• Welcome!

    I am an assistant professor of economics at the University of Erlangen-Nuremberg. I am also an affiliate member of the CESifo Research Network.

     

    My main fields are labor economics and the economics of innovation.

     

    I obtained my PhD and my undergraduate degree in economics from LMU Munich and a Master's in economics from University College London. During the last years, I have visited the NBER and BU's Questrom School of Business, the MIT Department of Economics, and the Program on Education Policy and Governance at Harvard University.

  • How Antitrust Enforcement Can Spur Innovation

    The innovation impacts of Bell Labs' 1956 consent decree

    How Antitrust Enforcement Can Spur Innovation: Bell Labs and the 1956 Consent Decree

    (with Martin Watzinger, Thomas Fackler, and Monika Schnitzer)

     

    We study the 1956 consent decree against the Bell System to investigate whether patents held by a dominant firm are harmful for innovation and if so, whether compulsory licensing can provide an effective remedy. The consent decree settled an antitrust lawsuit that charged Bell with having foreclosed the market for telecommunications equipment. The terms of the decree allowed Bell to remain a vertically integrated monopolist in the telecommunications industry, but as a remedy, Bell had to license all its existing patents royalty-free. Thus, the path-breaking technologies developed by the Bell Laboratories became freely available to all US companies. We show that in the first five years compulsory licensing increased follow-on innovation building on Bell patents by 17%. This effect is driven mainly by young and small companies. Yet, innovation increased only outside the telecommunications equipment industry. The lack of a positive innovation effect in the telecommunications industry suggests that market foreclosure impedes innovation and that compulsory licensing without structural remedies is ineffective in ending it. The increase of follow-on innovation by small and young companies is in line with the hypothesis that patents held by a dominant firm act as a barrier to entry for start-ups. We show that the removal of this barrier increased long-run U.S. innovation, corroborating historical accounts.

  • Disclosure and Subsequent Innovation

    Does access to patents facilitate regional innovation?

    Disclosure and Subsequent Innovation: Evidence from the Patent Depository Library Program

    (with Jeffrey L. Furman and Martin Watzinger)

     

    How important is access to patent documents for subsequent innovation? We examine the expansion of the USPTO Patent Library system after 1975. Before the Internet, patent libraries provided access to patents. We find that after patent library opening, local patenting increases by 8-20% relative to similar regions, depending on the control group. Additional analyses suggest that disclosure of technical information drives this effect: the effect is strongest in technologies with clear disclosure, inventors increasingly take up ideas from outside their region, and inventor team composition is unaffacted. We thus provide evidence that disclosure plays an important role in cumulative innovation.
