Testing the Validity of Contingent Behavior Trip Responses
利用攀岩政策实施前后的调查数据，检验条件行为出行数据在不同攀岩准入水平下的有效性，发现其对政策范围变化敏感，可作为揭示偏好数据的补充。
Abstract While 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.
