Be productive or face decline. On the sources and determinants of output growth in Italian manufacturing firms

We investigate the sources and determinants of output growth of Italian manufacturing firms. Applying stochastic frontier techniques, we decompose output growth into factor accumulation and TFP growth from 1998 to 2003. TFP growth is further decomposed into technological change, efficiency change, and scale effects.We find that both input accumulation and TFP growth are important in explaining output growth. In addition, efficiency change (technological catch-up) is the most significant component of TFP growth. Finally, using a specific formulation of the asymmetric error component, we find that R&D spillovers, banking efficiency and public infrastructures have statistically significant and economically relevant effects on the technological catch-up.
