I am a Ph.D. candidate in the finance area at UCLA Anderson School of Management. My research interests are in corporate finance, governance, and innovation. My job market paper studies the channels through which mature patent-practicing firms make investments in innovation.

I will be available for interviews at the 2017 ASSA meetings in Chicago, Illinois (January 6-8).

Profit Windfalls and Investments in Innovation: Evidence from Patent Term Extensions (Job Market Paper)

Availability: SSRN

I show that mature innovating firms respond to exogenous cash flow by engaging in external patent acquisitions that diversify their patent portfolios into new technologies. By exploiting the random timing of patent term expiry dates and their unexpected extensions due to the Uruguay Round Agreements Act, I find that a one standard deviation increase in the citation-weighted patent portfolio share of term-extended patents leads to an increase in cash flow by 1.5 percent of book assets. Given these windfall profits, I find evidence of physical capital investment, debt issuance reduction, and acquisitions of new external technologies. Internal investments in R&D, on the other hand, show no response, suggesting high R&D adjustment costs for large, mature firms.
