Credit Card Competition and Naive Hyperbolic Consumers

Abstract

I explain the credit card market’s observed systematic pricing patterns by examining time-inconsistent consumers. I find that time inconsistency steers the competition from long-term borrowing contingent prices to short-term noncontingent ones. This pattern occurs because the consumer in the contracting period underestimates the future charges, and therefore pays attention only to short-term price elements, such as annual fees. The consumer’s risk of default also plays a role in determining who gets which contract.
