Focuses include power generation, urban and industrial water supply, irrigation, navigation, leisure and recreation-related uses, flood control and water pollution con...

In this paper, we propose a method of determining the opportunity cost of leisure time with an empirical recreation demand application. Typically, the opportunity cost of leisure time is assumed to be some fraction of the wage rate. This practice has limitations. First , it assumes that individuals can trade time for money at their wage. Second, it offers no guidance as to how to value the time...

This study examines time-use for outdoor recreation during 1965 to 2007. Using data on over 47,000 individuals from six nationally representative time-use surveys, we first document time-use trends between 1965 and 2007. We then develop a two-part instrumental variable censored regression model (a hurdle model) to predict individual-level time-use. Our results show that per capita time-use in o...
