摘要

我们提出了一种新的方法，通过使用同一专利的不同地点的共同发明人在申请后和授权前的死亡，来估计和隔离由于一个人的实际存在而导致的知识溢出的本地化。该方法估计了已故发明家和在世发明家在当地引用的差异，范围越来越远。与在世的共同发明者相比，在死者周围20英里范围内，专利被引用的次数要少26%。差异随着时间和距离而减弱，当仍然活着的共同发明者住得离死者更远时，差异就更大，并且对于可能过早死亡的子样本来说，这种差异是成立的。(j31, j33, j34, r32)

Isolating Personal Knowledge Spillovers: Coinventor Deaths and Spatial Citation Differentials

We propose a new method to estimate and isolate the localization of knowledge spillovers due to the physical presence of a person, using after-application but pre-grant deaths of differently located coinventors of the same patent. The approach estimates the differences in local citations between the deceased and still-living inventors at increasingly distant radii. Patents receive 26 percent fewer citations from within a radius of 20 miles around the deceased, relative to still-living coinventors. Differences attenuate with time and distance, are stronger when still-living coinventors live farther from the deceased, and hold for a subsample of possibly premature deaths.
