Deciding how to allocate forage among animals is a fundamentally important process in range management. The wisdom of these decisions can be enhanced by estimating the marginal value of forage needed by competing species. We present a method for ...

The paper is concerned with developing a production theory for the case when some inputs have nonlinear prices because the price depends on endogenous quality. This involves extending the notion of a cost function to the case where nonlinear prices are ...

This paper extends the standard travel cost method (TCM) to develop estimates of the economic value of recreational chinook salmon fishing on the Gulkana River, Alaska, under existing and hypothetical fishery management conditions. Respondents were asked ...

Conclusions concerning trends in natural resource scarcity may depend critically on the choice of scarcity index. Unfortunately, the prevalence of vertical integration in natural resource industries has hindered the use of some otherwise desirable ...

This paper reviews research on nonmarket valuation. It seeks to gauge whether the methods are up to the tasks demanded of them and to identify new research priorities. The evaluation suggests that we can outline a protocol for implementing and using the methods with some resources, while for...

This paper argues that the belief that discrete contingent valuation (CV) questions yield substantially larger estimates of the mean (and the median) willingness to pay (WTP) for nonmarket resources in comparison to open-ended CV questions is unfounded. Monte Carlo experiments estimate the...

This paper reports the first test evaluating whether stated choices as part of a contingent valuation survey discriminate between significant and trivial causes. Using a random digit dialed sample for North Carolina, two different plans were posed to respondents-one to expand a popular North...
