          Abstract

          En México, en la última década cada vez ha sido mayor el uso de contratos en el mercado de futuros para administrar el riesgo en la actividad agrícola. Éste trabajo presenta el cálculo de una cobertura óptima para productores de maíz (Zea Mays L.) en Jalisco en el mercado de futuros utilizando un modelo de media-varianza, éste modelo asume que la función de utilidad está conformada por el ingreso esperado y la varianza del ingreso; se considera que el precio futuro, el precio de contado y el rendimiento representan fuentes de riesgo para el productor. Las medias de éstas variables son estimadas condicionadas a la información pasada de las mismas mediante modelos autoregresivos y de media móvil. En el cálculo se usa también un rango de coeficientes de aversión absoluta al riesgo. Los resultados sugieren que, cuando menor sea la aversión al riesgo la volatilidad del ingreso esperado se incrementa y cuando mayor es la aversión al riesgo el tamaño de la cobertura se estabiliza siendo constante a partir de cierto nivel.

          In Mexico in the last decade has been increasingly greater use of contracts in the futures market to manage risk in agriculture. This paper presents the calculation of optimal coverage for farmers of corn (Zea mays L.) in Jalisco in the futures market using a mean-variance model, this model assumes that the utility function consists of the expected income and variance of income, it is considered that the future price, the spot price and yield represent sources of risk to the producer. The means of these variables are estimated conditional on past information of the same models using autoregressive and moving means. The calculation also uses a range of coefficients of absolute risk aversion. The results suggest that the lower the volatility risk aversion increases the expected income and the higher the risk aversion size remained constant coverage stabilizes at a certain level.
