4. “Noise Trading: An Ad-based Measure” (with Joshua Madsen and Xinyuan Shao)
Motivated by evidence that retail trading spikes on ad days, that firms regularly place ads at weekly intervals, and that weekly ads frequently contain duplicate images, we introduce a measure of noise trading: an indicator of whether the firm placed an ad in the WSJ seven calendar days earlier. Instrumented retail trading is positively associated with informed trading and stock price efficiency.

3. “The Bright Side of Earnings Management” (with Renhui Fu)
Imagine a model that gets into a car accident and is left with an unsightly but temporary scar on her face. It is easy to see that wearing makeup may be a better choice in such a situation because invasive treatment often runs the risk of causing more scars or irreversible side effects. Along this line of thinking, this paper demonstrates the usefulness earnings management as a noise cancelling device. We show that stock underpricing, measured using mutual fund fire sales and the 2003 trading scandal, gives rises to firms' incentives to manipulate earnings but firms cutting R&D underperform those using accruals in the long-run.

2. “The Long-Term Consequences of Short-Term Incentives” (with Alex Edmans and Allen Huang)
This paper shows that short-term stock price concerns induce CEOs to take value-reducing repurchases and M&A. When vesting equity (our proxy for price concerns) increases, stock returns are more positive in the short-term surrounding these events but more negative in the long-term.

1.“Financial Statement Comparability: Theory and Evidence” (with Michael Iselin and Gaoqing Zhang)
We model consistency-based financial statement comparability. We show analytically and empirically that optimal comparability should decrease with both the fundamental correlation and fundamental volatility of economic transactions. Presented at the Yale SOM Fall Accounting Research Conference, 2017; Inaugural Indiana Hoosier Accounting Research Conference, 2017; U Penn - Wharton Spring Accounting Conference, 2017; Minnesota Empirical Accounting Research Conference, 2017
