The confluence of factors driving urban growth is highly complex, resulting from a combination of ecological and social determinants that co-evolve over time and space. Identifying these factors and quantifying their impact necessitates models that capture both why urbanization happens as well...

The behavioural response with respect to actuarial adjustments in the German public pension system is analysed. The introduction of actuarial adjustments serves as a source of exogenous variation to estimate discrete time transition rates into retirement. The analysis is conducted on...

By the mid-19th century, following the Prussian mining reform, German miners‘ combined mutual health and pension funds took on the characteristics of social insurance and underwent a concentration process driven by mergers, liquidations, and unequal internal growth. This paper investigates the...

We model the log-cumulative baseline hazard for the Cox model via Bayesian, monotonic P-splines. This approach permits fast computation, accounting for arbitrary censorship and the inclusion of nonparametric effects. We leverage the computational efficiency to simplify effect interpretation for...

This paper studies how stress affects the mortality risk. Using a flexible approach and allowing for timevarying treatment effects, I find no impact of stress on the short-run mortality risk but a substantially increase in the long-run. The effects are especially pronounced for men. I provide...

Using a large panel data set of German manufacturing establishments, this paper investigates the impact of competition on training incidence as well as on the number of trained workers. According to theory, one would expect a negative relationship between product market competition and firms'...

Using establishment data covering the time period 1997 to 2007, this paper investigates trends of employer-sponsored further training in Germany, with a focus on the share of establishments that undertake training investments. I find an increasing trend for West and East German establishments...

Assuming a two-period model with endogenous choices of labour, education, and saving, it is shown to be second-best efficient to deviate from Ramsey's Rule and to distort qualified labour less than nonqualified labour. Furthermore, if the earnings function displays constant elasticity, the...

This paper evaluates the impact of a training voucher program on establishments' investments in further training. The voucher program that was implemented in the German federal state of North Rhine-Westphalia increased training incentives for employees in small and medium-sized establishments by...

This study analyzes the relationship of individual risk attitudes and occupational sorting with respect to occupational earnings risk. By using the German Mikrozensus, a precise measure for earnings risk is computed as the occupation-wide standard deviation of wages. Following the procedure...
