We use the voluntary contribution mechanism to investigate whether smaller action sets lead to higher cooperation rates. We find that this is the case for groups of four players.

This paper investigates the relationship between relative earnings and giving in a twostage, real-effort experiment. In the first stage, four players compete in a tournament that determines their earnings. In the second stage, they decide whether they wish to transfer part of their earnings to...

Evidence shows that real-effort investments can affect bilateral bargaining outcomes. This paper investigates whether similar investments can inhibit equilibrium convergence of experimental markets. In one treatment, sellers’ relative effort affects the allocation of production costs, but a...

In the first stage, four players compete in a tournament that determines their earnings. In the second stage, they decide whether to make a transfer to one or more of their group...

In the public goods literature, there have been recently a number of experiments which demonstrate how the problem of the under-provision of a public good can be solved through mutual monitoring and sanctioning between the members of a group when antisocial behavior is observed. In many...

A number of studies have shown that peer punishment can sustain cooperation in public good games. This paper shows that the format used to give subjects feedback is critical for the e¢ cacy of punishment. Providing subjects with infor- mation about the earnings of their peers leads to lower...
