Economic sanctions are a versatile instrument of statecraft used by states to try to influence the behavior of foreign actors by threatening or restricting customary cross-border trade or financial flows to an intended target. Examples of economic sanctions are retaliatory tariffs imposed in trade disputes and the complete cessation of economic flows aimed at undermining a certain regime. The importance of economic sanctions to policy makers has spawned a substantial amount of scholarly work dominated by two questions: whether sanctions “work” and whether states should use them. The long-running scholarly debate about whether sanctions work is essentially a dispute over how to classify cases. However, comparing cases of success and failure is problematic, in part because the very notion of what constitutes the successful use of sanctions is not clear and policy makers rarely seek to influence a single target or pursue a single policy goal when using sanctions. One of the most promising developments in the literature has been the increasing use of game theory to analyze sanctions, but this approach does not adequately determine the appropriateness of sanctions as a policy instrument. Sanctions research should focus instead on the basic strategic dynamics of the sanctions episode in order to identify those factors that contribute most strongly to the effective use of sanctions and to enable policy makers to understand more about the consequences of using sanctions as an instrument of statecraft.

Peace research is a component of the field of international relations (IR) that focuses on the causes of war and violence as well as the conditions of peace. The origins of peace research can be traced to the works of Plato, Thucydides, Hugo Grotius, Thomas Hobbes, and Immanuel Kant. The central debate in peace research revolved around the question of whether peace is to be defined simply as the absence of war and direct violence (“negative peace”) or the whether the concept encompasses both the absence of war and direct violence plus the presence of social justice (“positive peace”). Three primary waves of peace studies worldwide since its beginnings between the world wars can be identified: the first wave, roughly from the 1930s to 1960s, focused largely on the causes of war; the second wave was concerned with radicalization and democratization of peace studies; and the third wave saw the rise of two dominant fields—those of nuclear weapons, arms control and disarmament, and conflict resolution/management. During the 1990s, there was a renewed attention to research on topics such as sanctions, peacemaking, the concept of a culture of peace, environment, development, and conflict. Peace research and peace studies have in some ways brought about a transformation not only of dominant power structures, but also of the very concept of power itself. However, there are areas that need improvement, such as developing alternatives to armed conflict and injustice.
