I am an assistant professor of economics at the University of Erlangen-Nuremberg. I am also an affiliate member of the CESifo Research Network (Labor Economics) and an associate member of the LASER Research Network at the University of Erlangen-Nuremberg.
My main fields are labor/education 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.
Disclosure and Subsequent Innovation
Does access to patents facilitate regional innovation?
Disclosure and Subsequent Innovation: Evidence from the Patent Depository Library Program
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.

Peer Mentoring and Online Teaching Effectiveness
Do peer mentors improve online education outcomes?
Can Peer Mentoring Improve Online Teaching Effectiveness? An RCT During the COVID-19 Pandemic
Online delivery of higher education has taken center stage but is fraught with issues of student self-organization. We conducted an RCT to study the effects of remote peer mentoring at a German university that switched to online teaching due to the COVID-19 pandemic. Mentors and mentees met one-on-one online and discussed topics like self-organization and study techniques. We find positive impacts on motivation, studying behavior, and exam registrations. The intervention did not shift earned credits on average, but we demonstrate strong positive effects on the most able students. In contrast to prior research, effects were more pronounced for male students.

The Impact of ICT on Innovation
Did access to BITNET promote innovation?
ICT, Collaboration, and Science-Based Innovation: Evidence from BITNET
Does access to information and communication technologies (ICT) increase innovation? We examine this question by exploiting the staggered adoption of BITNET across U.S. universities in the 1980s. BITNET, an early version of the Internet, enabled e-mail-based knowledge exchange and collaboration among academics. After the adoption of BITNET, university-connected inventors increase patenting substantially. The effects are driven by collaborative patents by new inventor teams. The patents induced by ICT are exclusively science-related and stem from fields where knowledge can be codified easily. In contrast, we neither find an effect on patents not building on science nor on inventors unconnected to universities.

Patents on General Purpose Technologies
Are the blocking effects of patents different for GPTs?
Patents on General Purpose Technologies: Evidence from the Diffusion of the Transistor
What is the role of patents in the diffusion of General Purpose Technologies? In defense of antitrust lawsuits, Bell started licensing one of the most important technologies of our time, the transistor. In this paper, we identify the effect of this licensing on follow-on innovation. Facilitated licensing increased innovation and market entry in particular by young and small companies in unconcentrated markets. In contrast to patents on other technologies, patents on General Purpose Technologies block substantial cross-technology follow-on innovation.
