaging in pre-electoral manipulations if they recognize that there are more private
benefits that go with holding office. Likewise they conclude that the lower the proportion of
voters who are more informed to identify the true competence of incumbents, the higher the
chance for incumbents to manipulate fiscal policies prior to elections.
Gonzalez (1999a, 2002b) and Shi and Svensson (2000) capture the effect of the degree of
democracy on the relative size of political budget cycles. In Gonzalez’s model, the effect of two
key variables were introduced into the Rogoff’s (1990) signalling model: the cost of removing a
policy-maker from office, which captures the degree of democracy, and the probability that
11
Shi and Svensson accounted for the well informed voters by using information accessibility (availability of radio
and media freedom)
28
electorates can discover the incumbent’s true competence devoid of signalling, which measures
the level of transparency. The main prediction from Gonzalez’z model is that with a high cost of
removing policy-makers from office, incumbent governments tend to remain in office. Thus
electoral budget cycles occur in jurisdictions where removing incumbents from office come with
relatively less cost. Also she predicts that pre-electoral manipulations are reduced as the degree
of transparency is enhanced. She establishes that there is positive association between the degree
of democracy and transparency, and political budget cycles emerge in jurisdictions where the
level of democracy can be described as intermediate, where both the degree of transparency and
the level of democracy are also intermediate.
On the empirical front there have been various studies covering different aspects of political
budget cycles. Most of these studies use auto-regressive specifications where the response
variable is a policy outcome (GDP, revenue, expenditures, deficits etc) and is modelled on a set
of control and predictor variables. The control and predictor variables include some economic
variables that affect the policy outcome variables, a dummy variable capturing the effect of
elections and other unobserved variables.
Brender and Drazen (2005) provide insight as to why the strength of political budget cycles in
developed countries differs from the developing countries. They argue that political budget cycle
is a phenomenon in countries with new democracies, including both developed and developing
countries and the significance of the drift persists in a few elections after the country has made a
transition from non-democratic to democratic. They indicate that in studies that use large sample
to explain political budget cycles, it is the effect of these new democratic countries that makes
the result entirely different. Without the inclusion of the new democratic countries in the sample,
the cycle disappears. Their conclusion is that the new democracy phenomena helps explain why
29
budget cycles are larger in developing countries and countries with weak democracies since most
of the developing countries had recently made a transition into democratic rule. A key
explanation for their result is that voters in new democracies are naive to understand the
complexities of electoral manipulations, coupled with the difficulty in assessing credible
information to evaluate politicians.
Early empirical works on political budget cycles were mainly focused on the advanced
industrialized countries specifically in United States and other OECD countries. Tufte (1978)
was the first to use United States data to study pre-electoral opportunistic manipulations in fiscal
instruments. The result indicates that incumbents manipulate transfers payments like social
security and payments to veterans prior to elections. Alesina (1988) based on time series data
from 1961 to 1985 finds electoral cycle in net transfers proportional to GNP in the United States.
However, he added that when the data is extended to cover the period up to 1949, the electoral
effects go away. Similarly, Keech and Park (1989) find evidence of electoral cycles in veteran’s
benefit in United States using data from 1961 to 1978 but also remark that the evidence has
disappeared afterwards. Alt and Lassen (2006) find a positive correlation between the magnitude
of electoral cycle and the degree of fiscal transparency. Alesina et al. (1992, 1997) uses a panel
data set comprising 13 OECD from 1961 to 1993 and find that the government budget deficit
increases by 0.6 percent of GDP in election years. Barreira and Baleiras (2006) find that
government in established democracies manipulate budget composition towards current
expenditure in election elections. Their data comprises 15 European Union central government
expenditure data from 1970 to 2001. Eflthyvoulou (2011) finds evidence of electoral
manipulation in the form of fiscal deficit where the magnitude becomes stronger when the
30
election dates are fixed exogenously from a data set comprising 27 members of the European
Union from 1997 to 2008.
Recent studies have shown that electoral cycles exist in all countries, the developed and the
developing, as well as in all level of democracies. This is contrary to the initial arguments that
electoral cycles exist in only the developing countries. Ben-Porath (1975) finds in data from
1952 to 1973 that incumbent governments in Israel cut taxes before elections but adjusts them
upwards after winning elections. Likewise Brender (1999) finds evidence of pre-electoral
manipulation in fiscal policies but points out that such manipulations did not work in favor of
incumbents. Krueger and Turan (1993) find that there was pre-electoral manipulation in Turkey
particularly from 1950 to 1980. Gonzalez (1999) finds evidence of electoral cycles in
government spending in Mexico over the period of 1958-1997 in both presidential and
congressional elections.
Some other studies focused on cross-countries have affirmed the existence of budget cycles.
Ames (1987) in a study involving 17 Latin American countries from data that covers the period
from 1947 to 1982, finds that on the average government expenditure increases by more than 6
percent prior to elections and reduces by almost 8 percent after elections. In a study of 44 Sub-
Saharan African countries by Blocks (2000a), he finds evidence of both fiscal and monetary
cycles with the deficit increasing by 1.2 percent before elections. Blocks (2002b) using a sample
of 69 developing countries, finds evidence consistent with Rogoff’s budget cycle model. In his
analysis which involves only presidential elections between 1975 and 1990, the results show that
government spending shifts towards projects which are readily visible (current expenditure)
away from capital investment. .
31
Schuknecht (1996) in a study of 35 developing countries over the period of 1970-1992, finds that
governments’ fiscal balances are worsened by approximately 0.6 percent of GDP in election
years. Shi and Svensson (2002) use data set spanning from1975 to 1999, which is made up of 91
countries (both developed and developing) to investigate whether budget cycles pertains to only
developed countries. They find that on the average, the fiscal deficit increases by one percent
relative to GDP in elections years with the magnitude in the budget cycles being higher in the
developing countries than in the developed countries. The election-year fiscal balance worsens
by 1.4 percent for the developing countries as compared to 0.6 percent in the developed
countries. The source of deficit comes from a decline in tax revenue by a margin of 0.4 percent
of GDP while spending increases by 0.5 percent of GDP.
