Escobal, J. y Paz Cafferata, J. (1990). Opciones de política de precios agrícolas en el Perú: el caso de las bandas de precios (Documento de trabajo N° 8). Lima: GRADE.

This paper analyses, based on the Peruvian experience, the main motivations for state intervention in the agricultural price formation process. It also postulates a price band mechanism to reduce price variability by linking the medium- and long-term evolution of prices to the opportunity costs of agricultural goods.
