Where: 



P(Y) = Probability of stating a "yes" response. 



BID = Dollar amount of increased trip cost the hunter was 



asked to pay. 



INCOME = Hunter's household income. 



TRIPS = Number of hunting trips to this area this year. 



DRSEEN = Number of deer seen on this trip. 



HUNTERS = Number of other hunters seen on this trip. 



YRSHNT = Number of years hunter has been hunting deer. 



PURPOSE = Dummy variable indicating hunting as main purpose 



of trip. 

 DRKILL = Dummy variable indicating hunter was successful in 



bagging a deer. 

 CLUB = Dummy variable indicating hunter belongs to a 



conservation organization. 

 AGE = Age of the hunter. 

 In = Natural log of the previously defined variables.

This specification, with perhaps the exception of one or two 

 variables, should be valid for the three improved condition CVM 

 questions as well as for the current trip question. Willingness 

 to pay for improvements on the current trip may not be influenced 

 by the number of other hunters seen or by the dummy variable 

 indicating whether the hunter bagged his/her deer. 



It may be noted that in Equation (1) all independent variables 

 (except dummy variables) are logged. Previous applications have 

 shown that this double-log model generally provides a better fit 

 to dichotomous choice data