Persson and Tabellini (2002) considered how electoral rules and forms of governments affect
political budget cycles. In a data set comprising of 60 democratic economies for election periods
from 1960 to 1998, they find countries with majoritarian elections reduce its fiscal expenditure in
election years while those with proportional electoral rules increase their expenditures on
welfare, but they found election years tax-cuts as a common phenomena of both electoral
systems. Presidential governments tend to cut spending before elections and raise taxes after
elections as compared to their parliamentary counterparts. Vergne (2009) finds that election year
spending shifts from capital expenditure to more visible current spending in the areas of wages
and subsidies in data on 42 developing countries from 1975 to 2011. Barberia and Avelino
(2011) in a panel data set of 18 Latin America countries from 1973 to 2008, find that government
spending increases while tax revenue reduces by about 10 percent. Brender and Drazen (2005)
examine central governments’ expenditures, revenues and fiscal balances from 106 democratic
32
and non-democratic countries. They find that pre-electoral manipulation is higher in new
democracies than in well established democracies.
Some other studies have investigated the effects of fiscal performance on re-election fortunes of
incumbent governments. Notable among them is Brender and Drazen (2005). In a sample made
up of 74 democratic countries from 1960 to 2003, they find no support for the hypothesis that
expansionary fiscal policies help incumbent government to get re-elected. The results show that
it rather reduces their chances of being re-elected especially in the developed countries. They
find that in the developed countries where their democracies are stronger, voters punish
incumbents who preside over deficits over their term in office and election years. Their empirical
result indicates that in the developed countries a percentage increase in surplus relative to GDP
over the incumbent’s term in office induces 3 to 4.5 percent chances for incumbent’s re-election
prospect but the probability increases to between 7 and 9 percentage points if the surplus occurs
in an election year.
A lot of extensive works have been done at the sub-national level which confirms that political
budgets cycles are not confined to only the central governments. Among them are United States:
(Peltzman, 1992), Canada: (Kneebone and McKenzie, 2001; Reid, 1998), Columbia: (Drazen
and Eslava, 2005), India: (Khemani, 2004), Israel: (Brender, 2003), Russia: (Akhmedov and
Zhuravskaya, 2004) Germany: (Galli and Rossi, 2002) Italy: (Cioffi et al, 2012) and Brazil:
(Klein 2010)
Akhmedov and Zhuravskaya (2004) in their monthly data from 1996 to 2003 find evidence of
political budget cycle in local government spending after Russia made a transition into a
democratic rule. However they observe that the effect dwindles away with time and finally
33
disappears after two successive elections. Cioffi et al. (2012) test the existence of pre-electoral
manipulations in Italian municipalities from 1998 to 2006 and find that in election-years
municipal government spending increased by almost 40 euros per capita mostly from capital
expenses. Reid (1998) finds that provincial government spending, and non-borrowed revenue
exhibit electoral cycles with expenditure in the areas of transfer to persons, businesses and fixed
capital formation growing more rapidly, while revenue decreases during election periods.
Reynolds (2012) examines the tuition fees and required fees at public four-year institutions of
higher education in United States in the context of political budget cycles. He finds that tuition
and other required fees decrease by 1.5 percent during gubernatorial election years than no
election years. He finds the magnitude of the cycle increases with the level of competition in
state house elections and the effects were mostly concentrated in the districts held by an
opposition party. Kneebone and McKenzie (2001) use panel data set from 1966 to 1997 to
examine the presence of partisan or electoral cycle in Canadian provincial government spending.
They find that all political parties have a common set of attitude to suspend tax increases in
election-years. There were also evidences of opportunistic cycles where spending in visible areas
tend to increase prior to elections. On the partisan front they find that spending programs exhibit
partisan responses and such responses do not appear in policies regarding revenue.

Chapter 3: Data Description and Econometric Methodology
This chapter is partitioned into two parts. The first part is devoted to the data description on both
the median voter and the political budget cycle models. The second part of this chapter focuses
on the econometric methodology adopted to estimate both models.
3.1 Data Description
The data used is a panel data set covering the 10 provinces in Canada from 1989-2009.12
The
panel approach provides 210 observations through the pooling of the 10 cross-sections for 21
years.
The fiscal variables used in this analysis, both under the median voter and political budget cycle
models are provincial health care, education and municipal services expenditures. The three
spending categories are major program expenditure components and are core public spending.
These fiscal variables are divided by the provincial total population and adjusted for inflation
using the provincial consumer price index (2002=100) to obtain the real per capita provincial
government spending on these categories.13
Specifically, in the median voter models these fiscal
variables (measured in real per capita terms) are used as the dependent variables. However in the
political budget cycle models these fiscal variables are further converted to growth rates to obtain
annual growth rate in real per capita terms.
12
A consistent data set on disaggregated government spending at the provincial level is only available for that time
period. 13
Data on the disaggregated spending components are taken from CANSIM table 385-0002 and are measured in
nominal dollars, provincial population data from CANSIM table 051-0001 and the CPI data from CANSIM table
326-0021. The GDP data is taken from 384-0001 and is measured in millions of nominal dollars.
35
3.1.1 Data Description: Median Voter Variables
Based on the median voter model, the levels of government spending of all categories are driven
by factors that influence the demand function of the median voter. These include some
economic, demographic and social factors that characterize the preferences of the median voter.
The major economic factors are income and price. Since the median voter is not known ex ante,
following the argument of Bergstrom and Goodman (1973), the median voter is assumed to be
the individual in a particular province with median characteristics. The median voter’s income
and the income of all families are expected to be highly correlated.14
Therefore the after-tax real
median income of all families is used as a proxy for the income of the median voter. The utility
of the median voter increases in spending (consumption), therefore it is expected that taking all
other factors as given, as income increases the median voter will want to spend more and hence
the coefficient of the income variable is expected to be positive provided the good in question is
a normal good. Therefore the aggregate spending on the various programs is expected to rise
with income. The after-tax median income data is taken from CANSIM and it is converted to
2002 constant dollars using provincial CPI (2002=100).15
When demanding some quantity of public good, the median voter takes into account the cost of
the product. He considers how much of his taxes that goes into the delivery of the product as
well as the unit cost of the product. Therefore the price effect in this analysis is measured by the
tax-price index, which is the product of the tax-share of the median voter times the relative price
14
All families in this analysis include economic family of two or more persons and unattached individuals. Median
income of all families is used instead of median income of individuals so as it will be consistent with the tax-share
measure which also uses all families share of total income tax paid by the third quintile. The all families’ median
income is highly correlated with the median income of individuals, hence it can be used without giving rise to a bias
estimate. The median income of individuals is later used to check the robustness of the estimates. 15
The after -tax median income of all families is obtained from CANSIM table 202-0605 and is converted to 2002

of the good. The share of the total income taxes paid by the third quintile of the provincial
income distribution is used as a proxy for the median tax-share while the relative prices of the
fiscal variables (health, education and municipal services) are computed as the ratio of the
respective program’s CPIs (province level) to overall provincial CPI (2002=100)16
. The median
voter becomes less inclined to demand more as the tax share or unit price of the good increases,
therefore the coefficient of the tax price index is expected to be negative.
