Knowledge that Transforms

Corporate credit lines are drawn more heavily when funding markets are stressed. This elevates expected bank funding costs. We show that credit supply is dampened by the associated debt‐overhang cost to bank shareholders. Until 2022, this impact was reduced by linking the interest paid on lines to a credit‐sensitive reference rate like the London interbank offered rate (LIBOR). We show that transition to risk‐free reference rates may exacerbate this friction. The adverse impact on credit supply is offset if drawdowns are expected to be deposited at the same bank, which happened at some of the largest banks during the global financial crisis and COVID recession.

Based on a comprehensive data set of classified (staggered) boards covering nearly all U.S. public firms from 1991 to 2020, we show that contrary to conventional wisdom, the use of classified boards remains widespread. Moreover, classified board usage over a firm's life cycle depends significantly on the decade the firm matured or year it went public. While classified boards were rarely removed in the 1990s, firms became more likely to declassify as they matured during the following decades. Decreased collective action costs and increased innovation‐related investments, institutional ownership, and scrutiny of governance contributed to this more dynamic adjustment.

We show that two important issues in empirical asset pricing—the presence of weak factors and the selection of test assets—are deeply connected. Since weak factors are those to which test assets have limited exposure, an appropriate selection of test assets can improve the strength of factors. Building on this insight, we introduce supervised principal component analysis (SPCA), a methodology that iterates supervised selection, principal‐component estimation, and factor projection. It enables risk premia estimation and factor model diagnosis even when weak factors are present and not all factors are observed. We establish SPCA's asymptotic properties and showcase its empirical applications.

We use arbitrage activity in equity, fixed income, and foreign exchange markets to characterize the frictions and constraints facing intermediaries. The average pairwise correlation between the 32 arbitrage spreads that we study is 22%. These low correlations are inconsistent with canonical intermediary asset pricing models. We show that at least two types of segmentation drive arbitrage dynamics. First, funding is segmented—certain trades rely on specific funding sources, making their arbitrage spreads sensitive to localized funding shocks. Second, balance sheets are segmented—intermediaries specialize in certain trades, so arbitrage spreads are sensitive to idiosyncratic balance‐sheet shocks.

This paper uses new data to provide a comprehensive view of repo activity during the 2007 global financial crisis. We show that activity declined much more in the bilateral segment of the market than in the tri‐party segment. Surprisingly, a large share of the decline in activity is driven by repos backed by Treasury securities. Further, a disproportionate share of the decline in repo activity is connected to securities dealer's market‐making activity. In particular, the evidence suggests that at least part of the decline is not driven by clients pulling away from securities dealers because of counterparty credit concerns.

Using a novel data set of realized syndicated loan cash flows and a risk‐adjustment methodology adapted from the private equity literature, I provide a measure of risk‐adjusted returns for bank loan cash flows. Banks, on average, generate 180 basis points in gross risk‐adjusted returns and add $75 million of value annually to their loan portfolios. Banks earn higher returns when they lend to financially constrained borrowers, and the risk‐adjusted performance of bank loan portfolios exhibits persistence. However, banks require higher risk‐adjusted returns when facing their own financing frictions, and shareholders earn nearly zero net risk‐adjusted returns once bank staff are compensated for their lending effort. Overall, these findings suggest that banks provide valuable services to mitigate borrowers' financing frictions, and the present value of loan cash flows pays for the costs of providing these services.

The paper examines the decision‐making, compensation, and turnover of female CEOs in U.S. hospitals. Contrary to the literature on lower‐ranked executives and directors in public firms, there is no evidence that gender differences in preferences for risk or altruism affect decision‐making of hospital CEOs: corporate policies do not shift when women take (or leave) office, and male and female CEOs respond similarly to a major financial shock. However, female CEOs earn lower salaries, face flatter pay‐for‐performance incentives, and exhibit greater turnover after poor performance. Hospital boards behave as though they perceive female CEOs as less productive.

We study the impact of the U.S. money market fund reform implemented in October 2016 on global banks' funding supply and business activities. We show that the reform induced a large negative wholesale funding shock for global banks. In contrast to the conventional bank lending channel, the primary response of global banks to the reform was a cutback in arbitrage positions that relied on unsecured funding, rather than a reduction in loan provision. We discuss the role of postcrisis liquidity regulations and unconventional monetary policy in explaining our findings, and implications for banks' business models and deposit competition.

We empirically analyze firm‐level uncertainty generated from extreme weather events, guided by a theoretical framework. Stock options of firms with establishments in a hurricane's (forecast) landfall region exhibit large implied volatility increases, reflecting significant uncertainty (before) after impact. Volatility risk premium dynamics reveal that investors underestimate such uncertainty. This underreaction diminishes for hurricanes after Sandy, a salient event that struck the U.S. financial center. Despite constituting idiosyncratic shocks, hurricanes affect hit firms' expected stock returns. Textual analysis of calls between firm management, analysts, and investors reveals that discussions about hurricane impacts remain elevated throughout the long‐lasting high‐uncertainty period after landfall.

We propose a theory of banking in which banks cannot perfectly control deposit flows. Facing uninsurable loan and deposit shocks, banks dynamically manage lending, wholesale funding, deposits, and equity. Deposits create value by lowering funding costs. However, when the bank is undercapitalized and at risk of breaching leverage requirements, the marginal value of deposits can turn negative as deposit inflows, by raising leverage, increase the likelihood of costly equity issuance. Banks' inability to fully control leverage distinguishes them from nondepository intermediaries. Our model suggests a reevaluation of leverage regulations and offers new perspectives on banking in a low‐interest‐rate environment.
