Abstract

The robustness of dynamic dual models examined by Howard and Shumway is reevaluated with the proper specification for the modified generalized Leontief (GL) and normalized quadratic (NQ) functional forms. In an application to the Northeastern and U.S. dairy industries, the theoretical properties, adjustment rates, and predictive ability were similar under both functional forms. However, elasticity measures differed significantly.
