Joint Recreation Choices and Implied Values of Time

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.
