Abstract
We develop a model to study the relationship between participation in free trade agreements (FTAs) and
the sustainability of democracy. We find that, because of the rent-destructing effect of FTAs, they can help
democracy to “consolidate” in a country. If authoritarian groups seek power largely to appropriate rents, an FTA
reduces their incentives to do so, increasing the likelihood that democracy will endure in the country. In turn, this
implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country in
FTAs: to strengthen democracy and, if a democratic reversal seems inevitable, to constrain the rent-seeking
activities of future autocrats. In a dataset with 133 countries over 1948-2007, we find strong empirical support for
our theoretical predictions.

1. INTRODUCTION
Over 200 free trade agreements have been formed since the early 1990s, according to the
World Trade organization. This is also the period where the “third wave of democratization,” as
defined in the political science literature (see Huntington 1991), has taken place. We argue that these
two phenomena, depicted in Figure 1, are not independent from each other. Specifically, we claim
that participation in free trade agreements (FTAs) serves as a commitment device to destroy future
protectionist rents. Since such rents are attractive for autocratic groups, FTAs lower their incentives
to seek power. While this has little value in established democracies, where the rule of law is strong
and the risk of authoritarian disruption is negligible, it can be of great importance for new, unstable
democracies. Trade gains (or losses) aside, these threatened states should therefore be particularly
keen to seek involvement in FTAs. This can help to explain the seemingly puzzling outbreak of
regionalism since the early 1990s, while also helping to rationalize the third democratic wave.
We are not the first to claim that participation in trade agreements is correlated to being
democratic, but to our knowledge we are the first to rationalize, and qualify, this relationship.
Policymakers, for example, often cite political factors such as the “strengthening of democracy” as a
central force behind integration initiatives.1 While it is generally difficult to distinguish true
intentions from rhetoric, political scientists evaluating this issue empirically have indeed found a
positive correlation between participation in FTAs and democracy.2 What is missing is a theory that
allows us to understand this relationship better and test it appropriately. It could be, for example,
that other factors induce countries to form FTAs and to become democratic, but causality does not
follow. In contrast, it could be that FTA participation induces countries to become democratic, or
vice-versa. Clearly, a theoretical model is necessary to guide an empirical evaluation of this
relationship.
We provide this theoretical basis by extending the regional integration model developed by
Ornelas (2005) to allow for endogenous changes in the political regime. In that otherwise standard
model, at any trade regime domestic firms exchange protection for contributions with the
1 For instance, in the 2001 summit congregating the potential signatories of the Free Trade Area of the
Americas, “President Bush said striking down trade barriers was critical to sustaining democracy […] throughout the region” (New York Times, 4/18/2001). To the extent that can be inferred from public speeches, the other region’s leaders shared a very similar view. Similarly, the demand of Eastern and Central European countries for membership in the European Union has often been linked to the countries’ democratic concerns.
2 For example, Mansfield, Milner and Rosendorff (2003) find that pairs of democratic countries are more likely to create trade agreements than pairs in which at least one country has an authoritarian political regime. Mansfield, Milner and Pevehouse (2008) show further that this holds for different types of trade agreements except the “shallowest” ones, according to their five-tier classification. Conversely, Pevehouse (2002) finds that participation in international organizations (which include mainly free trade agreements but also other international organizations) tends to increase the longevity of new democracies.

government, which cares about national welfare and the contributions it receives. A similar game
takes place at the ex ante stage, when the government defines the trade regime—whether or not to
form an FTA. Key to understand the impact of an FTA is the recognition that the equilibrium of the
(ex post) external tariff game changes with the constraint imposed by the agreement on the internal
tariffs. Taking this into account, the main message that arises from the analysis is that, even though
an FTA still permits lobbying for protection against excluded countries, the volume of protectionist
rents falls with the formation of the agreement. As a result, only arrangements that improve welfare
enough to compensate for the lower rents are politically viable.
In a dynamic setting this implies that, all else equal, groups motivated mainly by office rents
will have lower incentives to seek power if the country is engaged in an FTA (and withdrawal from
the agreement is costly). Motivated by empirical findings from the received literature, we consider
that authoritarian groups tend to fit this description best.3 This is also plausible theoretically. After
all, due to the aptitude of authoritarian administrations to resort to violence rather than to rely on
accountability to keep power, their incentives to pursue policies that favor the population at large
tend to be lower than they would be under a democratic administration.4 But if the gain of
authoritarian groups from keeping power are lower if the country is engaged in an FTA, while the
costs and risks from attempting a coup d’état are unaltered by the agreement, the likelihood of
democratic failure will, all else being equal, be lower if the country participates in an FTA.
Now, if the incumbent government in an unstable democracy realizes this effect of
“democratic consolidation,” it will tend to seek participation in FTAs more actively than it would
otherwise. The reason is two-fold. First, the FTA will weaken the authoritarian threat. Second, even
if the dictatorial group takes control despite the FTA, the agreement will constrain its rent-extraction
activities. Hence, unstable democracies will tend to enter in FTAs more frequently than other
countries, all else being equal. In turn, participation in FTAs will tend to increase the likelihood of
democracy survival in those countries.
3 Nalin and Torstensson (1995) find that dictatorships are more likely than democracies to pursue
distortionary redistributive policies. Specifically to trade policies, Banerji and Ghanem (1997), Mansfield, Milner and Rosendorff (2000) and Rama (1994) present evidence that authoritarian regimes are associated with increased trade protection and trade regulations. Mitra, Thomakos and Ulubasogly (2002), estimating welfare and contributions’ weights for Turkey in periods of both democratic and authoritarian administrations, provide additional support for the presumption that, relative to special interests, welfare concerns are more important for democracies than for dictatorships. In a recent paper, Aidt and Gassebner (2008) find evidence of more protectionist policies in autocratic states with respect to both formal (tariffs) and informal (‘red tape’) trade policies.
4 See for example Dixit (2008) for an equivalent assumption, which he uses when analyzing differences in the policymaking process under autocracy and democracy when rulers have to rely on bureaucrats to implement policies.

We look for, and find, empirical support for our theoretical results by analyzing the
formation of FTAs and the strength of democracy in 133 countries over 1948-2007. On the one hand,
we find that greater participation in FTAs lowers the likelihood of democratic failure in a country.
On the other hand, we find that a high risk of democratic breakdown induces countries to
participate in more FTAs. Our findings are robust to different measures of FTAs and the
consideration of endogeneity.
Interestingly, the predictions hold well for full-fledged FTA and customs unions, signed
according to the GATT Article XXIV. When partial-scope preferential trade agreements (PTAs) are
included, the results remain significant in most cases but are usually somewhat weaker. This is what
we would expect, as those PTAs, signed under the Enabling Clause of the GATT, allow for many
exceptions in regional trade liberalization.
One of our empirical challenges is to define how unstable a democracy is. We do so by
relying on a recent study by Persson and Tabellini (2009), who estimate the likelihood of democratic
breakdown employing the concept of “democratic capital.” Democratic capital has two components,
one domestic and one foreign. The domestic component takes into account the history of democracy
in the country. The longer the country has experienced democracy, and the more recent is its
democratic experience, the greater the country’s current stock of domestic capital. The concept of
foreign capital encompasses instead current levels of democracy in the rest of the world. The greater
the number of democratic countries, and the closer those democratic nations are to a certain country,
the greater is that country’s current stock of foreign capital. Along with other covariates, these two
components of democratic capital allow us to estimate the likelihood of democratic failure in a
country. In the sense that we find that participating in a greater number of FTAs significantly
reduces this probability, regionalism helps to “consolidate democracies.”
Having estimated the likelihood of democratic failure, we use its fitted values to estimate
entry in/formation of FTAs. In doing so, we consider only the portion of the likelihood that is not
predicted by FTA participation. Our finding that higher levels of regime uncertainty does indeed
induce democratic governments to seek participation in FTAs helps to rationalize the regionalism
wave since the early 1990s, when many countries became democratic but, due to their limited
experience with democracy, faced significantly high levels of political instability.
The paper proceeds as follows. Section 2 describes the model. Section 3 presents the analysis
of the incentives to form a free trade agreement. Section 4 discusses our empirical strategy. The data
is presented in Section 5. We show our results in Section 6. We conclude in Section 7.

