recreation) resources. When performing natural resource damage 

 assessments the U.S. Department of Interior mandates the use of 

 net willingness to pay in calculation of societal gains and 

 losses (U.S. Department of Interior, 1986). Additionally, the 

 Bureau of Land Management (1982) also uses net willingness to pay 

 in measuring the economic benefits of wildlife when performing 

 cost benefit analysis. Use of net willingness to pay in cost 

 benefit determinations is also recommended in current economic 

 literature (Just, Hueth and Schmitz, 1982; Sassone and Schaffer, 

 1978) .
