Lach, Saul and Schankerman, Mark (1987) The interaction between capital investment and r&d in science-based firms. 2377. National Bureau of Economic Research, Cambridge, MA., USA.
This paper analyzes the interaction among R&D, capital investment , and the stock market rate of return for 191 firms in science-based industries for the period 1973-1981. Using a framework based on dynamic factor analysis, we show how several prominent hypotheses about the determination of R&D and investment generate testable parameter restrictions. The data indicate that R&D Granger-causes investment, but that investment does not Granger-cause R&D. We use this finding to examine the validity of those hypotheses, to characterize the movements over time of R&D and investment, and to measure the stock market valuation of these movements.
