In this book we study the economic impact of the container traffic at one of the most important port in the Mediterranean: the Port of Algeciras Bay (PAB). In order to meet this general objective we analyse in detail the global framework of the containerisation business and the characteristics that currently condition this process. In a second step the physical characteristics of the PAB in relation to this activity are explained, and the situation in respect of the physical and logistics infrastructrue prevailing in the principal Mediterranean ports is described. In a third step we have carried out an analysis of the evolution of the container traffic, in order to situate the PAB in the contexts of both the Spanish ports and those of the rest of the world. Finally, the economic effects are determined; the economic impacts of the Port of Algeciras Bay and its economic relevance are derived from the application of an economic input-output methodology.
