Estimating the benefits of clean air contingent valuation and hedonic price methods

This study deals with the estimation of willingness to pay for a 50%; reduction of air pollution caused by road traffic in Rabat-Sale (Morocco) using contingent valuation and hedonic price methods. In the CVM, two techniques are employed. These are iterative bidding and dichotomous choice. Both empirical analyses are based on the same set of individuals. This strategy enables us to compare the two techniques; Probit and generalised Tobit models are used for the estimations. Moreover, parametric and non-parametric approaches are used to calculate the mean and median willingness to pay.
