• Evaluating the Effect of the Ideology of Governing Coalitions on Regional Integration Arrangements, with Rafael Magalhães 
Does the ideology of governing coalitions play a decisive role in determining a country's position towards regional integration arrangements (RIA)? The literature suggests that ideology does matter and may be a reliable predictor of a country's behavior in such arrangements. Accordingly, left-wing coalitions would be more prone to support a political dimension of regional integration. On the other hand, right-wing coalitions would be more concerned with measures to improve trade and financial cooperation. Although this view is shared by many, there is little empirical evidence to suggest that. For that reason, we have formulated a set of hypotheses to empirically evaluate the validity of this argument. First, using a data-set from 1960 to 2004, we analyzed the impact of the ideology of the governing coalition on the likelihood of it participating in RIA. Second, we evaluated if right and left-wing coalitions display distinct levels of commitment towards RIA. Finally, working with an original data-set on South American countries from 1991 to 2013, we estimated the impact of the ideology on trade flow with regional partners.
