About me

I am a postdoctoral researcher at the DFG Research Training Group 2720 “Digital Platform Ecosystems (DPE)”, University of Passau. My research interests are in applied microeconomic theory, especially industrial organisation, on the topics of innovation and competition.


Works in progress

We examine the effect of the proposal to introduce essentiality checks for declared standard-essential patents on incentives to innovate.

This paper presents a model of multiple innovators, whose resulting inventions may be (imperfect) complements or substitutes, and derive the value-sharing rules that maximise the expected social value of innovation. Under this framework, the paper examines an influential policy in the context of standard setting, that royalties for standard-essential patents should reflect the outcome of a hypothetical competition prior to standard setting, and shows that in the presence of both potential complements and substitutes, the competitive outcome provides suboptimal incentives for innovation.
