These techniques are particularly well-suited to investigate events occurring at an aggregate level (i.e., countries, cities, regions, etc.) and affecting a relatively small number of units. Benefits and features of the <b>Synth</b> package are illustrated using data from Abadie and Gardeazabal (2003), which examined the economic impact of the terrorist conflict in the Basque Country.}, number={13}, journal={Journal of Statistical Software}, author={Abadie, Alberto and Diamond, Alexis and Hainmueller, Jens}, year={2011}, pages={1–17} }
