This paper examines and compares the technical efficiency measures of Ontario and New York dairy producers for the period 1992 to 1998. A nonparametric stochastic frontier model is introduced to estimate technical efficiency. The backfitting algorithm of Breiman and Friedman is used to estimate...

This article uses a nonparametric extension of estimating Generalized Quadratic Box-Cox (GQBC) models using the Additivity and Variance Stabilization (AVAS) algorithm. The new method accounts for random noise in the data and relaxes the sensitivity of technical efficiency scores to the choice of...
