[This paper demonstrates a positive effect of stock liquidity on blockholder governance. Liquidity increases the likelihood of block formation. Conditional upon acquiring a stake, liquidity reduces the likelihood that the blockholder governs through voice (intervention)—as shown by the lower propensity for active investment (filing Schedule 13D) than passive investment (filing Schedule 13G). The lower frequency of activism does not reflect the abandonment of governance, but governance through the alternative channel of exit (selling one's shares): A 13G filing leads to positive announcement returns and improvements in operating performance, especially in liquid firms. Moreover, taking into account the increase in block formation, liquidity has an unconditional positive effect on voice as well as exit. We use decimalization as an exogenous shock to liquidity to identify causal effects.]

This paper links the CEO's concerns for the current stock price to reductions in real investment. We identify short-term concerns using the amount of stock and options scheduled to vest in a given quarter. Vesting equity is associated with a decline in the growth of research and development and capital expenditure, positive analyst forecast revisions, and positive earnings guidance, within the same quarter. More broadly, by introducing a measure of incentives that is determined by equity grants made several years prior, and thus unlikely driven by current investment opportunities, we provide evidence that CEO contracts affect real decisions.

We aim to tackle the longstanding debate on whether stock liquidity enhances or impedes firm innovation. This topic is of interest because innovation is crucial for firm‐ and national‐level competitiveness and stock liquidity can be altered by financial market regulations. Using a difference‐in‐differences approach that relies on the exogenous variation in liquidity generated by regulatory changes, we find that an increase in liquidity causes a reduction in future innovation. We identify two possible mechanisms through which liquidity impedes innovation: increased exposure to hostile takeovers and higher presence of institutional investors who do not actively gather information or monitor.

This paper studies the market microstructure implications of uninformed trading volume. We capture uninformed volume using spikes in retail trading triggered by weekly advertisements (ads) in the Wall Street Journal that are largely duplicates. We report three findings. First, consistent with a positive volume-volatility relation, stock price volatility amplifies on recurring ad days. Second, informed investors time liquidity to trade more aggressively on recurring ad days. Third, despite the increase in informed trading on such days, price impact is lower, yielding a negative volume–price impact relation. Collectively, the evidence supports the theoretical predictions of Collin-Dufresne and Fos (2016).

Fractional trading (FT)—the ability to trade less than a whole share—removes barriers to high-priced stocks and facilitates entry by capital-constrained retail investors. We observe a surge of tiny trades, measured using off-exchange one-share trades, among high-priced stocks compared to low-priced stocks after FT is introduced to the U.S. equity markets. These tiny trades, when coordinated during attention-grabbing events, are forceful enough to exert large price pressure on high-priced stocks. Further evidence suggests that FT can even fuel meme-stock-like trading frenzies and bubbles in high-priced stocks, for which the feedback effect likely plays a role.

This paper investigates the relation between stock liquidity and firm performance. The study shows that firms with liquid stocks have better performance as measured by the firm market-to-book ratio. This result is robust to the inclusion of industry or firm fixed effects, a control for idiosyncratic risk, a control for endogenous liquidity using two-stage least squares, and the use of alternative measures of liquidity. To identify the causal effect of liquidity on firm performance, we study an exogenous shock to liquidity—the decimalization of stock trading—and show that the increase in liquidity around decimalization improves firm performance. The causes of liquidity's beneficial effect are investigated: Liquidity increases the information content of market prices and of performance-sensitive managerial compensation. Finally, momentum trading, analyst coverage, investor overreaction, and the effect of liquidity on discount rates or expected returns do not appear to drive the results.

This paper provides first evidence of negative peer disclosure (NPD), an emerging corporate strategy to publicize adverse news of industry peers on social media. Consistent with NPDs being implicit positive self-disclosures, disclosing firms experience a two-day abnormal return of 1.6–1.7% over the market and industry. Further exploring the benefits and costs of such disclosures, we find that NPD propensity increases with the degree of product market rivalry and technology proximity and disclosing firms outperform nondisclosing peers in the product markets in the year following NPDs. These results rationalize peer disclosure and extend the scope of the literature beyond self-disclosure.

This paper investigates whether foreign institutional investors affect the global convergence of financial reporting practices. Using several measures of reporting convergence, we show that U.S. institutional ownership is positively associated with subsequent changes in emerging market firms’ accounting comparability to their U.S. industry peers. We identify this association using an instrumental variable approach that exploits exogenous variation in U.S. institutional investment generated by the JGTRRA Act of 2003. Further, we provide evidence of a specific mechanism—the switch to a Big Four audit firm—through which U.S. institutional investors affect reporting convergence. Finally, we show that, for emerging market firms, an increase in comparability to U.S. firms is associated with an improvement in the properties of foreign analysts’ forecasts.

This paper studies the long‐term consequences of actions induced by vesting equity, a measure of short‐term incentives. Vesting equity is positively associated with the probability of a firm repurchasing shares, the amount of shares repurchased, and the probability of the firm announcing a merger and acquisition (M&A). However, it is also associated with more negative long‐term returns over two to three years following repurchases and four years following M&A, as well as future M&A goodwill impairment. These results are inconsistent with CEOs buying underpriced stock or companies to maximize long‐run shareholder value, but consistent with these actions being used to boost the short‐term stock price and thus equity sale proceeds. CEOs sell their own stock shortly after using company money to buy the firm's stock, also inconsistent with repurchases being motivated by undervaluation.
