Cross-time behaviour of the chilean congress: Growth or stagnation of its influence

This research examines the cross-time behaviour of Chilean legislature from 1990 to 2009, studying the variables that influence their levels of productivity. It is noted that these are not homogeneous over the years, considering two main explanations: the first is the existence of certain political cycles -the first year of government and parliamentary elections- and the second is a long-term institutional process understood as the accumulation of democratic experience in Congress. These explanatory variables are tested through a logistic regression model, which suggests that under these conditions and institutional processes exist a greater legislative productivity in Congress, functioning as a coherent and coordinated body.
