Computing returns to scale under alternative models

This paper provides a comparison of returns to scale when computed with a non-parametric (linear programming) and a parametric (linear programming) method. The two models are applied to a data set for the Japanese agricultural sector and the comparison shows that scale characteristics obtained are m...