The effect of income inequality on provincial government spending is captured by the gini index
which measures the dispersion in the income distribution.17
Meltzer and Richard (1981) argue
within the context of the median voter model that as the pivotal voter’s income drops below the
average income level, the size of government budget rises through redistribution. Thus, the
expenditures on these fiscal programs will increase if we assume that these programs are
themselves redistributive. Also it can be argued that with a progressive tax system in place, as
the level of inequality increases the tax revenue allocated to redistributive income transfers will
rise, leaving less money for other programs. The theoretical arguments of inequality and
government spending are inconclusive. Therefore the sign of the coefficient of this variable
cannot be pre-determined theoretically.
16
The CPI indexes are taken from CANSIM table 326-0021 and the tax share of the third quintile is taken from
CANSIM table 202-0501. Although the health care CPI has dental and eye care components which are generally not
financed by provincial governments, there is a strong correlation between the entire care CPI and those two
components. Therefore using health care CPI to calculate tax-price of health without isolating those two components
does not give a bias estimates. There is no provincial level CPI data for the protection of people and properties
component of the municipal services. Therefore the average CPI of housing and recreation and culture is used to
represent the CPI of municipal services. 17
The gini index of an after-tax income of all families is taken from CANSIM table 202-0705.
37
Population density is expected to affect government spending through two channels.18
First, as
the size of the population increases relative to a fixed land mass, the cost for providing these
public goods and services would decrease due to economics of scale. This will reduce the tax
share of the median voter and therefore it pays for him to demand more, leading to an increase in
government spending. Second as the population density increases depending on the degree of
publicness of the good, the utility of the median voter may decrease and therefore he will vote
for more of these goods and services in order for him to maintain the same level of utility.
Provincial government spending is likely to be influenced by some demographic factors that
reflect the preferences of the median voter. This is captured through three age structures:
proportion of the children between ages 0 to five years, proportion of school going age, from
ages 6-18 years, and the fraction of the elderly population, from 65 years and above19
. The
delivery of health services to the aged as well as the young children are associated with higher
costs due to their special health needs. Also, the age groups may have different levels of
resistance to tax increases. The effects of the age groups on these fiscal spending cannot be pre-
determined.
3.1.2 Data Description: Political Budget Cycles Variables
The political variables used in this thesis closely follow the set of variables used by Reid (1998)
to study the effects of politics on government transfer payments, current expenditure on goods
and services and fixed capital formation. The same set of political variables are employed in
18
Population density obtained as the ratio between provincial total population and land mass in kilometers square.
The data on total population is from CANSIM table 051-0001 and the land mass is taken from Statistics Canada
2012, Population and dwelling count for Canada, provinces and territories. The land area excludes area under inland
water bodies, natural claims to continental shelf and exclusive economic zone. 19
The various calculations are based on the population and census table from CANSIM table 051-0001. The age
limits for proportion of school going age is based on the average provincial age for completing high school.
However in the analysis it was also experiment with age limit 6-24 years, capturing the effect of school going age up
to the university level.
38
this thesis because such variables are core in characterizing the effects that provincial elections
will exert on government expenditures on education, health care and municipal services. In order
to capture the real effect elections have on these fiscal variables there is a need to control for the
other factors that might influence government expenditure. The set of control variables
accounting for the effect of the prevailing macroeconomic conditions on these fiscal variables
are the provincial real GDP growth rate and the level of provincial unemployment rate.20
From
the perspective of the economic approach “all other things being equal”, the amount of resources
devoted to these spending categories will exhibit cyclical patterns as a result of changes in the
level of GDP and unemployment rate.
The predictor variable of interest is the election dummy variable expected to test the effect of the
budget cycle hypothesis. It takes the value one for years where provincial elections were held
and zero in all non-election years. Opportunistic spending usually occurs in advance before the
actual election date, therefore following Alesina et al. (1993) the election data were associated
with the economic data by setting the election dummy to zero if the election occurred in the first
half of year , and one for the year . From 1989 to 2009, there were 55 elections held in all
the provinces. Five of the provinces held 6 elections each while the remaining five held 5
elections each. The average duration between two successive elections was 4 years.
The other explanatory variables are the “percentage of seats” and “proportion of votes” won by
the party in government. These actually measure the size or authority of the ruling government.
It is expected that a larger size should exert an upward pressure on government spending. The
minority variable is a dummy which takes on the value one if government in office is a minority
20
. The provincial unemployment data is taken from Labour Force Survey estimate, CANSIM table 282-0086 and
the GDP data from CANSIM table 384-0001. All the political variables are obtained from Canadian Parliamentary Guide.
39
and zero otherwise. The effect of the minority variable on these spending categories can be small
or huge depending on the preferences of all legislators as a minority government has less
discretionary powers over unapproved expenditures. The “change variable” equals zero for a
continuation government and one if the current incumbent is different from the previous one
prior to the elections. Left versus right dichotomy variable indicates the position of the
government in power on the political spectrum. It assumes the value zero for right-of-center
parties and one for left-of-center parties. It measures the ideological preferences of the parties on
these programs. New Democratic Party (NDP) and Parti Québécois fall under left-of-center
dichotomy.
3.2 Econometric Methodology
In order to account for the persistence and the partial adjustments over time in the budgeting
processes and also to take care of the province-specific heterogeneity, a dynamic panel model in
the form of a one-way fixed effect error component model is considered for this analysis. The
choice of a fixed effect model over the random effect model is due to three reasons. Besides the
province-specific heterogeneity bias that fixed effects seek to correct, the economic theory
supporting the selection of these two models suggests that the random effect model is most
appropriate if the data generating process is random. This selection criterion is not applicable to
this study since the sample data comprises all the population (the ten provinces in Canada).
40
Finally, the Hausman (1978) model specification test conducted is also consistent with the fixed
effect model at one percent significance level.21
Moreover, the joint F-test conducted to find out if the dummies for all years are equal to zero
failed to reject the null hypothesis that for all years coefficients are jointly equal to zero. This
gives rise to a one-way error components model.22
The generic model estimated for both median voter theorem and the political budget cycle is of
the form:
= +
+
+ (3.1a)
where = + (3.2a)
where the superscript indexes the type of fiscal expenditure under consideration, indexes
the province, t the year, . is the common intercept, β is a
vector where is the number of explanatory variables, is the
observation of the
regressor of the fiscal variable , is the composite error term which is made up of , a
province-specific error term, and , an idiosyncratic disturbance term.
