The Welfare Impacts of Unanticipated Trip Limitations in Travel Cost Models
研究了旅行成本模型中政策变化导致资源部分关闭时，标准消费者剩余衡量方法可能不适用的问题，并以墨西哥湾红鲷鱼休闲渔业为例说明理论模型选择的重要性。
<i>Travel cost models are routinely used to assess the impact of policy changes on consumer’s surplus. In this paper we show that when the policy change leads to a partial closure of the resource, then the standard use of consumer’ s surplus per trip can be inappropriate depending upon the theoretical behavioral model underlying the analysis. We demonstrate the importance of theoretical model choice using an analysis of the Gulf of Mexico’s recreational red snapper fishery.</i>
