We experimentally investigate how different information about others' individual contributions affects conditional cooperators' willingness to cooperate in a one-shot linear public goods game. We find that when information about individual contributions is provided, contributions are generally...

We propose a simple behavioral model to analyze situations where (1) a group of agents repeatedly plays a public goods game within a network structure and (2) each agent only observes the past behavior of her neighbors, but is affected by the decisions of thewhole group. Themodel assumes that...

We investigate experimentally whether the extent of conditional cooperation in public good games depends on the marginal per capita return (MPCR) to the public good and type of game. The MPCR is varied from 0.2 to 0.4 to 0.8. The "standard" game, in which three players contribute before a...

To examine the effect of group size on the stability of prosocial behavior we used standard one-shot public good experiments with two and four subjects, which were conducted repeatedly three times at intervals of one week. Partner and stranger treatments were employed to control for group...
