Could the literature on the economic determinants of sanctions be biased?

The economic theory on economic sanctions gives strong indications that success depends positively on pre-sanction trade linkage and prior relations and negatively on sanction duration. However, the empirical literature has not arrived at consensus regarding these factors. Our research puzzle is the observation that despite more than three decades of empirical research on economic sanctions no consensus has yet emerged on the sign and significance of the impact of the key variables that theoretically determine the success of economic sanctions. In our research we explore reasons for the heterogeneity of the findings in the literature and the persistence nature of the debate.
