Distinguishing Between Influences on Brazilian Legislative Behavior

Ideal point estimators hold the promise of identifying multiple dimensions of political disagreement as they are manifested in legislative voting. However, standard ideal point estimates do not distinguish between ideological motivations and voting inducements from parties, coalitions, or the executive. In this article we describe a general approach for hierarchically identifying an ideological dimension using an auxiliary source of data. In the case we consider, we use an anonymous survey of Brazilian legislators to identify party positions on a left‐right ideology dimension. We then use this data to distinguish ideological motivations from other determinants of roll‐call behavior for eight presidential‐legislative periods covering more than 20 years of Brazilian politics. We find that there exists an important nonideological government‐opposition dimension, with the entrance and exit of political parties from the governing coalition appearing as distinct shifts in ideal point on this second dimension. We conjecture that the Brazilian president's control over politically important resources is the source of this dimension of conflict, which has recently become far more important in explaining roll‐call voting than the ideological dimension.     

The Link Between Voting and Life Satisfaction in Latin America

What is the relationship between voting and individual life satisfaction in Latin America? While studies of Western Europe suggest that voters are happier than nonvoters, this relationship has not been explored in the younger democracies of the developing world, including those of Latin America. Using multilevel regression models to examine individual‐level survey data, this study shows a positive correlation between voting and happiness in the region, noting, however, that the relationship is attenuated in those countries that have enforced compulsory voting. We then explore the causal direction of this relationship: while the existing literature points to voting as a possible determinant of individual happiness, it is also possible that happier individuals are more likely to vote. Three different strategies are used to disentangle this relationship. On balance, the evidence suggests that individual happiness is more likely to be a cause rather than an effect of voting in Latin America.
