I evaluate the potential usefulness of nonmarket valuation concepts and techniques from environmental economics for improving wildlife conservation. The concepts include distinguishing between on-site recreation use value and off-site passive use or ...

Hanemann's utility difference model for the dichotomous choice contingent valuation method is modified to account for interrelationships between responses to a set of contingent valuation questions. A nonlinear seemingly unrelated regression model is presented to jointly estimate the probit...

This paper empirically tested the three conditions identified by McConnell for equivalence of the linear utility difference model and the valuation function approach to dichotomous choice contingent valuation. Using a contingent valuation survey for deer hunting in California, two of the three...

We review recent likelihood-based approaches to modeling demand for medical care. A semi-nonparametric model along the lines of Cameron and Johansson's Poisson polynomial model, but using a negative binomial baseline model, is introduced. We apply these models, as well a semiparametric Poisson,...

The paper considers the estimation of welfare measures when the functional form of demand is unknown. An adaptation of an argument of Gallant (1987) is used to show that welfare estimators based on a Fourier functional form for demand will be consistent under weak assumptions. Simulation...

Little research has examined the factors influencing differential adoption of organic farming practices by women and men farmers, a sector where women account for a significant and rapidly growing proportion of farmers. Female organic farmers adopt more crop disease management practices than...
