The General Agreement on Tariffs and Trade (GATT) and the World Trade Organization (WTO) have been touted as premier examples of international institutions, but few studies have offered empirical proof. This article comprehensively evaluates the effects of the GATT/WTO and other trade agreements since World War II. Our analysis is organized around two factors: institutional standing and institutional embeddedness. We show that many countries had rights and obligations, or institutional standing, in the GATT/WTO even though they were not formal members of the agreement. We also expand the analysis to include a range of other commercial agreements that were embedded with the GATT/WTO. Using data on dyadic trade since 1946, we demonstrate that the GATT/WTO substantially increased trade for countries with institutional standing, and that other embedded agreements had similarly positive effects. Moreover, our evidence suggests that international trade agreements have complemented, rather than undercut, each other.An earlier version of this article was presented at the 99th Annual Meeting of the American Political Science Association, Philadelphia, August 28–31, 2003.

Security relations between states vary along a continuum from anarchic alliances to hierarchic empires. This continuum, in turn, is defined by the parties' rights of residual control. The state's choice between alternatives is explained in a theory of relational contracting as a function of the expected costs of opportunism, which decline with relational hierarchy, and governance costs, which rise with relational hierarchy. A comparison of early postwar relations between the United States and Western Europe and the Soviet Union and Eastern Europe illustrates the theory.

How effective is terrorism? This question has generated lively scholarly debate and is of obvious importance to policy-makers. However, most existing studies of terrorism are not well equipped to answer this question because they lack an appropriate comparison. This article compares the outcomes of civil wars to assess whether rebel groups that use terrorism fare better than those who eschew this tactic. I evaluate the advantages and disadvantages of terrorism relative to other tactics used in civil war. Because terrorism is not a tactic employed at random, I first briefly explore empirically which groups use terrorism. Controlling for factors that may affect both the use of terrorism and war outcomes, I find that although civil wars involving terrorism last longer than other wars, terrorist rebel groups are generally less likely to achieve their larger political objectives than are nonterrorist groups. Terrorism may be less ineffective against democracies, but even in this context, terrorists do not win.

In recent years, there is growing interest in the study of cross-national policy convergence. Yet we still have a limited understanding of the phenomenon: Do we observe convergence of policies at all? Under which conditions can we expect that domestic policies converge or rather develop further apart? In this article, we address this research deficit. From a theoretical perspective, we concentrate on the explanatory power of three factors, namely international harmonization, transnational communication, and regulatory competition. In empirical terms, we analyze if and to what extent we can observe convergence of environmental policies across twenty-four industrialized countries between 1970 and 2000. We find an impressive degree of environmental policy convergence between the countries under investigation. This development is mainly caused by international harmonization and, to a considerable degree, also by transnational communication, whereas regulatory competition does not seem to play a role.

This article uses a rationalist approach to explain the international socialization of Central and Eastern Europe to liberal human rights and democracy norms. According to this approach, socialization consists in a process of reinforcement, and its effectiveness depends on the balance between the international and domestic costs and benefits of compliance over an extended period of time. EU and NATO accession conditionality has been a necessary condition of sustained compliance in those countries of Central and Eastern Europe that violated liberal norms initially. The pathways and long-term outcomes of international socialization, however, have varied with the constellations of major parties in the target states. Whereas conditionality has been effective with liberal and mixed party constellations, it has failed to produce compliance in antiliberal regimes. In the empirical part of the article, these propositions are substantiated with data on the development of liberal democracy in Central and Eastern Europe and case studies on Slovakia and Latvia.For useful comments on earlier versions, I thank the participants of the IDNET workshop seminars, especially Jeff Checkel, Matthew Evangelista, Judith Kelley, Thomas Risse, and Marianne van de Steeg.

The study of regional integration, of how national units come to share part or all of their decisional authority with an emerging international organization, is one of the areas of political inquiry in which a cumulative research tradition has developed. Previous paradigms are scrutinized critically in new settings; replications are made and even encouraged; new concepts, hypotheses, and measures are suggested and incorporated without obliterating past work. Under these conditions theoretical formalization may play a particularly fruitful role.

Scholars and policymakers generally assume that multilateral cooperation is a necessary condition for economic sanctions to be of any use. However, previous statistical tests of this assumption have shown that sanctions are more successful with lower levels of cooperation. This puzzle calls into question established theories of economic statecraft as well as theories of international cooperation. In this article I test possible explanations for the ineffectiveness of multilateral cooperation on sanctions events using James Fearon's (1998) breakdown of cooperation into bargaining and enforcement phases as a framework for discussion The empirical results show that when multilateral economic sanctions fail, their failure is due to enforcement, not bargaining problems Without the support of an international organization, cooperating states backslide from promises of cooperation Backsliding occurs because of domestic political pressures and uncertainty about the intentions of the other sanctioning countries; backsliding causes an initial burst of cooperative behavior to decay over time. Without institutional support, cooperation is worse than useless—it is counterproductive. This result suggests that international cooperation is a more fragile equilibrium than previously thought but undercuts realist arguments that international organizations are unimportant.

