[NEW] How Much Do Small Businesses Rely on Personal Credit? (with Julia Fonseca)
We estimate that U.S. entrepreneurs were able to substitute more than half of the supply contraction in small business credit caused by large banks after the 2008 financial crisis by increasing their use of personal credit.
[NEW] The Online Payday Loan Premium (with Filipe Correia and Peter Han)
We find that prices for online payday loans are about 100% APR higher than storefront loans. This premium is not explained by loan or customer characteristics, but is at least partially attributable to higher default risk.
[NEW] To Pay or Autopay? Fintech Innovation and Credit Card Payments
Using data from a fintech credit card company, I estimate that autopay has significant effects on consumer payment behavior. Moving from 0 to 100 percent autopay enrollment increases the fraction of minimum payments by 20 to 30 pp, and decreases overall payment amounts conditional on not charging off.
Bankruptcy and the COVID-19 Crisis (with Jeyul Yang, Ben Iverson, and Renhao Jiang)
[Paper] [Slides] [Video] [Blog]
We document large and persistent declines in bankruptcy rates for both households and small businesses after the onset of the crisis in mid-March, in a surprising reversal of the close historical relationship between bankruptcy and unemployment rates in both the time series and cross section.
When Is It Hard to Make Ends Meet? (with Brian Baugh)
[Paper] [Slides] [Video]
Households are more likely to experience financial shortfalls during predictably longer pay periods, and when they have a greater mismatch between the timing of income and expenditure commitments.
The Effects of Disclosure and Enforcement on Payday Lending in Texas (with Kathleen Burke)
Journal of Financial Economics, 145 (2B), 2022. [Journal link] [NBER WP] [NBER Digest (non-technical)] [SSRN] [Slides]
Statewide disclosures led to a significant and persistent 13% decline in payday loan volume, and city ordinances in Austin and Dallas led to significant declines driven by the start of enforcement rather than the effective date of regulation.
The Economic Consequences of Bankruptcy Reform (with Tal Gross, Ray Kluender, Feng Liu, and Matthew Notowidigdo)
American Economic Review, 111 (7), 2021. [Journal link] [NBER WP] [NBER Digest (non-technical)] [Video]
The Bankruptcy Abuse Prevention and Consumer Protection Act of 2005 significantly reduced aggregate bankruptcy filings and reduced the cost of unsecured credit. A one-percentage-point reduction in filing risk conditional on credit score translates to a 70-100 basis-point decline in the offered interest rate for unsecured credit.

Outstanding Paper Award in Financial Institutions, MFA 2017.
For a sample of over 160,000 bankruptcy filers, the MPC out of liquidity averaged 0.37 between 2004 and 2011, and was 20–30 percent higher between 2007 and 2009 compared to surrounding years.
Minimum Payments and Debt Paydown in Consumer Credit Cards (with Ben Keys)
Journal of Financial Economics, 131 (3), 2019. [Journal link] [NBER WP]
Using a dataset covering one quarter of the U.S. general-purpose credit card market, we document that 29% of accounts regularly make payments at or near the minimum payment, and at least 9% of all accounts anchor to the minimum payment.

Liquidity Constraints and Budgeting Mistakes: Evidence from Social Security Recipients (with Jesse Leary)
Exploiting quasi-random variation in the timing of benefits disbursed by the Social Security Administration, we find that individuals are 35% more likely to take out payday loans during 35-day compared with 28-day pay periods, and 4% less likely to borrow if they are assigned to receive income on the fourth Wednesday compared to the second Wednesday of the month.
