abstract = {The economics literature clearly shows that the transmission of knowledge diminishes
with physical distance, a factor contributing to industrial clustering. This paper
investigates how those distances have stretched over time. We measure the physical
distance between collaborating inventors, as well as distances between inventors and the
technology cited in their patents. There is an obvious change over time while controlling
for other factors, and we present interesting implications about the distance-dissolving
effects of the communication revolution: firms and independent inventors benefit in
distinctly different ways, while some states and technology classes are obvious winners
over their peers.},
