Activities in Models of Recreational Demand
构建了一个允许个体同时选择场地属性和活动的模型，纠正了因偏好依赖活动而导致的福利分析偏差，并以哥斯达黎加海滩需求为例验证模型。
<i>Economists have taken divergent approaches to incorporating on-site activities into their empirical specifications of site choice models. We develop a model that explicitly allows individuals to choose both on-site attributes and site activities. This model not only conditions the marginal value of site attributes on the choice of an activity, but also explicitly recovers the marginal rates of substitution across activities. This approach reduces biases in the welfare analysis of changes in site attributes when preferences for attributes depend upon the choice of activities undertaken at the site. We test hypotheses generated by our model by comparing rival models of demand for access to beaches in Costa Rica.</i>
