Political Parties and Government Coalitions in the Americas

This paper focuses on the process of coalition formation in presidential systems. It shows that party positions and institutions influence the formation of government coalitions. We argue that presidents will tend to include parties positioned close to their policy positions in their cabinets, and will be more inclined to do it when relative institutional authority is more advantageous to congress. We corroborate our arguments with data from 13 presidential countries in the Americas.
