Patents as quality signals? The implications for financing constraints on R&D

Czarnitzki, Dirk; Hall, Bronwyn H.; Hottenrott, Hanna - 2014

Information about the success of a new technology is usually held asymmetrically between the research and development (R&D)-performing firm and potential lenders and investors. This raises the cost of capital for financing R&D externally, resulting in financing constraints on R&D especially for...

Is Public R&D a Complement or Substitute for Private R&D? A Review of the Econometric Evidence

David, Paul A. - 1999

Is public R&D spending complementary and thus "additional" to private R&D spending, or does it substitute for and tend to "crowd out" private R&D? Conflicting answers are given to this question. We survey the body of available economectric evidence accumulated over the past 35 years. A framework...

Identifying Age, Cohort and Period Effects in Scientific Research Productivity : Discussion and Illustration Using Simulated and Actual Data on French Physicists

Hall, Bronwyn H. - 2005

The identification of age, cohort (vintage), and period (year) effects in a panel of individuals or other units is an old problem in the social sciences, but one that has not been much studied in the context of measuring researcher productivity. In the context of a semi-parametric model of...
