Output growth decomposition of the Greek olive-oil sector under technical and allocative inefficiencies, economies of scale and technical change, is performed. The stochastic production frontier model is extended to panel data and FGLS estimation. Conventional inputs are main source of growth:...

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...
