Abstract:
It is hard to evaluate a firm’s R&D performance in a timely manner due to the uncertainties involved in the R&D process. By examining the U.S. listed firms with heavy patenting during 1987-1998, I find that the effects of a firm’s insider trading patterns are significant in explaining the contemporaneous fluctuations in its R&D productivity. This finding is consistent with the hypothesis that management has considerable information about its R&D productivity beyond what is known to outside investors.
