J. Loomis et al., Using the demand for hunting licences to evaluate contingent valuation estimates of willingness to pay, APPL ECON L, 7(7), 2000, pp. 435-438
Taking advantage of differences in inflation adjusted licence prices over t
ime, the demand for hunting licences is estimated. This introduces a differ
ent type of validity test which compares willingness to pay derived from ac
tual licence demand to estimates of hunting benefits derived by the conting
ent valuation method. Willingness to pay estimates for deer and elk hunting
derived from contingent valuation are statistically less than correspondin
g estimates from the actual licence sale demand analysis.
