Non-democracies are seen as inherently unstable because of the high frequency of irregular and often-violent leadership turnovers. Our tractable stochastic game model investigates authoritarian stability and instability by portraying a world in which dictators are forced to tolerate threatening lieutenants because they are skillful at overcoming existential threats (shocks) to the regime. This unavoidable choice allows lieutenants to build up their own power bases, planting the seeds of various forms of authoritarian instability, including purges, coups, and civil war. Our model predicts, first and foremost, that changes in the frequency and severity of exogenous threats can have a profound impact on political stability. Contrary to research on the trade off between competence and loyalty, our model shows that when threats to the regime are existential and purges are an option, the dictator will always prefer to employ a competent lieutenant. Also, surprisingly, even with minimal institutional guarantees, we find that authoritarian regimes can be quite stable if the dictator and the lieutenant need each other for their unique skills in the face of major challenges. However, in accordance with the existing literature, credible institutions to ensure the welfare of ousted officials do, indeed, reduce the chance of internal conflict.
