Again, the constraint N1' λ = 1 ensures variable returns to scale technology, but removing that constraint allows modeling under the constant returns to scale technology assumption.

In an early study, Bravo-Ureta and Rieger (1991) investigated the effect of farm size on economic, technical and allocative input-oriented efficiency scores of dairy farms in New England. The study used the stochastic frontier analysis to assess the efficiency scores, and the effects of farm size were analyzed with a Kruskal-Wallis test and ANOVA in a second stage. Results showed that farm size, considered in terms of the number of dairy cows, positively affected the technical efficiency, whereas economic and allocative efficiencies were negatively affected.
