How Racial Animus Forms and Spreads: Evidence from the Coronavirus Pandemic (w/ Yanying Sheng)SSRN. arXiv.

Accepted at JEBO

  • Current version: Oct 2021

  • Presented at AEA, APPAM*, SOLE^.

  • Featured in CEPR Covid Econ papers, Vox TalksSouth China Morning PostWeekendavisen

  • Summary: we show that the arrival of COVID-19 case in an area leads to an immediate surge in local anti-Asian Google searches and Twitter posts. Moreover, public figures' opinions on the issue matters -- online animosity and offline hate incidents against Asians both heighten when President Trump more frequently links China and COVID-19 in his tweets.

Social Undermining as a Dark Side of Symbolic Awards: Evidence from a RD Design (w/ Teng Li)SSRN.
2nd round R&R at OBHDP

  • Current version: Mar 2022

  • Presented at SOLE, COPE, ACLEC poster, EMCON, Warwick PhD conference

  • Summary: This paper studies the effects of a non-pecuniary symbolic award on winners, losers, and their peers, using a RD design. We find that barely winners perform worse than barely losers after the award designation, and peer sabotage is the main culprit.

Partisan Entrepreneurship (w/ Joey Engelberg, Jorge Guzman, Will Mullins). SSRN

  • Current version: Apr 2022

  • Awarded Colorado Finance Summit Best Paper, MFA Best Corporate Finance Paper

  • Presented at NBER Entrepreneurship SI*, HEC Paris Entrepreneurship Workshop*, Colorado Finance Summit*, SoCal PE, MFA, LMU, EFA

  • Summary: we show that Republicans start more firms than Democrats, and that this difference is time-varying: Republicans increase their relative entrepreneurship during Republican administrations and decrease it during Democratic administrations (and vice versa).

Stale Information in the Spotlight: The Effects of Attention Shocks on Equity Markets (w/ Siyu Chen). SSRN.

  • Current version: Jan 2022

  • Awarded SWFA Best Doctoral Paper in Financial Markets

  • Presented at SWFA, AFA poster, FMA PhD Session, ABFE, SFA, IBEFA

  • Summary: Using a RD design, we study the causal impact of an influential star analyst award on market reaction and analysts’ post-award performance. Award announcement leads to higher market reaction to stocks with preexisting recommendations from barely winners than those from barely nonwinners. Evidence strongly suggests that attention trading and speculative trading are the main driving force.
