| Tiivistelmä: | This article proposes a random utility model of recreation demand that addresses the unobserved characteristics of recreation sites. This model avoids the bias unobserved site characteristics can cause in welfare estimates and the travel cost parameter. Monte Carlo simulations motivate the proposed model by showing that it provides more efficient parameter estimates. In contrast, existing methods yield less efficient estimates and biased standard errors that overstate precision. An empirical study of recreationall fishing in Wisconsin describes the potential importance of this modeling innovation. |