The concepts of regimes and learning have been developed in the Liberal theory of international relations, but their application has been mostly in the area of international political economy. U.S.–Soviet relations are generally explained solely in terms of Realist theory. The dichotomy is unfortunate because both strands of theory have something to contribute. Although the injunctions of an overall regime do not govern the U.S.–Soviet security relationship, it is possible to identify the injunctions and constraining effects of regimes in subissues of the security relationship. In five areas of the nuclear relationship (destructive power, control problems, proliferation, arms race stability, and deterrent force structure), it is possible to identify different degrees of learning and to see how such learning affects and is affected by the development of regimes. Looking at the U.S.–Soviet security relationship in terms of learning and regimes raises new questions and opens a research agenda which helps us to think more broadly about the processes of political change in this area.

Three perspectives dominate debate over the relationship between globalization and the welfare state in industrialized countries: that globalization constrains the welfare that hitherto legitimated openness, that globalization still sparks demands for welfare while opening few forces to flee or fight against it, and that openness has little effect on welfare. A closer look at the “globalization” and “welfare” aggregates on which most scholars focus, however, reveals varying politics connecting different elements of globalization and welfare that may help reconcile this debate. First, compared to general trade openness, low-wage competition may spark stronger pressure to expand and less pressure to constrain welfare compensation. Second, all kinds of openness affect vulnerable and thriving groups in ways that differ across social policies, especially training and relocation benefits compared to benefits for youth dependents and the elderly. Consequently, different faces of openness may spark predictably different politics that spur some aspects of welfare, retrench others, and have little effect on still others. Panel data for eighteen OECD countries supports this argument.

I offer an explanation for the widespread diffusion of neoliberal tax policies in the developed democracies. After accounting for the policy influences of commonly experienced domestic and international forces, I consider several plausible paths of diffusion of neoliberal tax structure. My central argument is that the highly visible 1980s market-conforming tax reform in the United States should be especially important in shaping subsequent tax policies in other polities. There are substantial reasons to believe, however, that domestic political and institutional forces will shape policymaker assessment of the benefits and costs of neoliberal reforms: the strength of right parties and the degree to which the median voter has moved right should condition adoption of neoliberal tax policy; the institutions of national and sector-coordinated capitalism should also slow the enactment of neoliberal tax reforms. I assess these arguments with empirical models of 1981–98 tax rates on capital in sixteen nations. I find that changes in U.S. tax policy influence subsequent reforms in other polities; in the long term, all nations move toward the U.S. neoliberal tax structure. Analysis also shows, however, that the short-term responsiveness to U.S. tax reforms is notably greater where uncoordinated market institutions are dominant. Theory and extensive qualitative and quantitative evidence indicate that pressures to compete for mobile assets, as balanced against the economic and political costs of adoption, anchor the process of diffusion of neoliberal tax policy. There is little evidence for the view that systematic policy learning or social emulation drove tax policy diffusion.Earlier versions of this article were presented at the Center for European Studies and Weatherhead Center for International Affairs, Harvard University; Center for International Studies, UCLA; and Yale University as well as the 2002 Annual Meetings of the American Political Science Association.

A central research question in international political economy concerns the influence of financial markets on government policy outcomes. To what extent does international capital mobility limit government policy choices? I evaluate the relationship between international financial markets and government policy outcomes, with a focus on the government bond market in developed democracies. Evidence includes interviews with financial market participants and a cross-sectional time-series analysis of the determinants of interest rates. This evaluation suggests that governments of developed democracies face strong but narrowly defined financial market pressures. Financial market participants are concerned with a few macroeconomic policy indicators, including inflation rates and government deficit/GDP ratios, but not with micropolicy indicators, such as the distribution of government spending across functional categories. In these areas, governments retain policymaking autonomy. I conclude by exploring the role of financial market influences within domestic politics and offering suggestions for further research.

Regimes are harder to establish in the security area than they are in the economic realm because of the inherently competitive cast of many security concerns, the unforgiving nature of the problems, and the difficulty in determining how much security the state has or needs. Nevertheless, there is at least one example of a functioning security regime—the Concert of Europe. Under the Concert the great powers sharply moderated their individualistic and competitive policies and exercised restraint in the expectation that others would reciprocate. The self-interest that they followed was broader and longer-run than usual. The Balance of Power, however, is a regime only if the restraints are internal, as Kaplan implies, as contrasted with Waltz's formulation in which states restrain each other. Current superpower relations should not be considered a regime because the principles, rules, and norms have little autonomy but instead can be best understood as quite direct reflections of the states' power and interests.

Preferential trading arrangements (PTAs) have spread widely over the past fifty years. During the same era, multilateral openness has grown to unprecedented heights, spurred by the General Agreement on Tariffs and Trade (GATT) and its successor, the World Trade Organization (WTO). If the cornerstone of the manifestly successful multilateral regime is nondiscrimination, why have its members increasingly resorted to preferential liberalization? We argue that developments at the heart of GATT/WTO encourage its members to form PTAs as devices to obtain bargaining leverage within the multilateral regime. Specifically, the growth in GATT/WTO membership, the periodic multilateral trade negotiation rounds, as well as participation and, especially, losses in formal GATT/WTO disputes, have led its members to seek entrance into PTAs. Conducting the first statistical tests on the subject, we find strong evidence in support of this argument.

