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.
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.
