International Signaling and Economic Sanctions

Do economic sanctions serve international signaling purposes? A fully structural statistical model that employs a signaling game as a statistical model is used to investigate the existence of signaling effects of sanctions. Estimation results suggest that sanctions fail to work as a costly signal. The cheapness of sanctions prevents a target state from being able to distinguish a resolute sender state from a sender who is bluffing. When sanctions are imposed, a target rarely updates its initial evaluation of the sender state’s resolve, much less than when a military challenge is observed.     

Coercion,Information, and the Success of Sanction Threats

This article explores when and why sanction threats succeed in extracting concessions from the targeted country. We focus on two different, albeit not mutually exclusive, mechanisms that can explain the success of sanction threats. The first mechanism relates to incomplete information regarding the sanctioner's determination to impose sanctions and suggests that threats help to extract concessions by revealing the sanctioner's resolve. The second mechanism underscores the direct impact of common interest between the two countries and explains the success of sanction threats by the targeted country's greater dependence on this link between the two countries and the sanctioner's ability to exploit this dependence. We test the hypotheses using a new strategic structural estimator. Our results provide no evidence in favor of the informational hypothesis, while lending robust support for the coercive hypothesis.