2. THE MODEL
2.A. The economic structure
We consider a 3-country, N-sector competitive economy where in each sector there is a
“natural importer” country that would import the good from the other two countries under free
trade. Goods are produced under constant returns to scale. One unit of the numeraire good 0 is
produced with one unit of labor. All other goods j = 1…N – 1 are produced with labor and a sector-
specific factor. Thus, whenever good 0 is produced in equilibrium, which we assume to be the case,
the wage rate equals unity and all general equilibrium forces are absorbed by that sector.
The analysis is conducted from the perspective of a “Home” country. Home’s population
consists of a continuum of agents with measure one. Each agent is endowed with one unit of labor,
whereas specific factors are owned by a negligible fraction of the population. Consumers have
quasi-linear utility of the form [ ]∑−
=−+= 1
1
2 2/)(N
j
jj0 qAqqU , which generates demand D j = A – p j
for good j.
Home is the natural importer of goods m = 1…M, country Y is the natural importer of a
subset E of different goods, and country Z is the natural importer of the remaining (N – M – E – 1)
non-numeraire products. Home’s owners of the specific factor used in sector j earn πj(pj), where pj
denotes the price of good j in Home’s market. The domestic supply of each imported good m is
Sm(pm) = dmpm and the supply of each exported good x is Sx(px) = dxpx, where dx > dm > 0. An
analogous specification applies for the supply and demand structures of countries Y and Z. Home
can use specific import tariffs in each import sector; other policy instruments are assumed
unavailable. We represent Home’s tariff on imports from country j by tj, j = Y, Z. Because all import
sectors are identical, we will write prices and tariffs without sector-identifying superscripts.
Prices in the three countries are linked by arbitrage conditions. For a generic product
imported by Home, this condition is
(1) p = pY + tY = pZ + tZ,
provided that tariffs are not prohibitive. Using this arbitrage condition, market-clearing requires
(2) D(p) – Sm(p) = Sx(p – tY) – D(p – tY) + Sx(p – tZ) – D(p – tZ).
Using the expressions for demand and supplies defined above, condition (2) can be rewritten as
(3) ρ++γ= )(),(ˆ YZYZ ttttp ,
where γ ≡ 3A/(3+dm+2dx) and ρ ≡ (1+dx)/(3+dm+2dx).
When Home is member of a free trade agreement, it follows GATT’s requirement of non-

discrimination. When Home is in an FTA, imports from the FTA partner are duty free, but imports
from the excluded country remain taxed, although the country’s external tariff will change as a
result of the FTA, as we will see.
2.B. The political structure
There is a democratically elected government that rules Home. The group represented in the
government enjoys power because there are rents for holding office. The sources of those rents are
transfers/bribes offered by the private sector, which benefit government officials in exchange for
more favorable policies. Thus, the rents are specific to incumbency, as for example in Besley and
Coate (2001).
The group in power cares also about national welfare. As in the literature of strategic debt
issuance, we consider that a party’s welfare concerns reflect the links with its “constituency.” In
general, the larger the constituency of the elected government, the higher the weight the government
attaches to national welfare, relative to office rents. A direct implication is that a larger constituency
induces the government to internalize a greater share of the distortions created by its policies. This
specification therefore presumes that the welfare concerns of a political group, stemming from the
group’s link with its constituency, are unrelated with incumbency, unlike the transfers obtained
through interactions with the private sector.
Let us define the measures of welfare. Welfare generated in an import sector is denoted by
Wm(t), whereas Wx represents welfare from an export sector. The former is defined as the sum of
consumers’ surplus, tariff revenue and producers’ surplus generate in that sector; the latter is
defined as the sum of consumers’ and producers’ surplus in the sector.5 Welfare aggregated across
all non-numeraire import and export sectors is then WM(t) ≡ MWm(t) and WX ≡ (N - M - 1)Wx,
respectively. National welfare, W(t), aggregates welfare across all sectors:

with Gx ≡ Wx/b and
5 Note that we denote welfare in import-competing sectors as a function of the tariff, but not in export
sectors. In reality, Wx also depends on tariffs, but on those imposed by foreign countries Y and Z. Since those tariffs are given from the perspective of the Home government under any trade regime, we employ this briefer representation for notational ease.

b is a parameter that is inversely related to the size of the constituency of the government. We refer
to b as the “political bias” of the government. Thus, if the government’s constituency were very
small, the government’s political bias would be very high and it would care mainly about rents.
Conversely, if the government’s constituency were very large, the government’s political bias would
be very low and it would largely disregard rents.
We assume producers within each industry can overcome free-riding problems and act
jointly in their lobbying activities. Because of the symmetry and independence across sectors, we
focus on a single import-competing sector. The net payoff of producers in such a sector corresponds
to the industry’s aggregate profits, πm(t), subtracted of the transfers it gives to the local government,
Tm.
As in Maggi and Rodríguez-Clare (1998), we model the interaction between government and
each domestic industry as a Nash bargaining game, where each side obtains half of the total surplus
from the negotiations process. Under the Nash bargaining protocol, the outcome of the bargaining
process is jointly efficient. Thus, the “political tariff” resulting from this interaction satisfies
(6) )]()(max[arg tbtWt mmp π+= ,
where the term in brackets represents (up to a constant) the joint payoff of the government and the
industry in a representative import-competing sector. To simplify exposition, we restrict the analysis
to the case where the solution of problem (6) is interior. This corresponds to assuming that b < bmax ≡
(1+dm)(dx–dm)/(1+dx)dm.
2.C. Equilibrium payoffs
In the absence of lobbying activities, the government can do no better than set the tariff in
each import sector to maximize national welfare. As a result, its payoff in that case would be given
by Wm(tp(b=0))/b, or simply Wm(b=0)/b. Analogously, the domestic industry m would obtain a
payoff of πm(b=0) ≡ πm(tp(b=0)).
We can then define the “political rents” created in the lobbying process in each import-
competing sector as

where functions Wm and πm are evaluated at the political tariff when they are represented as a
function of b. The expression in the first parenthesis of (7) is the maximized joint payoff of the
government and the industry (multiplied by b), while the expression in the second parenthesis is the
value of the same function in the absence of lobbying. The difference between these two expressions
represents the surplus that the lobbying process adds to the joint payoff of the government and the
industry.
In equilibrium, the government obtains its reservation payoff in the industry plus its share of
the political rents:

[WM(b=0) + WX]/b, plus half of the political rents. This makes clear that the group in power does
not internalize the welfare distortions due to its use of the political tariff.
In contrast, if the same political group were out of power, its payoff would be different even
if the tariff were the same. The reason is that the group does not receive any rents if it is not in a
position to enact policies. Accordingly, in that case the group would receive none of the available
political rents, and its equilibrium payoff H would reflect only the concerns for its constituency:

2.D. Coup threat
We consider a simple 2-period environment where there is a group of citizens representing a
segment of the population that is not represented in power but may attempt to take power through
force, initiating a dictatorship in the country. We are not specific about which segment of the
population is represented by this group; it could be the military as well as part of the country’s
capitalists or the upper class, for example. In any case, whenever a coup is attempted and is
successful, the authoritarian group takes power in the second period.
![Page 9: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/9.jpg)

We assume the potential dictatorial group cares predominantly about its own well-being.
That is, rather than considering the potential dictatorship as “benevolent,” as sometimes assumed in
economic analyses, we treat it as “kleptocratic.” Moreover, since the supporting group of a
dictatorship tends to be considerably smaller than that of a democratically elected government, the
forces limiting rent-seeking behavior tend to be weaker in a dictatorship. This suggests that an
autocratic government would attach a higher weight on rents vis-à-vis national welfare than the
democratic government. Accordingly, we consider that
A1: bD ≤ bA,
where we use identifiers D (democratic) and A (autocratic) to distinguish between variables related
to the incumbent democratic government and the authoritarian group, respectively.
We let the probability of success of a coup depend negatively on the country’s stock of
“democratic capital.” The notion of democratic capital (DC) is introduced and developed by Persson
and Tabellini (2009), and corresponds to a measure of the strength of the country’s democratic
institutions. In nations with enduring democratic tradition, where the rule of law is strong,
democratic capital tends to be abundant, virtually precluding the possibility of political disruption.
Conversely, in countries lacking solid institutions, where the rule of law is weak, democratic capital
is likely to be scarce, thus opening a tangible opportunity for successful coups. In the definition of
Persson and Tabellini (2009), an important element shaping the stock of DC in a country is the
country’s democratic history. In fact, as North (1990) points out, the costs of altering political
institutions are very low when they are new, but increase as they get older.
We assume that the precise level of democratic capital is not known with certainty, but its
expected value, ,DC is. Specifically, we define the democratic capital of the Home country as
,= DCDC θ where θ is a random variable with expected value E(θ) = 1 distributed accordingly to
distribution function Φ in the interval [0, 2].
The probability of success of a coup depends also on how the population reacts to the
attempt. In particular, success will be more likely the stronger the “support” of the pro-coup citizens
and the weaker the “resistance” from the segments of the population opposed to the coup. We call
the difference between support and resistance in the population the “net support” for a coup, and
denote it by s. We normalize the units of s and DC so that an attempted coup is successful if and
only if s > DC. Thus, from the perspective of the group considering subverting the country’s
democratic order, the probability of success is
![Page 10: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/10.jpg)
10
(11) p ≡ prob (s ≥ DC) = prob (s/DC ≥ θ) = Φ(s/DC ),
where p denotes the probability of success of the coup.
Both the democratic government and the authoritarian group discount future payoffs
according to a (common) discount factor δ, where δ ∈ [0, 1]. To understand when the authoritarian
group will attempt to subvert the country’s democratic order, we model the group’s problem as
simply as possible. In particular, we assume that, if the takeover attempt is successful, the
authoritarian group imposes a dictatorship in the country and obtains its office payoff GA in the
second period. If the takeover attempt is unsuccessful, the group bears a fixed cost K > 0.6
When a coup is attempted, the present value payoff of the incumbent and of the
authoritarian group are represented, respectively, as
(12) ])[( DDDD pHGpG +−δ+=Γ 1
and
(13) ]))([( AAAA pGKHpH +−−δ+=Γ 1 .
In no coup were attempted, the incumbent government and the authoritarian group receive,
respectively, GD and HA in each period.
The (risk-neutral) authoritarian group attempts to take power if and only if the expected
utility from the endeavor is positive: ΓA > (1 + δ)HA. Using (13), this condition is equivalent to
(14) KpHGp AA )()( −>− 1 .
That is, the authoritarian group will attempt to take power if its expected gain from seeking power is
large relative to the expected cost of a failed coup.
To make explicit what is behind the probability of success of the coup and the gains from
holding office, we use the definition of p and expressions (9) and (10) to rewrite condition (14) as

