| Abstract: | Why are bank card interest rates sticky? One explanation is bank card consumer irrationality, a potentially significant market failure requiring government intervention. Alternate explanations focus on efficient market forces. The 1989 Federal Reserve Survey of Consumer Finances data are not consistent with the consumer irrationality hypothesis. The data are consistent with a market-based model of demand for balances and suggest that consumers may rationally eschew search because small outstanding balances imply low returns to search. |
