The Value of Wetlands in Quebec: a Comparaison between Contingent Valuation and Choice Experiment

This study aims to evaluate the non-market values of ecosystem services generated by wetlands in Southern Quebec. To accomplish this, we evaluated the value of wetland services related to 1) habitat for biodiversity, 2) flood control, 3) water quality and 4) climate regulation. Two non-market valuation methods are proposed, contingent valuation (CV) and choice experiment (CE). Our study aims to...

Construct Validity of Dichotomous and Polychotomous Choice Contingent Valuation Questions* Running Head: Validity of DC and PC Contingent Valuation

In this note we conduct construct validity tests for dichotomous choice (DC) and polychotomous choice (PC) contingent valuation questions. Contrary to previous results, we find that DC and PC estimates of willingness to pay are theoretically valid, convergent valid, and similar in terms of statistical precision. Similar to previous results, PC respondents are less sensitive to information than ...

Contingent Valuation and Incentives

We Ž nd statistical evidence of more afŽ rmative responses in the referendum treatment relative to the individual contribution treatment, some weak s...
