Joint Recreation Choices and Implied Values of Time
构建了一个联合休闲数量选择模型，分析人们如何分配远途旅行的时间和次数，从而估算时间的稀缺价值，对研究休闲行为和时间价值的经济学者有参考价值。
A model of joint recreation quantity choices is developed. Individuals choose both total time spent at distant sites and the number of trips taken, implicitly choosing average on-site time. The model permits nonzero marginal utility of travel, makes on-site time endogenous, and is linear in the constraints. The scarcity value of time is analyzed without assuming the marginal utility of work time is zero. A partially testable assumption about relative marginal values of travel and on-site time yields nonparametric calculations of the scarcity value of time and marginal values of trips and days on-site from people's observed optimal quantity choices.
