In this paper, the authors offer a nonparametric method of decomposing the Fisher ideal index of productivity into individual factors measuring technical efficiency change, allocative efficiency change, shift in the cost function, scale economies due to output change, and an adjustment factor...

Using the non parametric approach of Data Envelopment Analysis (DEA) this paper examines the input and output efficiencies of the Indian pharmaceutical firms for the period 1991 to 2005.

This paper provides a necessary and sufficient condition for the equivalence of three alternative measures of the elasticity of factor substitution: the Allen-Uzawa partial elasticity; the shadow elasticity; and the general two-factor, two-price elasticity.

This paper develops a generalized profit function that incorporates price distortions resulting from imperfect market conditions, sociopolitical and institutional constraints, as well as technical and allocative inefficiency. The model is applied to test (1) the appropriateness of the...

This study is primarily concerned with investigating the technical, allocative, and scale inefficiency of owner-operators of dairy farms in Utah. A stochastic production frontier has been applied to analyze these inefficiencies. The results indicate that there is positive association between...
