According to the enforcement school, a key problem in international cooperation is that states have incentives to violate international agreements (Keohane, Reference Keohane1984; Downs et al., Reference Downs, Rocke and Barsoon1996; Downs, Reference Downs1997, Reference Downs2000; Gilligan, Reference Gilligan2004; Carrubba, Reference Carrubba2005). Mutually profitable international cooperation requires the defectors and free riders be punished through sanctions or suspension of cooperation. But not all international cooperation theorists find enforcement so important. For managerialists, the complexity and ambiguity of international cooperation problems dominate enforcement concerns (Mitchell, Reference Mitchell1994; Chayes and Chayes, Reference Chayes and Chayes1995; Young, Reference Young1999; Tallberg, Reference Tallberg2002). In addition to transparency and rule interpretation, they emphasize capacity building as the key to successful international cooperation.
This study examines the relationship between enforcement and capacity building in international cooperation. In a game-theoretic model, a wealthy donor offers foreign aid to a poor recipient in exchange for policies that eradicate international externalities, such as environmental deterioration. I incorporate enforcement concerns by assuming that policy implementation is costly to recipient. Recipient has limited capacity to comply with international agreements, so compliance failure sometimes occurs despite genuine willingness to comply. A key problem is, therefore, that compliance failure could result either from inadequate capacity or willful disobedience, so the donor does not know if punishment is warranted. For example, Indonesia has consistently failed to reduce illegal logging despite promises made to donors of foreign aid, but it is unclear whether this failure should be mostly attributed to lacking political will or a genuine failure to address the rampant corruption that undermines environmental policies in the country.Footnote 1 This problem is so serious that deforestation makes Indonesia the third largest net emitter of greenhouse gas emissions, right after the United States and China.Footnote 2
I compare two canonical enforcement mechanisms. Under reversion, mutual suspension of international cooperation follows perceived compliance failure (Axelrod, Reference Axelrod1984; Axelrod and Keohane, Reference Axelrod and Keohane1985; Keohane, Reference Keohane1986; Conybeare, Reference Conybeare1987; Downs and Rocke, Reference Downs and Rocke1995; McGillivray and Smith, Reference McGillivray and Smith2000; Langlois and Langlois, Reference Langlois and Langlois2001). If the recipient appears to defect, both sides lose mutually profitable international cooperation for a period of time. Under compensation, a defector must compensate the other state to restart international cooperation (Barrett, Reference Barrett1999; Rosendorff and Milner, Reference Rosendorff and Milner2001; Carrubba, Reference Carrubba2005; Rosendorff, Reference Rosendorff2005; Svolik, Reference Svolik2006). If the recipient appears to defect, it must continue to cooperate whereas foreign aid is temporarily frozen. I focus on these stylized enforcement mechanisms because they capture an important feature of any international enforcement mechanism: does the enforcer prefer to implement the punishment or not? They are also variants of reciprocity, which according to Keohane (Reference Keohane1984: 214) ‘seems to be the most effective strategy for maintaining cooperation among egoists’.
The central theoretical result is that the choice of enforcement mechanism shapes donor incentives to fund capacity building. Under reversion, mutually profitable international cooperation is suspended every time the recipient appears not to comply. Thus, the donor has an incentive to build capacity so as to reduce the rate of spurious compliance failure. Under compensation, foreign aid is frozen if the recipient appears not to comply. Now the donor has an incentive not to build capacity because it can thus hold the recipient accountable for perceived compliance failure more frequently. Reversion unambiguously aligns preferences for capacity building, while compensation reduces the donor incentive to fund capacity building unless international cooperation is otherwise impossible. Strikingly, this result holds even if capacity building is costless.
The result is important for several reasons. Firstly, it contributes to the research program on international compliance (Chayes and Chayes, Reference Chayes and Chayes1995; Downs et al., Reference Downs, Rocke and Barsoon1996; Tallberg, Reference Tallberg2002). Although previous scholarship has posited enforcement and capacity building as competing accounts of compliance, this result shows that they interact in complex ways. Indeed, the result could explain why powerful states accept reversionary enforcement mechanisms despite potentially costly consequences. These mechanisms allow a credible commitment to capacity building, so the value of international cooperation to weak states increases, so that powerful states can build a legitimate and mutually profitable international order and avoid the high cost of coercion (Ikenberry, Reference Ikenberry2000; Stone, Reference Stone2008). Secondly, it improves our understanding of international institutional design, especially as it depends on the relationship between distributional conflict and enforcement concerns (Abbott and Snidal, Reference Abbott and Snidal1998; Fearon, Reference Fearon1998; Koremenos et al., Reference Koremenos, Lipson and Snidal2001). If the choice of an enforcement mechanism influences willingness to build capacity, then these decisions are interdependent.
