  text: <jats:p> 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. (JEL O31, O33, O34, R32) </jats:p>
