Combining revealed and stated preference models for artificial reef siting: A study in the Florida Keys

This paper investigates divers' preferences for artificial reef diving and willingness to pay (WTP) for large ship, artificial reef site attributes in the Florida Keys. We investigate diver demand for existing decommissioned ships that have been sunk off the Florida Keys as well as demand for four new vessels that are available for disposal from the U.S. Department of Transportation Maritime Administration inventory. Using survey data from divers, we compare revealed preference (RP) site choices, stated preference (SP) choices from a discrete choice experiment, and joint RP/SP choices. Our analysis also incorporates stated attribute non-attendance (ANA) at the choice-task level. Our results indicate that the joint RP/SP models with stated ANA are preferred, leading to decreases in marginal WTP as well as decreases in the variability of marginal WTP estimates in the 95% con-fidence intervals. Results provide a framework for directing more efficient future decision making regarding sinkings at locations that will enhance welfare for divers.

Automated summary

This paper investigates divers' preferences for artificial reef diving and their willingness to pay for specific site attributes in the Florida Keys. The study compares revealed preference and stated preference choices among divers, and also considers the presence of attribute non-attendance. The results indicate that the joint RP/SP models with stated attribute non-attendance are preferred, leading to a decrease in marginal WTP and variability of WTP estimates. The findings provide a framework for decision making to enhance welfare for divers.
