We use the 2020 Small Business Credit Survey to study the sources of racial disparities in use of the Paycheck Protection Program (PPP). Black-owned firms are 8.9 percentage points less likely to receive PPP loans than observably similar white-owned firms. About 55% of this take-up disparity is explained by a disparity in application propensity, while the remainder is explained by a disparity in approval rates. The finding in prior research that Black-owned firms were less likely than white-owned firms to borrow from banks and more likely to borrow from fintech lenders is driven entirely by application behavior. Conditional on applying for PPP, Black-owned firms are 9.9 percentage points less likely than white-owned firms to apply to banks and 7.8 percentage points more likely to apply to fintechs. However, they face similar average approval disparities at banks (7.4 percentage points) and fintechs (8.4 percentage points). Sorting by Black-owned firms away from banks and toward fintechs is significantly stronger in more racially biased counties, and the bank approval disparity is also larger in more racially biased counties. Thus, to the extent that automation at fintechs reduces racial disparities in PPP take-up, it does so by mitigating disparities in loan application rates, not loan approval rates.
Applications or Approvals: What Drives Racial Disparities in the Paycheck Protection Program?
Sergey Chernenko and David S. Scharfstein. 8/18/2021. “Racial Disparities in the Paycheck Protection Program.” SSRN. Publisher's VersionAbstract
Using a large sample of Florida restaurants, we document significant racial disparities in borrowing through the Paycheck Protection Program (PPP) and investigate the causes of these disparities. Black-owned restaurants are 25% less likely to receive PPP loans. Restaurant location explains 5 percentage points of this differential. Restaurant characteristics explain an additional 10 percentage points of the gap in PPP borrowing. On average, prior borrowing relationships do not explain disparities. The remaining 10% disparity is driven by a 17% disparity in PPP borrowing from banks, which is partially offset by greater borrowing from nonbanks, largely fintechs. Disparities in PPP borrowing cannot be attributed to lower awareness of PPP loans or lower demand for PPP loans by minority-owned restaurants. Black-owned restaurants are significantly less likely to receive bank PPP loans in counties with more racial bias. In these counties, Black-owned restaurants are more likely to substitute to nonbank PPP loans. This substitution, however, is not strong enough to eliminate racial disparities in PPP borrowing. Finally, we show that our findings apply more broadly across industries in a sample of firms that were likely eligible for PPP.
Racial Disparities in the Paycheck Protection Program
Samuel Hanson, David Scharfstein, and Adi Sunderam. 2018. “Social Risk, Fiscal Risk, and the Portfolio of Government Programs.” Review of Financial Studies, 32, 6, Pp. 2341-2382.Abstract
This paper proposes a new approach to social cost-benefit analysis using a model in which a benevolent government chooses risky projects in the presence of market failures and tax distortions.  The government internalizes market failures and therefore perceives project payoffs differently than do individual private actors.  This gives it a "social risk management" motive - projects that generate social benefits are attractive, particularly if those benefits are realized in bad economic states.  However, because of tax distortions, government financing is costly, creating a "fiscal risk management" motive.  Government projects that require large tax-financed outlays are unattractive, particularly if those outlays tend to occur in bad economic times.  At the optimum, the government trades off its social and fiscal risk management motives.  Frictions in government financing create interdependence between two otherwise unrelated government projects.  As in the theory of portfolio choice, the fiscal risk of a project depends on how its fiscal costs covary with the fiscal costs of the government's overall portfolio of projects.  This interdependence means that individual projects should not be evaluated in isolation.

This paper examines the effect of pension policy on the structure of financial systems around the world. In particular, I explore the hypothesis that policies that promote pension savings also promote the development of capital markets. I present a model that endogenizes the extent to which savings are intermediated through banks or capital markets, and derive implications for corporate finance, household finance, banking, and the size of the financial sector. I then present a number of facts that are broadly consistent with the theory and examine a variety of alternative explanations of my findings.

A large share of dollar-denominated lending is done by non-U.S. banks, particularly European banks. We present a model in which such banks cut dollar lending more than euro lending in response to a shock to their credit quality. Because these banks rely on wholesale dollar funding, while raising more of their euro funding through insured retail deposits, the shock leads to a greater withdrawal of dollar funding. Banks can borrow in euros and swap into dollars to make up for the dollar shortfall, but this may lead to violations of covered interest parity (CIP) when there is limited capital to take the other side of the swap trade. In this case, synthetic dollar borrowing becomes expensive, which causes cuts in dollar lending. We test the model in the context of the Eurozone sovereign crisis, which escalated in the second half of 2011 and resulted in U.S. money-market funds sharply reducing the funding provided to European banks. Coincident with the contraction in dollar funding, there were significant violations of euro-dollar CIP. Moreover, dollar lending by Eurozone banks fell relative to their euro lending in both the U.S. and Europe; this was not the case for U.S. global banks. Finally, European banks that were more reliant on money funds experienced bigger declines in dollar lending.

U.S. money market mutual funds (MMFs) are an important source of dollar funding for global financial institutions, particularly those headquartered outside the U.S.  MMFs proved to be a source of considerable instability during the financial crisis of 2007–2009, resulting in extraordinary government support to help stabilize the funding of global financial institutions.  In light of the problems that emerged during the crisis, a number of MMF reforms have been proposed, which we analyze in this paper.  We assume that the main goal of MMF reform is safeguarding global financial stability. In light of this goal, reforms should reduce the ex ante incentives for MMFs to take excessive risk and increase the ex post resilience of MMFs to system-wide runs.  Our analysis suggests that requiring MMFs to have subordinated capital buffers could generate significant financial stability benefits.  Subordinated capital provides MMFs with loss absorption capacity, lowering the probability than an MMF suffers losses large enough to trigger a run, and reduces incentives to take excessive risks.  Other reform alternatives based on market forces, such as converting MMFs to a floating NAV, may be less effective in protecting financial stability.  Our analysis sheds light on the fundamental tensions inherent in regulating the shadow banking system.
Robin Greenwood and David Scharfstein. 2013. “The Growth of Finance.” Journal of Economic Perspectives, 27, 2, Pp. 3-28.Abstract
The U.S. financial services industry grew from 4.9% of GDP in 1980 to 7.9% of GDP in 2007. A sizeable portion of the growth can be explained by rising asset management fees, which in turn were driven by increases in the valuation of tradable assets, particularly equity. Another important factor was growth in fees associated with an expansion in household credit, particularly for residential mortgages. This expansion was itself fueled by the development of non-bank credit intermediation (or "shadow banking").   Whether the growth of the financial sector has been socially beneficial depends on one's view of active asset management, the increase in household credit, and the growth of shadow banking. While recognizing some of the benefits of professional asset management, we are skeptical about the marginal value of active asset management. We then raise concerns about whether the potential benefits of increased access to household credit—the main output of the shadow banking system—are outweighed by the risks inherent in this new approach to credit delivery.
