Despite the relatively extensive research on pay levels and the consequences of income disparities, little is known about which reference groups people choose for comparative evaluation of personal income and why different selection patterns emerge. The aim of this paper is to dig deeper for...

This paper explores whether more generous social spending polices in fact lead to less income inequality, or if redistributive outcomes are offset by behavioral disincentive effects. To account for the inherent endogeneity of social policies with regard to inequality levels, I apply the System...

This paper investigates the link between the optimal level of non-financial firms' leverage and macroeconomic uncertainty. We develop a structural model of a firm's value maximization problem that predicts that as macroeconomic uncertainty increases the firm will decrease its optimal level of...

We evaluate the effect of the federal students' financial assistance scheme (BAfoeG) on enrolment rates into higher education by exploiting the exogenous variation introduced through a discrete shift in the repayment regulations. Supported students had to repay the full loan until 1990....

This paper analyzes the distribution of technical efficiency within manufacturing industries. Using a representative sample of 35,000 firms in 255 industries of the German cost structure census, technical efficiencies are estimated by applying a deterministic frontier production function with...

Using micro-level panel data of about 35,000 firms from the German Cost Structure Census, we analyze the differences of technical efficiency across industries. Technical efficiency is estimated by firms' fixed effects. One striking result is that the distribution of technical efficiency across...
