How do norms of trust and reciprocity arise? We investigate this question by examining behavior in an experiment where subjects play a series of indefinitely repeated trust games. Players are randomly and anonymously matched each period. The parameters of the game are chosen so as to support...

We report on an experiment in which buyers and sellers engage in semi-structured bargaining in two dimensions: how much of a good the seller will produce and how much money the buyer will offer the seller in exchange. Our aim is to evaluate the empirical relevance of two axiomatic bargaining...

The paper presents a simulation of the dynamics of impersonal trust. It shows how a 'trust/reciprocation' norm can emerge and stabilize in populations of conditional cooperators. The norm, or behavioral regularity, is not to be identified with a single strategy. It is instead supported by...

We report on an experiment comparing two institutions governing bargaining over public good allocations. In our setting, two parties bargain over how to allocate a fixed endowment between a public good and two private accounts, one for each party. Parties attach either high or low weight to the...
