R&D: Who does the R, who does the D?

Abstract

This paper examines the determinants of the allocation of national R&D resources between research and development activities. We derive conditions under which a firm being outdistanced by a foreign rival in a two-stage international patent race would drop out, and relate those conditions to home-market size and to the race's cost and risk characteristics. Because of this “discouragement effect”, firms located in smaller markets appear as if they were, on average, less successful in transforming research expertise into commercial product development. We also show that in a two-sector model ( R and D), the proportion of R&D resources going into product development as opposed to research increases with country size. Moreover, starting from a symmetric game and increasing the size of one country induces the opposite effect on other countries (a shift of R&D resources from development to research) through strategic interaction among research teams.
