Abstract: This paper reconciles two recent trends: declining international research collaboration and rising return migration of researchers. Using patent data, I show that when Chinese institutions hire returnee inventors, international collaboration falls in the returnee's technology fields, while domestic patenting rises. This reduction in collaboration is accompanied by a drop in cross-border knowledge flow, measured by foreign patent citations, with no decline in domestic citations, and is concentrated in fields with strong prior international ties. Extending the analysis to the institutional group with multiple establishments, I find that after a returnee joins, collaboration-oriented establishments experience an even greater fall in international collaboration than the hiring establishment. These effects persist after controlling for policy changes and hiring strategy, and indicate that returnees substitute for international collaboration, shift innovation toward domestic teams, and reduce outward knowledge flow at both the establishment and group level.

The financial objective of Corporate Venture Capitalists: Evidence from the UK’s Corporate Venturing Scheme

Presented at WEFI Student-led Workshop 2022 and LSE PhD workshop

[Draft on request]

Abstract: I study whether expected financial returns affect corporate venture capitalists' investment decisions using a novel dataset of UK corporate venture capital investments identified through administrative data. Leveraging the termination of the UK Corporate Venturing Scheme, a corporate tax relief program, as well as eligibility requirements based on the size of the investor, the exogenous financial incentive attracts less experienced corporate investors who allocate lower total investments and engage in shorter investment periods. I further demonstrate that ventures invested in by financially motivated CVCs exhibit a lower rate of trade sale and IPO exit, a reduced probability of dissolution within five years, but they do not show a lower post-investment asset growth rate.
