Contingent behavior (CB) trip data, eliciting intended trip decisions with hypothetical scenarios, has been popular in recreation demand models. Unlike other stated preference methods, the temporal re-liability of CB data has not been examined in recreation demand models, especially in a Kuhn-Tucker (KT) framework. This article as-sesses the temporal reliability of CB trip data collected over three years in KT models. We find that coefficient and welfare estimates are largely reliable over time. Our findings add confidence in using CB trip data to model de-mands within and beyond recreation contexts and provide insight into the broader applica-tion of KT models. (JEL Q26, Q51)
