Stochastic frontier production functions have been used extensively to analyze technical
efficiency in the past two decades. The original models of Aigner, Lovell and Schmidt
(1977) and Meeusen and van den Broeck (1977) have been altered and extended in a
numberofways. Onedevelopmenthasbeentoexpressinefficiencyasanexplicitfunction

stochastic frontier is obtained first and the predicted efficiencies are then regressed upon
firm-specific variables. However, a simultaneous estimation procedure has the advantage
of providing consistent and efficient estimates. Battese and Coelli (1993, 1995) proposed
such a model based on panel data.
Having specified the production function, attention is now turned to factors affecting
