In this set of research projects, I use different measurements of patenting outcomes to examine how patent enforcement impacts invention and innovation activities as well as innovation disclosure. One empirically examines the impact of patent enforcement by different types of entities, including Patent Assertion Entities, on invention in patent technology classes using difference-in-difference models. Another explores how patent enforcement impacts firms’ innovation disclosure and IP differentiation in the technology space using natural language processing.
My research interests include economics of innovation, information disclosure, intellectual property rights, and digitization. My research develops novel methods to measure innovation, explores the fundamental forces that drive firms’ decisions on public disclosure of innovation activities, and investigates how patent right enforcement impacts innovation disclosure.
In this set of research projects, I use textual analysis to measure innovation, examine the economic importance of innovation, and explore the application of textual analysis in innovation and management research.