21
The Hausman test was a preliminary test conducted on the six models to be estimated. The null hypothesis
is that the preferred model is random effects against the alternative hypothesis that preferred model is fixed effect. It tests whether the unobserved effects are correlated with the regressors. The results under the various equations are ( education: Prob > Chi2 = 0000; health: Prob > Chi2 = 0.0007; municipal services: Prob > chi2 = 0.0000)
22 Under Ho: All years’ coefficient are jointly equal to zero against H1: Not all year coefficient are jointly zero.
The result are ( education: F( 20, 173) = 6.25 with Prob > F = 0.000; health: F(20, 173) = 4.33 with Prob > F = 0.0045 municipal services F( 20, 173) = 2.18 Prob > F = 0.0039)
41
The following standard dynamic panel assumptions are made with respect to equation (3.1a).
These assumptions are further tested to ascertain the best estimator to be used in analyzing the
data.

panels are heteroscedastic. ( ) = (

3.2.1 Estimated Model: Median Voter
The first set of the systems of equations which are used to explain provincial government
spending from the perspective of the median voter model are expressed as follows:
= + + + β1 + β2 + β3 + β4 + β5 +
β6 + β7 (3.1b)
= + + + β1 + β2 + β3 + β4 +β5 +

“ln” is a notation for natural logarithm. The log-log specification gives the flexibility for
calculating the elasticities.
The explanation of the variables used in the in the above specifications are as follows:

Given that │ │< 1, it generates an exponential series which decays as t increases.
Therefore the total increase in fiscal spending over all current and future years resulting from
a unit increase in explanatory variable is given by
Thus in the steady state (long run) the elasticity of explanatory variables is given by

3.2.2 Estimated Model: Political Budget Cycles
The second set of the systems of equations used to explain government spending from the
perspective of the political budget cycles are expressed as follows:
= + + + β1 + β2 + β3 +
β4 +β5 + β6 + β7 (3.1c)
= + + + + β2 + β3 + β4 +
β5 + β6 +β7 (3.2c)
= + + + β1 + β2 + β3 + β4 +
β5 + β6 + β7 (3.3c)
45
The definitions of the variables are given in the table below
3.2.3 Estimation Strategy
In order to determine the appropriate method for estimating equations (3.1b) to (3.3b) and (3.1c)
to (3.3c) some diagnostic checks are carried out to assess the properties of the data as well as the
structure of the error terms.
First, panel unit root tests are carried out to ascertain the trending behaviour of the variables.
Unit root is a major problem in the sense that regressions that involve non-stationary variables
produce standard errors that are biased, hence inferences that are drawn based on such results are
misleading. Regressions from such variables produce results that seem to give a good fit and
predict a statistically significant relationship between variables where none really exist. These
spurious regression results occur due to common trending in the variables, rather than the
underlying economic relationships (Granger and Newbold, 1974). In this study two of such unit
roots tests: Im-Pesearan-Shin (IPS) root test and Hadri LM test are conducted to determine the

order of integration.23
Since most economic variables increase over time, a deterministic trend
component is included in the test.24
Also the choice of lag order to be included is determined by
the Schwert (1989) lag order selection criterion.
The results from the IPS root test and Hadri’s test are shown Table 3.3. The IPS unit root tests
show the null hypothesis could be rejected at a significance level of 5 percent for all the variables
except unemployment rates, population density, proportion of school going age and proportion of
children. Since the power of the IPS test depends on the lag level and the length of time period,
Hadri (2000) residual-based LM test which is built on Kwiatkowski- Phillips-Schmidt-Shin test
(KPSS) for time series data is employed to aid in drawing a better conclusion. At 5 percent
significance level most of the results were consistent with the IPS test results. However, unlike
the IPS test, the results indicate that unemployment rate, proportion of school going age and
proportion of children could not be rejected under the null hypothesis that the panels are
stationary. Reconciling the two tests results and also relying on the fact none of the policy
variables shows evidence of a unit root, this study will proceed by assuming the panels are
stationary.
23
For the IPS test, the null hypothesis is that all individual panels follow a unit root process, against the alternate
that some of the panels have a unit root. Thus,
= for all i against =
On the hand, for the Hadri’s LM test, the null hypothesis is that there is no unit root in any series (stationary) against
the alternate that the panels have a unit root. 24
Economic theory is of less help as to whether deterministic trend needs to be included in a unit root test or not.
Moreover segmented trends and structural breaks (see Perron, 1989; Zivot and Andrews, 1992) are not considered in
this analysis as it considered beyond the scope of this study. The possible existence of structural breaks in the series
is neglected because neither fundamental abrupt changes in economic policy nor tremendous exogenous shocks
could be detected in the period of 1989-2009.
47
The inclusion of province-specific effects may not resolve all the possible complications
associated with panel data. In order to produce optimal results, the estimation method largely
depends on the structure of the error process which usually tends to be non-spherical. Three post-
estimation tests are carried out to find the properties of the error structure. The Wooldridge
(2002) AR (1) serial correlation test under the null hypothesis that the residuals in the specified
model do not exhibit first order serial correlation within the panels is applied. The results
indicate that at significance level of five percent the null hypothesis could be rejected in five of
the models.25
Also in this study of disaggregated expenditures it is likely that large errors in one program
spending may be associated with the errors in the other categories in the same year. And with
each province having different endowments and social characteristics, such contemporaneous
correlation may differ by province. Using Modified Breuch–Pagan LM test of independence, the
null hypothesis that the residual across panels are contemporaneously not correlated was rejected
in the entire six models, suggesting the presence of spatial correlation.26
A modified version of a Wald test was conducted to assess if the variances of the error structure
differ from unit to unit. The null hypothesis is rejected, suggesting the presence of groupwise
25
The Wooldridge AR(1) test results for three specification under the median voter model are: (Education: F (1,
20)= 3.607, prob > F = 0.0521; Health: F (1, 20)= 5.885, prob > F = 0.0249; Municipal Services F (1, 20)= 3.163,
prob > F = 0. 0905). The results for the three models under the political budget cycles are: (Education: F (1, 20)=
2.477, prob > F = 0.1312; Health: F(1, 20)= 24.443, prob > F = 0.0001; Municipal Services F(1, 20)= 5.245, prob >
F = 0.0330). 26
The Breusch –Pagan LM test of independence results for the three models under median voter model are:
(Education: Chi2 (45) = 72.608, prob > Chi2 = 0.00057; Health: Chi2 (45) =107.760, prob > Chi2 = 0.0000
Municipal Services: Chi2 (45) = 146.578, prob > Chi2 = 0.0000). The results for the three model under political
budget cycles are: (Education: Chi2 (45) = 170.703, prob > Chi2 = 0.0000; Health: Chi2(45) = 501.606, prob >
Chi2 = 0.0000 Municipal Services : Chi2(45) = 179.241, prob > Chi2 = 0.0000)
48
heteroscedasciticy.27
When these errors complications are not accounted for in the estimation
procedure the results produced tend not be consistent and efficient. Another important diagnostic
that has the tendency to affect the standard errors of the estimates and also provide imprecise
estimates of the marginal effects of the explanatory variables leading to wrong inference is the
presence of multicollinearity. In this study, the correlation matrix and the Variance Inflation
Factor (VIF) of the explanatory variables were examined to determine the degree of collinearity.
