Two Nested Constant‐Elasticity‐of‐Substitution Models of Recreational Participation and Site Choice: An ‘Alternatives’ Model and an ‘Expenditures’ Model
开发了两个休闲参与和地点选择的需求模型，均基于年度效用最大化，允许边际效用递减，且不假设一次旅行目的地独立于其他旅行计划。模型采用嵌套常数替代弹性偏好排序，易于估计，允许地点互补，并应用于大西洋鲑鱼垂钓。
Abstract Two demand models of recreational participation and site choice are developed: an alternatives model and an expenditures model. Both assume maximization of utility over the year, so allow for diminishing marginal utility. They do not impose the restrictive assumption that where one goes on a trip is independent of where one plans to go on other occasions. Estimation is with a nested constant‐elasticity‐of‐substitution preference ordering: it is relatively easy to estimate because of global regularity, it allows sites to be complements, and it has the potential to be locally flexible. The application is to Atlantic salmon fishing.
