Quispe-Torreblanca et al. (2019) on Non-fungible Credit Card Bills

Edika G. Quispe-Torreblanca, Neil Stewart, John Gathergood, and George Loewenstein, “The Red, the Black, and the Plastic: Paying Down Credit Card Debt for Hotels, Not Sofas.Management Science 65(11): 5392-5410, November 2019.

 Is money fungible? Many studies show that the source of money influences how it is spent – for instance, “playing with house money” 

• Consider the repayment of borrowed funds. Presumably the highest interest debt should be most rapidly repaid. 

 But durable goods create a stream of future benefits, so perhaps people can reduce the psychological pain of paying by paying off debts of transient goods more rapidly than debts associated with durable goods. 

 A vacation (a transient good) paid for in advance will be more pleasurable, by this accounting (“prospective accounting”) than the same vacation which is paid for after the fact. 

• People will be more willing to pay interest for a durable good like a clothes dryer. Pre-paying for the dryer does not appreciably raise its hedonic payoff. 

• These mental accounting effects might affect original decisions to make purchases, as well as how repayment occurs.

• A large field experiment is conducted, using UK credit card data. 

 Nondurable goods are indeed much more likely to be paid off at the end of the month than similar bills for durable items – an effect that would be matched by something like a 15% increase in the APR on non-durable debt.
