Economically highly developed countries are mostly democratic. But does this association constitute a causal relationship according to which democracy is a determinant of economic development? Or is it, conversely, economic development that paves the way for democratization? This paper gives an...

This paper attempts to add to the understanding of the causes for the differing recent developments in inequality in OECD countries. The similarity of shocks and technological changes affecting these countries suggests that interactions of these shocks and countryspecific institutions are...

This paper develops a model of equilibrium unemployment with (unobservable) endogenous on-the-job search and (partly unobservable) endogenous search behavior by firms. The model allows to analyze crowding-out of unemployed job seekers by endogenous on-the job search of employees, and the...

We propose a unified growth theory to investigate the mechanics generating the economic and demographic transition, and the role of mortality differences for comparative development. The framework can replicate the quantitative patterns in historical time series data and in contemporaneous...

This paper presents a theoretical and empirical analysis of the role of life expectancy for optimal schooling and lifetime labor supply. The results of a simple prototype Ben-Porath model with age-specific survival rates show that an increase in lifetime labor supply is not a necessary, nor a...

Geringqualifizierte haben in Deutschland ein weitaus höheres Risiko arbeitslos zu werden als Fachkräfte. Kann ein subventionierter Niedriglohnsektor - wie er derzeit im Bündnis für Arbeit diskutiert wird - zur Lösung ihres Arbeitsplatzproblems beitragen? In welchem Umfang werden...

This paper investigates whether the timing of rewards affects behavior in multi-stage contests. Abstracting from discounting, theory predicts that it is irrelevant for behavior whether agents are immediately rewarded for succeeding on a particular stage, or whether the reward is delayed until...

In corporate practice, incentive schemes are often complicated even for simple tasks. Hence, the way they are communicated might matter. In a controlled field experiment, we study a minimally invasive change in the communication of a well-established incentive scheme - a reminder regarding the...
