Market Power gives a firm the ability to employ anti-competitive tactics like predatory pricing without losing customers to competitors. During testimony on H.R. 2382, the Representative of The Merchants Payment Coalition stated that “there is no competitive market for interchange fees – just naked price fixing”. On the other side, the Representative from The Electronic Payments Coalition called interchange an “important element(s) of the successful, competitive banking experience” adding that “interchange reflects a merchant’s fair share of the costs” (sic.) of the system.
Last weeks GAO report found that Merchants’ are in fact paying more to accept credit cards, but also added that “network competition in the credit card market may be contributing to rising interchange rates”.
Two-sided markets exhibit “Network Effects” when two groups of users are attracted to each other, in this case retailers who accept payment and consumers who make payment. “Cross- Side Network Effects” occur when enough users are attracted to one side that the other side will pay dearly to reach them. In this case, retailers are the “money side” and they pay to accept cards as a form of payment, while consumers are the “subsidy side” who receive incentives to use the cards as a form of payment. Linking these two groups together is the primary value of the payment platform creating powerful Cross-Side Effects.
Retailers’ accept cards as payment because so many consumers use cards for payment. Competition between card issuing banks to capture consumers, and networks to capture banks is intense as evidenced by the multiple offers for high earning rewards credit and debit products and their users. Retailers ultimately see the cost of this competition reflected in rising interchange fees, particularly the higher rate fees for reward based programs. The question is; does this competition between networks and financial institutions for the consumers’ payment business justify the increasing rates paid by retailers to accept these forms of payment or does it constitute a monopolistic example of a market failure?
