We show that the preference to act as a leader rather than as a follower is related to subjects’ behavioral type. We rely on the methodology proposed by Fischbacher et al. (2001) and Fischbacher and Gächter (2010) in order to identify subjects’ behavioral types. We then link the likelihood...

In Keser and Willinger (IJIO, 2000) we found that many contracts offered by experimental subjects do not satisfy incentive compatibility. While the combination of incentive compatibility and a binding participation constraint would require that the agent incurs a net loss in the less favorable...

In this paper, we show that expressed willingness-to-pay (WTP) for reducing symptoms caused by air pollution, crucially depends on the respondents being aware of the origin of the symptoms. We observe that the average stated WTP is 50 % higher when respondents are informed in the questionnaire...

In this paper, we investigate an audit policy that allows a regulator to control past declarations of an agent who is caught to fraud in the current period or to adopt an action that is not desirable for Society. Coupled with redistribution effects due to the production of a public good, we show...

We designed an experiment on voluntary contribution to a public good with interior solution. The treatment variable is the equilibrium level of contribution. We observe that the verage overcontribution rate (cooperation) is affected by the equilibrium level of contribution. Overcontribution is...

We study experimentally the outcome of a 50 periods repetition of a two-player coordination game, which admits two-pure strategy Nash equilibria that are Pareto-ranked: a payoff-dominant equilibrium and a risk-dominant equilibrium. The experiment consists of a 2x3 factorial design, with two...

We show that experimental subjects tend to contribute more to the public good if they perceive the actions of the others as a source of positive externality rather than a source of negative externality. In our experiment partial contribution to the public good is the unique subgame perfect...

In nonpoint source pollution problems, the regulator does not observe each polluter’s individual emission, which prevents him from using the conventional policy instruments. Therefore new instruments have been designed to regulate this type of pollution. In an experiment, we compare the...

Overcontribution in experiments on voluntary contribution to a public good has not yet received a fully satisfactory explanation. In those experiments, subjects cooperate, in contradiction with the game-theoretic prediction. In contrast, in oligopoly-experiments and common pool resource...
