DESCRIPTION:Prof. Ina Gangul\, University of Massachusetts Amherst\n"The P
 aper Trail of Knowledge Flows: Evidence from Patent Interferences"\n\nAbst
 ract\n\nWe show evidence of localized knowledge spillovers using a new dat
 abase of multiple invention from U.S. patent interferences terminated betw
 een 1998 and 2014. Patent interferences resulted when two or more independ
 ent parties simultaneously submitted identical claims of invention to the 
 U.S. Patent Office. Following the idea that inventors of identical inventi
 ons share common knowledge inputs\, interferences provide a new method for
  measuring spillovers of tacit knowledge compared with existing (and noisy
 ) measures such as citation links. Using matched pairs of inventors to con
 trol for other factors contributing to the geography of invention and dist
 ance-based methods\, we find that interfering inventor pairs are 1.4 to 4 
 times more likely to live in the same city or region. These results are no
 t driven exclusively by observed social ties among interfering inventor pa
 irs. Interfering inventors are also more geographically concentrated than 
 inventors who cite the same prior patent. Our results emphasize geographic
  distance as a barrier to tacit knowledge flows.\n
