Location for Random Utility Models From Uncertainty in Self-Reported Spatial Data: Determining the Value of Coral Reefs

Greater awareness of the importance of ecosystem services and ecosystem management has sparked
interest in examining on-the-water location choices of fishermen; however, some studies still rely on selfreporting
due to high costs or governmental restrictions to obtaining GPS and satellite information. Selfreported
data may be inaccurate due to spatial comprehension difficulties or an unwillingness to truthfully
report on-the-water locations. Uncertainty in spatial data can lead to significant differences in the
outcomes of valuation studies since travel cost estimates are highly dependent upon location
specifications. This study examines the implications of uncertainty in self-reported data on willingness to
pay estimates obtained from random utility models using self-reported data from recreational anglers in
Puerto Rico. Inability to translate on-the-water locations to grid cells on a map and concerns about area
closures may have adversely impacted the quality of data obtained from these fishermen. This study
examines the effects of locational uncertainty on the estimated value of coral reefs around Puerto Rico.
