of the Center for Responsible Lending has written Credit Card Clarity: CARD Act Reform Works. Here's the abstract:
This research studies the effect of the Credit CARD Act of 2009 on pricing, transparency, and credit availability.This report’s findings refute negative claims by the credit card industry that new credit card rules have restricted access to consumer credit and raised its cost.These claims rely on limited data that do not accurately capture the cost or availability of credit extended to consumers.
This study uses multiple data sets and methods and consistently finds that the CARD Act has not caused prices to rise or credit to constrict. The difference between the stated rate on credit card solicitations and the rate consumers actually paid widened to unprecedented levels by 2004 and stayed at those levels through 2008. This difference narrowed markedly in the wake of reform, with stated prices on solicitations moving much closer to actual prices.
This study also finds that, in the year since the CARD Act’s implementation, actual prices have remained stable and available credit has not tightened beyond what would be expected from the economic downturn. Because price transparency fosters competition, the long-term effect of the CARD Act is likely to be lower costs for consumers.
