Abstract

The use of network theory in the input-output field supposes an interesting alternative that allows structural complexity, weakness and strength to be shown. To this end, we analyse the relative position of each industry via core-periphery models to offer an approach to fundamental economy structure. These models are very flexible and can be applied on Boolean or valued graphs. In order to overcome the usual criticisms, we extend previous works and develop core-periphery valued models. This novel proposal is applied to the analysis of the European and Spanish economies in 1995.
