Abstract:
History offers many examples of dictators who worsened their behaviour significantly over time (like Zimbabwe’s Robert Mugabe) as well as dictators who displayed remarkable improvements (like Jerry Rawlings of Ghana). We show that such mutations can result from rational behaviour when the dictator’s flow use of repression is complementary to his accumulated stock of wrongdoings. Interacting this complementarity with uncertainty over the dictator’s degree of impunity in relation to wrongdoing (such that the dictator becomes inclined to experiment along this dimension), produces an environment in which any individual rising to power can end up as either a moderate leader, or as a dreaded tyrant. Our model shows that dictators are more likely to derail with higher levels of divertible funds available, for example stemming from fungible aid inflows or from the exploitation of natural resources. It furthermore suggests that derailment is accidental and that such leaders suffer from ex-post regret. Consequently, increasing accountability can be in the interest of both the public and the dictator.
