O quanto as preferências ideológicas dos parlamentares impactam nos resultados legislativos? O caso da Câmara dos Deputados entre 2003 e 2018

Abstract

The Federal deputies are immersed in a dense network of influences, and it‟s very difficult to accurately measure how much parties, voters, interest groups, and personal ideological positions impact their decision. This research proposes three empirical tests aiming to elucidate the main factors that influences theses preferences during the period between 2003 and 2018. The first one is an analysis of the factors that condition the presence of the chamber‟s members in the roll-call votes. The second is the estimation of the idealpoints, evaluating the explanatory power of the government-opposition cleavage. Finally, it‟s analyzed data from the Brazilian Legislative Survey (PLB), 2013 edition, on the opinion of legislators regarding important aspects of Brazilian political economic policy. The results support the argument that the chamber‟s members base their actions on both purely electoral calculations and on their views on the policies under discussion in Congress.
