Past field validity tests of contingent valuation have relied on voluntary contribution mechanisms to elicit actual willingness to pay, and may overestimate hypothetical bias because of free riding in the actual contributions. This paper argues that provision point mechanisms are a preferred alternative for field validity tests of contingent valuation because they increase the proportion of dem...

The extension of contingent valuation models with an attitude-behavior based framework has been proposed in order to improve the descriptive and predictive ability of the models. This study examines the potential of the theory of planned behavior to explain willingness to pay (WTP) in a contingent valuation survey of the recreational benefits of the Zurich city forests. Two aspects of WTP respo...

Contingent valuation (CV) has become one of the most widely used non-market valuation techniques. CV’s prominence is due to its flexibility and ability to estimate total value, including passive use value. Its use and the inclusion of passive use value in benefit-cost analyses and environmental litigation are the subject of a contentious debate. This paper discusses key areas of the debate over...

This paper uses contingent behavior and contingent pricing analyses to explore the proper valuation of time and transport costs within the context of recreation demand. The contingent behavior analysis poses hypothetical increases in access fees, travel time, and travel distance and considers recreation demand responses. As a useful complement, the contingent pricing analysis poses hypothetical...
