Shadow Wages and Peasant Family Labour Supply: An Econometric Application to the Peruvian Sierra
提出一种估计自雇家庭时间分配模型的方法，并应用于秘鲁山区农民家庭劳动供给行为，通过从农业生产函数中估计影子工资，利用工具变量法恢复结构劳动供给参数，结果支持农民家庭理性分配时间。
This paper develops a methodology for estimating structural time-allocation models for self-employed households and applies it to peasant family labour supply behaviour in the Peruvian Sierra. The opportunity costs of time, or shadow wages, of household workers are explicitly estimated from an agricultural production function. Using an instrumental variables procedure, the household's structural labour supply parameters are recovered from variation in these shadow wages. The empirical results are robust to a number of alternative specifications and diagnostic tests and lend support to the rational allocation of time by peasant households.
