Introducing the response to sponsorship dataset: Determinants of responses by target states to state sponsors of rebel groups

Abstract

Empirical studies on the sponsorship of rebel groups have focused on understanding why and how supporter states help rebels, whether this engagement benefits the rebels, and the effects of sponsorship on the conflict outcomes. By comparison, the responses of target states to sponsorship behavior have been neglected despite the possibility of interstate crises, disputes, and conflict due to the sponsorship. This study introduces a new dataset, the Response Sponsorship Dataset (RSD), which measures target states’ responses toward state sponsors of rebel groups intending to terminate the sponsorship. The data includes information on the responses of 58 target states to 102 supporter states concerning the support of 150 rebel groups between 1991 and 2010, comprising 3719 observations. The RSD identifies diplomatic, economic, militarized, domestic, covert responses and inaction as target state responses as well as classifying them as coercive or non-coercive based on target states’ foreign policy engagements with sponsors. The RSD provides new opportunities for researchers and policymakers to analyze target responses with regards to conflict management and foreign policy as well as promising future research on support termination.
