Agglomerative Forces and Cluster Shapes
Kerr, William R.; Kominers, Scott Duke - Census Bureau, Department of Commerce - 2012
We model spatial clusters of similar firms. Our model highlights how agglomerative forces lead to localized, individual connections among firms, while interaction costs generate a defined distance over which attraction forces operate. Overlapping firm interactions yield agglomeration clusters...

Patent Value and Citations: Creative Destruction or Strategic Disruption?
Abrams, David S.; Akcigit, Ufuk; Popadak, Jillian - Department of Economics, University of Pennsylvania - 2013
Prior work suggests that more valuable patents are cited more and this view has become standard in the empirical innovation literature. Using an NPE-derived dataset with patent-specific revenues we find that the relationship of citations to value in fact forms an inverted-U, with fewer citations...
