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...

In the experimental scenario several agents repeatedly invest in n (n = 2) state-speciïfic assets. The evolutionarily stable and equilibrium (Blume and Easley, 1992) portfolio for this situation requires to distribute funds according to the constant probabilities of the various states. The...

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

We present an experimental test of a shirking model where monitoring intensity is endogenous and effort a continuous variable. Wage level, monitoring intensity and consequently the desired enforceable effort level are jointly determined by the maximization problem of the firm. As a result,...

We analyse an experimental public goods game in which group members can endogenously determine whether they want to supplement a standard voluntary contribution mechanism with the possibility of rewarding or punishing other group members. We find a large and positive effect of endogenous...

Direct transfers allow heirs to freely use what has been passed on to them. Bequeathers who do not trust their descendants to make proper use of the fortune may prefer investing it in a safe foundation, thereby limiting their descendants’ autonomy. In our study we compare experimentally these...

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...

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. (...)
