This paper studies a novel dynamic principle agent setting with moral hazard and adverse selection (persistent as well as repeated). In the model an expert whose skills are his private information, faces a finite sequence of tasks, one after the other. Each task's level of difficulty is an...

This article explores a dynamic moral hazard setting in which a principal hires a team of agents for a project. As the project generates revenue upon completion, the principal incentivizes agents' efforts by designing bonuses for success. If bonuses are provided through spot or...

We study an infinitely repeated principal-agent relationship with on-the-job search. On-the-job search is modeled as a dimension of the agent's effort vector that has no effect on output, but raises his future outside option. The agent's incentives to search are increasing in the degree to which...

We investigate the presence of moral hazard and advantageous or adverse selection in a market for supplementary health insurance. For this we specify and estimate dynamic models for health insurance decisions and health care utilization. Estimates of the health care utilization models indicate...

We study contracting between a consumer and an expert. The expert can invest in diagnosis to obtain a noisy signal about whether a low-cost service is sufficient or whether a high-cost treatment is required to solve the consumer's problem. This involves moral hazard because diagnosis effort and...

Would you go to the dentist more often if it were free? Observational data is here used to analyze the impact of full-coverage insurance on dental care utilization using different identification strategies. The challenge of assessing the bite of moral hazard without an experimental study design...

The discussion about health care systems focuses on the dynamics of expenditures and on the weak growth of the revenue base. In this discussion it is widely overseen that medical expenditures and supply of medical services crucially depend on the compensation of physician services. The paper...

The relationship between physician and patient has been discussed intensively in the literature. Nevertheless, they neglect the fact that the production of health not only depends on the medical services supplied by the physician but is also influenced by the patient's compliance. We present a...
