Using a simple model of two-sided markets, we show that, in the social optimum, platform pricing leads to an inherent cost recovery problem. This result is driven by the positive externality of participation that users on either side of the market exert on the opposite side. The contribution of...

We derive a stationary equilibrium in a two-player multi-stage game with endogenous discounting. At each stage, the probability to reach the next stage is determined by the players' current actions. We assume that the players are myopic in the sense that they take the future strategies of their...

In two-sided markets, one widely observes skewed pricing strategies, in which the price mark-up is much higher on one side of the market than the other. Using a simple model of two-sided markets, we show that, under constant elasticity of demand, skewed pricing is indeed pro?t maximizing. The...

This paper estimates the relation between bank profitability and economic downturns using a theoretical model that takes into account the bank's lending history as well as amortization and losses on outstanding loans. We focus on total bank profits and its components: net interest income, other...

Debit cards in Europe replace many medium value cash payments while stored value cards were designed to replace small value cash transac-tions. Unit cost considerations dictated a two-card (or single card) dual technology approach to cash replacement since unit costs were too high to use debit...

This paper discusses various theoretic concepts which play a role in assessing the public benefits of Target, the large value RTGS payment network operated by the Eurosystem. These concepts touch upon natural monopoly, network externalities, competition and contestability, as well as economies...

There are numerous ways to indicate the degree of banking competition across countries. Antitrust authorities rely on the structure-conduct-performance paradigm while academics prefer price mark-ups (Lerner index) or correlations of input costs with output prices (H-statistic). These measures...

In this article, we survey the recent theoretical literature on payment cards and study their implications for public policy. Payment card networks have faced regulatory scrutiny in several countries regarding the setting of various fees including interchange fees fees paid by the merchant's...

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...

We develop a model of two-sided markets that illustrates the role of bargaining power between the two sides of the market. We are interested in the profit maximizing usage fees set by identical duopolistic platforms which engage in homogeneous, Bertrand-type competition. We find that for a...
