Measurements are obtained from the estimation of a stochastic multi-output input distance function. This study corrects for sample selection bias in the context of a translog functional form that appears when some farms produce only two outputs. The empirical results indicate that diversification economies are found to exist in the efficient small farms. However, greater diversification lead to lower technical efficiency.
