Robert Evenson and Daniel Johnson ()

Economic Systems Research, 1997, vol. 9, issue 2, 149-160

Abstract: The papers in this issue are directed towards the development of invention input-output (I(IO)) coefficients. They discuss the procedures for creating I(IO) coefficients using the Yale Technology Concordance, which assigns patented inventions to the industry of manufacture and sector of use, utilizing the International Patent Class system. Tests of reliability of the I(Io) coefficients and their use in economic studies are reported.