In a consolidated democracy, where either the support for a coup is very low or democratic capital is
knowingly very high, an attempt against the county’s democratic system is unlikely, unless the costs
of failure are too low—which is rarely the case—or the gains from holding power are very
significant. Our central goal is to analyze how a free trade agreement affects the latter, and through
that channel the endurance of democracy in a country.

Naturally, an FTA can be used to affect future policies only if its reversal is costly enough to
inhibit withdrawal from the arrangement by future governments. While here we simply assume that
FTAs are irreversible, Ornelas (2007) presents a straightforward extension of a similar model where,
paralleling McLaren (2002), governments incur in “negotiating costs” when forming (or
withdrawing from) FTAs. That extension, which treats irreversibility as an equilibrium result, shows
that the rationale developed in this paper requires only the existence of a cost to reverse established
FTAs.7
3. THE DECISION TO FORM A FREE TRADE AGREEMENT
A free trade agreement between two countries is represented by the elimination of tariffs on
each other’s imports. Thus, the equilibrium under an FTA is entirely analogous to the one described
in Section 2, the only difference being the constraint imposed on the partner’s reciprocal import
tariffs. Without loss of generality, we let Home’s potential FTA partner be country Y.
An FTA can be implemented by the incumbent government for reasons related or unrelated
to the authoritarian threat. There are four possibilities. First, it is possible that the country is already
a consolidated democracy, in the sense that condition (15) is not satisfied regardless of the existence
of FTAs. This is the standard case analyzed in the regionalism literature, and it is not our goal to
analyze it further in this paper. Rather, we focus on situations where FTAs are formed for “strategic”
reasons.
Second, it is possible that the country’s democracy is so fragile that condition (15) is satisfied
whether or not there is an FTA in place. In that case, while an FTA cannot be used to prevent a coup,
the possibility of a reversal to a dictatorship can affect the incentives of the incumbent government
with respect to the formation of the agreement.
Finally, it is possible that an FTA affects the expected payoff of the authoritarian group and,
as a result, its incentives to attempt to take power. In general, an FTA could either increase or
decrease the incentives for a coup, making it worth seeking when it would not be without the
agreement or vice-versa, making the coup not worth pursuing when it would be in the absence of
7 It is worth noting that irreversibility is coherent with history, as preferential trading arrangements de facto
implemented are seldom turned down later on. Even in the rare circumstances when authoritarian regimes gained control of a country that participated in an effective trade agreement, the arrangement has been honored, as for example in Swaziland, a member of SACU. The only exception to this rule seems to be the Andean Pact, from which President Hugo Chávez withdraw Venezuela in 2005. The other cases of implemented agreements being later disrupted took place in Central America (CACM) and in the Caribbean (CARIFTA/CARICOM), but in both cases they were disrupted due to balance of payments constraints during the debt crisis of the 1980’s. Both were fully reactivated in the early 1990’s.

the agreement.
We begin analyzing the cases where the FTA is not pivotal for the decision of the
authoritarian group—i.e. when condition (15) is unaffected by the FTA. To do so, we need first to
describe the effects of an FTA on the level of available political rents and the role of the political
parameter b in shaping the welfare effects of an FTA. These results set the basis for the analysis of
the political viability of FTAs.
3.A. The rent destruction effect
Ornelas (2005) shows that an FTA moderates the role of political economy forces in the
determination of tariffs, and that the mitigation of the politically driven distortions corresponds to a
source of welfare gain that is more relevant, the more far-reaching the government’s political
motivations. Furthermore, an FTA diminishes the rents created in the lobbying process. Intuitively,
because the arrangement provides free access to the partner’s exporters, the market share of the
domestic industry shrinks, at any given external tariff. As a result, the FTA makes any price increase
brought by a marginal increase in the external tariff less valuable for the import-competing
industries, lowering their incentives to lobby for higher external tariffs. In equilibrium, these lower
incentives imply less lobbying, a lower external tariff and fewer rents for the government. The
following lemma summarizes these effects.
Lemma 1. The rent destruction effect of FTAs (Ornelas 2005)
Everything else constant, an FTA
(a) improves Home’s welfare by more (or reduces it by less), the higher the government’s
political bias; and
(b) reduces the political rents generated in the political process, this reduction being larger,
the higher the government’s political bias.
Lemma 1 allows us to analyze the conditions under which the Home government would
choose to form an FTA.8 The decision regarding the formation of an FTA is based on the anticipated
impact of the agreement. The government implements the agreement if and only if it increases the
government’s present value payoff.
8 Naturally, an FTA is formed only if all prospective members endorse it. We conduct the discussion from
the perspective of the Home country, but an analogous analysis would apply for country Y.

Before proceeding to analyze how the possibility of political disruption affects the
willingness of the democratic government to form free trade agreements, it is important to note that,
under A1, the authoritarian group will not want to form an FTA if the democratic government has
rejected it. On the other hand, if the authoritarian group is willing to form a certain FTA, the
democratic government will want to do too, strategic motivations notwithstanding. To show this, we
henceforth attach subscript “F” to all variables when they are evaluated under an FTA. We also
adopt subscript “∆F” to represent the equilibrium change in any variable due to the FTA. For
example, XFW∆ denotes the aggregate welfare change in the export sectors due to the agreement,
whereas )( DMF bW∆ and )0=(bW M
F∆ denote, respectively, the aggregate welfare impact of the FTA on
the import sectors under the ruling of the incumbent democratic government and under an
administration whose only concern is national welfare (or equivalently, if lobbying were effectively
banned).
Lemma 2. Strategic considerations aside, if the democratic government does not want to form an
FTA, the authoritarian would not want to form it either. However, if the authoritarian group
would want to implement an FTA, the democratic government wants to implement it, too.
Proof: In the absence of strategic considerations (i.e. if there were no possibility of political
disruption), the democratic government wants to implement an FTA if .0>DFG∆ From (9), this
condition is equivalent to

Similarly, if in power, the authoritarian group would be willing to form the FTA if

Now notice that, under A1, part (b) of Lemma 1 implies that the right-hand side of (17) is greater
than the right-hand side of (16). Therefore, if condition (17) is satisfied, condition (16) is also
satisfied. Conversely, if condition (16) is not satisfied, condition (17) is not satisfied either. �
Since the authoritarian group would not support an agreement that the democratic
government ordinarily rejects, it follows that, if the democratic government decided to back an FTA
only for strategic reasons, the FTA would not be supported by the authoritarian group in case it
gains power (since the authoritarian group has no further strategic motivation once it gains power).
3.B. FTAs that do not affect the probability of political disruption
![Page 14: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/14.jpg)

(21) can satisfy criterion (20) for sufficiently high p. On the other hand, the reverse cannot happen: if
an FTA is politically viable when there is no chance of political disruption, it remains feasible if a
possibility of change in power through force arises. That is, an FTA that satisfies condition (21)
satisfies criterion (20) for any p > 0. �
Proposition 1 shows that the possibility of political disruption can enhance the political
feasibility of FTAs by creating a “strategic” motivation for their adoption. Strategically supported
FTAs arise when, among conditions (20) and (21), only the former is satisfied, so that

