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...

We study the effect of government encouraged or mandated interchange fee ceilings on consumer and merchant adoption and usage of payment cards in an economy where card acceptance is far from complete. We believe that we are the first to use bank- level data to study the impact of interchange fee...

In this article, we construct a two-period model to investigate what market conditions would support a credit card equilibrium given two commonly observed credit card pricing conventions consumers rarely are charged higher prices for using their credit cards and if they payoff their credit card...

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...

During the last decade, debit card transactions grew rapidly in most advanced countries. While check usage declined and has almost disappeared in some countries, the stock of currency in circulation has not declined as fast. We use panel estimation techniques to analyze the change in...

Using a unique administrative level dataset from a large and diverse U.S. financial institution, we test the impact of rewards on credit card spending and debt. Specifically, we study the impact of cash-back rewards on individuals before and during their enrollment in the program. We find that...
