Abstract
Psychologists have long documented that we over-attribute people's actions to innate characteristics, rather than to luck or circumstances. Similarly, economists have found that both politicians and businessmen are rewarded for luck. In this paper, we introduce this "Fundamental Attribution Error" into two benchmark political economy models. In both models, voter irrationality can improve politicians' behavior, because voters attribute good behavior to fixed attributes that merit reelection. This upside or irrationality is countered by suboptimal leader selection, including electing leaders who emphasize objectives that are beyond their control. The error has particularly adverse consequences for institutional choice, where it generates too little demand for a free press, too much demand for dictatorship, and responding to endemic corruption by electing new supposedly honest leaders, instead of investing in institutional reform.