An FTA can be implemented for strategic reasons because the democratic government, if out of
power, will not receive any of the lobbying-related rents. In that case, the government would benefit
from an FTA because the agreement constrains the welfare-distorting political activities of the
authoritarian group if it gets in power. Thus, a government that expects to lose power to a dictatorial
group might seek an FTA simply to constrain the policies of the incoming authoritarian group. Since
this strategic motivation is more relevant when disruption is more likely, it follows that “political
instability” tends to incite the formation of free trade agreements.
The political biases of both the incumbent government and of the authoritarian group affect
the possibility of strategically supported FTAs. In particular, higher political biases enlarge the scope
for this type of arrangements. The same is true for the number of Home’s import-competing sectors,
M.
Proposition 2. The set of parameters under which the possibility of political disruption can turn an
FTA politically viable increases with the political biases of the democratic (bD) and the
autocratic (bA) groups, as well as with the size of Home’s import-competing sector (M).
![Page 16: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/16.jpg)

Proof: To prove these results, it suffices to show that the probability of disruption, p, is a strategic
complement of bA, bD and M in the function ,DFDb ∆Γ which gives the criterion for the political
viability of FTAs. This function is represented in the left-hand side of (20). We have that

Hence, the set of parameters under which condition (23) is satisfied enlarges as bA, bD and M

The intuition behind Proposition 2 is as follows. The more biased toward special interests is
the authoritarian group, the larger the distortions it would create if it held power. In that case, the
role of FTAs in moderating distortions and enhancing welfare is magnified (Lemma 1), so a larger bA
makes the incumbent democratic government more inclined to use an FTA to limit the rent-seeking
activities of the potential dictatorship. Now, if the democratic government is itself very receptive to
the politically generated rents, it will in general be sign a rent-destructing FTA. This anti-FTA force
is partially neutralized, however, if the incumbent believes its chance of keeping power is small,
since in that case the loss of rents brought about by the FTA would be born mainly by the
authoritarian group. If the weakening of this effect is sufficiently strong, the incumbent may find it
worthwhile to support the agreement.
Finally, if Home were small relative to its FTA partner, in the sense of having a relatively
large non-numeraire import-competing sector, the incentives of the democratic government to form
the agreement because of the authoritarian threat are greater as well. If Home imports more
intensely from its partner, the agreement is more rent destructing. While this is helpful for the
country as a whole, it is detrimental to those in office who benefit from those rents. Under the threat
of political disruption, however, the government understands that the loss of rents will be borne
![Page 17: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/17.jpg)
17
instead by the authoritarian group, if it is successful in gaining power. The destruction of rents is
therefore less critical in the democratic government’s evaluation of the agreement.
As indicated in the Introduction, the idea that governments can manipulate state variables to
constrain their successors’ choices was first advanced in the macroeconomics political economy
literature. Prominent examples in that line of research are the pioneering contributions of Alesina
and Tabellini (1990) and Persson and Svensson (1989), who employ such a rationale to study the
politics of debt issuance. A similar reasoning is employed here to show that a democratic
government, when faced with the prospect of political disruption, may want to limit the ability of
the potential authoritarian government to create rents through interactions with the domestic
industry. We show that an FTA can be an effective tool for that purpose.
3.C. FTAs that can help secure democracies
The analysis above considers the case where a free trade agreement is not pivotal in the
decision of the authoritarian group to attempt to take power through force. But this need not be the
case. That is, an FTA may change the sign of condition (15). We show that an FTA can indeed change
the sign of condition (15), but the change can go in only one direction. Specifically, an FTA can
prevent a coup from happening, but it cannot provoke a coup that would not occur in the absence of
the agreement.
Proposition 3. If the authoritarian group does not intend to initiate a coup in the absence of trade
agreements, an FTA cannot induce it to initiate one. On the other hand, the formation of a
sufficiently rent destructing FTA can free the country from the authoritarian threat. This is
more likely to happen, the greater the political bias of the democratic government (bD) and
the size of Home’s non-numeraire import-competing sector (M).
Proof: In the absence of trade agreements, the authoritarian group attempts to take power with a
coup if condition (15) is satisfied. With an FTA, a similar condition applies:

which denote the gains of the authoritarian group from getting power. On the other hand, the FTA
impacts neither the probability of success of a coup nor the costs of a failed coup attempt.
Subtracting the left-hand side of inequality (15) from the left-hand side of inequality (24), we obtain
![Page 18: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/18.jpg)

condition (23) will not be satisfied either, implying that an FTA cannot provoke a coup that
otherwise would not occur. Conversely, condition (15) can be satisfied while condition (23) is not,
implying that an FTA can be critical to prevent the authoritarian group from seeking power. The
range of parameters under which this happens is larger, the greater the number of Home’s non-

Proposition 3 shows that, because of the rent destructing effects of FTAs, a free trade
agreement can critically reduce the incentives of the authoritarian group to attempt to subvert the
country’s democratic system. In this sense, an FTA can help to constrain the emergence of
authoritarian regimes, especially if the bloc is significantly rent-destructing, as in that case it will be
more effective in lowering the gains from power of the authoritarian group. Building on the
common notion that the availability of rents can entice political turbulence—while the unavailability
of rents can prevent it10—the proposition’s novelty stems from the recognition of free trade
agreements as instruments to restrain the gains from rent-seeking behavior.
We still need to ask, however, whether the incumbent democratic government would
actually want to implement the arrangement. The next proposition shows that the possibility of
using an FTA to block a coup necessarily raises the government’s political benefits with the
agreement.
Proposition 4. An FTA can become politically feasible by being pivotal to prevent a coup.
10 This is, for example, Olson’s (1993) main message.

Proposition 1 asserts that the possibility of political disruption can render feasible an
otherwise unfeasible free trade agreement. Proposition 4 indicates that the political support for an
FTA can be further enhanced if the agreement can also play a role in preventing disruption of the
political system. This is true even though here we abstract from any ideological motivation the
incumbent democratic government may have; if the government perceived a benefit per se from
maintaining democracy in the country, its incentive to form an FTA that can serve that purpose
would be further enhanced.
The result suggests that free trade agreements—especially those that are particularly
effective in destroying office rents, as those formed with larger trade partners—can be useful to
prevent the breakdown of democracy when the country does not have sufficient democratic capital
to prevent the authoritarian threat. This is often the case in nascent democracies, given the unstable
political periods that typically follow the end of dictatorial regimes. In fact, the establishment of new
democracies has often been followed by the formation of preferential arrangements (or the accession
to existing ones). This was the case, for example, of all Mercosur members, of Greece, Portugal and
Spain in their accession to the European Community, and of the EU agreements with the countries
of Central and Eastern Europe shortly after the fall of the iron curtain. The European Community
was itself established few years after the end of autocrat regimes in some of its original members
(Germany and Italy). Not surprisingly, then, the consolidation of democratic regimes is often

