We consider the interaction of intrinsic motivation and concerns for social approval in a laboratory experiment. We elicit a proxy for Fairtrade preferences before the experiment. In the experiment, we elicit willingness to pay for conventional and Fairtrade chocolate. Treatments vary whether...

In empirical analyses of games, preferences and beliefs are typically treated as independent. However, if beliefs and preferences interact, this may have implications for the interpretation of observed behavior. Our sequential social dilemma experiment allows us to separate different interaction...

Optimal voting rules have to be adjusted to the underlying distribution of preferences. However, in practice there usually is no social planner who can perform this task. This paper shows that the introduction of a stage at which agents may themselves choose voting rules according to which they...

We present simple one-shot distribution experiments comparing the relative im-portanceof efficiency, maximin preferences and inequality aversion, as well asthe relative performance of the fairness theories by Bolton and Ockenfels (2000)and Fehr and Schmidt (1999). While the Fehr and Schmidt...

We present a theoretical and empirical analysis of stable coexistence among the world's anchor currencies (G3): the dollar, euro and yen. The theoretical model presented in this paper builds on a model of spatial competition and rests on a set of assumptions related to the behavior of central...

We present an experiment to compare the two fairness theories by Bolton and Ockenfels [ERC] and by Fehr and Schmidt [F&S]. If one wants to compare their predictive power, most of the experiments that are interpreted retrospectively are not helpful, since both theories make equal or very similar...

Simulations indicated that, in the class of 2 x 2 games which only have a mixed equilibrium, payoffs are increased by risk aversion compared to risk neutrality. In this paper I show that the total expected payoff to a player over this class in equilibrium is indeed higher if this player is risk...
