Preemptive multipartism and democratic transitions
2025-12-19
Scholars debate whether the presence of multiple parties in the legislature stabilizes dictatorships or promotes their demise. We show that authoritarian regimes face a dilemma: allowing for multipartism reduces the risk of bottom-up revolt, but facilitates protracted top-down democratization. Concessions to the opposition diminish the long-term benefits of authoritarian rule and empower regime soft-liners. We test our theory in Latin America—a region with a broad range of autocracies —using survival models, instrumental variables, random forests, and two case studies. Our theory explains why rational autocrats accept multipartism, even though this concession may ultimately undermine the regime. It also accounts for democratic transitions that occur when the opposition is fragmented and without a stunning authoritarian defeat.
