Presidential Institutions and Electoral Participation in Concurrent Elections in Latin America

Previous studies of voter turnout in Latin America have found weak and inconsistent evidence for the link between political institutions and electoral participation. In this article, I use data from an expanded dataset of voter turnout in Latin America (1980–2016) to show that institutions do have an impact on citizens’ decisions on whether or not to participate in concurrent elections. Whereas previous studies analyzed the effect of legislative institutions on voter turnout, this article estimates a series of models that demonstrate the impact of presidential institutions and the political context surrounding presidential elections on electoral participation. The findings suggest that when first-order (presidential) and second-order (legislative) elections take place concurrently, electoral participation is influenced primarily by presidential institutions (term length, presidential powers, and electoral rules) and the electoral context in which the presidential elections take place (effective number of presidential candidates)
