Carrasco, M and Felipe Vásquez Lavín. 2014. “Estimación conjunta de la disposición a pagar y de la tasa de descuento inter-temporal para la protección de la biodiversidad en la reserva marina de Choros-Damas.” Cuadernos de Economía 33:63: 589-611.
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 a 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.
