Using Internet search volume of dividend-related keywords to measure investor preference for dividends that varies over time and across states, we show that dividend sentiment affects corporate policies and asset prices. Investors search more for dividends when economic conditions are poor, with the peak volume reached during the recent COVID-19 pandemic. Firms initiate or increase dividends when dividend sentiment is stronger, especially in regions with strong dividend sentiment. Shifts in dividend sentiment predict higher investor demand for dividends and higher returns for high dividend stocks. Further, mutual funds that pay high dividends receive more inflows when dividend sentiment is stronger.

We examine the relationship between shareholder leverage constraints and corporate risk-taking, focusing on its impact on debtholders. Our findings show that mutual fund leverage constraints are related to more risk-taking activities of portfolio companies, inducing higher credit risk and greater risk-shifting concerns for the firms’ debtholders. In response, the debtholders raise borrowing costs and tighten lending conditions. These effects intensify for firms facing higher levels of conflict between debtholders and shareholders and when mutual funds exert greater influence over firms. Econometric analyses, including instrumental variable specifications and asset management company mergers, support a causal interpretation.

Investors' individual arbitrage models introduce idiosyncratic risk into complex asset strategies, driving up average returns and Sharpe ratios. However, despite the attractive risk‐return trade‐off, participation is limited. This is because effective Sharpe ratios in complex asset markets vary with investors' expertise. Investors with higher expertise, better models, and lower resulting idiosyncratic risk exposures realize higher Sharpe ratios. Their demand deters entry by less sophisticated investors. As predicted by our model, market dislocations are characterized by an increase in idiosyncratic risk, investor exit, and persistently elevated alphas and Sharpe ratios. The selection effect from higher expertise agents' more favorable Sharpe ratios is unique to our model and key to our main results.

Managers often overreact to revenue fluctuations, leading to unnecessary workforce adjustments and increased training costs. This study examines how board governance influences firms’ employment sensitivity to revenue fluctuations. Analyzing global board reforms, we find that board reforms significantly reduce managerial overreaction to revenue fluctuations. Utilizing recent difference-in-differences estimators that address heterogeneous treatment effects, we ensure the robustness of our results. The reduction in employment sensitivity is more pronounced when board reforms strengthen the independence of boards and audit committees, particularly in jurisdictions with weaker board efficacy, shareholder, and employment protection legislation. Enhanced effects are observed in firms with initially lower board independence and rapid reform compliance, in entities experiencing greater information asymmetry, marked by higher labor intensity, higher pre-reform agency costs and financial constraints, and in firms led by less experienced CEOs or boards with higher male representation.
