Modeling to Inform Economy-Wide Pandemic Policy: Bringing Epidemiologists and Economists Together
Facing unprecedented uncertainty and drastic trade-offs between public health and other forms of human well-being, policymakers during the Covid-19 pandemic have sought the guidance of epidemiologists and economists. Unfortunately, while both groups of scientists use many of the same basic mathematical tools, the models they develop to inform policy tend to rely on different sets of assumptions and, thus, often lead to different policy conclusions. This divergence in policy recommendations can lead to uncertainty and confusion, opening the door to disinformation, distrust of institutions, and ...

Loan commitments and private firms
Bank lending is an important source of funding for firms. Most loans are in the form of credit lines. Empirical studies of line demand have been complicated by their use of data on publicly traded firms, which have a wide menu of financing options. We avoid this problem by using a unique proprietary data set from a large financial institution of loan commitments made to 712 privately-held firms. We test Martin and Santomero's (1997) model, in which lines give firms the speed and flexibility to pursue investment opportunities. Our findings are consistent with their predictions. Firms facing ...

Serving the Underserved: Microcredit as a Pathway to Commercial Banks
A large-scale microcredit expansion program---together with a credit bureau accessible to all lenders---can enable unbanked borrowers to build a credit history, facilitating their transition to commercial banks. Loan-level data from Rwanda show the program improved access to credit and reduced poverty. A sizable share of first-time borrowers switched to commercial banks, which cream-skim less risky borrowers and grant them larger, cheaper, and longer-maturity loans. Switchers have lower default risk than non-switchers and are not riskier than other bank borrowers. Switchers also obtain better ...

Who Pays For Your Rewards? Redistribution in the Credit Card Market
We study credit card rewards as an ideal laboratory to quantify redistribution between consumers in retail financial markets. Comparing cards with and without rewards, we find that, regardless of income, sophisticated individuals profit from reward credit cards at the expense of naive consumers. To probe the underlying mechanisms, we exploit bank-initiated account limit increases at the card level and show that reward cards induce more spending, leaving naive consumers with higher unpaid balances. Naive consumers also follow a sub-optimal balance-matching heuristic when repaying their credit ...

Related Exposures to Distressed Borrowers and Bank Lending
We study how banks’ exposure to a large set of related and suddenly-distressed borrowers impacts their commercial lending and risk taking. Using Mexican credit registry data, we examine the effect of the 2014 collapse in energy prices. After this shock, energy-exposed banks—regardless of their ex-ante financial health—raise further their exposure to the energy sector by expanding lending at looser credit terms to borrowers with higher expected losses, while recapitalizing through retained earnings. The shock is transmitted to non-energy firms—despite price controls on retail-energy ...

Owe a Bank Millions, the Bank Has a Problem: Credit Concentration in Bad Times
How does a bank react when a substantial share of its borrowers suffer a large negative shock? To answer this question we exploit the 2014 collapse of energy prices using the universe of Mexican commercial bank loans. We show that, after the drop in energy prices, banks exposed to the energy sector increased their exposure to these borrowers even more, relaxing credit margins to their larger debtors in the sector. An increase of one standard deviation in a bank's ex-ante exposure to the energy sector increased the loan volume to borrowers in the sector by 18 percent and reduced interest rates ...

How do private firms use credit lines?
The authors find that firms that face higher upfront commitment fees, risk premium spreads or usage fees have smaller credit lines, while those with higher overdraft fees have larger ones. Firms with greater profit growth in the past have larger credit lines, while those with more internal funds or higher volatility in profit growth have smaller credit lines. The results for line utilization are quite similar.

The asset-backed securities markets, the crisis and TALF
The authors explain the role of asset-backed securities markets in generating credit and liquidity and how this role was disrupted during the financial crisis. They discuss the implementation of the Term Asset-Backed Securities Loan Facility (TALF) and argue that this program helped reestablish the ABS markets and the credit supply. and the reversion to a stable fiscal regime.