Applying the common rule of thumb for the Variance Inflation Factor found in the literature
where VIF of up to 10 is considered not to be a problem statistically, the results show no
evidence of multicollinearity as a problem.
In estimating the equations of the median model, the gini coefficient and the tax-price indexes
are not included in the model simultaneously. This is because the tax-price is presumably
endogenous to the level of inequality in the society. For example, a very unequal society may
choose to rely on a highly progressive tax structure to address redistributive concerns. Thus the
tax-price is a function of inequality. Hence if the Gini coefficient is contained in the regression,
the tax-price is omitted.
Specifications (3.1b) to (3.3b) and (3.1c) to (3.3c) are standard dynamic panel models. By
construction the lagged dependent variable in each equation is correlated with its respective error
term even if the structure of the error term is not serially correlated. The endogeneity caused by
27
The modified Wald test has a null hypothesis of common error variance across all units. The results under the
median model is given by: (Education: Chi2 (21) = 1139.39, prob > Chi2 = 0.0000; Health: Chi2 (21) = 1791.48,
prob > Chi2 = 0.0000; Municipal Services: Chi2 (21) = 131.79, prob > Chi2 = 0.0000. Similarly, the result under the
three political budget cycles models are: (Education: Chi2 (21) = 106.06, prob > Chi2 = 0.0000; Health: Chi2 (21) =
1791.48, prob > Chi2 = 0.0000; Municipal Services: Chi2 (21) = 95.50, prob > Chi2 = 0.0000.
49
the inclusion of the lagged dependent variable implies that estimating the six equations with
Ordinary Least Squares renders the estimates biased and inconsistent. According to Baltagi
(1995) and Kiviet (1995), even estimating the equations with the standard panel estimators like
“within group” or Least Squares dummy variables transformation to remove the individual
effects produces biased and inconsistent results because the correlation remains between
transformed lagged dependent variables and the transformed error terms. The asymptotic
properties of these estimators suggest that as the time period increases, the effects of such bias
becomes minimal. According to (Nickell, 1998) the bias is of order
. This thesis did not
employ such estimation methods because the time period of 21-years involved in this study is
arguably small to overcome the bias.
To overcome these econometric challenges, the estimation method adopted involves two steps.
First, the static versions of (3.1b) to (3.3b) and (3.1c) to (3.3c) are estimated using Feasible
Generalized Least Squares with Fixed Effects (FGLS-FE) designed by Park (1967) and Kmenta
(1986) purposefully for time series cross-sectional data. The Parks-Kmenta method has the
potential to address group-wise heteroskedascity, first-order serial correlation and spatial
dependence in the residuals as the characteristic of the data set in this study. The individual
dummies are included to cater for province-specific heterogeneity. Table 4.1 shows the
estimation results for equations (3.1b) to (3.3b) without the gini coefficient as an explanatory
variable and table 4.2 shows the results with the gini coefficient as an explanatory variable but
without the tax price indexes.
50
In the second stage, the full version of the model is estimated by adopting the Generalized
Method of Moments (GMM) estimator developed for dynamic panel data by Arellano and Bond
(1991). This estimator has the ability to control the effect caused by the unobserved province-
specific effects as well as the bias caused by the right-hand side endogenous variables using
further lags. The standard errors are adjusted for clustering on province. Tables 4.3 and 4.4 show
the results for equations (3.1b) to (3.3b) from the GMM estimation technique. The estimation
method for equations (3.1c) to (3.3c), the political budget cycle models, are the same as the
methods described above for the median voter models. The static versions of (3.1c) to (3.3c) are
estimated first with FGLS estimator followed by the dynamic version with GMM estimator. The
results are presented in tables 4.5 and 4.6
The results from the static and dynamic estimation methods are not necessarily expected to be
the same. This is because theoretically, FGLS is designed for panel data with longer periods
relative to cross-sectional unit while GMM is the opposite. Moreover the inclusion of the lag
dependent variable can suppress the explanatory power of the other independent variables
(Achen, 2001). The main purpose for the second estimation method is just to find out the
dynamics in the adjustments and the degree of persistence in governments spending. Therefore,
the GMM results must be interpreted with care and I stand by the more conservative estimates of
FGLS.

Chapter 4: Results and Policy Implications
This chapter presents the results and policy implications of provincial governments’ expenditures
on health, education and municipal services examined under the two hypotheses. The results of
median voter models are discussed first followed by the political budget cycle models.
4.1 Results and Policy Implications of the Median Voter Model
Table 4.1 shows the regression results for provincial government’s expenditure on health,
education and municipal services from the median voter model perspective. The results are
equation-by-equation estimation of the static version of models (3.1b) to (3.3b) using feasible
generalized least squares estimator with fixed effect (FGLS-FE). The Chi-Square value of Wald
test statistic indicates that all the three models are correctly specified.
The results show that within the period 1989-2009, provincial governments’ expenditures on
health care and education have been driven by the level of real median income. Real median
income has, as expected, a positive coefficient for all the spending categories and is statistically
significant at 1% level in both the health and education equations. A percentage rise in income of
the median voter on average causes provincial government real per capita expenditure on health
and education to increase by approximately 0.30% and 0.37% respectively. These coefficients
indicate that provincial government expenditures on these programs are income inelastic. The
two programs are considered as a normal good (specifically as a necessity and not a luxury) by
provincial governments. Median income does not significantly explain the changes in
government spending on municipal services.
