Recreational values of coral reefs at Cu Lao Cham islands, Vietnam

Abstract

This thesis used the travel cost approach to estimate the recreational values of coral reefs at Cham islands, Vietnam. Since the on-site data has addressed some problems such as non-negative integers, zero-truncated, endogenously stratified and overdispersion, two count models: the Poisson model and negative binomial model have been used in the study. From the econometric results, we can clearly see that the negative binomial models produced better results than the corresponding Poisson models. It is also indicated that the gross Consumer surplus of total visitors to Cham islands in 2013 is about VND 292.75 billion and the gross WTP of total visitors is about VND 7.12 billion.
