Economic Benefits of Sport Fishing and Angler Wildlife Watching in Pennsylvania: A Comment

Upneja et al. (2001) stated correctly that benefit estimates beyond those generated by economic impact analyses are appropriate kinds of information for policymakers and resource managers. The authors’ concern is that Upneja et al.’s article could potentially encourage other travel professionals to estimate travel cost models that provide inaccurate or flawed economic benefit estimates. Problems include using price as the only variable in the demand equation, out-of-pocket travel expenses as a proxy for price, and linear regression instead of a count data process.
