| The purpose of this paper is to address a problem that may arise with the assumption of a continuous spatial market in the TCM model. We find that this assumption can be challenged by geographical limitations that an area of study might have. Particularly for islands (or isolated island-like areas) that have a valuable non-market resource or good, the spatial market characteristic of the TCM model might be limited or truncated. The geographical truncation limits the observed maximum travel cost of the demand curve falsely implying a lower WTP than otherwise. The study uses a dichotomous choice CVM to confirm that the resulting demand schedules from the TCM underestimates WTP for day trips to the Caribbean National Forest in Puerto Rico. This results in a... |

| A combined telephone contact-mail booklet-telephone interview of California and New England households regarding their willingness to pay for fire management in California and Oregon's old-growth forests was performed to test hypotheses regarding the spatial extent of the public goods market. Using a multiple-bounded contingent valuation question, the study found that New England households' annual willingness to pay for the California and Oregon programs was statistically different from zero. This analysis points out that households receive benefits from fire protection of old-growth forests in states other than their own. In this case study, limiting the survey sample to state residents where the National Forest is located would reflect about 20% of... |

| Surveys of visitors to National Forests in Colorado were conducted to determine whether different fire ages and presence of crown fires have different effects on hiking and mountain biking recreation visits and benefits. Actual and intended behavior data were combined using a count-data travel cost model. The intended behavior trip questions asked about changes in number of trips due to the presence of a high-intensity crown fire, prescribed fire, and a 20-year-old high-intensity fire at the area respondents were visiting. Using the estimated recreation demand function, years since a non-crown fire had statistically significant positive effect on the trip demand of hikers. In contrast, presence of crown fires had no statistically significant effect on... |

| This research updates the joint estimation of revealed and stated preference data of Cameron (1992) to allow for joint estimation of the Travel Cost Method (TCM) portion using count data models. Further these count data models reflect correction for truncation and endogenous stratification associated with commonly used on-site recreation sampling. Our updated modeling framework also allows for testing of consistency of behavior between revealed and stated preference data rather than imposing it. Our empirical example is river recreation visitors to the Caribbean National Forest in Puerto Rico. For this data set we find consistency between revealed preference and stated preference data. We also find little gain in estimation efficiency in our data. This may... |
