Research in political science has identified trust as an important variable for the emergence of cooperative social-political processes, but there are no empirical explorations in Latin American political science yet of the relationship between trust and other variables that are thought to affect cooperation in regional decisión-making arenas. This article contributes to addressing this limitation by examining the relationship between trust, exchange of resources, and perception of political influence among actors in 3 sub-national regions in Argentina. Results suggest that these variables are significantly related to each other, which
has implications for our understanding of how regional governance processes work. We discuss these implications in detail.
