Breakthrough Inventions and Migrating Clusters of Innovation

Kerr, William R. - Harvard Business School, Harvard University - 2009

We investigate the speed at which clusters of invention for a technology migrate spatially following breakthrough inventions. We identify breakthrough inventions as the top one percent of US inventions for a technology during 1975-1984 in terms of subsequent citations. Patenting growth is...
