We test the interest rate sensitivity of subprime credit card borrowers using a unique panel data set from a UK credit card company. What is novel about our contribution is that we were given details of a randomized interest rate experiment conducted by the lender between October 2006 and...

Previous research has found that perceptions of payment security affect consumers' use of payment instruments. We test whether the Target data breach in 2013 was associated with a change in consumers' perceptions of the security of credit cards and debit cards and with subsequent changes in...

We propose a new approach to studying the pass-through of credit expansion policies that focuses on frictions, such as asymmetric information, that arise in the interaction between banks and borrowers. We decompose the effect of changes in banks' cost of funds on aggregate borrowing into the...

This paper studies the sources of suboptimal allocations observed in credit card repayments using a diagnostic laboratory experiment. Using a series of treatments, we present two main findings. First, suboptimal allocations persist in extremely simple choice environments. Particularly, neither...

We build a framework to understand the effects of regulatory interventions in credit markets, such as caps on interest rates and higher compliance costs for lenders. We focus on the credit card market, in which we observe U.S. consumers borrowing at high and very dispersed interest rates,...

We use monthly credit card data from the Federal Reserve's Y-14M reports to study the early impact of the COVID-19 shock on the use and availability of consumer credit. First, we find that in counties severely affected by the pandemic, creditworthy borrowers reduce their credit card balances and...

Using a large panel of credit card accounts, we examine the dynamics of credit card borrowing and repayment in the United States and what these imply for the expected costs of credit card debt to consumers. Our analysis reveals that: (1) credit cards are predominantly used to borrow, (2) card...

Buying a house changes a household's balance sheet by simultaneously reducing liquidity and introducing mortgage payments, which may leave the household more exposed to other shocks. We find that this change affects credit card use in two ways: A debt effect increases credit card spending, while...

We explore the effects of round number preferences in credit card payments. Payments at round numbers are very common: 70% of manual non-full credit card payments are at round numbers. Using minimum payment amounts as a natural experiment for the lower bound on payments, we show stickiness in...
