Funciones de producción, análisis de economías a escala y eficiencia técnica en el eje cafetero colombiano: una aproximación con frontera estocástica

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
