| Abstract: | In this paper, The authors use evidence on the activity of U.S. publicly traded firms from the early 1980s to the mid- 1990s to investigate whether innovation - measured by patenting activity - declines during the mature phase of the industry life cycle. Overall, the analysis reveals that the general level of patenting activity is not lower in mature industries than in emerging industries. The authors also find no evidence of a shift from product to process innovation with industry maturity, and no evidence that leaders innovate less in mature industries than in non-mature industries. The paper also provides a substantial list of references on this subject. |
