A COMPUTER-PROGRAM FOR FRONTIER PRODUCTION FUNCTION ESTIMATION FRONTIER VERSION 2.0

The computer program FRONTIER will provide maximum-likelihood estimates for parameters of a number of stochastic frontier production function models. The most general model formulation considered is that set out in Battese and Coelli (1992), in which firm effects are assumed to be the product of an exponential function of time and a non-negative random variable having truncated normal distribution. The model considers panel data which need not be complete. The computer program permits the estimation of many other models which have appeared in the literature through the imposition of simple restrictions. Asymptotic estimates of standard errors are calculated along with individual and mean estimates of technical efficiency.
