This paper is concerned with the estimation of the binary choice model
without imposing any parametric structure on the distribution of the
stochastic term. We adapt the distribution-free maximum likelihood met
hod developed by Cosslett (1983) for deriving the contingent value fun
ction with respect to observable exogenous variables. We present Monte
Carlo comparisons with the probit estimates and discuss the asymptoti
c consistency and relative efficiency of the approach. Data from a for
est environment valuation survey are used for empirical estimations.
