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...

We investigate experimentally whether higher trust leads to increased performance by relying on simple trust games. Our results show that trust and performance are positively related but not as strongly as suggested in the investment game. As a side result, we observe that the rewards of the...

This paper reviews the different methods that have been used for measuring health costs. Since the cost of illness method captures only the "social cost" (medical expenses and loss of income), we recommend that it be used in conjunction with contingent valuation because the latter yields the...

[paper in French] Recent surveys report the increasing number of muddy flows and point out the fact that agricultural practices (among others) play an important role in their occurrence. We propose to use an ambient tax/subsidy instrument to induce farmers to adopt better practices. The...

[eng] Health benefits induced by environmental quality: are private costs negligible?. . For a complete estimation of morbidity effects associated with environmental damages, the paper pleads in favour of the use of two methods: the cost of illness method (COI) and the contingent valuation...

The purpose of this paper is to analyze the implication of wetland construction for the cost-effective design of a pesticide charge. A model is developed in order to show that, for a given target, the introduction of wetland construction can reduce overall abatement costs and can lower the input...

Individual preferences must be evaluated to take into account the citizens' interests for public decisions. Usually, economists assess individual preferences through market decisions. But more often, public decisions impact goods without market prices. Without a market to refer to, evaluating...

Through the Water Framework Directive, the European Commission urges its Member 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...
