Using choice experiments to estimate the simulated exchange value of species preservation services for ecosystem accounting
We present a choice experiment for the valuation of preservation services for threatened aquatic wild birds in the coast wetlands of the southwest of the Iberian Peninsula. We test the potential of stated preference methods to estimate non-market exchange values for ecosystem accounting. The experiment was administered to a sample of the adult population of Spain (n = 800) and Portugal (n = 179) in 2019. The program attributes were described as the variation in the number of aquatic wild bird species in each of the three threat categories of the red list of species plus a one-time increase in income taxes for the implementation of the program. The preferred model shows that passive consumers are willing to pay more to reduce a higher number of species in each category, but marginal willingness to pay (WTP) is substantially higher for “critically endangered” species. Based on this model, we estimate a marginal WTP-based simulated exchange value of €440 per person for a one-time payment (equivalent to €16.41 per year for 30 years), which would be paid by 34% of passive consumers. These estimates represent exchange values consistent with the valuation criteria of national accounts in contrast to the Hicksian surplus, which is 1.6 times higher in our application.
