I study how intra-household frictions and anchoring contribute to the credit card debt puzzle, the co-holding of high-cost debt and low-yield liquid assets. First, I find couples co-hold 42 percent more as units than as individuals relative to income. Moreover, in a natural experiment, couples do not cooperate to reduce high-cost debt, suggesting that intra-household frictions contribute to co-holding. Second, I find individuals who regularly make credit card debt payments equal to or near the minimum account for 59 percent of individual co-holding. The evidence suggests anchoring to the minimum payment contributes to co-holding via these low payments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
