Electoral Incentives for Interparty and Intraparty Politics (I3) Project

Together with Brian F. Crisp, Santiago Olivella, and Guillermo Rosas, this project uses novel computational tools and a comprehensive and updated dataset on electoral systems to develop precise and transparent measures of both electoral systems’ interparty incentives—the Total Duvergerian Effect (TDE)—and intraparty incentives—Average Personalism (AP). These two simple quantities capture the extent to which a given system encourages the election of a limited number of large parties or a larger number of relatively smaller ones and the extent to which the lawmaking process will be conducted by unified, programmatic parties or by individually noteworthy politicians. Below, you can find more about the products related to this project.
