We analyze the growth of family farms in Israeli cooperative villages between 1981and 1995, using longitudinal data. We use instrumental variables to account for theendogeneity of initial farm size, and correct for selectivity due to farm survival. Wealso include a technical efficiency index, derived from the estimation of a stochasticfrontier production model, as an explanatory variable. We find that technicalefficiency is an important determinant of farm growth, and that not controlling fortechnical efficiency could seriously bias the results. The size distribution of Israelifamily farms is found to be mostly diverging, while without technical efficiency farmgrowth seemed to be predominantly random.
