Update of the Quarterly Model of the Bank of Spain

This paper presents the update of the macroeconometric model used at the Bank of Spain for medium term macroeconomic forecasting, as well as for performing policy simulations. The many changes that the Spanish economy has experimented in the last years, and the new system of national accounts published by the national statistical office, suggested that a re-estimation of the model was due. This paper presents such re-estimation with newer data (up to the end of 2005), and includes some modifications that were deemed necessary in certain equations.The quarterly model of the Bank of Spain keeps a similar structure to its previous version; it still is basically a demand-driven model. It is found that the Spanish economy shows, in general, higher sensitivity than in previous periods to changes in exogenous variables, especially in financial conditions. The new model reflects, too, changes in demographic trends, and presents an external sector less sensitive to changes in price-competitiveness
