Abstract

Using a unique dataset of German members of parliament with information on total earnings including outside income, this paper analyzes the politicians' wage gap (PWG). After controlling for observable characteristics as well as accounting for selection into politics, we find a positive PWG which is statistically and economically significant. It amounts to 40-60% compared to citizens with an executive position. Hence, we show that the widely held claim that politicians would earn more in the private sector is not confirmed by our data. Our findings are robust with respect to potential unobserved confounders. We further show that the PWG exceeds campaigning costs and cannot be justified by extraordinary workload. Hence, our results suggest that part of the PWG can be interpreted as rent extraction. This calls for a reform of the regulation of outside earnings, which account for a sizeable share of the wage premium.
