Several studies have demonstrated that individual contributions to public goods are increasing in others’ contributions. The underlying causes for this, however, are not yet fully understood. We present a model of duty-orientation in which moral responsibility is learned through observations...

Duty-orientation implies a warm glow of giving as well as a cold shiver of not giving enough. If duty-oriented consumers learn their moral responsibility by observing others’ behavior, social interaction in contribution behavior arises. However, since moral responsibility is a burden,...

Morally motivated individuals behave more cooperatively than predicted by standard theory. Hence,if a firm can attract workers who are strongly motivated by ethical concerns, moral hazard problems like shirking can be reduced. We show that employers may be able to use the firm’s corporate...

In public good games, voluntary contributions tend to start o 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 selfselect into groups committed to charitable...

Hirsch (1976) suggested that as consumption grows, an increasing proportion of the benefits people derive from consumption is due to a status effect. Status is a relative concept that cannot be increased on average; thus it may seem reasonable to expect that as consumption grows, the marginal...

In social dilemmas, there is tension between cooperation that promotes the common good and the pursuit of individual interests. International climate change negotiations provide one example: although abatement costs are borne by individual countries, the benefits are shared globally. We study a...

Are some individuals generally more pro-social than others? If so, socially beneficial commitments could serve as a costly screening device helping the pro-social to match. We present a public good game experiment in which subjects choose between two group types: in blue groups, subjects receive...

There is no consensus on how to measure interpersonally comparable, cardinal utility. Despite of this, people repeatedly make welfare evaluations in their everyday lives. However, people do not always agree on such evaluations, and this is one important reason for political disagreements. Thus,...

“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...
