Summary of preliminary findings
1. We examine four main questions: did disclosures change behavior? Of whom? Persistent? Impact on cardholder debt?
2. Preliminary findings – good newsi. Fewer payments at minimum amount, on aggregateii Some consumers reframed to the 36 month suggestionii. Some consumers reframed to the 36 month suggestioniii. Reframing consumers appear to be most credit constrainediv. They are somewhat persistent
3. Less positive newsi. They are only somewhat persistentii C d t i il l h did t d t l thii. Compared to similar people who did not adopt plan, they
seem to be increasing their amount of debtiii. Moving target

Empirical evidence on framing effects
• “Framing” affects decision‐making in a variety of contexts• 401k choices (Madrian and Shea 2001)401k choices (Madrian and Shea 2001)• Cooperation in experimental settings (Andreoni 1995)• Numeric judgments (Mussweiler and Strack 2000)
• Lab experiments suggest that reframing effects could be substantial for credit cardholders• “Minimum payment” line is excluded for some participants• For revolvers, when a suggested minimum payment was given the average
repayment was £99 (23% of the balance). When no required minimum payment was stated the repayment averaged £175 (40% of the balancepayment was stated, the repayment averaged £175 (40% of the balance (Neil Stewart, “The Cost of Anchoring on Credit Card Minimum Payments”, Psychological Science 20, 39‐41 (2009) )

The new disclosure rules, as written, are a moving target – will they help consumers out of debt?
• If someone makes no new purchases and pays exactly the 36If someone makes no new purchases and pays exactly the 36 month number, they will NOT get out of debt in 36 months:
Th 36 h i l l d h h h ff• The 36 month amount is recalculated each month ‐ the payoff period will always be 36 months away
• With 15.32% APR (non‐reward rate), it will take a member with the average balance ($3900) paying her 36 month amount, followed by “minimum‐minimum” amount, 150 months to getfollowed by minimum minimum amount, 150 months to get out of debt
