Estimating Technical Efficiency in Major Iranian Manufacturing Sub sectors, (A Panel Data Analysis)

This paper considers the estimation of a technical efficiency model consisting of a Cobb-Douglas Stochastic Frontier Production Function for 6 major Iranian manufacturing sub sectors, using a panel of 70 Iranian sample manufacturing firms for the period 1994-1999. The maximum likelihood method is used to estimate the frontiers and derive the efficiency estimates, which are assumed to be time variant. The evidences suggest that the efficiency of Iranian manufacturing is declining both as a whole and in sub sectors.
