The Supply of Off‐Farm Labor: A Random Coefficients Approach
构建了农场主和配偶非农劳动决策的联合模型，使用两阶段固定和随机系数方法估计供给函数参数，发现参数具有随机性，且配偶决策对供给函数结构有重要影响。
Abstract A joint model of off‐farm labor decisions for farm operator and spouse is presented. Attention is given to operator and spouse participation decisions as well as associated problems of multiple sample selectivity biases. Two‐stage fixed and random coefficient methods, corrected for possible selectivity biases, are used to estimate supply function parameters. Results indicate that supply function parameters are random. Variation in important supply parameters is investigated. Results also illustrate the importance of spouse decisions on off‐farm labor supply function structure.
