This paper describes a computer program which has been written to provide maximum likelihood estimates of the parameters of a number of stochastic production and cost functions. The stochastic frontier models considered can accomodate (unbalanced) panel data and assume firm effects that are distributed as truncated normal random variables. The two primary model specifications considered in the program are an error components specification with time-varying efficiencies permitted (Battese and Coelli, 1992), which was estimated by FRONTIER Version 2.0, and a model specification in which the firm effects are directly influenced by a number of variables (Battese and Coelli, 1995). The computer program also 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 efficiency estimates.
