Title: Public Information and the Securities Lending with Kevin Smith (Stanford)    

Abstract: We develop a dynamic model to study how the securities lending market affects the trading and pricing of a stock around the arrival of public information. When investors disagree about the firm’s value but agree about how to interpret a public news event given this value, loan fees rise before and fall after the event in proportion to its informativeness. The news reduces the expected stock price after its release when the demand for shorting is high, but has no impact on the pre-announcement price. If little information is expected to arrive, the price can be significantly inflated even when the loan fee is low. When investors disagree more about the news than about firm value, only investors with extreme beliefs take positions before the announcement and the news increases firms’ ex-ante valuations by encouraging trade.

Title: Retail Investors and Corporate Governance: Evidence from Zero-Commission Trading

Abstract: We examine the effects of the sudden abolition of trading commissions by major brokerages in 2019 and subsequent increase in retail-investor base on corporate governance. Firms with greater retail ownership experienced greater positive abnormal returns around the abolition of commissions. Firms with positive abnormal returns in response to the abolition of commissions subsequently saw decreases in institutional ownership, shareholder voting, and corporate governance scores. These firms also reduced the percentage of shares needed for a quorum at shareholder meetings. Our results show that entry costs influence retail ownership and influence on corporate governance.

Title: Incentive Issues in ESG ratings

Abstract: This paper examines incentive issues associated with ESG ratings in a sustainable investment environment with delegated asset management. Within a rational expectations framework, I identify two equilibrium outcomes: one where a rating agency provides unbiased information due to strong investor non-pecuniary preferences, and another where the agency inflates ratings to attract fund investments. The analysis characterizes conditions under which a rating agency may distort scores to cater to fund managers' interests, highlighting potential agency problems that could undermine the reliability of ESG ratings.

Title: When Banks Move Out, What Moves In?

Abstract: We examine how local consumer financial services markets respond to the exit of traditional banks. Using detailed establishment-level data and exogenous branch closures due to mergers, we show that bank exit leads to a decline in the entry of nonbank financial service providers. The reduction is concentrated among businesses offering depository services, such as check cashing outlets, money transfer firms, and ATMs. These results underscore the complementarity between banks and other financial service providers and highlight the broader risks to assess, especially in areas vulnerable to becoming banking deserts.
