It has been ten years since the release of the first version of the TIES data set. In this Chapter, we present a description of the data set and discuss the contributions to our understanding of economic sanctions that have followed from its use. There are four sections: First, we briefly explain the motivation behind and rationale for the data collection effort. Second, we provide a brief description of the data set and the data collection methods we followed. Third, we discuss a number of the published findings, by ourselves and others, that have been based on the data. Finally, we identify a number of important questions that cannot be addressed, or addressed well, using the data.
