Temporal Reliability of Contingent Behavior Trip Data in Kuhn-Tucker Recreation Demand Models
研究了在库恩-塔克休闲需求模型中，连续三年收集的条件行为出行数据在系数和福利估计上的时间可靠性，发现结果基本可靠，为这类数据的应用提供了支持。
<h3>Abstract</h3> 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 reliability of CB data has not been examined in recreation demand models, especially in a Kuhn-Tucker (KT) framework. This paper assesses 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 demands within and beyond recreation contexts and provide insight into the broader application of KT models.
