                             ABSTRACT
           This paper considers a new stochastic frontier production function which
        permits the marginal production risks of inputs to be negative or positive
        and the technical efficiency of firms to be a function of the levels of the
        factor inputs.
           Previous frontier production function models, which have specified
        either zero or positive marginal risks, do not permit sufficient flexibility
        for many empirical applications. The proposed frontier model incorporates
        the production risk structure, suggested by Just and Pope (1978), and the
        stochastic frontier production function model, proposed by Aigner, Lovell and
        Schmidt (1977) and Meeusen and van den Broeck (1977).                          ~
           Maxlmum-llkellhood estimation of the parameters of the frontier
        production function and the prediction of technical efflciencies of firms are
        considered, given that cross-sectional data on sample firms are available.
