A literature in the social sciences proposes that humans can promote cooperation with strangers by signaling their generosity through investment in unrelated pro-social activities. This paper studied this hypothesis by conducting a laboratory experiment with an infinitely repeated prisoner’s...

Based on an experimental analysis of a simple monetary economy we argue that a monetary system is more stable than one would expect from individual rationality. We show that positive reciprocity stabilizes the monetary system, provided every participant considers the feedbacks of his choice to...

The ultimatum heuristic is a decision-making tendency discernible in graphical plots of mixed-motive noncooperative games. As such, it can serve also as a solution approach, backsolving, predicting and explaining outcomes better than the mainstay Nash equilibrium concept whenever data for the...

I experimentally investigate an infinitely repeated market entry game with an informed incumbent firm who knows demand and an uninformed entrant firm who does not. The uninformed firm's profits each period serve as a signal about demand, but the informed firm may signal jam the uninformed firm...

We investigate in a laboratory setting whether revealing information on the intelligence of both players affects behavior in repeated games. We study the Prisoners' Dilemma (PD) and Battle of Sexes (BoS) as they cover a large set of the interesting scenarios generated by repeated games of two...

Team decision-making is often conducted under looming deadlines, where time constraints affect team communication and, consequently, team decisions. This study examines teams' ability to communicate and reach an agreement under time pressure in a coordination game and consequent performance. We...

In dynamic strategic interactions, a player who might be able to spy the opponent’s actions might have incentives to feign ignorance and forgo immediate payoffs, so that he can earn higher future payoffs by manipulating the opponent’s suspicion. I model and experimentally implement this...

This paper contributes to the micro-foundation of money in centralized markets with idiosyncratic uncertainty. It shows existence of stationary monetary equilibria and ensures that there is an optimum quantity of money. The rational solution of our model is compared with actual behavior in a...

Group tasks are often organized by a list: group members state their willingness to contribute by entering their names on a publicly visible, empty list. Alternatively, one could organize the group task by starting with a full list: every group member is already entered on the list and...

For both two person teams and individuals unrestricted communication between opponents in a finitely repeated prisoner dilemma game results in stage-one cooperation rates of between 95-100%. Content analysis of between opponent communication focuses on the increased earnings cooperation can...
