I see no reason why you should not simply treat your dependent
variable--willingness to pay--as a continuous variable, censored at 0.
That means you can analyze it using a tobit model, or, if you believe
that the process determining the binary decision to be willing to pay
anything (yes or no) is different from the process that determines the
amount, conditional on that amount being positive, then you could
explore a double hurdle type model (see, for instance, Moffatt, Peter
G. 2005. Hurdle models of loan default. Journal of the Operational
Research Society 56 (9): 1063-1071.).
