Can paying politicians well reduce corruption? The effects of wages and uncertainty on electoral competition
通过实验室实验，研究了工资水平和不确定性（如人气冲击）如何影响政客的腐败行为（寻租），发现高薪在无冲击时能减少腐败，但冲击存在时效果复杂。
We investigate the effects of wages and uncertainty on political corruption as measured by rent-taking. First, our laboratory data show that contrary to standard theory, rent-taking is not independent of, but decreases with wages in the absence of popularity shocks. Second, the orthodox view that rent-taking is greater in the presence of popularity shocks, given wages, is not necessarily true. Third, we find that in the presence of popularity or ideological shocks rent-taking is increasing in the variance of the shock for given wages, and is decreasing in wages for a given variance of the shock. While our third finding is in line with the directional predictions of the Nash equilibria, the deviation from Nash is large when the variance of the popularity shock is high and wages are low. We show that the deviations can be explained using a Quantal Response Equilibrium approach and taking risk-attitudes into account.
