PERDOMO, JORGE ANDRÉS  and  HUETH, DARRELL LEE. Estimation of the Production Functional Form, Returns to Scale and Technical Efficiency in Colombian Coffee Zone by Means Stochastic Frontier. Rev.Colomb.Estad. [online]. 2011, vol.34, n.2, pp.377-402. ISSN 0120-1751.

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.

Keywords : Elasticity; Functional form; Maximum likelihood estimation; Production function; Stochastic regression.
