Recreation Demand Analysis under Truncation, Overdispersion, and Endogenous Stratification: An Application to Gros Morne National Park

Using on-site survey data from Gros Morne National Park in Newfoundland, this paper estimates and compares several truncated count data models of recreation demand. The model that not only accounts for the truncated and overdispersed nature of the data but also for endogenous stratification duet o the oversampling of avid users, while allowing for flexible specification of the overdispersion parameter dominates on the basis of goodness of fit. The results are used to estimate the users’ value of access to the park.
