Selection and Recreation Demand
比较了五种使用微观数据估计旅行成本休闲需求模型的方法，重点考察对现场调查中选择效应的不同处理方式，发现选择效应本身影响不大，但估计量的选择会导致每次旅行消费者剩余估计值的较大差异。
Abstract This article compares five methods for estimating travel cost recreation demand models with microdata. The models are distinguished by their treatment of selection effects that arise with on‐site surveys. The comparison considers adjusting for selection effects in a variety of ways, including single and double selection rule models. Both parameter and consumer surplus estimates were evaluated. The findings indicate that the treatment of selection effects alone was not important for this case. However, the choice of an estimator did lead to large variations in per trip consumer surplus estimates.
