While issues in estimating nonmarket values continue to cause concern, resource economists have more reason now than ever before to be optimistic. More progress toward improved measurement has been made in the past six years than in the previous quarter century since development of the contingent valuation and travel cost methods. The new challenge is to learn how to adjust past studies to estimate nonmarket values for future policy analysis. The process involves developing an understanding of the important variables that explain the observed difference in estimates. This paper illustrates how the results thus far could be adjusted to develop some tentative estimates of the recreation-use value of Forest Service resources. |

The value of sportfishing in the Snake River Basin in Central Idaho was measured using a two-stage/disequilibrium travel model. The two-stage/disequilibrium model does not require monetization of recreationists? travel time as required of traditional equilibrium labor market travel cost models. The model was estimated using Poisson regression, appropriate for count data when over-dispersion is absent, and adjusted for endogenous stratification (self selection bias) . Contrary to expectations that anglers living close to the sites with low values would be over represented in the sample, the endogenous stratification adjustment caused estimated consumers surplus to decline from $42 per person per trip before adjustment for endogenous stratification to $35... |

Demand for outdoor recreation was analyzed at four Lower Snake River reservoirs for the purposes of measuring willingness-to-pay for outdoor recreation trips. Data were collected with a single mailing survey using a list of names and addresses collected from recreationists at the reservoirs during May through October, 1997. The survey resulted in 408 usable responses. Outdoor recreation demand was estimated using a disequilibrium labor market travel cost model that assumed recreationists did not (or could not) give up earnings in exchange for more free time for outdoor recreation. The travel cost demand model related outdoor recreation trips (from home to site) per year by groups of recreationists to the dollar costs of the trip, to the time costs of the... |
