Existing studies hold that Latin America's market turn has had a demobilizing effect on collective political activity despite the presence of democracy. However, recent work has documented the revival of protest in the region, emphasizing the repoliticization of collective actors in the wake of economic liberalization, especially when democracy is present. This article expands the theoretical scope of the repoliticization perspective, providing the most comprehensive test of the demobilization and repoliticization hypotheses to date. Using time-series data from seventeen Latin American countries, the article confirms the repoliticization view by showing that protest increases with economic liberalization in democratic settings.
