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...

This paper focuses on modelling and estimating the starting point bias in closed-ended follow-up questions, where several bids are presented successively, depending on previous answers. Although the contingent valuation literature took off in the last decade, there is only one study modelling...

Through the Water Framework Directive, the European Commission urges its Mem- ber states to reach a level of "good status" of water for 2015. This level can be different from the regional first-best. Neither the supra-regional regulator (European Commission) nor the regional regulator (Member...

Recent surveys report the increasing number of muddy flows in many areas, and point out the fact that agricultural practices (among others) influence significantly the risk and severity of muddy flows. In this paper, we investigate the economic incentives that can be given to the farmer to adopt...

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...

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...

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...
