The Political Economy of Post-Inclusion Democracies: Incorporation, Cooperation, and Political Equilibria

Over recent decades, many Latin American democracies have expanded political participation, social rights, and redistribution, yet have simultaneously experienced rising discontent, policy volatility, and institutional fragility. This coexistence challenges standard political economy models that associate democratization with greater stability and accountability. This paper argues that incorporation—the expansion of effective participation in political and policymaking processes—alters the cooperation problem itself. While broader participation raises the potential gains from collective action, it also increases coordination costs and the institutional demands required to sustain self-enforcing cooperation. A simple model shows that as participation expands, the minimum level of institutional adaptation required for cooperation rises; when such adaptation lags, polities may become trapped in low-cooperation equilibria marked by polarization and short time horizons. Comparative case studies of Uruguay, Chile, Brazil, Argentina, Peru, and Venezuela illustrate how similar inclusionary processes generate divergent political trajectories depending on whether cooperative governance adjusts to expanded participation. Where cooperation is rebuilt, inclusion supports legitimacy and durable governance; where it is not, expanded voice yields instability and, in extreme cases, democratic breakdown.
