Abstract

We analyze sector specific shocks in productivity and demand in 19 manufacturing sectors of the Austrian economy. Based on a structural vector autoregressive (SVAR) model with long run restrictions developed by Gali's (1999) we extract technology and non-technology shocks from sectoral andaggregate data and study their patterns and relationship by means of a principal components analysis. We find a close association of sectoral and macroeconomic non-technology shocks but only a very weak association for technology shocks. Impulse-response analysis indicates that for almost all manufacturing sectors and the Austrian economy productivity growth rates experience an immediate increase to positive technology shocks while the hours worked decline. We therefore confirm Gali's results on the level of manufacturing industries. Finally, we use the identified shocks as explanatory variables in fixed effect regressions on growth rates of employment, output and investment. We find that our shocks are closely associated to employment growth and output growth but not to growth in investment. The effect of technology shocks is different on the level of manufacturing industries and the aggregate economy.
