"Bank of Japan Equity Purchases: The (Non-)Effects of Extreme Quantitative Easing" with Randall Morck and Yupana Wiwattanakantang. (2021). Review of Finance. 25(3):713-743. (Tweetstorm.

Included in CFA Institute's report on ETFs and Systemic Risks.

"Social connections with COVID-19-affected areas increase compliance with mobility restrictions" with Alan Kwan and Vesa Pursiainen. (2020). Science Advances. 6(47):1-10. DOI: 10.1126/sciadv.abc3054. (Data: Facebook Data For Good). NUS Links to the Research Summary: LinkedIn, Twitter, YouTube, Telegram.
A one-standard-deviation increase in social connections with China and Italy - the first countries with major outbreaks of the virus – increases the effectiveness of mobility restrictions by around 50%.
"Does Regulatory Jurisdiction Affect the Quality of Investment-Adviser Regulation?" with Alan Kwan and Tarik Umar. (2019). American Economic Review. 109(10):3681-3712. DOI: 10.1257/aer.20180412. (Official Link. Referred to by a statement by SEC Commissioner Robert Jackson on June 5, 2019.)
Investment advisers switching from SEC to state regulator oversight due to the Dodd-Frank Act had around 30-40% more misconduct.
"Not Coming Home: Trade and Economic Political Uncertainty in American Supply Chain Networks" with Jing Wu and Miaozhe Han. (Media: Sina, Reuters, China Review News Agency, Morningstar, CUHK Blog, The Economist)
Rather than move supply chain networks home, higher U.S. trade policy uncertainty instead predicts more supply chain movements abroad.
Compared to internal forecasts, public forecast appear biased to trade-off between optimism in case of financial constraints versus pessimism to receive higher managerial payoffs.
Debt overhang can have a positive information impact on debt value if secondary markets suffer from information asymmetry.
The effect of common ownership networks in public auctions on bid-rigging appear to increase prices that government agencies pay.
Incorporating the substitution effect from ride-hailing services in taxi demand booking increases taxi allocative efficiency.
Investors chase positive headline stock market index returns on the upside by increasing investment and decreasing consumption but do not respond on the downside.
Firms' investment plans appear important for actual investment and respond to intra-fiscal year firm-level economic conditions, implying existing macroeconomic models with imperfect information overstates the importance of informational frictions.
NPL transactions from banks to local asset management companies end up in the hands of bank borrowers, still exposing them to substantial financial distress risk.
Works in Progress
"Debt in Tiered-Production Networks"
I build a model of network formation to study the impact of network shapes on the distribution of credit risk.
I develop a model to price the value of voting claims embedded in common stock, separate from the cash flow component.
