Economics of payment cards: a status report

This article surveys the recent theoretical literature on payment cards (focusing on debit and credit cards) and studies this research's possible implications for the current public policy debate over payment card networks and the pricing of their services for both consumers and merchants.Payment systems ; Credit cards

Consumer choice and merchant acceptance of payment media

We study the ability of banks and merchants to influence the consumer's payment instrument choice. Consumers participate in payment card networks to insure themselves against three types of shocks -- income, theft, and their merchant match. Merchants choose which payment instruments to accept based on their production costs and increased profit opportunities. Our key results can be summarized as follows. The structure of prices is determined by the level of the bank's cost to provide payment services including the level of aggregate credit loss, the probability of theft, and the timing of income inflows. We also identify equilibria where the bank finds it profitable to offer one or both payment cards. Our model predicts that when merchants are restricted to charging a uniform price for goods that they sell, the bank benefits while consumers and merchants are worse off. Finally, we compare welfare-maximizing price structures to those that result from the bank's profit-maximizing price structure.Payment systems ; Credit cards ; Consumer credit

Payment network scale economies, SEPA, and cash replacement

The goal of SEPA (Single Euro Payments Area) is to facilitate the emergence of a competitive, intra-European market by making cross-border payments as easy as domestic transactions. With crossborder inter-operability for electronic payments, card transactions will increasingly replace cash and checks for all types of payments. Using different methods, the authors estimate card and other payment network scale economies for Europe. These indicate substantial cost efficiency gains if processing is consolidated across borders rather than "piggybacked" onto existing national operations. Cost reductions likely to induce greater replacement of small value cash transactions are also illustrated.

Consumer credit and payment cards

We consider debit and credit card networks. Our contribution is to introduce the role of consumer credit into these payment networks, and to assess the way this affects competition and equilibrium fees. We analyze a situation in which overdrafts are associated with current accounts and debit cards, and larger credit lines with ‘grace’ periods are associated with credit cards. If we just introduce credit cards, we find their merchant fees depend not only on the networks’ cost of funds and the probability of default, but also on the interest rates of overdrafts. Whilst debit card merchant fees do not depend on funding costs or default risk in a debit-card only world, this changes when they start to compete with credit cards. First, debit merchant acceptance increases with the default probability, even though merchant fees increase. Second, an increase in funding costs causes a surprising increase in debit merchant fees. Effectively, the bank offering the debit card benefits from consumers maintaining a positive current account balance, when they use their credit instead of their debit card. As a result, this complementarity may lead to relatively high debit card merchant fees as the bank discourages debit card acceptance at the margin.

The effect of transaction pricing on the adoption of electronic payments: a cross-country comparison

Pricing should speed up the substitution of low cost electronic payments for expensive paper-based transactions and cash. But by how much? Norway has explicitly priced individual payment transactions and rapidly shifted to electronic payments while the Netherlands has experienced the same shift without direct pricing. Controlling for differences between countries, the authors estimate the incremental effect of pricing on the shift to electronic payments. If users strongly value the improved convenience or security of electronic payments, pricing—viewed negatively by most consumers—may not be necessary to ensure rapid adoption of electronic payments. ; Also issued as Payment Cards Center Discussion Paper No. 05-18Electronic funds transfers ; Prices

Size Matters: Economies of Scale in European Payment Processing

This paper investigates the existence and extent of economies of scale in the European payment processing industry. It is expected that the creation of a Single European Payments Area (SEPA) will spur consolidations and mergers among European payment processors to more fully realize payment economies of scale. We find evidence for the existence of significant economies of scale using data of eight European payment processors during the years 1990-2005. The analysis also reveals that ownership structure is an important factor to explain cost differences across European ACHs.Payment Scale Economies, SEPA, ACHs, ownership
