"Clusters of Entrepreneurship and Innovation," in Josh Lerner and Scott Stern, editors, "Innovation Policy and the Economy, Volume 14" University of Chicago Press (2014) M3 - presented at "Innovation Policy and the Economy 2013", April 23, 2013 AB - This paper reviews recent academic work on the spatial concentration of entrepreneurship and innovation in the United States. We discuss rationales for the agglomeration of these activities and the economic consequences of clusters. We identify and discuss policies that are being pursued in the United States to encourage local entrepreneurship and innovation. While arguments exist for and against policy support of entrepreneurial clusters, our understanding of what works and how it works is quite limited. The best path forward involves extensive experimentation and careful evaluation. ER -
