We study how external versus internal innovations promote economic growth through a tractable endogenous growth framework with multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in external R&D to acquire new product lines and in internal R&D to improve their existing product lines. A baseline model derives the theoretical implications of weaker scaling for external R&D versus internal R&D, and the resulting predictions align with observed empirical regularities for innovative firms. Quantifying a generalized model for the recent U.S. economy using matched Census Bureau and patent data, we observe a modest departure for external R&D from perfect scaling frameworks.

This volume uses the study of firm dynamics to investigate the factors preventing faster productivity growth in Latin America and the Caribbean, pushing past the limits of traditional macroeconomic analyses. Each chapter is dedicated to an examination of a different factor affecting firm productivity - innovation, ICT usage, on-the-job-training, firm age, access to credit, and international linkages - highlighting the differences in firm characteristics, behaviors, and strategies. By showcasing this remarkable heterogeneity, this collection challenges regional policymakers to look beyond one-size-fits-all solutions and create balanced policy mixes tailored to distinct firm needs.

An authoritative look at the microeconomics of entrepreneurship Entrepreneurs are widely recognized for the vital contributions they make to economic growth and general welfare, yet until fairly recently entrepreneurship was not considered worthy of serious economic study. Today, progress has been made to integrate entrepreneurship into macroeconomics, but until now the entrepreneur has been almost completely excluded from microeconomics and standard theoretical models of the firm. The Microtheory of Innovative Entrepreneurship provides the framework for introducing entrepreneurship into mainstream microtheory and incorporating the activities of entrepreneurs, inventors, and managers into standard models of the firm. William Baumol distinguishes between the innovative entrepreneur, who comes up with new ideas and puts them into practice, and the replicative entrepreneur, which can be anyone who launches a new business venture, regardless of whether similar ventures already exist. Baumol puts forward a quasi-formal theoretical analysis of the innovative entrepreneur's influential role in economic life. In doing so, he opens the way to bringing innovative entrepreneurship into the accepted body of mainstream microeconomics, and offers valuable insights that can be used to design more effective policies. The Microtheory of Innovative Entrepreneurship lays the foundation for a new kind of microtheory that reflects the innovative entrepreneur's importance to economic growth and prosperity.

Zoltan Acs explores the relationship between industrial innovation and economic growth at regional level and reaches conclusions as to why some regions grow and others decline. The book focuses on innovation and the growth of cities by the use of endogenous growth theory.

Susan Cozzens, Dhanaraj Thakur, and the other co-authors ask how the benefits and costs of emerging technologies are distributed amongst different countries _ some rich and some poor. Examining the case studies of five technologies across eight countri

This book presents the current state-of-the-art in all major and upcoming areas of entrepreneurship research. Thousands of scholars around the world are currently working to broaden our understanding of the entrepreneurial phenomenon. The disciplines involved are numerous, as are the topics of interest, with substantial efforts to enhance the existing knowledge. This book is specifically designed to facilitate high-level, high-intensity discussions and fruitful exchanges between scholars involved in entrepreneurship research. The articles address a variety of topics ranging from self-employment, technology, growth patterns and job creation, and success and failure rates, to historical, conceptual and comparative international approaches. “This book takes entrepreneurship beyond the individual, size of the venture, entrepreneurial personality, and looks at entrepreneurship as a long term complex process that is heterogeneous, content dependent with an emphasis on innovation and growth. A must read for individuals interested in entrepreneurship, today and in the future, on a domestic and global basis.” – Robert D. Hisrich, Director – Walker Center and Garvin Professor of Global Entrepreneurship, Thunderbird School of Global Management “Entrepreneurship is perhaps not just the most multifaceted but also the most important concept of the modern socio-economic disciplines. This book makes an invaluable contribution in this fascinating area: it presents a multifaceted socio-economic examination of the impact of entrepreneurship for growth.” – Roy Thurik, Erasmus School of Economics in Rotterdam and Montpellier Business School

This paper examines the role of intellectual property and other innovation incentives in the development of one field of breakthrough innovation: nanotechnology. Because nanotechnology is an enabling technology across a wide range of fields, the nanotechnology innovation ecosystem appears to be a microcosm of the global innovation ecosystem. Part I describes the nature of nanotechnology and its economic contribution, Part II explores the nanotechnology innovation ecosystem, and Part III focuses on the role of IP systems in the development of nanotechnology.
