Uncovering GPTS with Patent Data

Hall, Bronwyn H; Trajtenberg, Manuel - National Bureau of Economic Research (NBER) - 2004

This paper asks the question: Can we see evidence of General Purpose Technologies in patent data? Using data on three million US patents granted between 1967 and 1999, and their citations received between 1975 and 2002, we construct a number of measures of GPTs, including generality, number of...

Patents as Quality Signals? The Implications for Financing Constraints on R&D

Hall, Bronwyn H; Czarnitzki, Dirk; Hottenrott, Hanna - National Bureau of Economic Research (NBER) - 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...

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

Hall, Bronwyn H; MAIRESSE, Jacques; Turner, Laure - National Bureau of Economic Research (NBER) - 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...

Market Value and Patent Citations: A First Look

Hall, Bronwyn H; Jaffe, Adam; Trajtenberg, Manuel - National Bureau of Economic Research (NBER) - 2000

As patent data become more available in machine-readable form, an increasing number of researchers have begun to use measures based on patents and their citations as indicators of technological output and information flow. This paper explores the economic meaning of these citation-based patent...

Proprietary vs. Public Domain Licensing of Software and Research Products

Hall, Bronwyn H; Gambardella, Alfonso - National Bureau of Economic Research (NBER) - 2005

We study the production of knowledge when many researchers or inventors are involved, in a setting where tensions can arise between individual public and private contributions. We first show that without some kind of coordination, production of the public knowledge good (science or research...
