The Origins of Institutional Crises in Latin America

Institutional instability and interbranch crises pose a fundamental challenge to democracies in Latin America and the developing world more generally. Combining a standard game theoretic model of crisis bargaining with a unique dataset on courts, executives, and legislatures for 18 Latin American countries between 1985 and 2008, the article develops a strategic account of how interbranch crises emerge and evolve. In addition to providing the first systematic picture of the frequency, type, and location of interbranch crises for the region, the article demonstrates that the decision to initiate an interbranch crisis is influenced by the allocation of institutional powers, public support for the targeted branch, and the expectations of success based on recent experiences. Building on these results, the article identifies several novel directions for future research on institutional instability.
