This article reports the results of a simple bargaining experiment on the ultimatum-revenge game. The game enables to differentiate between fairness that is stimulated by intentional based motives, distributional motives, and fairness considerations that mix both motives. The laboratory...

This article tests experimentally whether a high degree of collusion on advertisement expenditures facilitate tacit price collusion in duopoly markets. Two environments are tested, in which the size of the spillover between advertising expenditures is varied. The results show that the...

Transparency and accountability are often regarded as crucial for good governance and the efficient organization of public affairs. To systematically explore the impact of transparency and accountability on cooperation, we conduct a series of laboratory experiments on a variation of the public...

We experimentally show that current models of reciprocity are in- complete in a systematic way using a new variant of the ultimatum game that provides second-movers with a marginal-cost-free punish- ment option. For a substantial proportion of the population, the de- gree of rst-mover unkindness...

This paper experimentally investigates the nature of impulses in impulse learning. Particularly, we analyze whether positive feedback (i.e., yielding a superior payo in a game) or negative feedback (i.e., yielding an inferior payo in a game) leads to a systematic change in the individual...

This paper explores potential endowment effects of contractual default rules. For this purpose, we analyze the Hadley liability default clause in a model of bilateral bargaining of lotteries against safe options. The liability default clause determines the right for the safe payoff option. We...
