VALDIVIA-ALCALA, Ramón et al. Economic valuation for the rehabilitation of the Axtla River, S.L.P.. Rev. Chapingo ser. cienc. for. ambient [online]. 2011, vol.17, n.3, pp.333-342. ISSN 2007-4018.

This paper presents the results of a study to determine the willingness to pay (WTP) for the protection, maintenance and improvement of the Axtla River by the inhabitants of Axtla de Terrazas, San Luis Potosi. For this study, the referendum format contingent valuation method (RCVM) was used. The results were analyzed using logistic regression techniques via maximum likelihood. We conclude that the variables family income, education and pollution damage positively influence WTP, while the bid offered, water quality, number of children who are economically dependent on the household head and age of the household head negatively affect WTP. The study found that residents are broadly receptive to contributing to the rehabilitation of the river, being willing to pay on average 57 pesos per month per household head.

Palavras-chave : referendum format contingent valuation method; willingness to pay; logistic model; maximum likelihood.