Thirdly, it can help us to understand the politics of legitimacy in international relations (Hurd, Reference Hurd1999; Clark, Reference Clark2003; Reus-Smit, Reference Reus-Smit2003). At first sight, reversionary enforcement appears normatively troubling because it hurts the innocent victims of perceived wrongdoings. However, it could ultimately align state preferences over capacity building and thus contribute to deeper cooperation in the long run. Finally, the result has notable implications for the study of foreign aid (Alesina and Dollar, Reference Alesina and Dollar2000; Burnside and Dollar, Reference Burnside and Dollar2000; Easterly, Reference Easterly2002; Bueno de Mesquita and Smith, Reference Bueno de Mesquita and Smith2009). Many scholars have emphasized that giving fungible resources to a government invites corruption and rent seeking. By contrast, capacity building could be particularly conducive to long term development. Thus, reversionary enforcement could reduce the benefits of giving foreign aid by shifting the focus from capacity building to cash transfers.
I first discuss the relationship between enforcement and capacity building in light of the extant literature. I then introduce the model and conduct the analysis. In the concluding section, I discuss the central theoretical and empirical implications of the results.
Enforcement and capacity building
An important debate in international cooperation theory is that between the enforcement and managerial schools of compliance.Footnote 3 The enforcement school builds on ideas articulated by Downs et al. (Reference Downs, Rocke and Barsoon1996) who argue that states have incentives to violate international agreements even if they have previously ratified them. In the absence of a centralized enforcement mechanism, such as an omnipotent and benevolent world government, states monitor and sanction behavior by threatening defectors and free riders with punishment (Keohane, Reference Keohane1984; Axelrod and Keohane, Reference Axelrod and Keohane1985; Downs and Rocke, Reference Downs and Rocke1995; Carrubba, Reference Carrubba2005). To facilitate these tasks, states design international institutions accordingly by establishing dispute resolution mechanisms, monitoring bodies, creating collective enforcement power through issue linkage, and so on (Snidal, Reference Snidal1996; Koremenos et al., Reference Koremenos, Lipson and Snidal2001).
For managerialists, enforcement is a secondary problem in international cooperation. International cooperation problems are complex and ambiguous, but states usually sign and ratify international agreements under a genuine intention to comply with them. Thus, Chayes and Chayes (Reference Chayes and Chayes1995: 22) write, ‘[i]f we are correct that the principal source of noncompliance is not willful disobedience but the lack of capability or clarity or priority, then coercive enforcement is as misguided as it is costly’. In addition to rule interpretation and transparency, Chayes and Chayes (Reference Chayes and Chayes1995) emphasize the importance of adequate capacity to implement policies. Tallberg (Reference Tallberg2002: 614) summarizes this concern as follows:
Whereas some political and economic capacity problems are beyond the reach of international efforts, deficits in technical knowledge, bureaucratic capability, and financial resources maybe partially or entirely offset through capacity building. Often, capacity building is one of the main programmatic activities of international regimes; in other cases, technical and financial assistance is a targeted measure to alleviate a particular problem.
Capacity building is particularly important in the context of North-South international cooperation. Developing countries have limited capacity to implement complex policies necessary to improve trade policy, prevent environmental deterioration, eradicate or contain contagious diseases, reduce corruption, and so on (Barrett, Reference Barrett1994a, Reference Barrett2007; Keohane and Levy, Reference Keohane and Levy1996; Michalopoulos, Reference Michalopoulos1999; Finger and Schuler, Reference Finger and Schuler2000; VanDeveer and Dabelko, Reference VanDeveer and Dabelko2001; Guzman and Simmons, Reference Guzman and Simmons2005; Shaffer, Reference Shaffer2005; Suwa-Eisenmann and Verdier, Reference Suwa-Eisenmann and Verdier2007). And they do not have the financial and organization resources to increase that capacity. Thus, capacity building funded by wealthy donors appears central to successful and mutually profitable international cooperation.
