Regime Legacies and Levels of Democracy: Evidence from Latin America

During the third wave of democratization, all Latin American countries except Cuba have had competitive political regimes, but the quality or level of democracy has varied significantly across countries and over time. One of the best predictors of this variance across countries and time is each country's experience with competitive politics before 1978. Even controlling for a wide range of other explanations, countries with more democratic heritages before 1978 have higher levels of democracy in the contemporary period. This finding, in turn, raises another question: what accounts for the effects of past levels of democracy on the post-1978 period? A hybrid fixed-effects model shows that democratic trajectories are institutionalized through political parties and judicial institutions. Countries that had institutionalized parties under democracy and supreme court justices who served under democracy in the pre-1978 period have been more able to build high-level democracy in the contemporary period.
