Abstract

The 1996 electoral reform in Uruguay separated national form the subnational elections. Both elections are held six months apart, but by different electoral systems: two round majority for presidential elections, and plurality for the elections of departmental mayors. In this context, parties that compete in the two elections are strictly the same and the electorates are practically identical. This makes it possible to compare the electoral results in each constituency with a system that encourages strategic behaviors and other that do not. The estimated results point out a robust reducing effect of the plurality system on the effective number of parties and show the effects of strategic behaviors of parties and voters under this electoral system.