Although, the enforcement and managerialist schools are often seen as competing accounts, it is interesting to note that enforcement concerns and lack of capacity could be mutually complementary.Footnote 4 Downs (Reference Downs1997: 330) recognizes this arguing that ‘[t]he claim that the political economy model is suspect because most treaty violations are caused by factors such as the ambiguity of treaties and capacity limitations rather than the product of premeditated exploitation is problematic because the former does not necessarily preclude the latter’. Indeed, enforcement can be complicated by lack of capacity. To see why, recall that if a state with limited capacity fails to comply, others do not know if the reason is an intended defection or an unintended managerial failure. Thus, inadequate capacity provides a smokescreen for opportunism. In the case of illegal logging in Indonesia that I have introduced, failure to prevent it could either stem from lack of political will or a genuine failure to improve the quality of environmental regulation because of bureaucratic ineffectiveness. Should the international community respond by reducing foreign aid as a punishment, or by increasing foreign aid for capacity building?
Although this dilemma is now in common knowledge among international cooperation theorists, the extant literature has little to say about the effect of alternative enforcement mechanisms on a wealthy donor’s incentives to contribute to capacity building. Intuitively, it seems plausible that the connection between enforcement and capacity building encourages donations because capacity building produces a double dividend. Not only does it solve managerial implementation problems, but it also improves the monitoring (Mitchell, Reference Mitchell1994). If the United States helps Ecuador develop implementation capabilities in rainforest conservation, Ecuador can improve forestry practices – and blaming inadequate capacity for implementation failure is simply not credible. Both effects seem desirable to a wealthy donor.
In the analysis, I compare two alternative enforcement mechanisms. Under reversion, future cooperation is contingent on past compliance with an international agreement but compensation for damage is not necessary (Axelrod, Reference Axelrod1984; Axelrod and Keohane, Reference Axelrod and Keohane1985; Keohane, Reference Keohane1986; Conybeare, Reference Conybeare1987; Downs and Rocke, Reference Downs and Rocke1995; McGillivray and Smith, Reference McGillivray and Smith2000; Langlois and Langlois, Reference Langlois and Langlois2001). For example, if the recipient defects, both foreign aid and policy implementation are temporarily suspended. Under compensation, a defector must compensate the other state (Barrett, Reference Barrett1999; Rosendorff and Milner, Reference Rosendorff and Milner2001; Carrubba, Reference Carrubba2005; Rosendorff, Reference Rosendorff2005; Svolik, Reference Svolik2006). This can be done so that the defector cooperates while the other state free rides for some time. For example, if the recipient defects, policy implementation continues for sometime while foreign aid is temporarily frozen.
Both enforcement mechanisms are based on the idea of reciprocity (Axelrod, Reference Axelrod1984). As Downs (Reference Downs2000: 323) writes, ‘[d]espite its name, the strategy of reciprocity is not designed to uphold some principle of equity-based justice’. Reversionary enforcement is based on reciprocity, but it does not allow compensation to the victims of non-compliance. In contrast, Keohane (Reference Keohane1986: 6) argues that reciprocity has a normative dimension because it is based on the principle of ‘mutual gain’. The compensation mechanism captures an important element of this normative dimension, because a victim of non-compliance will be compensated.
These enforcement mechanisms are highly stylized. In reality, states can choose from a broad inventory of enforcement mechanisms, ranging from simple reciprocity to issue linkage and institutionalized sanctioning mechanisms or binding dispute resolution (Keohane, Reference Keohane1986; Barrett, Reference Barrett1994b; Lohmann, Reference Lohmann1997; Koremenos, Reference Koremenos2007). The enforcement mechanisms that I study abstract away from the details and focus attention on the willingness of the enforcer to implement a punishment. Any enforcement mechanism that states could use also influences the payoff to the enforcer, so my main analytical results apply to a wide variety of possible enforcement mechanisms.
Intuitively, compensation seems superior for three reasons. Firstly, it does not inflict unnecessary damage on a victim of non-compliance (Chayes and Chayes, Reference Chayes and Chayes1995; Rosendorff, Reference Rosendorff2005). Secondly, compensation is not ‘renegotiable’ because a victim of non-compliance actually prefers compensation to business as usual (Farrell and Maskin, Reference Farrell and Maskin1989; Barrett, Reference Barrett1994b). In contrast, both states prefer not to implement the punishment under reversion. Finally, I show below that in an exchange relationship, compensation is easier to enforce than reversion. My key contribution is to show that states nevertheless often have good reasons to choose reversion over compensation, because the donor thus has stronger incentives to fund capacity building.