Modern states have constructed a multiplicity of issue-specific regimes to facilitate collective action. The majority of these institutions are specific instances of the deeper institutional practices that structure modern international society, notably the fundamental institutions of contractual international law and multilateralism. Two observations can be made about fundamental institutions. First, they are “generic” structural elements of international societies. That is, their practice transcends changes in the balance of power and the configuration of interests, even if their density and efficacy vary. The modern practices of contractual international law and multilateralism intensified after 1945, but postwar developments built on institutional principles that were first endorsed by states during the nineteenth century and structured international relations long before the advent of American hegemony. Second, fundamental institutions differ from one society of states to another. While the governance of modern international society rests on the institutions of contractual international law and multilateralism, no such institutions evolved in ancient Greece. Instead, the city-states developed a sophisticated and successful system of third-party arbitration to facilitate ordered interstate relations. This institution, which operated in the absence of a body of codified interstate law, is best characterized as “authoritative trilateralism.”

If different parties control the U.S. Congress and White House, the United States may maintain higher import protection than otherwise. This proposition follows from a distributive politics model in which Congress can choose to delegate trade policymaking to the President. When the congressional majority party faces a President of the other party, the former has an incentive to delegate to but to constrain the President by requiring congressional approval of trade proposals by up-or-down vote. This constraint forces the President to provide higher protection in order to assemble a congressional majority. Evidence confirms that (1) the institutional constraints placed on the President's trade policymaking authority are strengthened in times of divided government and loosened under unified government and (2) U.S. trade policy was significantly more protectionist under divided than under unified government during the period 1949–90.

How can authoritarian states credibly signal their intentions in international crises? Nationalist, antiforeign protests are one mechanism by which authoritarian leaders can visibly demonstrate their domestic vulnerability. Because protests in authoritarian states are risky and costly to repress, the decision to allow or stifle popular mobilization is informative. The threat of instability demonstrates resolve, and the cost of concession increases the credibility of a tough stance. The danger of instability and escalation increases foreign incentives to make concessions and preserve the status quo. This logic helps explain the pattern of authoritarian tolerance and repression toward nationalist protest. A case study of two U.S.-China crises shows how China's management of anti-American protests affected U.S. beliefs about Chinese resolve.

Heightened economic interdependence in recent years is commonly argued to have generated great pressures for convergence in economic policies across the advanced industrial democracies. Interdependence has clearly had a great impact on the types of economic policies that governments can pursue: they have been unable to pursue independent fiscal and monetary policies since the mid-1970s. Furthermore, all governments have been forced to attempt to promote the competitiveness of national goods and services in world markets and to increase the speed and efficiency with which national producers adjust to changes in global markets. There are, however, different policies consistent with these goals. Statistical analyses of economic policies since the mid-1970s show that governments of the left and the right continue to be able to enact distinctive supply-side policies that promote competitiveness and flexible adjustment and simultaneously further their partisan objectives.

How is it, that among the countless technological innovations in weaponry, chemical weapons stand out as weapons that carry the stigma of moral illegitimacy. To provide an adequate account of the prohibitionary norm against chemical weapons use, one must understand the meanings that have served to constitute and delegitimize this category of weapons. Such an account is provided by genealogy, a method that examines the interpretive practices around which moral orders are constructed and behaviors are defined as normal or unacceptable. The genealogical method yields insights that illuminate neglected dimensions of the chemical weapons taboo: namely, the roles that contingency, domination, and resistance have played in the operation of this norm as a symbol of “uncivilized” conduct in international relations.

This article explores the constructivists' institutional socialization hypothesis, positing that intergovernmental organizations (IGOs) make member-state interests more similar over time, thus promoting interest convergence. We first show how this hypothesis can be tested systematically using relatively new data on dyadic interest similarity and joint structured IGO membership, and then we conduct a series of empirical tests. Our results show strong statistical support for the institutional socialization hypothesis, using both global and more restricted regional samples. We also demonstrate how our results are consistent with a longer-term socialization process and cannot be explained by the short-term effect of institutional information. Finally, we show some limits to the institutional socialization hypothesis. Unstructured IGOs reveal no effect in promoting member-state interest convergence. Following recent theory arguing that great powers in the international system often use IGOs for coercive means, we find that institutional socialization gets weaker as the power imbalance within the dyad grows.Thanks to Chuck Boehmer, Heather Elko McKibben, Kate Floros, Erik Gartzke, Chuck Gochman, Michael Goodhart, Yoram Haftel, Volker Krause, Dan London, Andrew Long, Ed Mansfield, Lisa Martin, Tim Nordstrom, Zeki Sarigil, Meg Shannon, Dan Thomas, Lora Viola, Basak Yavcan, and two anonymous reviewers for data, comments, and/or helpful suggestions.