Consistent with the economic theory, the effect of price on government spending captured by tax
price indexes is negative for all the spending programs. The implication is that as the costs of
52
these programs rise the median voter becomes less inclined to demand more of these services.
This leads to a decline in provincial government expenditures on these programs. The estimated
coefficient for the tax-price of health is significant at the 5% significance level. The tax-price of
municipal services is also statistically significant at 1% significance level. A percentage rise in
the tax-price of health care leads to 0.11% fall in the per capita health expenditure and a
percentage increase in the price of municipal services leads to 0.26% decrease in municipal
services spending. The estimated coefficient for the price of education is not statistically
significant.
Population density which may also indicate the degree of urbanisation has a positive relationship
with education and health care spending but it is negatively associated with municipal services
spending. The estimated coefficient is statistically significant at 1% level for both education and
municipal services expenditures. This suggests that as the population of a province increases
relative to a fixed land mass, the per capita expenditure on education increases while municipal
services spending falls. The negative coefficient for municipal services may result from the fact
that provinces with large populations relative to a fixed land mass presents lower average costs
for the government to provide these services. Governments in these provinces may explore the
advantages of economies scale in providing these services. Economies of scale may be enjoyed
by provincial governments in producing these services at least up to the congestion level where
the average and marginal costs will start rising.
The effects of the three age groups on provincial governments’ spending are varied and the sign
of estimated coefficients depend on the type of program. The proportion of children under five
years is negatively related to health spending but the estimated coefficient is positive in both
education and municipal services equations. The estimated coefficient is statistically significant
53
at the 5% level for both health and municipal services spending and at 10% level for education
expenditure. This suggests that as the number of children under five years relative to the total
population increases, it leads to a fall in provincial government health spending, but expenditures
on education and municipal services increase. Similarly as the number of school going age
increases with respect to the total population, per-capita government expenditure on education,
health and municipal services decrease. The estimated coefficient for the proportion of school
going age is negative and statistically significant at 1% level in all the three equations. The
parameter estimate for the proportion of elderly population is positive and statistically significant
for health spending at 10% significance level. However the estimated coefficient for the elderly
cohort is negative and statistically significant at 5% level for education and at 1% level for
municipal services spending.
The positive coefficient estimate for the proportion of elderly in the health spending equation
confirms the popular expectation that the ageing population significantly drives up health
spending. The evidence suggests that within the study period, a percentage rise in the proportion
of elderly above 65 years increases per capita spending on health by almost 0.29%. The negative
effects of the ageing population on education and municipal services can be explained in the
context of the median voter theorem. If the elderly becomes the median voter, they will vote for
programs that are directly related to the elderly like social security and health care as against
education. This is likely to happen if education happens to compete against the other programs
for the same budget share.
The negative links between proportion of school going age and education spending and the
children below five years and health spending may be as a result of economies of scale exploit
by provincial governments in delivering health care services and education to these age groups.
54
Table 4.2 shows the regression results for the three spending categories when the gini coefficient,
a measure of income inequality, is included as an explanatory variable instead of a tax-price
measure. The gini index has a positive association with all the three spending programs and is
statistically significant at 10% level for education spending and 1% level for municipal services
expenditure. This implies that as the level of income inequality increases provincial governments
spend more on education and municipal services. The possible explanation might be that as the
level of inequality increases, the median voter exerts political pressure on the government for a
redistributive government intervention. In this case education and municipal services can be
interpreted to be redistributive government programs.
The other explanatory variables that were statistically significant in the previous models (see
table 4.1) are still significant and have maintained their signs. However, with inclusion of the
gini index the magnitude of the estimated coefficients show slight variation. For instance, in the
health equation the estimated coefficient of the median income has decreased from 0.30 in the
previous model to 0.27 but they are both statistically significant at 1% significance level.
Tables 4.3 shows the regression results of the dynamic version of equations (3.1b) to (3.3b)
estimated using generalized method of moment. Table 4.4 presents the regression results of these
equations when the tax-price variable is replaced with the gini index. In both cases, the lag
dependent variables in the three spending equations are all positive but are statistically
significant at 1% level for only the health and municipal services expenditures. The implication
is that previous period expenditures contribute to the adjustment process in the level of current
spending for these two programs spending. In the education equation (the model with tax price as
55
an explanatory variable but no gini index) the inclusion of the lagged dependent variable has
eroded the explanatory power of population density, proportion of children and elderly variables.
Also, with the inclusion of the lagged dependent variable, generally the standard errors have
increased leading to a reduction in the significance level.
Since various governments’ programs expenditure appropriation is made from the composite
budget it is expected that the unobserved characteristics may affect all the equations. Therefore,
the error terms across the system of equations is expected to be correlated. This is tested using
Breusch-Pagan (1989) specification test of whether or not the residuals from the pooled cross
section, time series regression is correlated across the fiscal variables. The result shows that the
errors across the system of equations are contemporaneously correlated.28
This means estimating
the system of equations simultaneously induces some efficiency gains. Following that, equations
(3.1b) to (3.3b) are estimated simultaneously using seemingly unrelated regression (SUR). The
results are presented in tables 4.7 and 4.8. These results are not discussed but are included for the
purpose of comparing to the results of other studies that use Ordinary Least Squares (OLS) as the
estimation method.
The results of this thesis for the median voter model compare favorably with the results of some
other studies. Stuart et al. (2006) uses a panel of province-level data from 1989 to 2003 to test
the hypothesis that health spending has crowded out other types of spending. They found that the
coefficients of the income variable (personal income) in the health and education equations to be
positive, but only the coefficient in the education equation was statistically significant. Both
children under five years and the elderly population are found to be negatively associated with
28
The Breusch-Pagan test has the null hypothesis the residuals across the equations are independent. The result is given by Chi2 (3) = 29.270, prob > Chi2 = 0.0000
56
health spending but positive with education. Di Matteo (2004) also found income to as a
significant determinant of provincial health spending. The study uses Canadian provincial data
from 1975 to 2000. However the measure of his income variable is real GDP per capita. He
found the proportion of the population aged 65 and above to be positive and significant
determinant of health spending. The negative association between the expenditure on education
and the proportion of school going age population has been by some authors like Strawczynski
and Zeira (2003) for Israel; Medeiros and Barcelos (2007) for Brazilian municipalities and
Fernandez and Rogerson (2001) for US states.
