Abstract

This study questions the level of influence that different Latin American presidents have on the making of laws. In order to delimit this analysis, it is necessary to understand the factors that affect decision making in Latin American parliaments. Many of the theoretical approaches that tackle the study of decision making within legislative bodies maintain that the laws that arise from this decisional process, in addition to depending on the institutional organization of the parliament itself, depends on the political actors taking part, on their strategies when adapting to this institutional framework, and on their interests as well as on their collective and individual preferences.

The aim of this research is to verify the explanatory strength of these theories in Latin American countries. Thus, an analysis is made of the importance that the institutional factors—relating to regulatory design—and the party factors—relating to both the presence of the political parties in the parliament and government and the ideological attitudes shown by the legislators—have in the legislative performance of diverse Latin American presidents.
