In this article, we construct a model to study competing payment networks, where networks offer differentiated products in terms of benefits to consumers and merchants. We study market equilibria for a variety of market structures: duopolistic competition and cartel, symmetric and asymmetric...

Credit cards provide benefits to consumers and merchants not provided by other payment instruments as evidenced by their explosive growth in the number and value of transactions over the last 20 years. Recently, credit card networks have come under scrutiny from regulators and antitrust...

We model side payments in a competitive credit-card market. If competitive retailers charge a single (higher) price to cover the cost of accepting cards, banks must subsidize convenience users to prevent them from defecting to merchants who do not accept cards. The side payments will be financed...

Over the last decade, consumers have tripled their use of credit cards as more merchants have increased their acceptance of them. This increase suggests that incentives in today's marketplace favor greater credit card use by consumers and acceptance by merchants. In this paper, we study the set...

In this paper, we provide a framework to study the creation and adoption of innovations by payment providers and processors. We identify several motivating factors for banks and nonbanks to invest in payment innovations. In addition, we discuss the evolutionary process of payment innovations...

This paper investigates systemic risk in multilateral netting payments systems. A four-period model is constructed to investigate the effects of random liquidity shocks. There are three different types of agents in this model: banks, the payments system operator, and the central bank. Banks pay...
