It once took two decades to replace one-third of the Fortune 500; now a subset of new firms are challenging and displacing this elite group at a breathtaking rate, while armies of startups come and go within just a few years. Most new jobs are, in fact, coming from small firms, reversing the trend of a century. David Audretsch takes a close look at the U.S. economy in motion, providing a detailed and systematic investigation of the dynamic process by which industries and firms enter into markets, either grow and survive, or disappear. He shapes a clear understanding of the role that small, entrepreneurial firms play in this evolutionary process and in the asymmetric size distribution of firms in the typical industry.

This collection of essays addresses the vital question of how much the theory of direct foreign investment - developed a decade ago before many drastic changes took place on the international economic scene - still holds. Grouped in five major sections, they cover The Theory of Direct Foreign Investment; Industrial Organization and International Markets; Country Studies; International Finance; and Implications for the United States.

Utilizing a unique data set, Zoltan Acs and David Audretsch provide a rich empirical analysis of the increased importance of small firms in generating technological innovations and their growing contribution to the U.S. economy. They identify the contributions made by both small and large firms to the innovative process and the manner in which market structure, and the firm-size distribution in particular, responds to technological change. The authors' analysis relies on traditional theories of industrial organization and tests existing hypotheses, many of them previously untested due to data constraints. Innovation and Small Firms brings together two large data bases recently released by the U. S. Small Business Administration - one directly measuring innovative activity for large and small firms, the other providing a detailed census of economic activity for all manufacturing firms and plants across a broad spectrum of industries. Acs and Audretsch describe and evaluate the data bases in the context of the literature on innovation, market structure, and firm size. They present their findings on the presence of small firms, small-firm entry in manufacturing, small-firm growth and flexible technology, and mobility and firm size. They compare static and dynamic measures of small-firm viability and address the relationships between R&D, innovation, and productivity, and analyze the interaction between technological regimes and the role of government in innovation.
