Banks and shadow banks: Competitors or complements?

Journal of Financial Intermediation 2016 27, 118-131
Bank managers can buy risky assets through a regulated bank and through an off-balance sheet special purpose vehicle (SPV). The choice of the preferred entity depends on whether bank managers can lower the cost of SPV funding by guaranteeing SPV returns with bank proceeds. When there are no guarantees, using the SPV is more profitable for high levels of the minimum capital requirement, in which case the SPV crowds out the bank. Contrary, when bank managers guarantee SPV returns, the bank needs to operate for the SPV to take advantage of recourse to the bank’s balance sheet also when the capital requirement is high. The bank and the SPV intermediation become complements.

Competition, Managerial Slack, and Corporate Governance

The Review of Corporate Finance Studies 2015 4(1), 43-68
We model the interaction between product market competition and internal governance at firms. Competition makes it more difficult to infer a manager’s action given the realized output, thus increasing the cost of inducing effort. An exogenous change in the incentive to shirk increases managerial slack. However, the effects on firm value are ambiguous; in particular, firm value can increase as slack increases. As a result, empirical tests that focus on changes in value may not capture changes in the level of slack. We also provide conditions under which increased competition leads all firms to switch from high to low effort.

“Superstitious” Investors

The Review of Asset Pricing Studies 2025 15(1), 1-45
Abstract We reconsider the excess volatility puzzle through the lens of a model in which agents believe they can predict dividend growth when in fact they cannot. Besides excess volatility in the time series, the model explains the value premium, and the explanatory power of the value factor. In support of the model, we show that analysts’ earnings forecasts align with market valuation and that analysts are far more optimistic about growth stocks than they are about value stocks. Using both survey and price data, we show that the same mechanism can explain the excess returns earned by investing in high-interest rate currencies. (JEL G12, G15, G41)

Aggregate Tail Risk and Expected Returns

The Review of Asset Pricing Studies 2018 8(1), 36-76
Do stocks bear a crash risk premium? We examine the empirical performance of the tail index measure from Kelly and Jiang (2014). We find that the tail index explains the cross-section of the discount rate component of returns, but not the cash-flow component. Moreover, in the time series the tail index is uncorrelated with theoretically motivated measures of aggregate uncertainty and systemic risk. In contrast, the tail index Granger causes and is Granger caused by the level of the term structure, and the slope of the term structure Granger causes tail risk.

Firm Finances and the Spread of COVID-19: Evidence from Nursing Homes

The Review of Corporate Finance Studies 2023 12(1), 1-35
Abstract We find that firms’ financial resources play an important role in mitigating the spread of COVID-19. We study nursing homes—whose residents account for over one-third of all U.S. COVID-19 deaths—at a time when investment in risk mitigation was costly and critical. Facilities with less liquidity and those experiencing more severe cash flow shocks had more cases of COVID-19. The importance of cash flow is further supported by tests exploiting state-level variation in Medicaid reimbursement expansion. Evidence on personal protective equipment supplies suggests a lack of financial resources leads to lower investment in risk mitigation.

Economic-State Variation in Uncertainty-Yield Dynamics

The Review of Asset Pricing Studies 2021 11(1), 60-104
Abstract We show there is a much stronger negative, dynamic relation between changes in economic uncertainty and Treasury yields over weaker economic times since at least 1990. We document this economic-state variation in uncertainty-yield dynamics for weekly and monthly change horizons, for nominal yields and real-yield proxies, for multiple economic-state identification methods, and for different economic uncertainty metrics. We present additional findings that suggest short-term fluctuations in precautionary-savings and consumption-smoothing forces are more impactful on interest rate dynamics during weaker economic times, especially relying on surveys of expected economic growth and inflation.

Information: Hard and Soft

The Review of Corporate Finance Studies 2019 8(1), 1-41
Information, which can arrive in multiple forms, is a fundamental component of all financial transactions and markets. We define hard and soft information and describe the relative advantages of each. Hard information is quantitative, is easy to store, and can be transmitted in impersonal ways. Its information content is independent of its collection. As technology changes, the way we collect, process, and communicate information, it changes the structure of markets, the design of financial intermediaries, and the incentives to use or misuse information. We survey the literature to understand how information type influences the continued evolution of financial markets and institutions.

U.S. monetary policy in disarray

Journal of Financial Stability 2014 12, 47-58
Monetary policy became more difficult to characterize during and after the mortgage foreclose and financial crises because of a shift to a new credit policy focused on private sector credit and that relies on traditional commercial banking strategies. The new credit policy broke the tight link that had existed between Fed credit and its effective monetary base, the monetary base that affects monetary aggregates. The Fed has adopted an exit strategy, but the discretionary powers that it followed remain in place as does a mistaken policy on the payment of interest on excess reserves.

Bank lending opportunities and credit standards

Journal of Financial Stability 2008 4(1), 62-87
This article empirically tests the hypothesis that credit-screening standards can be first increasing and then decreasing in the quality of the bank's pool of potential borrowers, which in turn may vary through the business cycle or across different segments of the lending markets. A key implication is that banks with lending opportunities toward the middle of the quality spectrum can have loan portfolios that perform better than do the portfolios of banks with loan-origination opportunities that are either too weak or too strong. Using banks’ volume of secondary-market loan sales as a proxy for the richness of lending opportunities, I find an inverse U-shaped relation between the performance of banks’ loan portfolios and their activity in the loan sales market. The pattern deserves scrutiny for its policy implications, as many regulators hold the view that countercyclical variation in credit standards may have a destabilizing effect on business cycles.