The Model
In the model, a wealthy donor and a poor recipient form an exchange relationship under which the donor funds policies that eradicate an international negative externality produced by the poor recipient. For example, the European Community and the United States have funded rainforest conservation in Brazil (Kolk, Reference Kolk1998). To improve the value of the exchange relationship, the donor can implement a capacity building program. For example, the United States could train Brazilian officials to enhance measures against illegal logging.
The exchange relationship is modeled as an infinitely repeated game with a common discount factor δ. At every time t∈{0,…,∞}, the donor chooses between contribution (c) and no contribution (d) and the recipient chooses between cooperation (C) and defection (D). The payoffs to the two states are given in Figure 1. The idea is that policy implementation is costly to the recipient, but this cost is lower than the benefit to the donor. Thus, policy implementation for foreign aid is mutually profitable.
To model the dilemma of enforcement under limited capacity, I use a technique called imperfect public monitoring (Mailath and Samuelson, Reference Mailath and Samuelson2006). After every period, both states know if the donor contributed or not.Footnote 5 But recipient behavior is imperfectly observable, so it could accidentally send a misleading ‘signal’:
(1) If the recipient cooperates, both states see a ‘defection’ signal with probability p and a ‘cooperation’ signal with probability 1−p.
(2) If the recipient defects, both states see a ‘defection’ signal with probability q and a ‘cooperation’ signal with probability 1−q.
To ensure that cooperation increases the probability of a favorable ‘cooperation’ signal, let p < q. Intuitively, these signals correspond to the impression that the donor gets about the recipient’s intentions. The ‘cooperation’ signal carries information that leads the donor to believe the recipient made a genuine effort whereas the ‘defection’ signal suggests otherwise. For example, the donor could consult local non-governmental organizations or audit implemented projects (Maxwell and Riddell, Reference Maxwell and Riddell1998; Dai, Reference Dai2002).
To keep the analysis simple, I consider a single capacity building project that the donor can implement before the repeated game at a small cost ε→0. This project improves the accuracy of monitoring, so that the donor learns how the recipient really behaved more often. Formally, probability p decreases while probability q increases with capacity building. The results hold even if capacity building reduces the cost of cooperation to the recipient, but I omit the unnecessary complication.
The purpose of an international agreement is to ensure that the donor contributes and the recipient cooperates. A simplifying assumption is that if the donor ever fails to comply with an international agreement, international cooperation is permanently suspended. Although unrealistic, this convenient assumption is innocuous because donor behavior is transparent. As long as the donor has incentives to comply, international cooperation never breaks down. I assume this condition holds because the discount factor δ is high enough so that there is a large ‘shadow of the future’ (Axelrod and Keohane, Reference Axelrod and Keohane1985). I can now simply ignore donor incentives and only focus on the difficulties with disciplining the recipient.
I consider two alternative international agreements. The only difference between them is the enforcement mechanism. First, reversion is based on the idea that if the recipient appears to defect, both foreign aid and cooperation are suspended for one period. Given that the donor has no incentive to deviate, the equilibrium strategies are as follows:
(1) During ‘compliance’, play (c, C). During ‘punishment’, play (d, D).
(2) Begin with ‘compliance’ at time zero. Play ‘punishment’ at time t + 1 if ‘compliance’ should have been played but the signal was ‘defection’ at time t. Play ‘compliance’ at time t + 1 otherwise.
Second, compensation is based on the idea that if the recipient appears to defect, it must compensate the donor by cooperating for one period while foreign aid is frozen. Given that the donor has no incentive to deviate, the equilibrium strategies are as follows:
(1) During ‘compliance’, play (c, C). During ‘punishment’, play (d, C).
(2) Begin with ‘compliance’ at time zero. Play ‘punishment’ at time t + 1 if the signal was ‘defection’ at time t.
Under reversion, ‘punishment’ play need not be enforced because the states are playing mutual best responses. Under compensation, ‘punishment’ play must be enforced because the recipient prefers not to cooperate so as to compensate the donor.
Analysis
In equilibrium, the recipient never defects on purpose, but ‘defection’ signals must nevertheless result in punishment because otherwise the recipient has no incentives to comply at all. Under reversion, it is clear that neither state ever deviates during ‘punishment’ because they are playing mutual best responses.
