Hueth, Darrell L.; Strong, Elizabeth J.; Fight, Roger D., tech. eds. Sport fishing: a comparison of three indirect methods for estimating benefits. Res. Pap. PNWRP-395. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station; 1988.99 p. Three market-based methods for estimating values of sport fishing were compared by using a common data base. The three approaches were the travel-cost method, the hedonic travel-cost method, and the household-production method. A theoretical comparison of the resulting values showed that the results were not fully comparable in several ways. The comparison of empirical results showed differences in values not easily accounted for on theoretical grounds. The data base was not designed to provide data for all three methods, and some of the resulting models explain only a small proportion of the variation.
