This paper studies the performance of promotion tournaments with heterogeneous participants in two dimensions: incentive provision and selection. Our theoretical analysis reveals a trade-off for the tournament designer between the two goals: While total effort is maximized if less heterogeneous...

This paper shows that the incentive effects of heterogeneity may be positive rather than negative in dynamic contests with multiple stages. In particular, the well-studied adverse effects of heterogeneity in static interactions are compensated by positive continuation-value and selection...

This paper investigates empirically whether decision makers are forward looking in dynamic strategic interactions. In particular, we test whether decision makers in multi-stage tournaments take heterogeneity induced changes of continuation values and the ability of their immediate opponent into...

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...

Credence goods markets suffer from inefficiencies arising from informational asymmetries between expert sellers and customers. While standard theory predicts that inefficiencies disappear if customers can verify the quality received, verifiability fails to yield efficiency in experiments with...

Empirical literature on moral hazard focuses exclusively on the direct impact of asymmetric information on market outcomes, thus ignoring possible repercussions. We present a field experiment in which we consider a phenomenon that we call second-degree moral hazard - the tendency of the supply...

Evidence on behavior of experts in credence goods markets raises an important causality issue: Do "fair prices" induce "good behavior", or do "good experts" post "fair prices"? To answer this question we propose and test a model with three seller types: "the good" choose fair prices and behave...