If the donor is supposed to contribute and the recipient is supposed to cooperate, the recipient has an incentive to comply if and only if
where V is the average payoff from the game to the recipient. The only effect of replacing a ‘cooperation’ signal with a ‘defection’ signal is one unavoidable period of reversion, as if mutually profitable cooperation was postponed by exactly one period. Under imperfect monitoring, we have 0 < V < x−1, so the cost of the punishment is less than the value of successful cooperation.
For ease of interpretation, this expression can also be written as
The left side is the immediate reward for avoiding the cost of cooperation. The right side is the expected cost of reversion in the following period. Note in particular that loss of cooperation is never certain for the recipient, so the loss is weighted by the increase in probability q−p < 1. The discount factor δ is present because punishment follows a period later.
Under compensation, the recipient must have an incentive to comply at any time, be it during ‘compliance’ or ‘punishment’. It is easy to verify that there is nevertheless only one constraint,
as the punishment consists of exactly one period of compensation. This expression can be written as
The left side is again the immediate reward for defection and the right side is the cost of possibly losing foreign aid. With x > x−1 > V, international cooperation is unambiguously easier to enforce under compensation than under reversion.
Is compliance possible? If the discount factor δ and the effect of defection on the probability of a ‘defection’ signal q−p are high enough, there exists a donation x such that international cooperation is mutually profitable and neither state has an incentive to defect on purpose. In this case, international cooperation is enforceable. Otherwise it is not enforceable. If international cooperation is enforceable, states play according to the international agreement. If international cooperation is not enforceable, the donor never donates and the recipient always defects.
Results
Capacity building increases the value of q and decreases the value of p. Under reversion, this also increases the average payoff to the recipient V, so capacity building unambiguously improves enforceability. I assume that international cooperation is enforceable with capacity building, and possibly but not necessarily without capacity building, as the analysis is trivial if international cooperation is not enforceable even upon capacity building. Capacity building is funded by the donor, so only donor incentives are to be considered.
Consider first reversion. Every period preceded by a ‘defection’ signal produces a zero payoff to the donor, while the payoff after a ‘cooperation’ signal is always 3−x > 0. Capacity building increases the probability 1−p of a ‘cooperation’ signal, so it is profitable to the donor:
Proposition 1 (preference alignment). Under reversion, the donor builds capacity.
As long as capacity building is not too costly, it is unambiguously profitable to the donor. The only effect of capacity building is to reduce the frequency of erroneous ‘defection’ signals that occur every now and then even though the recipient cooperates. Such ‘defection’ signals must trigger punishment that is unfortunately costly to both states under reciprocal enforcement. The silver lining for the recipient is that under reciprocal enforcement, the donor has strong incentives to build capacity.
This simple principle of preference alignment is very general for reversionary mechanisms. It does not depend on the assumption that capacity building increases the average payoff to the recipient, or the assumption that the length of the punishment period is one period. Under reciprocal enforcement, either both states or neither state profit, so the preference alignment is rather strong. Reversion implies that the donor suffers from the recipient’s inadequate capacity to implement cooperative policies, so capacity building is something that both sides prefer.
Consider now compensation. Every period preceded by a ‘defection’ signal produces a payoff 3 while every period preceded by a ‘cooperation’ signal produces a payoff 3−x. Clearly, 3 > 3−x. Capacity building increases the probability 1−p of a ‘cooperation’ signal, so the frequency of the higher payoff decreases. Thus, capacity building is not profitable if international cooperation is enforceable without it:
Proposition 2 (preference non-alignment). Under compensation, the donor builds capacity if and only if international cooperation is not enforceable otherwise.
If enforceability is guaranteed, donor–recipient preferences are diametrically opposed under compensation. Every time the recipient cooperates but the erroneous ‘defection’ signal results, the donor is given unwarranted compensation. As a result, the donor benefits from lack of capacity. But if international cooperation cannot be enforced without capacity building, the donor is willing to build capacity so as to achieve any international cooperation. Thus, the donor never really prefers to invest in capacity building, but it might have to do so for enforceability.
