We focus on the relationship of age and diversification patterns of German machine tool manufacturers in the post war era. Based on trade journals we track the entire firm populations' product portfolio development throughout each firm's lifetime. We distinguish between "minor diversification"...

This work investigates how the export status of the firm influences the patterns of growth at different age classes. We address this research question resorting to a novel set of data that links together the universe of Italian firms and detailed data on export transactions. We find that the...

We examine market selection mechanisms and their strength for a representative cohort of US new independent firms. In particular, we explore whether and how effectively markets reward newly-born firms according to their "fitness" in terms of both labour productivity and profitability. Our...

Recent research suggests that employment in young firms is more negatively impacted during economic downturns than employment in incumbent firms. This questions the effectiveness of policies that promote entrepreneurship to fight crises. We complement prior research that is mostly based on...

This paper illustrates the main features of the Labour Module of the CompNet dataset which provides indicators of firm growth over the period 1995-2012 across 17 EU (13 euro area) countries and 9 macro-sectors. It also includes information on a large set of micro-aggregated characteristics of...

This paper provides evidence that learning about demand is an important driver of firms' dynamics. We present a simple model with Bayesian learning in which firms are uncertain about their idiosyncratic demand parameter in each of the markets they serve, and update their beliefs as noisy...

It is frequently argued that policymakers should target high-tech firms, i.e., firms with high R&D intensity, because such firms are considered more innovative and therefore potential fast-growers. This argument relies on the assumption that the association among high-tech status, innovativeness...

This paper presents a firm and market model that is able to reproduce the empirically observed patterns on firm growth and its statistical characteristics. It goes beyond the existing firm models by reproducing all stylized facts established in the literature. Furthermore, the model is flexible...
