Cout prive de morbidite due a la pollution de l’air a Cotonou

Air pollution is an externality whose health costs are high. In our paper we have evaluated the private cost or cost of suffering due to morbidity associated with this pollution. The contingent valuation method (CVM) has allowed us to estimate the average monthly private cost of illness for a head of household on the basis of willingness to pay (WTP) of household heads for a halving of pollution air in the city of Cotonou. The analysis of WTP using a censored Tobit model with consideration of the endogeneity of the variable "income" has allowed us to derive the average WTP that represents the private cost whose value is estimated at 1.617 FCFA / month per adult.
