Can Labor-Market Imperfections Explain Changes in the Inverse Farm Size–Productivity Relationship? Longitudinal Evidence from Rural India
利用1982-2008年印度全国农场面板数据，发现农场规模与单位产出反向关系随时间显著减弱，主因是非农劳动力需求推动资本替代劳动，且家庭劳动效率优势在2008年消失。
We use a large national farm panel from India from 1982 to 2008 to show that the inverse relationship between farm size and output per unit of land weakened significantly over time. A key reason was the substitution of capital for labor in response to nonagricultural labor demand. In addition, family labor was more efficient than hired labor in 1982 and 1999, but not in 2008. In line with labor market imperfections as a key factor, separability of labor supply and demand decisions cannot be rejected in the last period, except in villages with very low nonagricultural labor demand. <i></i>