presented as one of the primary goals in the formation of free trade agreements.11 The present
analysis provides a (so far absent) coherent explanation for the link between democratic
consolidation and the establishment of free trade agreements.
4. EMPIRICAL STRATEGY
The model has two main predictions about the relationship between FTAs and democracy,
which imply the following hypotheses:
H1. Participation in FTAs lowers the likelihood of democratic failure.
H2. Unstable democracies are more likely to form FTAs.
To test H1, the dependent variable is the probability that democracy will fail in the country,
which we denote by Prob(enddemo), or the length of democratic spells. The key independent
variable is a measure of the country’s participation in FTAs.
To test H2, the dependent variable is the change in the FTA variable. The key independent
variable is a measure of unsecured democracies, which reflects the expectation that the democratic
regime may fail in the country.
As indicated in the Introduction, our problem is related to the one studied by Persson and
Tabellini (2009), who examine the determinants (in particular the effect of income) of the stability of
democracies and the impact of this perceived stability on income growth. Our empirical strategy
resembles Persson and Tabellini’s approach.
Specifically, we estimate the likelihood of democratic failure relying on the concepts of
domestic democratic capital (DOM) and foreign democratic capital (FOR) developed by Persson and
Tabellini, but adding a variable that captures participation in FTAs. DOM is a measure of the
democratic history of the country, whereas FOR measures current levels of democracy across the
world.12 Other explanatory variables include economic factors (e.g. GDP per capita, denoted by the
vector X) and geographical and institutional factors (e.g. war indicators, continent of location and
legal origin, denoted jointly by the vector Z). With the dependent variable being a dummy
11 As The Economist (4/19/2001) points out with regard to the possible creation of the Free Trade Area of the Americas,
“the elected leaders of Latin America look to the United States as an export market but also as a source of support for democracy in the region.” Similarly, when the United States first announced the intention to pursue a free trade agreement with Central America countries, there were three explicit goals with the agreement, one of which was “to support democracy in the region”—the other two were to promote U.S. exports and to advance the FTAA (www.whitehouse.gov, January 16, 2002).
12 In the next section we provide a precise definition of both variables.
![Page 21: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/21.jpg)
21
indicating whether a democracy was interrupted (enddemo), a discrete time duration analysis such
as logit or complementary loglog (cloglog) can be implemented as follows:13
(27) Prob(enddemo) = α0 + α1FTA-1 + α2DOM-1 + α3FOR-1 + α4X-1 + α5Z-1 + u,
where subscript -1 denotes that the variable is lagged one year.14
The variable FTA in equation (27) represents a measure of the country’s degree of
participation in FTAs in a given year, or the country’s “FTA intensity.”. Measuring the FTA intensity
of a country is a non-trivial task. Most empirical regionalism papers use dummies to represent FTA
participation. While this can be adequate in other studies, such a measure is not appropriate for our
purposes. The reason is that there is wide heterogeneity in FTAs and in the countries participating in
FTAs. First, while some arrangements are fully implemented, others are not, implying few and small
preferences are actually offered. Second, a given FTA can have a very different impact on each of its
members.15 Given this, in all of our main regressions we use the share of imports from FTA
members to represent a country’s FTA intensity. This variable should vary monotonically with the
degree of implementation of the agreement and with the importance of the agreement for the
country in question. It is also a useful proxy for the degree of rent destruction of the FTA, since this
is positively associated with the share of preferential imports. To check for robustness, we also
briefly discuss when using alternative definitions for FTA intensity.
There is a concern about duration dependence in (27). If there is duration dependence, the
hazard of enddemo will depend on the duration of the democratic regime. In principle, its effect can
be either positive or negative. To capture duration dependence, we use a polynomial of a time
counter that counts the number of years passed since the beginning of the current democratic spell.
The order of the polynomial is determined by the best fit in the regressions.
Including this duration polynomial, which we denote by DUR, we rewrite our estimating
equation as
13 When the probability of positive outcomes is small, as in the case of enddemo, where democratic failures
account for only 2% in our dataset (see Table 1), a cloglog link function is similar to a logistic link function. Hence the coefficients obtained from a cloglog regression can be exponentiated and understood in terms of odds ratio. Since logistic regressions are more conventional than cloglog ones, we only report logit results. Results from cloglog regressions are very similar.
14 Some variables, such as geographic variables, legal origin and colony dummies, are constant over time. Therefore it does not matter whether they are lagged or not.
15 Consider for example NAFTA. While it has always had a very large impact on Mexico, the smallest member, its impact is much less pronounced on the United States, the largest member.
![Page 22: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/22.jpg)
22
(28) Prob(enddemo) = α0 + α1FTA-1 + α2DOM-1 + α3FOR-1 + α4X-1 + α5Z + α6DUR + u.
A remaining concern in (28) is unobserved heterogeneity. That is, it is possible that some
countries are more likely to have interrupted democracies due to unobserved variables that are
correlated with some right-hand side variables in (18). To deal with this possibility, we also run a
random effects logit specification.16, 17
Once we have the predicted Prob(enddemo), we can use it to test our second hypothesis, that
the likelihood of democratic failure helps to explain the formation of FTAs. We also include the
economic, geographical and institutional variables used in the duration regression, except DOM and
FOR. Nothing in our theory suggests that DOM and FOR should have an independent effect on
∆FTA in addition to their indirect effects on ∆FTA through Prob(enddemo).18 This is similar to the
identification assumption of Persson and Tabellini (2009), that both components of democratic
capital affect income growth through their effects on the sustainability of democracy only. Some
may argue that the rationale to exclude FOR may not apply here, since FOR could have an
independent effect in the formation of FTAs. For this reason, we will run the ∆FTA regression with
and without FOR to check the robustness of our results.
Note also that the duration dependence terms are included in the prediction of
Prob(enddemo) but will not be included in the second stage ∆FTA regressions, which instead use
year dummies to capture the time effect. As another robustness check, we also try to include all the
regressors from the first stage enddemo regressions in the ∆FTA regression (i..e, without exclusion
variables). In this case, we rely only on the non-linearity of our first stage logit estimation to identify
the predicted hazard in our second stage ∆FTA regression.
To test H2, we then run the following specification, where we include both year dummies
and country fixed effects:19
16 No consistent fixed effect cloglog procedure is available. The fixed effect logit procedure (i.e. conditional
logit) is available but inappropriate because most of the country*spell units of observation do not experience democracy breakdown during our sample period. These observations would be dropped in fixed effect logit regressions, eliminating much of the cross-sectional variation.
17 With “frailty,” as unobserved heterogeneity is denoted in the duration literature, the logistic hazard
function becomes )]exp(1/[1 uXh tijtijt −θ−β′−+= . If we assume a normal distribution for the unobserved
heterogeneity u, we can use a random effects logit specification. 18 In fact, including them in the ∆FTA regressions has only a very small impact on the results once the
predicted Prob(enddemo) is included, with the DOM coefficient being statistically insignificant. 19 Other variables affecting FTA formation could also be included. Interestingly, even though much has been
written about regionalism, we still know little about what makes a government willing to form FTAs. Consider for example the important contribution to this topic by Baier and Bergstrand (2004). A major difference between their paper and ours is the data structure. Their data is bilateral and cross sectional so that each observation is associated

