Abstract

Este trabajo pretende determinar la interaccion entre mercados pesqueros situados en diferentes niveles de la cadena comercial de la chirla extraida del litoral del Golfo de Cadiz. Se han considerado series de mercados en primera venta-lonjas pesqueras- ya de mercados mayoristas en destino -mercas. la metodologia empleada consiste en la realizacion de contrastes de raices unitarias, contrastes de cointegracion y formulacion de modelos vectoriales de correccion de error disenados para analizar relaciones de causalidad entre los mercadoes considerados. Asimismo, se realizan algunas precisiones acerca del efecto que produce la agregacion temporal en los resultados obtenidos. Para finalizarm se establecen conclusiones averca de la relacion de los resultados obetenidos con las pliticas de gestion de la pesqueria y de orgenacion de mercados puestas en marcha por la Junta de Andalucia, sobre todo en lo relativo a relaciones de causalidad a corto y largo plazo, a la existencia de ciertas distorsiones en la transmision de informacion y a la mejora de la eficiencia de este proceso...This paper analyzes the interaction between fishing markets along the distribution channel of the striped venus coming from the Gulf of Cadiz. Prices concerning ex-vessel and wholesale markets are used. The methodology used is based on unit root tests, cointegration tests, and the formulation of vector error correction models, in order to study causality among prices. In addition, some comments are made about the effects of temporal aggregation on the results. Finally, this study has allowed us to make some conclusions in relation to the management and market planning measures implemented by Junta de Andalucia regarding this fishery. These conclusions mainly deal with short-run and long-run causality relationships, the existence of distortions in the price transmission, and the improvement in the efficiency of this process.
