Choice Experiments and Simulated Exchange Values: An Application to Biodiversity for Monetary Ecosystem Accounting 1: Spanish National Research Council (CSIC), Spain; 2: University of Durham, UK; 3: University of Cádiz, Spain We present a choice experiment to estimate the non-market Net Operating Surplus (NOS) of threatened wild species for Monetary Ecosystem Accounting. We use the Simulated Exchange Value (SEV) method, which estimates the maximum amount that could be internalized in a hypothetical market, considering the simulated demand, supply and market structure. The demand is estimated from the choice experiment based on the willingness to pay, additional to the ordinary costs funded with taxes, to avoid an increase in the number of wild species in each threat category of the IUCN Red List. For comparison purposes, we also present equivalent variation estimates. We applied this approach to a survey of the general population of Spain and Portugal for valuing threatened wild bird species in the coastal wetlands of the southwestern Iberian Peninsula. The results show that willingness to pay increases with the number of species reduced in each threat category, with higher significant values for the critically endangered category and no significant differences between vulnerable and endangered species. The NOS estimated using the SEV method offers an annual value of €2,448 per hectare. The equivalent variation is €4,063 per hectare and year. | |
