If individual abilities are imperfectly observable, statistical discrimination may affect hiring decisions. In our lab experiment, pairs of subjects solve simple mathematical problems. Subjects then hire others to perform similar tasks. Before choosing whom to hire, they receive information...

Individuals with a preference for keeping moral obligations may dislike learning that voluntary contributions are socially valuable: Such information can trigger unpleasant feelings of cognitive dissonance. I show that if initial beliefs about the social value of contributions are sufficiently...

Although physicians are often expected to be gatekeepers to health insurance benefits such as paid sick leave, research indicates a substantial reluctance to reject patient requests for sickness certificates. We show that private information on the patient's part creates a conflict between the...

Voluntary contributions to public goods have been shown to increase when contribution behaviors become observable by peers. We examine the effect of social pressure on moral behaviour, using a framework distinguishing explicitly between observable and nonobservable forms of contribution. We show...

While people often avoid learning about negative social consequences of their actions in order to behave selfishly, many social situations involve another person who is in a position to impose this information. How does the presence of a potential informer affect information, behavior, and...

In public good games, voluntary contributions tend to start off high and decline as the game is repeated. If high contributors are matched, however, contributions tend to stay high. We propose a formalization predicting that high contributors will self-select into groups committed to charitable...

"Green" consumers appear to accept individual responsibility for public good provision. The propensity to take such responsibility may depend on beliefs about others' behavior, even for consumers motivated by internalized moral norms, not by social sanctions. This can produce multiple...

Work contributes to people's self-image in important ways. We propose a model in which individuals have a preference for being important to others. This leads to the following predictions: 1) In fully competitive markets with performance pay, behavior coincides with the standard model (bakers)....
