We estimate the effect of age of school entry on educational attainment using three different data sets for Germany, sampling pupils at the end of primary school, in the middle of secondary school and several years after secondary school. Results are obtained based on instrumental variable...

There is an ongoing discussion in Germany about the implementation of tax credits in order to reintegrate low-skilled workers into the labor market. This paper aims at analyzing the policy instrument of tax credits in a theoretical model that systematically compares its costs and benefits in the...

We estimate short, medium, and long-run individual labor market effects of training programs for unemployed by following program participation on a monthly basis over a tenyear period. Since analyzing the effectiveness of training over such a long period is impossible with experimental data, we...

This paper studies if the consumption-based asset pricing model can explain the cross-section of expected returns. The CRRA model and several refinements (habit persistence and idiosyncratic shocks) all imply that the conditional expected return is linearly increasing in the asset's conditional...

This note argues that nonparametric regression not only relaxes functional form assumptions vis-a-vis parametric regression, but that it also permits endogenous control variables. To control for selection bias or to make an exclusion restriction in instrumental variables regression valid,...

This paper analyzes the effects of firing costs in a broader setup than what is usually done, allowing for on-the-job training. By doing so the traditional analysis is extended with respect to two points: On the one hand firing costs clearly increase firm training because worker and firm are...

Survey and option data are used to take a fresh look at the equity premium puzzle. Survey data on equity returns (Livingston survey) shows much lower expected excess returns than ex post data. At the same time, option data suggests that investors perhaps overestimate the volatility of equity...

The routine way of anticipating the effects of the corporate (profit) tax on investments and location choice is to calculate the effective marginal and average tax rates. This paper introduces a model of monopolistic competition to show how investment on the extensive and intensive margins...

Depending on the definition of the tax base, the statutory corporate tax rate implies rather different measures of effective average and marginal tax rates. This paper develops a model of a monopolistically competitive industry with extensive and intensive business investment and shows how these...

In Germany, there is currently a discussion about the implementation of penalty charges if firms refuse to offer apprenticeship training positions to school graduates. This paper aims at analyzing the policy instrument of penalty charges by a theoretical model that systematically compares its...
