Tourists' preferences and willingness to pay for protecting a World Heritage site from coastal erosion in Vietnam

Literature shows that tourists can make significant financial contributions towards efforts of erosion prevention, but very few studies are done in the context of developing countries, especially to protect World Heritage sites. This paper provides the first estimates of willingness to pay (WTP) for differing coastal erosion measures by domestic and foreign tourists visiting Hoi An, an UNESCO World Heritage site located in Vietnam. Using a discrete choice experiment, our study presents several new and important findings. Tourists support visible protection structures and trees on beaches even though these hard measures can affect the natural aesthetics. There exists preference heterogeneity among tourists. Most importantly, our analysis shows that WTP of each tourist is USD $13.45, nearly seven times greater than WTP by local residents estimated in previous literature for a similar erosion protection program.
