WORKING PAPERS
[New] Investor Flows, Monetary Policy, and Portfolio Management of Money Market Funds (with Jay Im and Ashley Wang), updated in January 2024
Summary: How do money market funds (MMFs) manage their portfolios in response to investor flows and monetary policy changes? We find that increased investor flows and anticipation of rate cuts prompt risk-taking, duration-extension, and liquidity-reduction behaviors among MMFs.
Payment Risk and Bank Lending: The Tension between the Monetary and Financing Roles of Deposits (with Ye Li), updated in April 2023
Summary: We model and empirically show that banks' payment risks have a strong negative effect on bank lending and hinder the credit channel of monetary policy transmission. Banks manage such payment risks by setting more attractive deposit rates.

The Network Structure of Money Multiplier (with Ye Li and Huijun Sun), updated in Dec 2022
Summary: Payment network generates liquidity externalities of banks' lending decisions and amplifies the volatility of credit supply. A small set of banks are critically positioned in the network and contribute disproportionately to the credit cycle. .

Carbon Emissions, Mutual Fund Trading, and the Liquidity of Corporate Bonds (with Jie Cao, Xintong Zhan, Weiming Zhang, and Linyu Zhou), updated in Jan 2023
Summary: Mutual funds collectively sell corporate bonds issued by firms with high carbon emissions, driven by funds’ concerns for carbon-related redemption risks, rather than by a permanent shift in funds’ investing preferences. Bonds issued by high-carbon firms experience worse liquidity conditions.

Mutual Fund Fragility, Dealer Liquidity Provisions, and the Pricing of Municipal Bonds (with Maureen O’Hara and Xing (Alex) Zhou), Management Science (2023)
Summary: Could mutual fund fire sales during a major crisis reshape market perceptions and generate lasting effects on asset pricing and dealers' liquidity provision? In the aftermath of the COVID-19 crisis, the pricing of mutual-fund-held municipal bonds reflects a post-crisis "fire sale premium."

Does Mutual Fund Illiquidity Introduce Fragility into Asset Prices? Evidence from the Corporate Bond Market (with Hao Jiang, Zheng Sun, and Ashley Wang), Journal of Financial Economics, 143.1 (2022): 277-302.
Summary: Does liquidity transformation by mutual funds introduce fragility to the underlying market? We create novel bond-level latent fragility measures based on asset illiquidity levels of the bond's mutual funds holders. Bonds with higher such fragility measures experience more volatile returns and outflow-induced selling.

Liquidity Restrictions, Runs, and Central Bank Interventions: Evidence from Money Market Funds (with Lei Li, Marco Macchiavelli, and Xing (Alex) Zhou), Review of Financial Studies, 34.11 (2021): 5402-5437.
Summary: Redemption restrictions on investors, like gates and fees introduced in the 2016 money market fund (MMF) reform, are meant to improve financial stability. However, we find that when such restrictions are contingent on MMF's liquidity level (WLA), it exacerbates the run on MMFs during the COVID-19 crisis.

This paper is cited by the SEC in their Proposed Amendments on Money Market Fund Rules (Dec 2021) to support the proposal of decoupling gates/fees from WLA.
Reciprocal Lending Relationships in Shadow Banking, Journal of Financial Economics, 141.2 (2021): 600-619.
Summary: Post-crisis regulations apply stricter liquidity rules to both money market funds (MMFs) and banks, requiring MMFs to do more overnight lending and banks to borrow longer-term. MMFs and banks resolve this liquidity dilemma by developing a reciprocal “bundling” strategy across various markets.
Institutional Herding and Its Price Impact: Evidence from the Corporate Bond Market (with Fang Cai, Song Han and Dan Li), Journal of Financial Economics, 131.1 (2019): 139-167.
Summary: The level of institutional herding (by insurers, mutual funds, and pension funds) in corporate bonds is substantially higher than what is documented for equities, and sell herding is much stronger than buy herding. In addition, sell herding leads to large price distortions: a return reversal of about 4% in the subsequent 1.5 years. [Additional Appendix]
