En este artículo se utiliza un modelo de valor actual neto para obtener en forma conjunta la disposición a pagar (DAP) y la tasa de descuento intertemporal por un programa de conservación ambiental de la biodiversidad cuyos períodos de pago se extienden en el tiempo. Se realizan encuestas de valoración contingente para un programa de protección del ecosistema marino de la reserva isla Choros-Damas, y a los encuestados se les preguntó por su DAP con períodos de pago de 1, 5 y 10 años. La tasa de descuento estimada es mayor a la que utilizan las personas en proyectos privados pero significativamente menor a las tasas encontradas en la literatura para proyectos similares.

In this paper we used a net present value model to jointly estimate the willingness to pay (WTP) and the intertemporal discount rate for a biodiversity environmental conservation program whose payments are allocated along a time horizon. We applied a contingent valuation survey to capture the economic value associated with the protection of a marine ecosystem in the marine reserve Choros-Damas in Chile. Respondents faced and scenario with a WTP question with periods of 1,5, and 10 years. The estimated discount rate is larger than the interest rates found in market transactions but significantly lower than rates found in similar environmental projects.
