| Summary: | The R package Synth implements synthetic control methods for comparative case studies designed to estimate the causal e ects of policy interventions and other events of interest (Abadie and Gardeazabal 2003; Abadie, Diamond, and Hainmueller 2010). These techniques are particularly well-suited to investigate events occurring at an aggregate level (i.e., countries, cities, regions, etc.) and a ffecting a relatively small number of units.
Bene ts and features of the Synth package are illustrated using data from Abadie and
Gardeazabal (2003), which examined the economic impact of the terrorist conflict in the Basque Country.
