Abstract
AbstractWhile a number of validity tests exist for contingent valuation data, to date there are very few literature examples for contingent behavior (CB) data. The objective of this study is to test the validity of CB trip data for different levels of rock climbing access using data from surveys implemented before and after a policy restricting recreational access was imposed. Results from generalized Negative Binomial and seemingly unrelated Poisson regression models show significant sensitivity to scope, and suggest that CB data may be a valuable supplement to revealed preference data when policy proposals are outside the range of historical conditions.
