Whether behavior converges toward rational play or fair play in repeated ultimatum games depends on which player yields first. If responders concede first by accepting low offers, proposers would not need to learn to offer more, and play would converge toward unequal sharing. By the same token,...

In generosity games, one agreement payo is exogenously given,whereas the other is endogenously determined by the proposer's choice of the"pie" size. This has been shown to induce pie choices which are either efficiencyor equality seeking. In our experiment, before playing the generosity...

We study two person-betting games with inconsistent commonly know beliefs, using an experimentalapproach. In our experimental games, participants bet against one another, each bettorchoosing one of two possible outcomes, and payoff odds are know at the time bets are placed.Bettors’ beliefs are...

Unlike previous attempts to implement cooperation in a prisoners’ dilemma gamewith an infinite horizon in the laboratory, we focus on extended prisoners’ dilemmagames in which a second (pure strategy) equilibrium allows for voluntary cooperationin all but the last round. Our four main...

We study interaction effects between intra-firm conflicts and interfirm competitionon a duopolistic market with seller firms employing one or more agents and imple-menting tournament incentives. We show that inter-firm competition leads to higherincentive intensity, higher efforts and output...

Using a symmetric 2-person prisoners’ dilemma as the base game, each playerreceives a signal for the number of rounds to be played with the same partner.The actual number of rounds (the length of the supergame) is determined bythe maximal signal where each player expects the other’s signal...

We report on an experiment designed to explore whether allowing individualsto voice their anger prevents costly punishment. For this sake, weuse an ultimatum minigame and distinguish two treatments: one in whichresponders can only accept or reject the o®er, and the other in which theycan also...

Facing a stochastic market wage, which is independent of their own hiring policy, employersoffer contracts specifying fixed wage, revenue share and employment duration.In ongoing employment relations it depends on the treatment whether fixed wages canbe only increased or also decreased. Will the...

Contrary to the models of deterministic life cycle saving, we take itfor granted that uncertainty of one's future is the essential problem ofsaving decisions. However, unlike the stochastic life cycle models, we capturethis crucial uncertainty by a non-Bayesian scenario-based...

In a public goods experiment, subjects can vary over a period of stochasticlength two contribution levels: one is publicly observable (their cheap talkstated intention), while the other is not seen by the others (their secretintention). When the period suddenly stops, participants are restricted...
