Time to Cut Up Those Debit Cards? Effect of Payment Mode on Willingness to Spend
Financial industry data indicate that consumers increasingly prefer debit cards over credit cards, especially as a means of enforcing financial self-discipline. Given prior research suggesting that credit cards act as spending facilitating stimuli, this move toward reduced credit card use would appear to be in the right direction. Ironically, however, the same logos that were implicated in facilitating spending with credit cards are the logos that appear on debit cards. In what should serve as an eye-opener to consumers, it is found that exposure to debit card logos does result in an increased willingness to spend, similar to credit cards.

Consumer Rationality and Credit Cards
Borrowing on credit cards at high interest rates might appear irrational. However, even low transactions costs can make credit cards attractive relative to bank loans. Credit cards also provide liquidity services by allowing consumers to avoid some of the opportunity costs of holding money. The effect of alternative interest rates on the demand for card debits can explain why credit card interest rates only partially reflect changes in the cost of funds. Credit card interest rates that are inflexible relative to the cost of funds are not inconsistent with a competitive equilibrium that yields zero profits for the marginal entrant.

The Credit Card Debt Puzzle: The Role of Preferences, Credit Access Risk, and Financial Literacy
Abstract. We use the 1979 National Longitudinal Survey of Youth to revisit what is termed the credit card debt puzzle: why consumers simultaneously co-hold high-interest credit card debt and low-interest assets that could be used to pay down this debt. Relative to individuals with no credit card debt but positive liquid assets, borrower-savers have very different perceptions of future credit access risk and use credit cards for precautionary motives. Moreover, changing perceptions about credit access risk are essential for predicting transitions among the two groups. Preferences and the composition of financial portfolios also play a role in these transitions.
