This chapter aims at providing an assessment of the contingent valuation (CV) method. The CV method is a survey-based method used to value environmental goods. The principal idea underlying this method is that people have true, but hidden, preferences for all kinds of environmental goods. It is further assumed that people are capable of transforming these preferences into monetary units (d’Arge, 1985). On the basis of these assumptions, the CV method values environmental goods by simply asking respondents one of the following two questions: What is the maximum amount of money you/your household would be willing-to-pay (WTP) each month/year for obtaining the environmental improvement? What is the minimum amount of money you/your household would be willing-to-accept (WTA) each month/year for accepting the environmental deterioration?1 Both questions are necessary in establishing a hypothetical market for environmental change: a constructed market in which respondents are able to buy (WTP) and sell (WTA) environmental goods.