4.2 Results and Policy Implications of the Political Budget Cycles
Table 4.5 shows the regression results for growth in real per capita health, education and
municipal services expenditures examined under the political budget cycles model.
Health care and municipal services spending respond positively to changes in unemployment rate
and GDP growth, while education spending responds negatively to the changes GDP growth.
The provincial government expenditures on these spending programs rise as the level of
unemployment increases. The coefficient estimate is statistically significant at 1% level for
municipal services and education spending. The estimated coefficient for the employment rate is
not statistically significant in the health spending equation.
The proportion of votes and percentage of seats won by the incumbent government, which
measure the size and the popularity of the incumbent government have different effects on
different spending components. The “proportion of votes” is positively related to health
spending. The estimated coefficient is statistically significant at the 5% level. However, the
57
proportion of votes won the incumbent has no significant effects on education and municipal
spending. The percentage of seats won by the incumbent government is negatively correlated
with all the three spending programs but it significantly explains only the changes in health
spending at 1% significance level. This suggests that as the government becomes more popular,
the per capita amount of resources devoted to health and municipal services also increases. On
the contrary, as the number of seats of the incumbent party increases, the growth in health,
education and municipal services spending decline. The possible reason may be that as the size
of the government increases, it feels more secured and becomes complacent.
Incumbent government assuming office for the first term devotes higher resources to education
and health care than “continuity government”. The coefficient estimate for first term incumbent
government is positive and statistically significant at 10% significance level in the health
equation. First term government needs to win the confidence of the people in order to get a
second term. This is usually achieved by honouring the various campaign promises. Health care
and education are core programs most politicians promote during campaigns and therefore it
normal to expect that first term governments will devote more resource for these programs.
Governments whose ideological perspectives are located at left-of-center on the political
spectrum spend more on health care and education than the right-of-center governments. The
estimated coefficient is statistically significant at 1% significance level for health spending. The
dummy variable capturing the effect of minority government on the three spending programs is
positive in all the spending equations. However the estimated coefficient is statistically
significant at 1% level for health and at 5% for municipal services expenditures. This implies
that minority governments spend more on health, education and municipal services than majority
governments. Minority governments rely on the support of other parties to remain in office.
58
Hence minority government can easily be held accountable for the campaign promises and may
also be compelled to implement programs that benefit the majority of the voting populace. This
is likely to result in higher spending on these core programs.
The main variable of interest, election dummy, which captures the effect elections have on
provincial health care, education and municipal services expenditures, is positive in all the
spending equations. The coefficient estimate for the election dummy variable is statistically
significant at 10% level for health spending and at 5% level for municipal services spending.
This means election-years observe a rise in the amount of resource devoted to heath care and
municipal services. Although the coefficient estimate for education is positive, it is not
statistically significant. The joint F-test of the province specific effect is not statistically
significant hence they are not reported.
Table 4.6 shows the regression results when these three equations are estimated as dynamic
panel model with generalized method of moment estimation method. The estimated coefficients
for the lagged health and education are both negative and statistically significant at 1%.
However, the inclusion of lagged dependent variables as additional predictor variables has
absorbed the explanatory power of the main predictor variable, election dummy.
These empirical results are consistent with Rogoff’s (1990) theoretical argument that suggests
that incumbent governments may signal their competence prior to elections by increasing
expenditures on “readily visible” programs without necessarily altering the aggregate
expenditure. Health, education and municipal services are core programs and increasing the
amount of resource in these areas can easily be seen and felt by the electorates in election years.
However the approach used in this does not fully test the Rogoff’s(1990) model. It cannot be
59
established from these results that expenditures on capital projects were reduced giving rise to
the increase in these programs’ expenditures as all programs spending could increase
simultaneously. Such analysis is left for future research.
Kneebone and McKenzie (2001) use a panel data from 1966-1997 on the 10 Canadian provinces
to test the opportunistic responses to spending on various governments programs. They found
that there are higher chances for spending on Education, Transportation and Communication and
Recreation and Culture to increase in election-years. Health, Social Services and Industrial
development are found to decrease in election-years. These results found for education and
municipal services are consistent with the one found in this study where spending on education,
health and municipal services all increase during the election years. It is not surprising that the
results found on health care contradict their finding. This is because the two studies use different
time periods and provincial health care spending and its financing have changed in last few
years.
4.3 Robustness Checks and Extensions
Provincial government spending decisions are sometimes influenced by the level of federal
government transfer payments to the provinces as well as the government’s debt which reflects
the level of borrowing. The federal transfers are made up of two components: the specific
purpose transfers which comprises Canada Health Transfer (CHT) and Canada Social Transfer
(CST) and the general purpose transfers. In the original models estimated to test both the median
and political budget cycle hypotheses, federal transfers and provincial governments’ debts were
not included.
60
The underlying assumption for not including government’s debt was that increases in provincial
governments spending through borrowing would be captured by the tax-price index. However,
governments’ debts via borrowing generally represent future tax increases. Hence the expected
future taxes should have been included in the model to capture the effect of government
borrowing. However, expected future tax variable is not available, hence provincial government
debt servicing cost is used as a proxy.
Similarly, in the original median voter models, the effect of federal transfers to provincial
governments was expected to be captured by the after-tax median income as such transfers
relieves provincial governments from using taxes to pay for their expenditures, which may
translate into higher after-tax median income. Although this may generally hold, it may not
always be true. Federal transfers for health and social welfare may influence provincial
government spending patterns. To check this, both federal transfers and provincial government
debt servicing costs are included in the two models (median voter and political budget cycle) as
an additional control variable. In the median voter models both transfers and government debt
servicing costs are measured in real per capita terms while in the political budget cycle models
they are measured in growth rates.
Also, in the original median voter models, only the program’s own price effects were estimated.
The underlying assumption was that the demand for one good is independent in demand of one
another: they are neither substitutes nor complements. However the processes involved in
government’s budget appropriations suggest that an increase in the price of one good may affect
the expenditure of the other. To check this, cross-price elasticities of demand among the various
programs are estimated.
61
Table 4.9 shows the results when federal transfer and debt servicing costs are introduced into the
median models with the gini coefficient, while Table 4.10 shows the results of these two
variables with the tax-price. Table 4.11 is the results of the political budget cycle models with
these two additional control variables. Also, in these tables are social services spending, another
expenditure category. Expenditures on social services are quite different from the other
expenditure categories as it mostly represents transfer payments to individuals. Political support
for transfer payments to lower income individuals must be motivated by altruism. A median
voter model with altruism is, however, unlikely to be coherent, as the single-peak requirement of
utility as a function of income is violated. For this reason, the original models of the median
voter left out social services.
