Off‐Farm Work Decisions of Farm Couples: Estimating Structural Simultaneous Equations with Ordered Categorical Dependent Variables
估计了农场夫妇的农场和非农劳动供给联立方程，使用有序probit和最小距离估计，发现男性农场劳动每增加1小时会减少1小时非农劳动，但女性没有此替代关系。
Abstract We estimate a full system of structural farm and off‐farm labor supply equations of farm couples as a set of simultaneous equations with categorical dependent variables. In a first step, the reduced form is estimated by ordered probit with unknown thresholds. Then, the identified structural coefficients are recovered from the reduced‐form coefficients through minimum distance estimation. Using census data from Israel, we find that for men, a one‐hour increase in farm labor supply causes a one‐hour decrease in off‐farm labor supply, but not for women. This could not have been found without estimating structural coefficients.