This result is almost diabolical because a seemingly benevolent enforcement mechanism removes the donor incentive to invest in capacity building even if this is costless. The two states have designed an international agreement that prescribes compensation, and the lure of this compensation prevents capacity building. It is essential to note that the result is qualified if capacity building increases the value of international cooperation to the donor (as opposed to the recipient). If this increase outweighs the reduced frequency of compensation, partial preference alignment is possible. But even here, full preference alignment is never possible because preferences over the quality of monitoring continue to be diametrically opposed.
The following example suggests that policymakers appreciate this logic. When the Global Environment Facility was first established in preparation for the 1992 Earth Summit, a largely unsuccessful pilot phase led donors and recipients to agree on rather egalitarian principles for the allocation of foreign aid for environmental protection (Streck, Reference Streck2001; Clémençon, Reference Clémençon2006). At the third replenishment of the institution in 2002, President Bush announced that the United States was no longer willing to give foreign aid to developing countries that do not meet stringent performance criteria related to good governance (Hicks et al., Reference Hicks, Parks, Roberts and Tierney2008: 54). This announcement provoked a furious response by the Group of 77 who argued that such conditionality would change the nature of the Global Environment Facility to the extent that it was completely unacceptable (al-Nasser, Reference al-Nasser2004). Although the United States ultimately prevailed, it is notable that other donor countries also resisted the idea (Hicks et al., Reference Hicks, Parks, Roberts and Tierney2008, 54).
The result on enforcement and capacity building can help us to understand these dynamics. It is not immediately clear why the developing countries should unanimously resist performance criteria, especially if the total amount of aid remains unchanged. It is equally surprising that other donor countries were unwilling to consider such performance criteria, given widespread public concerns regarding the efficacy of foreign aid. But if donors can legitimately reduce foreign aid upon perceived compliance failure, their incentives to support capacity building in the long term are diminished. Performance criteria force developing countries to correct implementation failures and implement reforms before additional foreign aid is available, so they strongly resemble the compensation mechanism that I have analyzed. The resulting negative effect on capacity building could explain why the other donors agreed with the developing countries that this was not a good idea, even if they were actually committed to global environmental protection.
Concluding Remarks
I have examined the relationship between enforcement and capacity building in international cooperation. The key result concerns the possibility of preference alignment for capacity building. If states cooperate in the shadow of an international agreement based on a reversionary enforcement mechanism, the donor has a strong incentive to build capacity for the recipient because it thus reduces the risk of cooperation failure. But if enforcement is based on compensation for perceived failure to cooperate, the donor could deliberately refuse to build capacity so as to obtain compensation more frequently. Although the game-theoretic model that I have analyzed is simple, this alignment theorem holds in a wide range of circumstances.
International cooperation theorists have not previously recognized this relationship. Other rationalist explanations for limiting enforcement to reversion include the negotiation costs that dispute resolution mechanisms carry (Keohane, Reference Keohane1984; Koremenos et al., Reference Koremenos, Lipson and Snidal2001; Koremenos, Reference Koremenos2005; Carrubba, Reference Carrubba2009) and the possibility that enforcing compensation is sometimes too difficult (Downs and Rocke, Reference Downs and Rocke1995; Barrett, Reference Barrett1999). The argument advanced here is particularly notable, however, because it operates even if strong sanctions are enforceable and do not carry high negotiation costs. Additionally, it can explain reversion even if compensation is easier to enforce than reversion. But the argument also does not contradict the existing explanations in any way, and indeed the results that favor reversion are stronger if the compensation mechanism is costly or difficult to enforce.
These results can inform the debate on enforcement and capacity building as avenues to international compliance (Chayes and Chayes, Reference Chayes and Chayes1995; Downs et al., Reference Downs, Rocke and Barsoon1996; Tallberg, Reference Tallberg2002). If the incentive to build capacity depends on the enforcement mechanism, it is not possible to understand one without understanding the other. This finding suggests that empirical and theoretical future research should integrate insights from both schools and serves as a warning against favoring one line of reasoning over the other in policy formation.
The argument is also relevant to the broader relationship between distributional conflict and enforcement. Fearon (Reference Fearon1998) argues that while a large ‘shadow of the future’ facilitates enforcement because states assign higher cost to institutional breakdown, it creates incentives to engage in costly heavy-handed bargaining.Footnote 6 My argument shows that the choice of enforcement mechanism has direct implications for distributional conflict. Since the compensation mechanism results in ‘regressive foreign aid’ from the recipient to the donor, it is even possible that the recipient refuses to engage in costly international negotiations if the compensation mechanism is on the table. Thus, the compensation mechanism could prevent international cooperation. This is a stronger effect than an increase in bargaining cost, and it could explain why powerful states often prefer reversion over compensation.
