We attempt to formulate and explain two types of self-fulfilling prophecy, called the Pygmalion effect (if a supervisor thinks her subordinates will succeed, they are more likely to succeed) and the Galatea effect (if a person thinks he will succeed, he is more likely to succeed). To this...

A worker's utility may increase in his own income, but envy can make his utility decline with his employer's income. Such behavior may call for high-powered incentives, so that increased effort by the worker little increases the income of his employer. This paper uses a principalagent model to...

The paper discusses a number of threats to the financial sustainability of social spending: increased internationalization of national economies, gradually higher relative costs of producing a number of human services, the ?graying? of the population, slower productivity growth in the private...

A large literature on ex ante moral hazard in income insurance emphasizes that the individual can affect the probability of an income loss by choice of lifestyle and hence, the degree of risk-taking. The much smaller literature on moral hazard ex post mainly analyzes how a ?moral hazard...

We derive the shape of optimal unemployment insurance (UI) contracts when agents can exert search effort but face different search costs and have private information about their type. We derive a recursive solution of our dynamic adverse selection problem with repeated moral hazard. Conditions...

The issue of whether unemployment benefits should increase or decrease over the unemployment spell is analyzed in a tractable model allowing moral hazard, adverse selection and hidden saving. Analytical results show that when the search productivity of unemployed is constant over the...

The paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure. A new econometric model, the Probit-Poisson-log-normal model with correlated errors, describes the data better than existing count data models. Moreover, it has an...

Consider an employer who wants her employee to work hard. As is well known from the e.ciency wage literature, the employer must pay the (wealth-constrained) employee a positive rent to provide incentives for exerting unobservable e.ort. Alternatively, the employer could make effort observable by...

Recent work in the field of mechanism design has led some researchers to propose institutional changes that would permit parties to enter into nonmodifiable contracts, which is not possible under current contract law. This paper demonstrates that it may well be socially desirable not to enforce...

We analyze innovation race in a moral hazard setting. We develop a model in which two competing entrepreneurs work independently on the same project. The entrepreneurs do not possess any wealth of their own and their research is financed by a venture capitalist. The project, if successful,...
