Further evidence of fragmentation can be observed in a study by Ryan Bubb and Alex Kaufman. 18 The<br />

authors <strong>com</strong>pare the credit card practices of banks to credit unions and find substantial differences. As<br />

shown in Figure 6, credit unions have much more uniform pricing, while bank pricing is highly fragmented.<br />

This is not surprising since the mission of credit unions is to act in the interest of their members, who are<br />

also their borrowers while the mission of for‐profit banks is to maximize profits. Banks have an incentive to<br />

fragment prices in a way that sends powerful signals while raising prices in underweighted areas. Credit<br />

unions may not have as strong an incentive to do so because such fragmentation would in effect be<br />

deceiving their own members. 19<br />

“Shrouded” Costs (or Reductions in Benefits) are Prevalent<br />

Credit cards clearly include numerous shrouded costs. Two that have already been mentioned include<br />

penalty APRs and payment allocation mechanisms. The payment allocation policy utilized by issuers was<br />

found be a shrouded attribute of the product. Consumer understanding was extremely low. When<br />

surveyed, only 3.4% of the public got three basic questions right that were necessary for understanding<br />

19 While credit unions have much less fragmented prices, this practice is not universal. Some credit unions have<br />

offered credit cards in partnership with some of the issuers with the most aggressive pricing (possibly without being<br />

aware of the full implications of their practices). Likewise, in other areas (such as overdraft fees), a number of credit<br />

unions use the same policies as the large banks.<br />