The argument can inform the debate about the role of legitimacy in international cooperation (Young, Reference Young1989; Chayes and Chayes, Reference Chayes and Chayes1995; Hurd, Reference Hurd1999; Wendt, Reference Wendt1999; Clark, Reference Clark2003; Thompson, Reference Thompson2006; Chapman, Reference Chapman2007).Footnote 7 Although legitimacy appears to be an important determinant of compliance with international rules and standards, it is not obvious what the implications for the choice of enforcement mechanisms are. Should we consider reversion illegitimate because it imposes costs on an innocent state? According to my theory, this counterargument to reversion is often invalid because reversion prompts preference alignment ex ante and thus appears equitable. The compensation mechanism opens a window of opportunity for exploitation, so weak states and foreign publics concerned with the normative implications of international cooperation have good reasons to view reversionary enforcement as legitimate.
The relationship between enforcement and capacity building is also important for the political economy of development assistance. Recently, many scholars have argued that foreign aid could harm economic growth and democratization unless domestic institutions incentivize the recipient government to use resources for the provision of various public goods (Svensson, Reference Svensson2000; Easterly, Reference Easterly2002; Smith and Bueno de Mesquita, Reference Smith and Bueno de Mesquita2007; Bueno de Mesquita and Smith, Reference Bueno de Mesquita and Smith2009). If the reader accepts the notion that capacity building promotes good governance, it could be that for the population, as opposed to the government, capacity building – not foreign aid per se – is the real benefit of international cooperation. Then reversion is particularly desirable because it ensures that even a self-interested donor cooperating with an autocracy can produce valuable public goods.
The most important assumption underpinning the theoretical analysis is that the recipient cannot credibly threaten to terminate cooperation unless capacity building is forthcoming. If the recipient could condition cooperation on capacity building, an equilibrium would exist in which capacity building occurs under compensation enforcement. But given the asymmetric power relationship between the donor and recipient, the range of circumstances in which such bargaining tactics can be successful appears narrow. This boundary condition is also useful because it produces a falsifiable empirical hypothesis that can be operationalized against data on relative bargaining power.Footnote 8
The analysis is robust to such variations as introducing multiple donors and recipients. As long as compliance is imperfectly observable, the fundamental problem of responding to perceived compliance failure remains intact. This problem is also present even if the donor holds ‘altruistic’ motivations and gives foreign aid to improve welfare in the recipient country. If the altruistic motive is strong enough, however, the commitment problem that I have identified could disappear because the donor holds an intrinsic preference for capacity building.
Theoretical analysis has two counterintuitive empirical implications. First, reversion should be most common in issue areas that require capacity building, such as regulatory and judicial reform or environmental conservation, and if the recipient is a least developed country. While an empirical test is beyond the scope of this study, this result is particularly important in light of the current emphasis on conditionality in the allocation of foreign aid (Vreeland, Reference Vreeland2003; Stone, Reference Stone2008). While some form of conditionality is necessary to incentivize the recipient, capacity building requires that the donor cannot exploit the conditions to demand compensation from the recipient.
Second, reversion should be less common if the two states operate in a highly institutionalized and legalized environment, such as the European Union, where credible commitments are possible.Footnote 9 If the donor can commit to capacity building, reversion can be augmented with compensation to the advantage of donor. And the donor could even increase the provision of foreign aid in exchange to ensure that both parties benefit from the compensation mechanism. But all this is only possible if mutual commitment capacity is readily available.
To conclude, the analysis creates opportunities for progressive theoretical research in international politics. The simple setup that I have used offers an accessible and flexible platform for game-theoretic analyzes of international cooperation between weak and powerful states. The mechanics of the baseline model are simple, so it is easy to add such new elements as domestic or transnational actors to it (Keck and Sikkink, Reference Keck and Sikkink1998; Dai, Reference Dai2002). The model can be applied to various international cooperation problems and the rationalist premises can be relaxed to incorporate sociological or constructivist theories of international politics (Ruggie, Reference Ruggie1998; Hurd, Reference Hurd1999; Wendt, Reference Wendt1999; Checkel, Reference Checkel2001). Ideally, the theoretical analysis contributes to the research program on compliance with international agreements beyond the question that I have addressed.
