Disposición a pagar por un mejoramiento en la calidad ambiental en el Gran Santiago, Chile

This work presents an estimation of the willingness to pay for projects destined to improve the air quality of the Great Santiago in Chile, through the implementation of a determined number of hectares of green areas. The contingent valuation method is used, assuming a linear function form of the indirect function of utility and a logit distribution. Considering the specific estimation of the willingness to pay, the doubled bound dichotomic choice model gives a value of around 3.8 dollars monthly by family per a year. Extrapolating the willingness to pay by family to all the families of the metropolitan region, and proportionally discounting the people who indicated their rejection to the instrument, it gives an added WTP of US$3.697.990 monthly
