The purpose of this paper is to derive a common set of parameters which underlie the functions determining the probability that a farm operator works off the farm (at the zero off-farm work days position), this days of work, off-farm daily wage, and his asking wage. Two functions are derived. The first describes the behavior of the off-farm daily wage faced by the operator. The second function determines the value of the asking wage, which is the value the farm operator places on his time.
