Firms may pursue non-meritocratic promotion policies at the cost of lower profitability, if they yield private benefits of control. Corporate governance standards that limit these private benefits favor meritocratic promotions and therefore encourage workers’ skill acquisition. Managerial incentive pay has ambiguous effects on workers’ skill acquisition: it fosters the supply of skilled labor, while reducing firms’ willingness to promote skilled workers to managerial positions. Social welfare increases with the share of meritocratic firms, but not necessarily with governance standards: small reforms generate losers and gainers, and may on balance lower welfare, while drastic enough reforms can generate Pareto improvements.

Using survey data on secured funding arrangements provided by broker–dealers for their clients—a class of contracts that includes bilateral repo—we document that financing rates, collateral haircuts, lending maturities, and position limits move strongly together over time and across asset classes. Liquidity of the underlying securities, as opposed to their volatility or credit risk, is the main driver of this behavior, with dealer balance-sheet constraints also playing a role in the funding of less-liquid security types. A simple model of dealer–client interaction rationalizes these findings. Instrumenting with changes in market conventions, we find that funding conditions had little effect on cash securities markets between 2011 and 2019, but the tightening of terms during the market stress of early 2020 likely impaired liquidity and reduced asset returns to some degree.

We investigate whether managers’ intrinsic incentives affect firms’ environmental policies. Exploiting within-facility variation in facility-to-CEO-birthplace distances, we find that facilities located near CEOs’ birthplaces experience toxic emission reductions relative to those farther away. This is achieved by reducing waste generation at source rather than by downsizing operations or substituting pollution across locations. The effect is strongest for hometown facilities in high-polluting areas, and in firms with higher cash holdings and with CEOs with weaker pay incentives. Our results suggest that local representation in management could be a powerful means of encouraging corporate pollution abatement.

We document that implied volatility (IV) curves of short-term equity options frequently become concave prior to earnings announcements day (EAD), typically reflecting a bimodal risk-neutral distribution for the underlying stock price. Firms with concave IV curves exhibit significantly higher absolute stock returns on EAD and higher realized volatility after the announcement, rendering concavity an ex-ante signal for event risk. Returns on delta-neutral straddles, delta-neutral strangles, and delta- and vega-neutral calendar straddles are negative and significantly lower in the presence of concave IV curves, showing that investors pay a substantial premium to hedge against the gamma risk arising from this event.

We provide causal evidence on the effects of mandated board independence. We compare firms that replace existing non-independent directors to firms that retain these directors by reclassifying them as independent. Reclassification eligibility, being largely predetermined, offers quasi-exogenous variation in compliance strategies. We show that firms required to replace insiders perform worse post-mandate, driven by increased operational costs and reduced labor efficiency. Boards of non-reclassifying firms retain fewer former employees and replace them with directors more likely to join monitoring-focused committees, emphasizing the shift from advising to monitoring. Overall, these findings suggest that firm-specific director expertise contributes materially to performance and is consistent with pre-mandate board compositions optimized to balance benefits of enhanced monitoring against costs of reduced advisory capacity. We rule out alternative explanations, including adjustment costs due to director turnover and co-option. Our study underscores the importance of allowing firms’ flexibility in governance structures and cautions against uniform mandates.

This article examines how biased income expectations affect annual contributions to retirement accounts, highlighting variations across income levels. Empirical findings show that low-income workers are generally pessimistic about future earnings, whereas high-income workers tend to be overly optimistic. I develop a lifecycle model that merges these expectation biases with US 401(k) plan features. The model reveals that biased expectations can account for observed delays in retirement contributions, which increase gradually with tenure. Contributions rise at different rates, with low-income workers starting later than high-income workers. Policy simulations indicate that automatic enrollment boosts initial contributions but results in a relative decline compared to active enrollment. Nonetheless, cumulative savings increase by 4.8 percent on average, with gains surpassing 10 percent for the lowest income quartile. These results highlight the significance of addressing income expectations in retirement policies and show that automatic enrollment can enhance welfare, particularly for lower-income individuals.

This article studies the optimal design of bank capital regulations when capital markets are subject to adverse selection. I show how the implementation of capital requirements can eliminate the information frictions that make raising capital costly by screening banks to reveal their private information to the market. The optimal regulations induce information revelation via recapitalization programs when the banking sector is weak and pool the banks’ private information via uniform capital requirements otherwise. Optimal capital requirements are linked to the securities issued to meet them, demonstrating potential welfare gains from incorporating more and less informationally sensitive securities into the design of capital regulations. Finally, the analysis generates insights into the joint design of equity capital requirements and additional tier 1 capital securities.

I document that the network structure of the online economy significantly contributes to rising industry concentration. Firms that are central in the online economy benefit more from increased economies of scale, decreased search costs, and network effects resulting from digitalization. Industries with firms that are more central become more concentrated and central firms have larger increases in market share. These results are driven by firms’ ability to generate revenue, as evidenced by central firms earning higher risk-adjusted returns and having more positive earnings surprises. Centrality is also associated with increasing productivity, but profitability only increases for central firms in business-to-consumer industries.

This study introduces a novel mood metric—blockbuster movie releases—and investigates its correlation with stock market dynamics. We document a significant positive correlation between blockbuster movie releases and US stock market returns in the subsequent week. This pattern remains robust across various robustness tests both in-sample and out-of-sample. The changes in weekly box office revenue and increased Internet searches for movie-related terms further affirm this relationship. Moreover, releases of blockbuster movies predict lower expected market volatility and risk aversion. The positive predictive effect on market returns is also evident in international markets.

This article explores the influence of single-child CEOs on corporate innovation and culture within the context of China’s one-child policy. Utilizing multiple identification strategies, we find that firms led by single-child CEOs invest significantly less in innovation and generate fewer and lower-impact patents. Examining the underlying economic mechanisms, we find that these CEOs foster a corporate culture that discourages trust and collaboration, leading to increased inventor departures. Additionally, firms under their leadership exhibit lower idiosyncratic risk, aligning with the typically cautious behavior of only children. Our analysis demonstrates that these outcomes are primarily driven by behavioral traits associated with being an only child, including self-centeredness, reduced team orientation, and heightened risk aversion. Overall, the study sheds light on how the singular upbringing of single-child CEOs shapes corporate behavior and performance, revealing the broader, enduring economic consequences of national population policies.
