When physicians own complementary medical service facilities such as clinical laboratories and imaging centers, they gain financially by referring patients to these service entities. This situation creates an incentive for the physician to exploit the consumers' trust by recommending more...

We analyze a model of informed trading where an activist shareholder accumulates shares in an anonymous market and then expends costly effort to increase the firm value. We find that equilibrium prices are affected by the position accumulated by the activist, because the level of effort...

Moral hazard and adverse selection create inefficiencies in private health insurance markets and understanding the relative importance of each factor is critical for policy. We use claims data from a large firm to isolate moral hazard from plan selection. Previous studies have attempted to...

This paper examines whether risk-based pricing promotes risk-reducing effort. Such mechanisms are common in private insurance markets, but are rarely incorporated in government assurance programs. We analyze accidental underground fuel tank leaks--a source of environmental damage to water...

It is well known that public or pooled insurance coverage can induce a form of ex-ante moral hazard: people make inefficiently low investments in self-protective activities. This paper points out another ex-ante moral hazard that arises through an induced innovation externality. This alternative...

Real interest rates rose to historically high levels in 1980 and remained high throughout the decade. Macroeconomists attribute this phenomenon to a combination of tight monetary policy, fiscal deficits, and variable inflation rates. This paper presents preliminary evidence for an additional...

There are a large number of cases where corruption has been discovered investigating levels of consumption that appear to be hard to justify. Yet, in the standard moral hazard model withholding of effort by the agent is not observable to the principal. We argue that this assumption has to be...

Hooks and Robinson argue that moral hazard induced by deposit insurance induced banks to invest in riskier assets in Texas during the 1920s. Their regressions suggest this manifestation of moral hazard may explain a portion of the events that occurred during the 1920s, but some other phenomena,...

Eight states established deposit insurance systems between 1908 and 1917. All abandoned the systems between 1921 and 1930. Scholars debate the costs and benefits of these policy experiments. New data drawn from the archives of the Federal Reserve Board of Governors demonstrate that deposit...