One may be tempted to estimate equations (27) and (29) together as a simultaneous system:
logit for equation (28) and OLS for equation (29). But this method is not applicable. First, the FTA
variable appears in levels in equation (28) but in changes in equation (29). Second, Prob(enddemo) is
unknown in equation (29).20 Therefore, we need to estimate the two equations separately.
Specifically, we replace Prob(enddemo) in equation (29) with its predicted hazard rate ( h ) from
equation (28). Because h is a function of FTAs, we do not use the variable FTA directly in the
estimation of h . Instead, we estimate h from the following regression:
(30) Prob(enddemo) = γ0 + γ2DOM-1 + γ3FOR-1 + γ4X-1 + γ5Z-1 + γ6DUR + e.
Having estimated h , we then use it in equation (29), paralleling the empirical strategy of
Persson and Tabellini (2009). We also include the squared term of h to capture possible
nonlinearities.
4.A. Duration analysis
The duration regression (logit or cloglog) we describe above is a discrete time analysis,
where we treat the time interval as discrete or grouped by year. Alternatively, we also use
continuous time duration analysis for equation (28), defining the dependent variable as the duration
of democracy spells, i.e. the number of years passed since the onset of each democracy spell.
Continuous time models include the Weibull and the Cox proportional hazard model. Hazard rates
or hazard ratios can be predicted from these regressions and then used in regression (29). We focus
on discrete-time duration analysis, but provide results from a continuous time analysis as a
robustness check.
with a country pair, while our data is a panel with country and time dimensions. Furthermore, most of the explanatory variables considered by Baier and Bergstrand are either geographical, which do not change over time, or “structural,” in the sense of changing little over time (e.g. factor endowments). Since we work with a panel, our fixed effects capture all of those fixed/almost fixed factors.
20 Simply substituting the binary variable enddemo as Prob(enddemo) in equation (29) and running logit for equation (28) would cause logical inconsistency. As summarized in Maddala (1983, p. 118), for logical consistency
either α1 or β1 in equations (28) and (29) must equal zero, which would make our study irrelevant.
![Page 24: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/24.jpg)
24
In the Weibull model, the hazard function is 1−ϕβ′ϕ= tXth t )exp()( , where φ is the shape
parameter to be estimated and t is the duration time. The Weibull model is suitable for modeling
data with monotone hazard rates that either increase (φ >1) or decrease (φ <1) exponentially with
time (if φ=1, the Weibull distribution reduces to the exponential distribution, which is associated
with a constant hazard over time.) In the Cox model, the hazard is assumed to be
)exp()0()( tXhth β′= , where h(0) is the baseline hazard. The coefficients are assumed to be the same
regardless of group (country*spell), but the baseline hazard is allowed to be group-specific.
For the structural FTA regression, instead of using country-year panel data, we can
alternatively employ a bilateral FTA panel dataset and also apply a discrete-time duration analysis.
Each observation in the bilateral data corresponds to two countries. The dependent variable is a
dummy indicating FTA relationship between two countries in a given year. We can include in the
data the average predicted hazard rates of the two countries in the pair. We would expect to see a
positive impact of the average hazard on bilateral FTA formation.
Researchers usually resort to discrete choice regressions (e.g. probit or logit) for binary FTA
data analysis. The ordinary binary choice analysis is acceptable in cross section analysis, as in Baier
and Bergstrand (2004), if we assume most of the variations are time-invariant. A panel data analysis
is usually better as it can provide richer information over time and is more capable to handle the
problem of unobserved heterogeneity. The ordinary binary choice analysis is, however,
inappropriate for panel data analysis because it assumes that the dependent variable (FTA dummy)
is conditionally independent over time.21 Following Liu (2008, 2010), we address this problem by
applying a discrete time duration analysis. For the discrete FTA variable, this method corresponds to
standard complementary log-log (cloglog) or logistic regression. All we need to do is drop all but the
first positive outcome of the dependent variable for each country pair over the sample period. Once
the repeated “1”s are dropped, the problem of conditional dependence in the standard logit analysis
disappears. Note that the event failure in this instance is two countries agreeing to a trade agreement
and a spell is defined as the length of time until two countries form an agreement.
It is easy to show that, when the probability of positive outcomes is small as in the case of
FTAs, a cloglog link function is very close to a logistic link function. Because logit is more commonly
used than cloglog, we use logit in this paper. We need to take into account the duration dependence,
i.e. the extent to which the conditional hazard of an FTA is rising or falling over time. If year
dummies are used to account for duration dependence, all the years without any new FTA would be
21 For example, Mexico signed NAFTA with the U.S. and Canada in 1994, and NAFTA remains in place for
all the following years. So the independence assumption is obviously violated.
![Page 25: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/25.jpg)
25
dropped because the year dummies could perfectly predict these zero outcomes. To avoid this
problem, we create a time counter to count the number of years already passed since the beginning
of our sample, as well as its square, cubic terms and so on. Then this polynomial is used to account
for the time dependence. The order of the polynomial is determined by the best fit of regressions.
We will also consider the issue of unobserved heterogeneity in the duration analysis. In the duration
analysis literature, the unobserved heterogeneity is called “frailty”, analogous to the fixed effects or
random effects in panel data. If we assume a normal distribution for the unobserved heterogeneity,
we can use random effects cloglog or random effects logit.22
4.B. Endogeneity
An important issue in our analysis is endogeneity, or reversed causality between FTA and
Prob(enddemo). Since we do not estimate the two equations jointly, we have to address the
endogeneity problem in each equation. Fortunately, this problem is avoided in both equations due
to the design of our regressions.
In our structural estimation (29), the endogeneity of Prob(enddemo) is not a problem
because we use the predicted Prob(enddemo), which is a function of exogenous variables, not
including the FTA variable. In other words, the predicted hazard in the ∆FTA equation is the
exogenous component of Prob(enddemo). In the bilateral structure regressions, the endogeneity
problem is further reduced due to the fact that we drop the repeated “1”s of the FTA dummy.
Keeping only the first positive outcome, we can hardly think of any feedback of FTAs on the
predicted hazard of enddemo. This is an additional benefit of duration analysis compared to regular
logit or probit analysis.
Regarding the endogeneity of the FTA variable in the enddemo regressions, it may not be a
problem if Prob(enddemo) only affects the changes in FTAs, not its levels. Basically, a country could
be already engaged in a couple of agreements but, for other reasons, face a high probability of
democratic failure; forming a new FTA would be a way to lower that probability. Similarly, a
country that plans to sign more FTAs (partially for the sake of rent destruction) may not necessarily
have a lot of existing FTAs. More importantly, if the risk of enddemo indeed affects FTA (positive
impact as in our structural regression), this reverse causation should most likely lead to an over-
estimation of our coefficient of the lagged FTA in the enddemo regression. Without addressing the
endogeneity issues, we find a negative effect of FTA on enddemo. Had we solved the endogeneity
22 No consistent fixed effect cloglog procedure is available. The fixed effect logit procedure (i.e. conditional
logit) is available but inappropriate due to information loss. Because most of the country pairs have never signed any FTAs, they would be dropped in fixed effect logit regressions.
![Page 26: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/26.jpg)
26
problem, the true estimate should then be even more negative. In other words, the reverse causality
problem biases against the hypothesis that FTA reduces the risk of enddemo.
But we also provide econometric evidence that no endogeneity problem exists in our
enddemo duration regressions. To address the endogeneity problem of FTAs, we cannot use 2SLS
because our logit regression is nonlinear. We cannot use the predicted FTA from a first step
regression in the second step enddemo regression either. There is no well defined bivariate
distribution in this approach because the two steps follow normal and extreme value distributions,
respectively.
Thus, we use the two-step procedure defined as the “control function approach” developed
by Petrin and Train (2010). This procedure works as follows. In the first stage, we estimate FTA with
instrumental variables and predict the residual. In the second stage, we add to the enddemo
regression the predicted residual and possibly its higher order terms as the "control function" to
solve the endogeneity problem. The correct standard errors can be obtained by bootstrapping
methods.
For the first stage IV estimation, we use “remoteness” as our instrument. Remoteness is
defined as the distance of a country to the rest of the world weighted by all other countries’ GDP in a
given year:
(31) ∑∑≠≠
=im
mtim
mtmiit GDPGDPceDismoteness /)tan(Re .
Gravity model theories predict that remoteness, as an index of “multilateral resistance” (Anderson
and Wincoop 2003), increases bilateral trade. By similar logic, remote countries may tend to seek
FTAs to compensate for their natural economic isolation from the rest of the world. By contrast,
there is no clear theoretical reason for why remoteness could have an independent effect on the
likelihood of democratic survival (especially after controlling for FOR). Thus, we assume that
remoteness is uncorrelated with the error term in the enddemo regression. Since our remoteness
variable is time varying due to the GDP weight, it can be used as instrument in our FTA regressions
with country fixed effects. As we will see, the remoteness variable is highly significant, hence a
strong instrument for FTAs.
The control function approach treats the endogeneity as an omitted variable problem. The
predicted residual can be considered a proxy of the omitted variable. If the predicted residual as
well as its higher order terms (i.e. the control function) are jointly significant in the enddemo
![Page 27: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/27.jpg)
27
regression, it implies that there is indeed an endogeneity problem with the variable FTA. The control
function approach can also be used to control for the omitted variables. As we will see, the control
function is highly insignificant in our estimations, implying that endogeneity is not an issue in our
enddemo regressions.
5. DATA
We have a panel with 133 countries over 1948-2007. Countries that have never experienced
democracy are dropped because we only look at democratic spells. Appendix 1 lists the countries
covered in our enddemo duration analysis. More than 200 countries are covered to constructing our
FTA measures, as explained below.
In our empirical analysis, free trade agreements cover both free trade areas and customs
unions (FTA/CU), which we call full-fledged regional trade agreements (RTAs). However, we will
check the robustness of our results by including the partial-scope RTAs as well (PTAs). Our
preferred measure of RTAs is a country’s imports with RTA partners as a share of its total imports in
a given year:
� FTA_impsh: a country’s imports from FTA/CU partners as a share of its total imports;
� RTA_impsh: a country’s imports from all RTA partners as a share of its total imports.
The import data are from the IMF Direction of Trade Statistics. We also construct some alternative
measures which will be discussed in the results section. To construct these measures, we carefully
consider the dates of the formation of new blocs, of the accession of new members, and of the de-
activation of existing blocs. Appendix 2 lists the RTAs in our dataset with their types (FTA, CU or
PTA), as well as the data sources (see footnotes).
The enddemo variable is created from Polity scores, which vary from -10 to 10, with higher
values representing more democratic regimes. We define a regime as “democratic” if its polity score
is strictly positive. For a democratic spell, enddemo is zero as long as a democracy remains
uninterrupted and becomes unity when it ends. If a democracy does not end during our sample,
enddemo only takes zeros (right-censored). These countries simply contribute a string of zeros, with
no final one, to the likelihood. There are 91 episodes of enddemo in our sample; Appendix 3 lists
them.
Notice that some countries have multiple democratic spells. In the duration analysis, we
treat those spells as if they belonged to different countries. That is, our unit observation is a
country’s democratic spell. In our duration analysis, we cluster standard errors by country*spell and
![Page 28: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/28.jpg)
28
use country*spell random effects when considering unobserved heterogeneity across countries. The
results are similar regardless of how we deal with the issue of multiple spells. In the ∆FTA
