Abstract

El trabajo trata de analizar la relación que existe entre los descensos en los tipos de interés que se han experimentado en España a lo largo de la última década y el estrechamiento en la relación entre el margen financiero y los activos totales medios registrado en las entidades financieras. Para ello, se ha considerado únicamente el grupo de instituciones formado por las Cajas de Ahorros. Debido a las diferencias en tamaño entre ellas, se mostrará que no todas ellas han evidenciado un comportamiento homogéneo respecto a reducciones en los tipos de interés y que esas diferencias pueden explicarse por las características de cada Caja. Por esta razón, se ha procedido a formar grupos homogéneos estadísticamente. Una vez realizada esta división, se plantea un modelo lineal que relacione el impacto de los tipos de interés sobre el ratio formado por el margen de intermediación y los activos totales medios. La estimación se ha realizado utilizando técnicas econométricas de datos de panel. This paper analyzes the relation between the reduction of interest rates and the tightening in the relationship between the financial margin and the average assets in the financial institutions in Spain in the 1990s. To do it, only Cajas de Ahorro have been considered. Due to their different sizes, the behaviour among them is quite heterogeneous and this can be explained using the specific features of each Caja. Cluster analysis is used to identify groups of Cajas based on the homogeneity in behaviour patterns. After classifying in several groups, a linear model between interest rate and the ratio between financial margin and average total asset is estimated using panel data techniques.
