When environmental quality enters random utility models linearly, welfare measures are convex in quality. The convexity is partly due to site substitution, and it has policy implications for whether changes in quality should be concentrated or diffuse. These functional form effects are...

The manner in which WTP survey responses are elicited has received much attention in the nonmarket valuation literature because of the potential bias that may be introduced via alternate response formats. One issue of particular concern is that of incentive compatibility. Several studies have...
