We present empirical evidence on diversification patterns in Italian manufacturing firms and detect a robust relationship between firm size and diversification levels, with an elasticity of diversification that does not depend on firm size and is well below unity. Diversification does not lead...

In this work we explore some basic properties of the size distributions of firms and of their growth processes both at aggregate and disaggregate levels. First, we investigate which properties of firm's size distributions and growth dynamics are robust under disaggregation. Second, at a...

This article explores the dynamics of market selection by investigating of the relationships linking productivity, profitability, investment and growth, based on China's manufacturing firm-level dataset over the period 1998-2007. First, we find that productivity variations, rather than relative...

This chapter reviews and integrates much of what has been learned on the processes of technological evolution, their main features, and their effects on the evolution of industries. First, we map and integrate the various pieces of evidence concerning the nature and structure of technological...

This paper presents a broad set of empirical regularities about selection and market shares reallocation in manufacturing industries of France, Germany, UK and USA. We first disentangle the contribution to industry-level productivity growth of within-firm productivity changes and between-firms...

This paper investigates firm-level dynamics of labour productivity in China's manufacturing sector over the 1998-2007. Underlying the aggregate evidence of dramatic growth of labour productivity, one observes a large, even if shrinking, intra-sectoral heterogeneity. A major process of both...
