- Summary: the arrival of COVID-19 case in an area leads to an immediate surge in local anti-Asian animus.

Doctor Who — Can Physicians from Low Socio-Economic Status Families Reduce the Socio-Economic Gradient in Health? (w/ Ida Lykke Kristiansen) SSRN. CEBI Working Paper Series
- Summary: we measure physicians' SES by their childhood SES and find that SES concordance decreases low-SES patients' mortality, while high-SES patients' mortality does not depend on their physicians' background. Together, they translate to a 24% reduction in the SES-mortality gradient. Low-SES patients with low-SES physicians receive more care at the intensive margin, have a higher detection of chronic conditions, and have higher adherence to treatment.
Employer Reputation and the Online Labor Market: Evidence from Glassdoor.com and Dice.com (w/ Ke Ma)
- Draft coming soon
- Summary: we identify the causal impact of Glassdoor ratings using a regression discontinuity framework from both labor demand and supply sides at equilibrium. Displayed employer reputation affects employer’s ability to attract workers, especially when the displayed rating is sticky. Employers respond to the rounding threshold by posting more new positions and re-activating more job postings. The effects are the strongest for firms that are private, smaller, and less established, suggesting that online reputation is a substitute for other types of reputation.
