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.
