Innovation, Firm Size, and R&D Search

Abstract

We present evidence that small firms perform two to four times more innovations per dollar of R&D than large firms. We propose a search theory of R&D that accounts for the evidence. A firm incurs R&D expenses until it has discovered a level of R&D productivity that is sufficiently great to warrant stopping the search. We show that because the large number of R&D projects run by a large firm becomes a substitute for enhanced R&D productivity, the average R&D productivity of a firm is decreasing in firm size.