regressions, we use country fixed effects rather than country*spell fixed effects.
The DOM and FOR variables are also created based on polity scores. DOM is defined as
∑−=
=−−=
0
0,)1(
tt
tiit dDOMτ
τ
ττδδ ,
where δ is a discount factor and di,t-τ is a dummy for a strictly positive Polity score. As Persson and
Tabellini (2009), we find that what really matters for democratic stability in DOM is current DOM
(i.e. the current democratic spell), while past DOM is usually insignificant in the regressions.
Therefore, we use current DOM (dc95_pt_cur) in all of our regressions, meaning that t0 corresponds
to the first year in which dit = 1 in the current democratic spell. For the discount factor, we adopt δ =
.95; results change little for δ ∈ [.94, .99], the range considered by Person and Tabellini.
In turn, FOR is defined as
∑≠
−=
ijt
ijjtit N
DEq
DistPolityFOR /1 ,
where Polityjt is country j’s Polity score at t (rescaled to the [0,1] interval), Distij is the distance
between the capitals of countries i and j, DEq is half the length of the equator, and Nt is the number
of independent countries in the world at t.
GDP per capita data are from the World Development Indicators (WDI) database. Data on
wars are from the Correlates of War (COW) dataset, including any extra, inter and intra wars a
country was involved. Legal origin data are from La Porta (1999). Colony history variables are from
CIA’s World Fact Book (2004). The WTO membership data are from the WTO website. Trade
openness measures are obtained the Penn World Table 6.3. Please refer to Table 1 for the definitions
of all the variables used in the regressions, as well as for some descriptive statistics. The data used
for the bilateral analysis are based on Liu (2010).
6. EMPIRICAL RESULTS
6.A. Does participation in FTAs affect democracy survival?
We study first the impact of lagged FTA participation on the duration of democracy. We
start by comparing the Kaplan-Meier nonparametric survival curves for countries with and without
FTAs. As Figure 2 shows, democracies without FTA/CU (bottom curve) fail more quickly than those
![Page 29: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/29.jpg)
29
with FTA/CU (top curve). A logrank test also rejects the null hypothesis that both groups face the
same hazard of failure, with a p-value of 0.0014. This, however, is unconditional evidence without
control variables. In our regression analysis, we use various types of discrete-time and continuous-
time duration models.
Tables 2A and 2B show the results from duration analysis for full-fledged RTAs (FTA/CU)
and all types of RTAs, respectively. Most of the time-varying covariates are lagged by one year to
alleviate potential endogeneity problems. The coefficient of RTA import share is always negative
and significant, at least at the 10% level. This result supports our first hypothesis that FTAs can
reduce the probability of democracy failure. Regression (1) of Table 2A uses only the FTA/CU
import share variable and it is highly significant. This variable alone explains more than 5% of the
variations in enddemo as shown by the Pseudo R2. In regression (2) we add other explanatory
variables and the duration dependence terms. It turns out that a second order polynomial of the
time counter produces the best fit of the model. As expected, the duration dependence terms are
highly significant. The coefficient of duration and duration^2 are positive and negative, respectively.
This implies an inverted-U shape of the impact of duration on hazard rate with a cutoff duration of
about 23 years. In other words, when a democracy is younger than 23 years, the hazard of
democratic breakdown increases with the the age of democracy; after 23 years, the hazard starts to
decrease with the age. FTA/CU import share remains significant at the 10% level.
Due to possible unobserved heterogeneity, in regression (3) we use country*demo spell
random effects (or “frailty”). The FTA/CU import share variable again displays a negative sign, and
becomes even more significant statistically. The LR test of the random effects, however, is only
marginally significant at 10% level. Moreover, the changes in the estimated coefficients are overall
very small. This suggests that unobserved heterogeneity is relatively unimportant to explain the
breakdown of democracy.
Columns (4) and (5) of Table 2A show results for the continuous duration models, the
Weibull and the PH Cox proportional hazard models, respectively. In those models, the dependent
variable measures the age of a democracy (or the number of years passed since the onset of a
democratic regime until it was interrupted or (right-) censored).23 This variable is the same as the
time counter we use for the duration dependence in columns (2) and (3). All other covariates are the
same as those in the discrete duration analysis. The duration dependence is specified parametrically
(Weibull model) or non-parametrically (PH Cox model). The dataset is a multiple-record survival
23 If a country started with a democratic regime at the beginning of our sample (year 1948), 1948 is assumed
as the onset of the democratic spell (“left-censoring”).
![Page 30: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/30.jpg)
30
dataset because a country may have multiple observations that are either failures or right-censored.
An ID or group variable (country*demo spell) is specified to make sure that the multiple records for
each country*demo spell are not taken as separate records for different countries. Our first
hypothesis is strongly supported by the results from the Weibull regression. The estimated shape
parameter φ is significantly larger than 1, which implies that the hazard increases with the age of
democracies. For example, this estimate implies that, after 20 years, a democracy are 24 times more
likely to fail than after 10 years, ceteris paribus (i.e., (20/10)5.6-1=24). In the PH Cox regression, the
results again support our hypothesis that more intense participation in FTAs helps to consolidate
democracies.24
In the last column of Table 2A, we rerun the enddemo regression in a linear probability
model (LPM). Despite some well-known drawbacks, LPM is simple and easy to interpret and
therefore is often used in applied work. Because LPM is inherently heterosckadastic, we include
country*demo spell fixed effects and report robust standard errors. The RTA import share variable
remains statistically significant at 5% level.
Are these estimates economically significant? The results from different models should be
interpreted differently. In the LPM, the coefficient measures the impact of the covariates on P which
denotes Prob(enddemo). In the logit model, an exponentiated coefficient provides an estimate for
the impact of a one unit change in a covariate on the odds ratio of enddemo (i.e., exp(β) = [P1/(1-
P1)]/[P0/(1-P0)], where P1 = Prob(enddemo|X1); P0 = Prob(enddemo|X0), and X0 and X1 represent the
different values of X). In the Weibull and PH Cox models, an exponentiated coefficient provides an
estimate for the impact of a one unit change in a covariate on the hazard ratio of enddemo (i.e.,
P1/P0). If the risk of democracy failure is very small, the odds P/(1-P) and hazard rate P are
approximately similar. Therefore the coefficients under logit, Weibull, and HP Cox model are more
directly comparable than those under the LPM. After some simple transformations, however, we can
approximately interpret the coefficients from any of these models in terms of changes in hazard rate
(P). The random effect logit regression result in column (3) of Table 2A implies that one percentage
point increase in FTA/CU import share will decrease the odds of enddemo (P/(1-P), similar to
hazard rate, P, when P is very small) by about 2.66% (i.e., exp(-2.697/100)-1=-2.66%). The
24 Proportional hazard (PH) refers to the effect of any covariate having a proportional and constant effect
that is invariant to when in the process the values of the covariate changes. We test the PH assumption and find no evidence that the model we specified violates the PH assumption either globally or with respect to each covariate.
![Page 31: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/31.jpg)
31
corresponding estimates from the Weibull, PH Cox and LPM regressions are 2.35%, 2.13%, and 1.7%
decreases in the hazard.25
Other covariates usually have the expected signs. GDP/capita, current domestic capital,26
foreign capital and UK colony dummy have negative and statistically significant impacts on
enddemo, while the estimated coefficients of most other variables are insignificant in the
regressions.
Table 2B reports the enddemo results for all types of RTAs, including both the full-fledged
FTA/CU and the partial-scope PTAs. The results are similar to those in Table 2A. The coefficients of
the FTA/CU and All-RTA import share variables remain significant, except for the LPM regression.
The magnitude of the coefficients for the import share variables is however smaller than in Table 2A.
This is expected because the partial-scope RTAs are incomplete processes of preferential trade
liberalization, with many exceptions and special treatments.
6.B. Are unstable democracies more likely to seek participation in FTAs?
We now turn to our second hypothesis. We rely on a structural estimation by predicting the
hazard rate from the duration analysis and then estimating how the predicted hazard rate affects
FTA formation.
The results from our main specification are reported in the first three columns of Table 3A.
The first column shows the enddemo duration regression and the next two columns display the
∆RTA regressions with the predicted hazard for FTA/CU and All-RTA respectively. As discussed in
Section 4, we do not include the RTA variable in this first stage to avoid an endogeneity problem in
the second stage. We include a second order polynomial of the predicted hazard rate to the second
stage ∆RTA regression to check for possible nonlinear effects. In columns (2) and (3), the dependent
variable is the change in the RTA import share from the previous year. Year dummies are included
to capture the recent increasing trend in RTA growth. To control for unobserved heterogeneity
across countries, country fixed effects are also included in the regression. Finally, we exclude DOM
and FOR as well the duration dependence terms from that regression as the exclusion restriction.
Because hazard is predicted from the first stage with sampling errors, we use bootstrapping (100
replications) to adjust the standard errors in the ∆RTA regressions.
25 These estimates are in percent, not percentage. Based on the average predicted hazard of 0.023 as shown
in Table 1, these estimates amount to about 0.0006, 0.0054, 0.0005 and 0.0004 percentage point decreases on average in the hazard for xtlogit, Weibull, PH Cox and LPM respectively.
26 DOM actually bears an unexpected positive sign in the LPM, different from all the other regressions. This may indicate some potential problems with the LPM specification.
![Page 32: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/32.jpg)
32
In column (2) FTA/CU regressions, the coefficients of the first order predicted hazard rate
and its quadratic term are both significant at 10%, positive and negative respectively. This implies an
inverted-U relationship between hazard rate and FTA formation with an estimated cutoff value of
0.225. When hazard<0.225, FTA/CU formation increases with the hazard; when hazard>0.225,
FTA/CU formation decreases with the hazard. As shown in Table 1 and Figure 3, the estimated
hazard rate ranges from 7.81E-8 to 0.379, with a mean 0.023. Only 6 of the predicted hazard rates
(among a total of 2603) are larger than the cutoff value.27 Thus, unless the risk of democratic failure
is exceedingly high, unstable democracies tend to form more FTAs than stable democracies do.
We can also quantify the magnitude of the effect of the predicted hazard on the changes in
∆FTA. With the quadratic term of the hazard, this effect is nonlinear. At the mean value of the
hazard (0.023 as shown in Table 1), doubling the hazard from 0.023 to 0.046 will lead to about one
percentage point increase in the FTA import share [i.e., (0.474-2*1.051*0.023)*0.023=0.01].
Column (3) of Table 3 reports the results from the analogous exercise for All-RTAs. Results
are largely unchanged, except that the second order hazard turns insignificant and the cutoff hazard
rate is lower (but still higher than more than 99% of the predicted hazards).
In the last two columns of Table 3A, we repeat the analysis in the previous two columns but
including DOM, FOR as well as duration dependence terms in the second stage RTA regressions.
The purpose of doing this is to check if our results are sensitive to the exclusion variables we used.
There we rely solely on the functional form (i.e. the nonlinearity of the first stage logit regression) to
identify the coefficients of the predicted hazard in the second stage. The results prove to be largely
insensitive to those changes. The excluded variables are highly insignificant except FOR.28
6.C. A bilateral analysis of the structural regression
We also run bilateral structural regressions. For this we use a large bilateral panel dataset
from Liu (2010), covering years 1960-2000. Each observation is associated with two countries as a
pair. A country pair appears only once in the data as single-dyad (either ij or ji). The dependent
variable is a dummy variable, which is equal to one if two countries had an RTA in a year and zero
otherwise. The RTA data are from the WTO’s RTA website and other sources (see footnotes in
Appendix 2). Our key explanatory variable is Hazard_avg, which is the average predicted hazard
27 These six extreme hazard rates are for Bangladesh and Burkina Faso. 28 We also tried excluding DOM and the duration dependence terms while including FOR in the second
stage; the results again hold well.

