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,...

When two or more agents compete for a bonus and the agents' productivity in each of several possible occurrences depends stochastically on (constant) effort, the number of times that are checked to assign the bonus affects the level of un-certainty in the selection process. Uncertainty, in turn,...

This paper shows, that after observing the investment decisions by firm owners their employees can engage in costly training, thus increasing their general and firm-specific productivity, which also depends on capital endowment...

We examine the strategic behavior of leaders and followers in sequential duopoly experiments in which followers either perfectly observe the leaders' actions or else observe nothing. (...)

We report on a research program that employs the indirect evolutionary approach to analyze how the institutional environment drives the evolution of trust and trustworthiness through the evolution of moral preferences, and how in turn the evolution of preferences shapes the evolution of the...

In the experiment two bureaucrats independently can grant a permit with the profit of the private party depending on when the permit is given. Whereas one bureaucrat can only veto the project, the second one has additional discretion in granting the permit earlier or later. (...)

In this paper the authors experimentally test overconfidence in investment decisions by ordering participants the possibility to substitute their own for alternative investment choices.

This paper focuses on egocentric biases in financial decisions. Subjects first design a portfolio, whereby each combination of assets yields the same expected return and variance of returns. (...)

In two-person generosity games the proposer's agreement payoffis exogenously given whereas that of the responder is endogenouslydetermined by the proposer's choice of the pie size. Earlier resultsfor two-person generosity games show that participants seem to caremore for eciency than for equity....

One-shot interaction and repeated interaction often co-exist in the real world. We study possible behavioral effects of this co-existence in a principal-agent setting, in which a principal simultaneously employs a permanent and a temporary agent. Our experimental results indicate that there is...
