Abstract

La estimación de distintas especificaciones de funciones de producción agrícola (Cobb-Douglas y de elasticidad de sustitución constante, CES) para el Perú no apoya la hipótesis de la existencia de retornos crecientes a escala. Además, observamos evidencia de la existencia de poder de mercado en el caso del algodón, aun cuando no hallamos el valor del coeficiente que refleja la estructura de ese mercado (oligopsónica o monopsónica). Asimismo, encontramos que la productividad, medida como el residuo de la estimación de dicha función, está positivamente correlacionada con la edad, el sexo, y la educación; y negativamente relacionada con el tamaño de la unidad agropecuaria.
