ON REGIONAL SHOCKS IN THE SPANISH ECONOMY

It is well known that the nature of potential shocks impinging on a set of countries or regions may have important implications for relevant aspects of economic policy. This paper addresses the shocks issue empirically by applying the State Space methodology and the Kalman Filter to the case of the Spanish regions. The main conclusions are as follows: (i) it seems that the shocks affecting the Spanish regions have been mostly symmetric; (ii) their effects have been persistent rather than transitory; and (iii) supply shocks have been slightly more frequent than demand shocks.
