Platform competition in two-sided markets: the case of payment networks

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 networks, and alternative assumptions about multihoming and consumer preferences. We find that competition unambiguously increases consumer and merchant welfare. We extend this analysis to competition among payment networks providing different payment instruments and find similar results.

Payments-related intraday credit differentials and the emergence of a vehicle currency

The U.S. dollar serves as a vehicle currency or medium of exchange in the global foreign exchange markets. After reviewing some of the existing theories on vehicle currencies, the hypothesis put forth is that the dollar's role is linked to the relatively low cost of payments-related intraday credit available to payment system participants. Differences in the types of measures used by payment system operators to reduce settlement and systemic risk in the payment system give rise to liquidity differentials between currencies. ; After reviewing the types of intraday credit facilities extended to ...

Why do banks reward their customers to use their credit cards?

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 with an average cash-back reward of $25, spending and debt increases by $79 and $191 a month, respectively during the first quarter. Furthermore, we find that cardholders who do not use their card prior to the cash-back program increase their spending and debt more than cardholders with debt prior to ...

Regulating two-sided markets: an empirical investigation

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 regulation. We find that consumer and merchant welfare improved because of increased consumer and merchant adoption leading to greater usage of payment cards. We also find that bank revenues increased when interchange fees were reduced although these results are critically dependent on merchant ...

Working Paper
Managerial incentives and financial contagion

This paper proposes a framework to examine the comovements of asset prices with seemingly unrelated fundamentals, as an outcome of the optimal portfolio strategies of large institutional fund managers. In emerging markets, the dominant presence of dedicated fund managers whose compensation is linked to the outperformance of their portfolio relative to a benchmark index, and of global fund managers whose compensation is linked to the absolute returns of their portfolios, leads to portfolio decisions that result in systematic interactions between asset prices even in the absence of asymmetric ...