In the median voter models, federal transfers are statistically significant in both the health and
education equations. As expected, in both equations it has a positive sign. This suggests that an
increase in federal transfer payments to provincial governments, generally leads to an increase in
provincial government spending on these programs. Although the effect of federal transfers on
both municipal services and social services expenditures are positive, the effects are not
statistically significant.
In table 4.10, the results show that the level of provincial government debt is negatively related
to all expenditure categories except social services. The coefficient estimates are statistically
significant for only municipal and social services expenditures. Thus, a rise in provincial
government debt leads to a cut in almost all program expenditures. These results reflect what
happened in the late 1990’s as provincial governments budgetary choices were constrained with
rising debt. The estimated coefficients of the median income variable in both tables are negative
62
for social services spending.29
This shows that as the income level decreases government
spending on social services rises. The results make sense as most of these expenditures represent
redistributive transfer. Also, the estimated coefficient for the cross-price elasticity is statistically
significant and positive between education and health but significant and negative between
municipal services and social services30
. This implies that increases in the price of health care
causes municipal services and social services expenditures to fall, while increases in the price of
municipal services lead to a fall in health spending.
In the context of the political budget cycle models, the estimated coefficients for federal transfers
are statistically significant for education and health expenditures and both have a positive sign.
This shows that increases in federal transfers lead to growth in health and education spending.
However, growth in government debt has a significant and negative impact on municipal
services spending, which suggest that provincial governments cut its spending on municipal
services as its debt level increases. All the other coefficients maintained their signs as in the
previous models, except the election dummy variable measuring the effect of elections on health
care spending. It is now insignificant although it has maintained its positive sign. It seems the
effect is absorbed by the federal transfer variable. This raises a question of whether transfer to
provincial government purposely for health care increases significantly in the election years of
that province?
29
Since federal transfers are included in the models, the before-tax median income of individual is used instead of
after-tax income. Federal transfers, debt servicing costs and social services expenditures are taken from CANSIM
table 385-0002 30
The tax-price of social services is calculated similar to the other programs. However the relative price of social
services component of the tax-price is given by the ratio of GDP price index on general government expenditures on
goods and services to the overall implicit GDP price index. The GDP price index taken from CANSIM
table 384-0036.

Chapter 5: Conclusion
The expenditure levels of various governments programs have been increasing in recent years.
This has been a major source of concern for both policy makers and researchers. To better
understand the driving forces behind these programs spending, much attention has been focussed
on getting a better understanding of the factors that go into the public spending decision-making
process. As a result many theories have been developed to explain the determinants of
government spending on goods and services. This thesis applies two of those theories: the
median voter and political budget cycle models to analyze the drivers of the provincial
governments’ health care, education and municipal services expenditures. Disaggregated data
from 1989-2009 on these three spending programs as well as political variables from the
Canadian provincial governments are used in this thesis.
In the context of the median voter model, it is generally argued that government expenditures on
goods and services are driven by the preferences of the median voter. When the determinants of
the median voters’ demand of a particular good or service change, it may induce a corresponding
change in government spending on that program. The hypothesis that government spending on
these three programs respond to changes in some economic, social and demographic factors that
represent the preferences of the median voter is tested. Specifically, the impact of median
income, tax-price, gini coefficient, population density and age cohort on the three spending
categories are examined.
In the context of political budget cycle models, Rogoff (1990) argues that incumbent
governments may signal their competence during an election year without changing the overall
level of the budget. Incumbent government can achieve this by shifting spending from capital
projects which takes longer period to be observed by the electorates to “readily visible
64
programs”. These three core programs are tested to assess whether its expenditures exhibit
fluctuations induced by elections.
The model specification employed in this thesis is a dynamic model in the form of a one-way
error components model. The estimation method adopted is in two steps. First, a static version of
the full model is estimated with Parks-Kmenta’s Feasible Generalized Least Squares (FGLS)
method. This method is designed purposefully for panel data with more time periods than cross
sectional units as in the case of this study. It also has the ability to control for cross-sectional
dependence of the error term, autocorrelation and heteroskedascity. In the second stage of the
estimation process, the full version of the model is estimated with Generalized Method of
Moment estimation method by Arrelano and Bond (1991).
The findings are generally consistent with the results found in the international literature with
regards to the signs and the level of significance of the key explanatory variables.
The main results from the analysis suggest that: Real median income is a positive and significant
determinant of provincial governments’ expenditures on health and education. The income
elasticities computed show that provincial governments regard education and health care as a
normal good. The tax-price variable is inversely related to health care and municipal services
spending, with the estimated coefficient being statistically significant in both equations. The tax-
price of education does not significantly explain the changes in provincial government
expenditure on education. Increases in the level of inequality contribute positively to an increase
government spending on municipal services and education but does not significantly explain
health care expenditure.
65
There is positive association between population density and the amount of resources provincial
governments devote to health care and education. However, provincial governments exploit
economies of scale in terms of its per capita spending on municipal services as the estimated
coefficient for population density is negative. The effects of the age groups on the government
expenditure are program-specific. The proportion of the elderly population is positively
associated with health spending but its impacts on both education and municipal services
expenditures is negative. The proportions of children under five years is has a positive link with
education spending but inversely related to health and municipal services expenditures. The
school going age population was found to be negatively correlated with all the three spending
categories.
The results from the political budget cycle model show that: The marginal effect of elections on
health care and municipal services expenditure is positive and statistically significant. Although,
there is positive correlation between education spending and elections, the link is not statistically
significant.
Minority governments are significantly associated with higher spending on health, education and
municipal services. First term incumbent governments are noted for higher spending on health
and education than continuous government. Moreover, there is tendency for the per capita
resource devoted for all spending components to increase if the government in office finds its
ideological position located in the left-of-center political spectrum. The popularity of the
incumbent government does not significantly explain the changes in any of spending
components. However, as the number of seats of the incumbents increase it negatively affects its
spending on education and health.
66
The main econometric challenge encountered in this research has to do with finding an estimator
equivalent to the Parks-Kmenta’ estimator specifically designed for dynamic panel model with
more time periods than cross sectional units. The common estimators like GMM, 2SLS, OLS all
rely on some asymptotic properties. Theoretically, GMM is designed for panel data with more
cross sectional unit than time periods. The lack such an estimator makes it difficult to directly
compare the results of the dynamic model to the static model.
