How does domestic politics affect international cooperation? Even though classic work on international relations already acknowledges the central role of domestic politics in international relations, the first generation of scholarly work on international cooperation focused almost exclusively on the international sources of cooperation. Theories that explicitly link domestic politics and international cooperation did not take a more prominent place in the scholarly work on international cooperation until the late 1980s.
Recent research analyzes how interests and institutions at the domestic level affect the cooperation of governments at the international level. The analysis is structured along a political economy model, which emphasizes the decision making calculus of office-motivated political leaders who find themselves under pressure by different societal groups interested in promoting or hindering international cooperation. These pressures are conveyed, constrained, and calibrated by domestic institutions, which provide an important context for policy making, and in particular for the choice to cooperate at the international level. This standard political economy model of domestic politics is embedded within models of international cooperation, which entail decisions by governments about (a) whether to cooperate (and to comply with international agreements), (b) how to distribute the gains and costs from cooperation, (c) and how to design cooperation as to maximize the likelihood that the public good will be provided.
Domestic politics is significant to explain all aspects of international cooperation. The likelihood that governments engage in international cooperation does not only depend on international factors, but is also and sometimes predominantly driven by the demands of societal groups and variations in institutional structures across countries. Domestic factors can explain how governments behave in distributive negotiations, whether they can achieve advantageous deals, and if negotiations succeed to produce an international collective action. They also contribute to our understanding about whether and how governments comply with international agreements, and consequently, how the design of international institutions affects government compliance. More recently, scholars have become interested in the democratic responsiveness of governments when they cooperate at the international level. Whereas research is still sparse, emerging evidence points to responsive conduct of governments particularly when international cooperation is politicized at the national level.
