In 1996, statutory sick pay was reduced for private sector workers in Germany. Using the empirical observation that trade union members are dismissed less often than non-members, we construct a model to predict how absence behavior will respond to the sick pay reform. We show that union members...

This paper analyzes optimal linear taxes on labor income and savings in a standard two-period life-cycle model with endogenous leisure demands in both periods and non-insurable income risks. Households are subject to skill shocks in both periods of the life-cycle. We allow for completely general...

This paper characterizes when the one-stage deviation IC constraints in the usual sense of dynamic mechanism design are sufficient. One can easily construct examples of when they are not sufficient. If the current state or the belief is not a sufficient summary statics of the agent's private...

The estimated amount of people affected by natural hazards stands at a staggering number of about 243 million people per year. While not all of the affected move across borders, international migration potentially provides an adaptation mechanism to natural hazards. The aim of this paper is to...

This paper analyses bargaining over an incentive compatible contract in a moral hazard framework. We introduce the Kalai-Smorodinsky bargaining solution and compare the outcome with the commonly applied Nash solution. Whether worker's effort is higher in the Nash or the Kalai-Smorodinsky...

This paper analyzes the effect of the removal of government guarantees on bank risk taking. We exploit the removal of guarantees for German Landesbanken which results in lower credit ratings, higher funding costs, and a loss in franchise value. This removal was announced in 2001, but...

This paper surveys tax haven legislation and links the literature on tax havens to the literature on asymmetric information. I argue that the core aim of tax haven legislation is to create private information (secrecy) for the users of tax havens. This leads to moral hazard and transaction costs...

We analyze the optimal contract in static moral hazard situations, where the agent's effort is not verifiable. We first present the main trade-offs of the principal-agent model. We cover the trade-off of incentives (motivation) vs. risk-sharing (efficiency), incentives vs. rents (when the agent...
