Entry in a homogeneous Cournot-oligopoly is excessive if there is business stealing. This prediction assumes that production costs reduce profits and welfare equally. However, this need not be the case. If there is asymmetric information, suppliers or employees can utilize their superior...

We develop a model where a genetic test reveals whether an individual has a low or high probability of developing a disease. A costly prevention effort allows high-risk agents to decrease this probability. Agents are not obliged to take the test, but must disclose its results to insurers, and...

The Enron scandal has raised questions regarding the adequacy of the present system of financial disclosure. At the same time, public policies increasingly use information disclosure as a regulatory device in a variety of areas beyond financial reporting. This paper provides a framework for...

Modern society mitigates and transfers risks in a variety of ways, which range from catastrophe prevention and insurance solutions through to injustices of a minor and inconspicuous nature. We illustrate that the measures taken depend on the uncertainty about the risks in question, and involve...

We develop a stylized principal-agent model with moral hazard and adverse selection to provide a unified framework for understanding some of the most salient features of the recent physician payment reform in Ontario and its impact on physician behavior. These features include: (1) physicians...

This paper evaluates how sick pay mandates operate at the job level in the United States. Using the National Compensation Survey and difference-in-differences models, we estimate their impact on coverage rates, sick leave use, labor costs, and non-mandated fringe benefits. Sick pay mandates...
