Abstract

This paper aims at disentangling the sectoral and aggregate affects of both aggregate and sector-specific shocks by means of static and dynamic factor analytical models. We use two data sets, Gross Value Added and the industrial Production Index, and the results differ slightly. For the Industrial Production Index sectoral shocks have greater sectoral effects than aggregate shocks in the short run, however in the longer run aggregate shocks have a more permanent effect on the leve1 of economic activity. On the other hand, aggregate shocks explain a greater variability of the sectoral Gross Value Added data. In both cases the aggregate effect of sectoral shocks is, however, fairly small. Este trabajo trata de determinar que proporción de la varianza de diversas series de actividad económica es debida a factores específicamente sectoriales y que proporción puede ser atribuida a un componente agregado, a partir de datos sectoriales de Valor Añadido Bruto (VAB) e Indice de Producción Industrial (IPI) y modelos factoriales dinámicos de factor común no observable. Los resultados difieren ligeramente según utilicemos los datos de VAB o del IPI. Así para el Indice de Producción Industrial los efectos sectoriales de los shocks sectoriales suelen dominar a los efectos sectoriales de los shocks agregados en el corto plazo, mientras que a a largo plazo los shocks agregados muestran un efecto más permanente sobre el nivel de actividad económica.Por su parte, para los datos de Valor Añadido Bruto los shocks agregados explican una mayor variabilidad en la actividad económica sect orial en la mayoría de sect ores, most rando así una mayor importancia. Para ambos grupos de series el efecto agregado de los shocks sectoriales es, sin embargo, reducido.
