Estimates of technical and scale inefficiencies of tobacco farms in Greece during the period 1991-1995 are obtained by using the parametric approach. The degree of technical efficiency was found to be lower than the degree of scale efficiency and thus a greater portion of overall inefficiency is...

Due to the assumption that the best practice methods refer to each input separately instead of the whole set of inputs used by a firm, the benchmark technology as defined in the stochastic varying coefficient frontier model may be infeasible and theoretically improper whenever the maximum...

This article attempts to integrate the production- and the efficiency-based approaches for evaluating the impact of extension on farms' performance. For this purpose the nonneutral production frontier model is used, and the empirical analysis refers to a sample of farms from Crete, Greece. The...