based on the enddemo logit regression in the first column of Table 3A.29 Other covariates include the
sum and the absolute difference of two countries’ GDP in a pair, the absolute difference in
GDP/capita, the great circle distance, land contingency or border dummy, the differences in labor
and environment standards (proxied by the absolute differences in their child labor ratios and
Carbon Dioxide/capita), common colony dummy, military conflict, political alliance, and the
product of the two countries’ remoteness as defined in equation (31).
The results from the bilateral analysis are reported in Table 3B. The first two columns are for
FTA/CU and All-RTA, respectively, using pooled data without country pair random effects; the last
two columns consider the unobserved heterogeneity by including country pair random effects. In all
the regressions, the average predicted hazard has a positive and significant impact on RTA
formation. Most of the other variables have the expected signs as well.30
6.D. Endogeneity
To address the endogeneity problem of FTA in the enddemo regressions, we adopt the two-
step control-function approach, as suggested by Petrin and Train (2010). The results are reported in
Table 4. Column (1) reports the first stage RTA import share regression. The explanatory variables
include all the covariates in the enddemo regression plus an instrument—remoteness, as defined in
equation (31). The remoteness variable is highly significant in the regression, suggesting that it is a
strong instrument.
In the second stage enddemo regression (the second column of Table 4), we include as an
additional variable the predicted residual from the first stage FTA regression. The predicted residual
(i.e., the control function) turns out to be highly insignificant in the enddemo regression, which
implies that endogeneity is not a problem. Higher order terms of the residual, if included, are also
insignificant. Adding this control function has little impact on our estimates. The results with the
control function in column (2) of Table 4 are very similar to those without control function in column
(3) of Table 2A.
Strictly speaking, the standard errors of the control function reported in the second column
of Table 4 are under-estimated because the control function is estimated. The correct standard errors
could be obtained by bootstrapping and would be larger than those reported in Table 4. But it is not
29 When one of the countries in a pair has missing hazard data, the non-missing hazard of the other country
is taken as Hazard_avg. 30 We did not include the quadratic term of the average hazard because it is always highly insignificant.
![Page 34: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/34.jpg)
34
necessary to calculate the bootstrapped standard errors, since the control function is already highly
insignificant even with the downward biased standard errors.31
6.E. Robustness
We discuss in this section the robustness of our results in several ways. First, some studies
show that openness affects democracy (e.g., Mansfield, Milner, and Rosendorff, 2003; Mansfield,
Milner, and Pevehouse, 2008). To make sure that our FTA measure is not capturing just that, we
include an openness variable (defined as (imports+exports)/GDP) from the Penn World Table 6.3
and a WTO membership variable as additional regressors to our existing enddemo regressions. The
results are reported in Table 5. Results are similar to those from Table 2A, and the two newly added
variables are always highly insignificant.
Another issue is whether it is really the expectation of regime change (proxied by the
predicted hazard) that induces more FTAs. One alternative is that the change in regime itself causes
more FTAs. Another is that the regime itself has an effect (i.e. being democratic induces more FTAs).
Our estimated hazard, recent changes in political regime and current democracy status ought to be
correlated. To test whether it is indeed the expectation of regime change that matters, we include in
the ∆FTA regression both the predicted hazard and one of the following variables: (1) demp_pt, a
dummy indicating the current democracy status (i.e., whether polity>0); (2) reg_change, a dummy
indicating if a country’s polity scores changes signs (from strictly positive to non-positive or vice
versa); and (3) var(Polity)_10yr, the variance of polity scores during the last 10 years, which is used to
capture the regime stability in the previous 10 years. The results are reported in Table 6. In all the
three cases, the newly added variable is always highly insignificant, while the predicted hazard and
its quadratic term remain statistically significant. These results suggest that what really matters for
RTA formation is indeed the expectation of a regime change.
It is also possible that the empirical results may be actually identifying a more general
phenomenon than the model suggests. For example, it is possible that governments may form more
FTAs as a consequence of general political competition within an electoral system, and not
specifically because of the threat from autocrats. If the risk of democratic collapse is positively
associated with more political competition within a democracy, our finding that the threat of the
democratic system induces FTA formation may be driven by regular political competition within a
democracy. To test for that, we include a measure of political competition in the ∆FTA regression.
31 Under the null hypothesis that the control function is insignificant in the second stage, the t and F
statistics in the second stage remain valid.
![Page 35: FREE TRADE AGREEMENTS AND THE CONSOLIDATION OF …tbesedes3/liu.pdf · implies that governments in fledgling, unsecure democracies will have an extra motive to engage the country](https://reader035.vdocuments.us/reader035/viewer/2022070804/5f0372cc7e708231d4093c9c/html5/thumbnails/35.jpg)
35
We use the variable POLCOMP from Polity IV, which codes the degree of political competition in
the country.32 The results are reported in the last column of Table 6. Again, the newly added variable
is highly insignificant, while the predicted hazard and its quadratic term remain statistically
significant. This suggests that regular political competition in a country is not an important driver of
FTA formation, unlike the expectation of a regime change.
To further reinforce our confidence in the political economy explanations of our results, as a
falsification exercise, we run some regressions also for endauto (i.e. the end of autocracy spells)
instead of enddemo. The results are shown in Table 7. FTA variables are always highly insignificant.
As discussed above, given the tremendous heterogeneity in countries and FTAs, we believe
the FTA import share variable measures more precisely the importance of the FTAs than other
measures. It is nevertheless useful to check if our results still hold when alternative measures of
FTAs are used.33 We experiment first with a measure that counts the number of FTAs a country is
involved in a given year. Our findings hold very well. We also try a measure that counts the number
of FTA partners a country has in a given year, and a measure of the total economy size of all FTA
partners relative to the country’s own economy size. These last two measures do not yield as
consistent estimates as the other measures when the whole sample is used (estimates are often less
significant, although the signs of the coefficients are still expected in most cases), but do when the
poorest countries are excluded from our sample.34
Put together, these robustness checks boost confidence that we are capturing our intended
mechanism, rather than the workings of some omitted variable that affects both FTA formation and
political regimes in general.
7. CONCLUSIONS
[To be added]
32 This variable measures both the regulation of participation and the competitiveness in the political
process. According to the Polity IV Dataset User’s Manual, POLCOMP reaches its maximum score when “relatively stable and enduring political groups regularly compete for political influence and positions with little use of coercion; ruling groups and coalitions regularly, voluntarily transfer central power to competing groups; and no significant groups, issues, or types of conventional political action are regularly excluded from the political process.”
33 We do not report the results here to save space, but they are available from the authors. 34 Here the poorest countries are those with an average GDP/capita (in 2000 constant price) over 1960-2007
less than one dollar a day (similar to the poverty line defined by the World Bank).
