RESUMEN: El objetivo de este trabajo consiste en analizar el proceso de transmisión de precios a lo largo de la cadena comercial en el sector del tomate en España. Para ello se han considerado el precio percibido por el productor y el pagado por el consumidor. El enfoque metodológico adoptado se basa en la estimación de un Vector de Corrección del Error con umbrales. Los resultados indican que, a largo plazo, los dos precios son homogéneos. Sin embargo, en el corto plazo las reacciones de precios, tanto en velocidad como en magnitud, son asimétricas. Es más, los resultados indican que los detallistas se benefician (en el sentido de que son capaces de aumentar el margen comercial) de cualquier shock, ya sea positivo o negativo, que afecte tanto a las... |

This paper aims to analyse the impact of changes in the monetary policy and the exchange rate on agricultural supply, prices and exports. The methodology used is based on the multivariate cointegration approach. Ten variables are considered: interest and exchange rates, money supply, inflation, agricultural output and input prices, agricultural supply and exports, income and the rate of commercial openness. Sample period covers annual data from 1967 to 2002. Due to the short-sample period, two subsystems are considered. First, long-run relationships are identified in each subsystem. Second, both subsystems are merged in order to calculate the short-run dynamics. Results indicate that changes in macroeconomic variables have an effect on the agricultural... |

The analysis of asymmetries in the price transmission mechanism at different levels of the marketing chain provides some interesting information about the degree of competition in vertical related markets. The objective of this paper is to investigate the non-linear adjustments of prices along the lamb sector in Spain. The methodology used is based on the multivariate approach to specify and estimate a Threshold Autoregressive Model. Price relationships at farm, wholesale and retail levels are considered. Results indicate that in the long-run price transmission is perfect and any supply or demand shocks are fully transmitted to all prices in the system. In the shortrun, analyses suggest that the high degree of horizontal concentration among retailers allow... |

The objective of this paper is to analyse some of the most relevant relationships among macroeconomic variables and the agricultural sector in Tunisia. Three alternative models are specified and estimated: a VAR in levels, an unrestricted Vector Error Correction Model (VECM), and a Restricted VECM in which long-run relationships among the relevant variables are identified. In all models short-run dynamics are analysed through the use of Generalised Impulse Response Functions. Results indicate that alternative model specifications generate different short-run dynamics. Long-run identification seems to be a necessary condition for obtaining consistent economic results. |

This paper has analysed the import demand for virgin olive oil in the EU and more precisely in the Italian market, as it concentrates more than 80% of EU imports, aiming to determine the relative position of Mediterranean EU and non-EU countries exports and their degree of substitutability or complementarity. The methodology used is based on the specification of a Threshold Almost Ideal Demand System in which special attention has been paid to the stochastic properties of the series involved. In an empirical context, the paper has aimed to provide a set of import demand elasticities that can be useful in trade models. Results point to Spain as the leader in the Italian virgin olive oil market. It is expected that this position will be maintained in the... |

Resumen El análisis de las relaciones de precios existentes en un determinado sector permiten, por un lado, ofrecer una idea aproximada del funcionamiento de los mercados y, por otro, anticipar respuestas ante shocks inesperados en mercados relacionados. El objetivo de este estudio se ha centrado en el análisis de la transmisión de precios entre los principales mercados de ovino en España. Para llevar a cabo este estudio se ha adoptado un enfoque econométrico que ha tenido en cuenta las propiedades estocásticas de las series, la posible naturaleza multivariante de los procesos de transmisión, y la distinción entre el comportamiento a corto y largo plazo. Los resultados indican que los mercados de ovino se encuentran bastante interrelacionados pudiéndose... |
