Economic sanctions as an instrument of foreign policy: The role of domestic politics

Most studies of economic sanctions have concluded that they are ineffective as instruments of foreign policy. In a previous effort, we applied the spatial model of bargaining to the question of sanctions effectiveness to identify the‐conditions under which sanctions can be expected to “work.” In this paper, we refine that analysis by examining the impact of domestic politics in the state that is the target of the sanctions. Sanction episodes may be examples of two‐level games in which the domestic game within both parties affects the international game and vice‐versa. Here, we take a first cut of applying this approach to the analysis of sanctions effectiveness. We extend the spatial model to focus on how sanctions affect the internal political bargaining within the target state. From this, we determine how state policy should change (or not) as a result of the sanctions. We use the basic model to identify general hypotheses regarding the nature of sanctions and their effectiveness and we evaluate some of these hypotheses using cases in which the United States imposed sanctions on Latin American countries for human rights violations.
