Research on the domestic politics of trade typically begins with a theory about who benefits from trade and who is harmed by it. The actors—for instance, firms, workers, or industries—who benefit from trade are expected to support liberalization while those who are harmed are expected to oppose liberalization. For individuals, exposure to globalization through the labor market—including the type of job, firm, or industry—is likely to be an important determinant of individuals’ preferences over policies governing the global economy. To understand the domestic politics of trade with respect to labor, therefore, it is important to ask two key questions. First, what explains the preferences of workers? Broadly, scholars can be divided between those that argue different economic factors (i.e., labor market consequences) explain attitudes toward free trade and those who argue that noneconomic factors (e.g., values, information) are the main drivers of attitudes. Empirical tests of these theories rely on survey data. Second, how do trade pressures influence elections and when do workers’ interests influence policy outcomes? Research on mass politics shows that workers’ interests with respect to trade shape not only support for incumbents in elections but also whether elected officials support free trade. Domestic institutions also play an important role in this process, with research suggesting that democracies and left-leaning governments implement trade policies that are more favorable to workers. Yet trade in the 21st century looks very different from trade 30 years ago. It no longer involves only (or even primarily) the exchange of final goods but also trade in intermediate goods and services. Trade is also closely linked to the production strategies of multinational firms, including offshoring. These fundamental changes in the nature of global economic activity have important implications for the how the interests of workers relate to those of their employers, and by extension the politics of trade. As a result, scholars are increasingly incorporating new models of trade into analysis of politics at the individual and aggregate levels.

Scholarship on the relationship between domestic institutions and foreign policy is driven by the assumption that a state’s domestic political arrangement can explain important aspects of its foreign policy behavior. Democratic domestic institutions, in particular, are thought to be significant for explaining an important set of outcomes. Research shows, for example, that democracies tend to cooperate with each other; uphold their commitments; make more effective threats; engage in fewer wars with each other (but do fight non-democracies quite frequently); perform better in the wars in which they are involved; and tend to fight wars of shorter duration. Studying the impact of democratic domestic institutions on foreign policy has developed along two broad lines. The first and most established approach is rooted in the basic distinction between democracies and non-democracies. In this view, democratic institutions constrain leaders in a way that produces distinct democratic foreign policy patterns. This approach has yielded a tremendous amount of research and insight into democratic foreign policy, but also suffers from several important shortcomings. One is that democracy tends to be correlated with a host of other variables, making it difficult to specify what exactly it is about democracy that explains certain foreign policy outcomes. A second and related critique of this approach is that it tends to treat democracy uniformly when in fact there is often great variation in democratic domestic institutions across cases. A second and more recent approach focuses on the differences among democracies and seeks to explain how this variation, in turn, creates variation in foreign policy behavior. Democracies differ in terms of their underlying institutional arrangements in a variety of ways, including whether they have presidential or parliamentary systems, autonomous or constrained executives, and open or closed institutions to modulate the flow of information between leaders and citizens, among others. Even within a country, there can be a different set of institutional constraints on democratic leaders depending on the given foreign policy instrument they seek to employ. Studying these variations and their impact on policy processes and outcomes provides great promise for further unpacking the relationship between domestic democratic institutions and foreign policy.

The question of how domestic institutions influence foreign policy decisions has a long history in the study of international relations. However, until recently most of this research has compared the foreign policies of democracies and autocracies, with little attention to the differences within autocracies. In recent years, a small but growing body of literature has examined constraints within autocracies, taking issue with the widespread image of authoritarian leaders as unconstrained and unaccountable. Although existing research on this topic is limited, it focuses on two general sources of constraint on authoritarian leaders: constraints imposed by regime insiders and constraints at the hands of the public. In regimes with a powerful domestic audience, insiders often have both the will and the means to punish their leader for foreign policy failures. Consequently, such regimes sometimes behave quite similarly to democracies. In general, regimes with powerful selectorates or domestic audiences appear more likely to pursue peaceful security policies, to win the military conflicts they do enter, to lose office in the aftermath of defeat in war, to sign trade agreements, to adopt floating exchange rates, and to cooperate internationally, compared to regimes lacking such elite constraints. Scholars remain divided, however, about the extent to which the backgrounds of members of the domestic audience (e.g., whether they stem from a military or civilian ranks) matter. Less research studies whether the public can constrain authoritarian leaders. However, research indicates that the public can sometimes exert constraints through elections or the threat of revolt, if to a lesser extent than regime insiders. For example, the threat of revolution can make leaders who fear violent removal less likely to make concessions to end a conflict. Furthermore, antiforeign protest can tie a regime’s hands, with both peaceful and violent consequences. In the economic realm, some research suggests that the threat of inequality-driven revolutions spurs autocrats to pursue free-trade agreements. Overall, the study of domestic constraints on foreign policy in authoritarian regimes is an emerging area of research, with numerous areas for future study.

States’ compliance with international law is a multicausal event, with variables operating at various levels of analysis, such as states’ incentives, regime type, issue area, strategic considerations, psychological perceptions, and level of enforcement. Recent scholarship on compliance with international law in general, and with international agreements in particular, has made great progress in uncovering some of the links between these factors, and in determining under what conditions we are more likely to see greater compliance, in what issue areas, and in explaining these variations.

A founding member state of the European Union (EU) and a major European institutional center, Luxembourg has been a consistently strong supporter of the further development of European integration, often acting to facilitate compromises at critical moments. Its European policy rests on a broad political consensus and enjoys strong support in national public opinion. However, the country has also defended key national priorities on occasion, such as the interests of the steel sector in the early phases of European integration or its taxation policy in the early 21st century. Historically, this openness toward cooperation can be explained by reference to Luxembourg’s long experience of cooperation with neighbouring countries. Luxembourg was a member of the Zollverein (German Customs Union) in the 19th century and formed an economic union with Belgium after the First World War. European policymaking in Luxembourg is characterized by a pragmatic and informal policy style. The comparatively limited size of the national bureaucracy allows for an ease of internal communication and coordination. The typically long tenures and broad remits of national officials coupled with their multilingualism facilitate their integration into European policy arenas, where they often play pivotal roles. Luxembourgish society is further highly “Europeanized.” As the country became one of the largest producers of steel in the world, it attracted high levels of immigration from other European countries. The economic transformation of the country from the 1980s onward—moving from an industrial economy to a service-based economy centered on the financial sector—would not have been conceivable without the parallel development and deepening of European integration. In 2018, foreigners made up 48% of the resident population of the country, with citizens of the other 27 EU member states accounting for around 85% of that foreign community. The country’s labor force is further heavily dependent on cross-border workers from the three surrounding countries. This unique national situation poses a range of distinctive policy challenges regarding both the national political system and the wider governance of an exceptionally dense network of cross-border relationships.
