The Risk of Being a Fallen Angel and the Corporate Dash for Cash in the Midst of COVID

The Review of Corporate Finance Studies 2020 9(3), 430-471 open access
Data on firm-loan-level daily credit line drawdowns in the United States expose a corporate “dash for cash” induced by the COVID-19 pandemic. In the first phase of the crisis, which was characterized by extreme precaution and heightened aggregate risk, all firms drew down bank credit lines and raised cash levels. In the second phase, which followed the adoption of stabilization policies, only the highest-rated firms switched to capital markets to raise cash. Consistent with the risk of becoming a fallen angel, the lowest-quality BBB-rated firms behaved more similarly to non-investment grade firms. The observed corporate behavior reveals the significant impact of credit risk on corporate cash holdings.

Precautionary Hoarding of Liquidity and Interbank Markets: Evidence from the Subprime Crisis

Review of Finance 2013 17(1), 107-160 open access
We study the liquidity demand of large settlement banks in the UK and its effect on the money markets before and during the subprime crisis of 2007–08. We find that the liquidity demand of large settlement banks experienced a 30% increase in the period immediately following August 9 2007, the day when money markets froze, igniting the crisis. Following this shift, liquidity demand had a precautionary nature in that it rose on days of high payment activity and for banks with greater credit risk. This caused overnight interbank rates to rise, an effect virtually absent in the precrisis period.

Caught between Scylla and Charybdis? Regulating Bank Leverage When There Is Rent Seeking and Risk Shifting

The Review of Corporate Finance Studies 2015 5(1), cfv006 open access
We develop a theory of optimal bank leverage in which the benefit of debt in inducing loan monitoring is balanced against the benefit of equity in attenuating risk shifting. However, faced with socially costly correlated bank failures, regulators bail out creditors. Anticipation of this generates multiple equilibria, including one with systemic risk in which banks use excessive leverage to fund correlated, inefficiently risky loans. Limiting leverage and resolving both moral hazards—insufficient loan monitoring and asset substitution—requires a novel two-tiered capital requirement, including a “special capital account” that is unavailable to creditors upon failure.

Corporate Governance Externalities

Review of Finance 2010 14(1), 1-33 open access
When firms compete in the managerial labor market, the choice of corporate governance by a firm affects, and is affected by, the choice of governance by other firms. Firms with weaker governance offer managers more generous incentive compensation, which induces firms with good governance to also overpay their management. Due to this externality, overall level of governance in the economy can be inefficiently low. Poor governance can in fact be employed by incumbent firms to deter entry by new firms. Such corporate governance externalities have important implications for regulatory standards, ownership structure of firms, and the market for corporate control.

Sovereign Debt, Government Myopia, and the Financial Sector

Review of Financial Studies 2013 26(6), 1526-1560 open access
What determines the sustainability of sovereign debt? In this paper, we develop a model where myopic governments seek electoral popularity but can nevertheless commit credibly to service external debt. They do not default when they are poor because they would lose access to debt markets and be forced to reduce spending; they do not default when they become rich because of the adverse consequences to the domestic financial sector. Interestingly, the more myopic a government, the greater the advantage it sees in borrowing, and therefore the less likely it will be to default (in contrast to models where sovereigns repay because they are concerned about their long term reputation). More myopic governments are also likely to tax in a more distortionary way, and create more dependencies between the domestic financial sector and government debt that raise the costs of default. We use the model to explain recent experiences in sovereign debt markets.

Liquidity, Liquidity Everywhere, Not a Drop to Use: Why Flooding Banks with Central Bank Reserves May Not Expand Liquidity

Journal of Finance 2024 79(5), 2943-2991 open access
Central bank balance sheet expansion, through actions like quantitative easing, is run through commercial banks. While this increases liquid central bank reserves held on commercial bank balance sheets, demandable uninsured deposits issued to finance the reserves also increase. Subsequent shrinkage in the central bank balance sheet may entail shrinkage in bank‐held reserves without a commensurate reduction in deposit claims. Furthermore, during episodes of liquidity stress, when many claims on liquidity are called, surplus banks may hoard reserves. As a result, central bank balance sheet expansion may create less additional liquidity than typically thought, and indeed, may increase the probability and severity of episodes of liquidity stress.

On the optimality of resetting executive stock options

Journal of Financial Economics 2000 57(1), 65-101 open access
The practice of resetting strike prices on underwater executive stock options has drawn criticism for weakening managerial incentives. Our model shows that although the anticipation of resetting can negatively affect initial incentives, resetting can still be an important, value-enhancing aspect of compensation contracts, even from an ex-ante standpoint. In fact, we find that some resetting is almost always optimal. The relative advantages of resetting diminish with greater ability of managers to influence the resetting process, greater relative importance of external factors on stock performance, and lower costs of replacing incumbent managers.

Does the lack of financial stability impair the transmission of monetary policy?

Journal of Financial Economics 2020 138(2), 342-365 open access
We investigate the transmission of central bank liquidity to bank deposits and loan spreads in Europe over the period from January 2006 to June 2010. We find evidence consistent with an impaired transmission channel due to bank risk. Central bank liquidity does not translate into lower loan spreads for high-risk banks for maturities beyond one year, even as it lowers deposit spreads for both high- and low-risk banks. This adversely affects the balance sheets of high-risk bank borrowers, leading to lower payouts, lower capital expenditures, and lower employment. Overall, our results suggest that banks’ capital constraints at the time of an easing of monetary policy pose a challenge to the effectiveness of the bank-lending channel and the central bank's lender of last resort function.

Why Did Bank Stocks Crash during COVID-19?

Review of Financial Studies 2024 37(9), 2627-2684 open access
A two-sided “credit-line channel”—relating to drawdowns and repayments—explains the severe drop and partial subsequent recovery in bank stock prices during the COVID-19 pandemic. Banks with greater exposure to undrawn credit lines saw larger stock price declines but performed better outside of crises periods. Despite deposit inflows, high drawdowns led to reduced bank lending, suggestive of capital encumbrance upon drawdowns. Repayments of credit lines unencumbered capital which explains the stock price recovery starting Q2 2020. Bank provision of credit lines resembles writing put options on aggregate risk, and we propose how to incorporate this feature into bank stress tests.
