We conduct a laboratory experiment to study how, after a history of decay, cooperation in a repeated voluntary contribution game can be revived in an enduring way. Simply starting the repeated game over - a simple fresh start - leads to an initial increase of cooperation, but to a subsequent new...

We conduct a laboratory experiment to study how advice affects the gender gap in the entry into a real-effort tournament. Our experiment is motivated by the concerns raised by approaching the gender gap through affirmative action. Advice is given by subjects who have already had some experience...

This paper examines the relation between adjustment patterns and equilibrium selection in laboratory experiments with two types of simple signaling games. One type of game has two Nash equilibria, of which only one is sequential. The other type has two sequential equilibria, only one of them...

Bertrand competition under decreasing returns involves a wide interval of pure strategy Nash equilibrium prices. We first present results of experiments in which two, three and four identical firms repeatedly interact in this environment. More firms lead to lower average prices. However, prices...

We study experimentally how the ability to communicate affects the frequency andeffectiveness of flexible and inflexible contracts in a bilateral trade context where sellers canadjust trade quality after observing a post-contractual cost shock and a discretionary buyertransfer. In the absence of...

This paper presents evidence that the willingness to punish an unfair action is sensitive to whether this action was preceded by a deceptive message. One player first sends a message indicating an intended play, which is either favorable or unfavorable to the other player in the game. After the...

We study whether behavior in experimental gift-exchange markets with repeated interaction is affected by market conditions. One issue we consider is the impact of competitive imbalance, by varying whether there is an excess supply of firms or an excess supply of workers in the market. Workers...
