Minimum Payments and Debt Paydown in Consumer Credit Cards
Abstract
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. We exploit changes in issuers' minimum payment formulas to distinguish
between liquidity constraints and anchoring as explanations for the prevalence of
near-minimum payments. At least 10% of all accounts respond more to the for-
mula changes than expected based on liquidity constraints alone, representing a
lower bound on the role of anchoring. Using a back-of-envelope calculation, we esti-
mate that anchoring consumers would save at least $570 million per year in interest
charges if all issuers adopted the highest observed minimum payment formula in
our sample. Disclosures implemented by the CARD Act, an example of one poten-
tial policy solution to anchoring, resulted in fewer than 1% of accounts adopting
an alternative suggested payment. Our results show that the design and salience
of contract terms in credit products have signicant impacts on household balance
sheets.
