| RESUMEN: La diferencia temporal existente entre la planificación de la oferta y la demanda de productos agrarios, conlleva a que, tradicionalmente, en sectores como el de frutas y hortalizas cobren gran interés las teorías sobre formación de expectativas de precios. En las últimas décadas, la tendencia hacia una mayor interrelación entre la producción y la comercialización (en origen) presente en entidades asociativas implica un aumento de la disponibilidad y utilización de la información para realizar previsiones sobre las distintas variables. El objeto de este estudio es determinar empíricamente la existencia de estimaciones sobre el precio, tomando como referencia actividad productora-comercializadora del sector hortofrutícola del sureste español, que... |

| The present study advocates a simulation approach to analyze quantitatively the impact of having locally-based markets for price derivatives. A major result is that market outcomes do not appear to be sensitive to most of the underlying parameters of the model other than demand elasticity and transportation costs. For the case of inelastic demand, introduction of a futures market in a country provides domestic producers with a competitive edge if transportation costs. The most important insight of the present analysis is that, under realistic scenarios it need not be the case that local producers will gain a competitive edge over foreign producers by introducing a futures market based on the local spot prices. |

| This paper examines supply response models in a rational expectations framework for each one of the four major Greek meat markets, i.e. beef, broiler, lamb and pork. A multivariate GARCH model with Cholesky decomposition is used to incorporate price volatility into the rational expectations supply response model for each meat category and as a result the conditional covariance matrix remains positive definite without imposing any restrictions on the parameters. The empirical results confirm the existence of rational behaviour by meat producers in the four examined markets and indicate that price volatility is a major risk factor in Greek meat production while feed prices and veterinarian medicine prices are both important cost factors. Furthermore, the... |
