    Determinants of Sanctions Effectiveness: Sensitivity Analysis Using New Data
    (Taylor & Francis Group, LLC, 2013) Bapat, Navin A.; Heinrich, Tobias; Kobayashi, Yoshiharu; Morgan, T. Clifton
    In the literature on sanctions effectiveness, scholars have identified a number of factors that may contribute to sanctions success. However, existing empirical studies provide mixed findings concerning the effects of these factors. This research note explores two possible reasons for this lack of consistency in the literature. First, informed by the recent theories that suggest threats are an important part of sanctions episodes, we analyze both threats and imposed sanctions. Second, to lessen model dependency of empirical findings, we employ a methodology that permits us to check systematically the robustness of the empirical results under various model specifications. Using the newly released Threat and Imposition of Economic Sanctions data, our analyses of both threats and imposed sanctions show that two factors—involvement of international institutions and severe costs on target states—are positively and robustly related to sanctions success at every stage in sanctions episodes. Our analyses also identify a number of other variables that are systematically related to sanctions success, but the significance of these relationships depends on the specific model estimated. Finally, our results point to a number of differences at the threat and imposition stages, which suggests specific selection effects that should be explored in future work.

    Implementation of Economic Sanctions
    (2013-09-16) Kobayashi, Yoshiharu; Morgan, T. Clifton; Leeds, Brett Ashley; Stevenson, Randolph T.; Sickles, Robin
    This dissertation investigates implementation problems in economic sanctions and how a state's concerns about policy implementation affect its decisions and the outcomes of sanctions. This study builds on the premise that sanctions are carried out by firms within a sanctioning state, not the state itself. First, using a game-theoretical model, I show that firms' non-compliance with sanction policies not only undermines the effectiveness of unilateral sanctions, but also has a counter-intuitive effect on a sanctioning state's decision to impose sanctions. The model suggests that a state is more likely to impose sanctions when it anticipates firms' non-compliance. A number of empirical implications are derived from the model and corroborated with data. Second, this study also investigates a sanctioning state's decision to sanction multilaterally or unilaterally, and how its expectations about the enforcement of sanctions influence this decision. When the enforcement of unilateral sanctions is expected to be difficult, the state is more likely to sanction multilaterally, but only when it has enough resources and the bureaucratic capability to help other states enforce their sanctions. The empirical evidence also buttresses these theoretical results. This study highlights the importance of incorporating expectations about enforcement into a full understanding of the sanctions processes. The conclusion is that states' ability to influence firms' decisions at home as well as abroad is a crucial determinant of whether they impose, how they design, and the effectiveness of sanctions.

    Threat and imposition of economic sanctions 1945-2005: Updating the TIES dataset
    (Sage, 2014) Morgan, T. Clifton; Bapat, Navin; Kobayashi, Yoshiharu
    Recent research on economic sanctions has produced significant advances in our theoretical and empirical understanding of the causes and effects of these phenomena. Our theoretical understanding, which has been guided by empirical findings, has reached the point where existing datasets are no longer adequate to test important hypotheses. This article presents a recently updated version of the Threat and Imposition of Economic Sanctions dataset. This version of the data extends the temporal domain, corrects errors, updates cases that were ongoing as of the last release, and includes a few additional variables. We describe the dataset, paying special attention to the key differences in the new version, and we present descriptive statistics for some of the key variables, highlighting differences across versions. Since the major change in the dataset was to more than double the time period covered, we also present some simple statistics showing trends in sanctions use over time.
