This paper follows a stream of literature on the empirics of sectoral growth rates, originated by Castaldi and Dosi (Income levels and income growth. Some new cross-country evidence and some interpretative puzzles. Our aim is to discuss the statistical properties of growth rates in light of a 'mushroom vision' of growth. In our analysis, we focus on the growth of value added in NACE five-digit sectors in France, Germany, Italy and the United Kingdom between 1995 and 2003. We find that the volatility of sectoral growth rates is negatively correlated with sectoral size, according to a power law, but with steeper slopes than for firms and We wish to thank Giovanni Dosi, Angelo Secchi, Edwin Stuivenwold and Grid Thoma for helpful discussions, and participants of the 11 th International Schumpeter Society Conference in Sophia Antipolis (France) for useful comments. The paper was improved thanks to comments by the editor, Uwe Cantner, and by an anonymous referee. We kindly acknowledge support from the EU funded project DIME.

Rescaled sectoral growth rates are well-described by a Laplace distribution in most years. The outcomes of this statistical analysis provide a further empirical foundation to a view of sectoral growth, wherein interfirm correlations, market concentration, and inter-sectoral feedbacks play a major role.

“…Firms, irrespectively of the levels of disaggregation in terms of production activities, are highly heterogeneous on whatever measure chosen, both on the input and output sides, their efficiencies, degrees of innovativeness, market performances, even in presence of the same input prices (see, within an expanding literature, from Hildenbrand, 1981and Nelson, 1981to Bartelsman and Doms, 2000Dosi and Grazzi, 2006;Dosi, 2007;Dosi and Nelson, 2010;Syverson, 2011). Hence, any "representative agent" hypothesis, in our view, is sufficiently discredited not to deserve serious discussion.…”

Technology and costs in international competitiveness: From countries and sectors to firms

This paper examines the determinants of international competitiveness at the level of sectors and firms. First, we address the relation between cost-related and technological competition in a sample of fifteen OECD countries. Results suggest that the countries' sectoral market shares are indeed mainly shaped by technological factors (proxied by investment intensity and patents) while cost advantages/disadvantages do not seem to play any significant role. Next, we attempt to identify the underlying dynamics at the firm level. We do that for a single country, Italy, using a large panel of Italian firms, over nearly two decades. Results show that also at micro level in most sectors investments and patents correlate positively both with the probability of being an exporter and with the capacity to acquire and to increase export market shares. The evidence on costs is more mixed. A simple measure like total labour compensation is positively correlated with the probability of being an exporter, while unit labour costs show a negative correlation only in some manufacturing sectors.

“…One of the major robust stylised fact emerging from industrial economics is that the firm growth rates distribution is characterised by wide heterogeneity and a tent shape, whatever the level of sectoral aggregation considered (Stanley et al, 1996;Bottazzi and Secchi, 2006;Coad, 2009;Dosi, 2007). In this respect, due to its inherent nature, the processes leading from innovative input to innovative output may show different effects according to the different positioning of a firm in the growth rates distribution, beyond the effect on growth of the "average firm".…”
