We use the investment game introduced by Berg, Dickhaut and McCabe (1995) to explore gender differences in trust and reciprocity. In doing so we replicate and extend the results first reported by Croson and Buchan (1999). We find that men exhibit greater trust than women do while women show...

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...

The study addresses the issue of sustainability of collusion in one-sided auctions. Earlier experimental studies indicate that, in double oral auctions, collusion is hard to sustain even if conspiracy is allowed and quotation improvement rules are absent. We investigate the role of similar...

We investigate bidder collusion in one-sided ascending price auctions without communication. If bidding rules in an English-type auction allow bidders to match each others' bids, collusion can be sustained as a Nash equilibrium of a one-shot auction game. Our earlier experiments show that in...

Punishing free riders might promote cooperation, but it can also lead to feuds. We use a public good game with punishment opportunities to investigate whether the threat of feuds is e¢ ciency enhancing. Treatments di¤er with respect to whether a punish- ment can trigger a feud. In the main...

We study the relationship between group size and the extent of risk sharing in an insurance game played over a number of periods with random idiosyncratic and aggregate shocks to income in each period. Risk sharing is attained via agents that receive a high endowment in one period making...

Institutions that form to reduce moral hazard often eliminate discretion and pool the actions of heterogeneous agents. An unintended consequence of this pooling is that agents' types cannot be determined by their actions. While in the short run such mechanisms may be optimal, in the long run...
