The R&D Investment-Uncertainty Relationship : Do Competition and Firm Size Matter?

This paper investigates how competition and firm size affect the relationship between market uncertainty and Ramp;D investment. We use an intuitively appealing measure of firm-specific uncertainty along with panel data to show that firms invest less in current Ramp;D as uncertainty about market returns increases. The effect of firm-specific uncertainty on Ramp;D investment is smaller in concentrated markets - those where market power is higher and strategic rivalry is more intense. Further, the effect of uncertainty on Ramp;D investment is attenuated for large firms which may be the result greater economies of scope
