What determines firm growth over the life-cycle? Exploiting unique firm panel data on internal organization, balance sheets and innovation, representative of the entire Canadian economy, we study recent theories that examine life-cycle patterns for firm growth. These theories include organizational capital accumulation and management practices, financial frictions, learning about demand, and recent endogenous growth models with incumbent innovation. We emphasize the importance of differentiating between pure age effects of these theories and effects on size conditional on age. Our stylized facts highlight both empirical successes and shortcomings of current theory. First, models of organizational capital and innovation are broadly consistent with firm size correlations conditional on age but have difficulties matching the life-cycle dynamics of firm organization and innovation. Second, among theories we analyze, organizational capital and management practices are the most important determinants to explain intensive margin firm growth over the life-cycle. Third, although less important to explain intensive margin firm growth, financial frictions are an important determinant of firm exit, conditional on firm age.

This paper examines the variation in life cycle growth across the universe of Mexican firms. We establish two stylized facts to motivate our analysis: first, we show that firm size matters for development by illustrating a close correlation with state-level per capita incomes. Second, we show that few firms grow as much as their U.S. peers while the majority stagnates at less than twice their initial size. To gain insights into the distinguishing characteristics of the two groups, we then econometrically decompose life cycle growth across firms. We find that firms that have financial access and multiple establishments and that are formal, part of diversified industries and located in population centers can grow at sizeable rates.

We use firm dynamics statistics on employment by age, entry, exit, and job flows to identify sources of business cycle fluctuations in the U.S. economy since 1980. We extend the Hopenhayn (1992) firm dynamics model by incorporating capital and debt accumulation to the firm's problem and savings to the consumer's problem. Analyzing the implications of unexpected productivity, credit, labor wedge, and investment wedge shocks for firm dynamics statistics, we show that (a) productivity shock accounts for the 1990-91 and 2001 recessions, and (b) productivity and credit shocks jointly account for the 1980-82 and 2007-09 recessions.

Remarkably, a small fraction of firms account for most of the job and output creation in high-income and developing countries alike. Does this imply that the path to enabling more economic dynamism lies in selectively targeting high-potential firms? Or would pursuing broad-based reforms that minimize distortions be more effective? Inspired by these questions, this book presents new evidence on the incidence, characteristics, and drivers of high-growth firms based on in-depth studies of firm dynamics in Brazil, Côte d’Ivoire, Ethiopia, Hungary, India, Indonesia, Mexico, South Africa, Thailand, Tunisia, and Turkey. Its findings reveal that high-growth firms are not only powerful engines of job and output growth but also create positive spillovers for other businesses along the value chain. At the same time, the book debunks several myths about policies to support firm dynamism that focus on outward characteristics, such as firm size, sector, location, or past performance. Its findings show that most firms struggle to sustain rapid rates of expansion and that the relationship between high growth and productivity is often weak. Consequently, the book calls for a shift toward policies that improve the quality of firm growth by supporting innovation, managerial skills, and firms’ ability to leverage global linkages and agglomeration. To help policy makers structure policies that support firm growth, the book proposes a new ABC framework of growth entrepreneurship: improving Allocative efficiency, encouraging Business-to-business spillovers, and strengthening firm Capabilities. This book is the third volume of the World Bank Productivity Project, which seeks to bring frontier thinking on the measurement and determinants of productivity to global policy makers. 'Policy makers often get carried away by the disproportionate contributions of high-growth firms to job and output growth and commit to pursuing policies targeting the potential ‘stars.’ This book separates fact from fiction underpinning such interventions through a comprehensive analysis of high-growth firms across a range of developing countries, making a compelling argument that public policy to pick prospective winners is neither possible nor desirable. Policy makers would be wise to consult its arguments and policy advice when designing the next generation of policies to support the growth of firms.' William R. Kerr Professor of Business Administration, Harvard University; author of The Gift of Global Talent: How Migration Shapes Business, Economy and Society 'How to ignite and sustain high firm growth has eluded both economic analysis and thought leaders in policy and business. Through its meticulous and thoughtful analysis, this important new book provides a tractable framework to guide policy to harness the growth and productivity potential of firms in the developing-country context.'

Many developed countries are facing a demographic change with an increasing share of older individuals, yet little is known about how older workers will impact regional and national economies in terms of labor market dynamics. This Handbook deals with the important and emerging field of entrepreneurship among this group and focuses on the behavioral perspectives of this phenomenon; on innovation, dynamics and performance; and the ways entrepreneurship among the elderly looks within different countries.
