Working Paper Series Valuing Us Marine Habitats: Fantasy or Fact?

چکیده
Data generated by a direct choice experiment with over 1,000 US residents was used to estimate their mean willingness to pay for maintaining or enhancing future use or option value, existence and indirect use values. We term these three values the fantasy value of marine habitats, to mimic what some consider these values to be. Iconic fish taxa were used as proxies to represent coral reef, seamount, estuarine and other marine habitats, so that the mean willingness to pay could be apportioned to the various habitats. Participants were willing to accept a mean increase in the price of fish of between $1.31/pound ($2.88/kg) for salmon to $8.58/pound ($18.88/kg) for shrimp. The resulting total fantasy values for each of the habitats, based on the mean willingness to pay, ranged from $511/km for seamounts to $5695/km for estuaries. These values are of the same order
