Abstract When a consumer pays by card, the merchant’s bank pays to the consumer’s bank an interchange fee. In this article, we construct a general model of a card platform that unifies the literature on interchange fees. We enrich the existing frameworks by analyzing the choice of the...

Abstract This paper considers the organization of a single (domestic) payment system. When card issuers that are members of a payment system set their fees individually, this gives rise to a free-riding problem, as in providing access to different customers, card issuers are complements from the...

Abstract This paper presents a first estimation of the tourist test threshold for interchange fees that makes Peruvian small merchants indifferent between accepting cash and debit cards at the point of sale. We use the tourist test model (initially proposed by Rochet and Tirole), including tax...

Significant attention worldwide has been paid to the regulation of credit card interchange fees. In part, this attention has followed concerns expressed about the level of these fees in Europe, the U.S. and Australia. The Reserve Bank of Australia recently conducted an extensive inquiry into the...

The paper investigates, in a non-technical fashion, the economic determinants of interchange fees in payment card systems and the potential need for their regulation. Among other things, it demonstrates that the proposal for a cost-based regulation of interchange fees relies on an erroneous,...

We consider an unregulated incumbent who owns a broadband infrastructure and decides on how much access to provide to a potential entrant. The level of access determines the amount of investment the entrant needs to undertake to enter the market, and the intensity of post-entry competition. We...

Abstract We propose a model of Bertrand competition in which consumers choose firms based on prices and qualities. Service quality depends on congestion, which is a function of capacity and output. We first present theoretical properties of the model. Next, we calibrate the model to the wireless...

Abstract Net neutrality or “Open Internet” rulemaking has been ongoing for more than a decade. Some 50 nations have adopted formal rules including the US (then repealed), the European Union, India, and many countries in Latin America. Among other arguments, it is asserted that net neutrality...

The FCC is currently considering whether it should adopt a uniform rate for pole attachment services for broadband services. Based on Ramsey pricing principles, we find that while historical differences in rates were sensible, technological convergence dictates that broadband providers should...

Proposals to increase regulation of mobile wireless services, for example, by applying “net neutrality" regulation, are often based on claims that such regulation would enhance innovation and increase consumer choice. In fact, they would have the opposite effect. The business practices that...
