Identifying Technology Spillovers and Product Market Rivalry


Mark Schankerman, The London School of Economics and Political Science

The impact of R&D on growth through spillovers has been a major topic of economic research over the last thirty years. A major problem in the literature is that firm performance is affected by two countervailing spillovers: a positive effect from technological knowledge spillovers and negative business stealing effects from product market rivals. We develop a general framework to distinguish these two effects, showing that technology and product market spillovers have testable implications for a range of performance indicators. We exploit these implications empirically with distinct measures of a firm’s position in technology space and product market space. Using panel data on U.S. firms over two decades we show that both technology and product market spillovers operate, but technology spillovers quantitatively dominate. The spillover effects are also present when we analyze three high tech sectors in finer detail and use R&D tax prices as instrumental variables for R&D. Finally, using the model we evaluate the net spillovers from three alternative R&D subsidy policies.
