El objetivo principal de este estudio consiste en estimar distintas formas (convencionales y flexibles) funcionales de producción cafetera en Colombia, mediante frontera estocástica. Con los resultados, calcular y analizar las economías a escala por unidad cafetera (productores pequeños, medianos, grandes y sector general cafetero), así como obtener y evaluar la eficiencia técnica de los caficultores asentados en Caldas, Quindío y Risaralda.
This article is an empirical study about flexible and conventional functional forms of coffee production, minflex Laurent Translog function econometrically has been established in Colombia coffee zone for the farm size (smallholders, medium and large farms, general sector), using a stochastic frontier model through standard maximum likelihood method. Likewise, their returns to scale and technical efficiency were derived.
