Two-sided market theory predicts that platforms may subsidize the participation of one type of agent by extracting surplus from another type to internalize indirect network externalities. However, few empirical studies exist to evaluate the impact of government intervention in these markets. We...

This thesis strives to offer new insights in two main areas. First, in the well-researched domain of payment cards chapters 2 and 3 investigate an aspect that has hitherto been scantly examined, namely, the fact that merchant usage fees differ substantially among merchant sectors. Additionally,...

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...

Microfinance can be an important tool for fighting global poverty by increasing access to loans and possibly lowering interest rates through microlending. However, the dominant mechanism used by online microfinance platforms, in which intermediaries administer loans, has profound implications...

We consider debit and credit card networks. Our contribution is to introduce the role of consumer credit into these payment networks, and to assess the way this affects competition and equilibrium fees. We analyze a situation in which overdrafts are associated with current accounts and debit...

The provision of retail payment services is complex with many participants engaging in a series of interrelated bilateral transactions and subject to large economies of scale and scope along with strong adoption, usage and network externalities. This makes sound public policy difficult. We focus...

In this study, a multi-party payment card network model is constructed to explore the determination of merchant and interchange fees, thereby extending Langlet's (2009) observation of unitary payment systems. The focus of this analysis was on the impact of consumer price elasticity, the relative...

This paper investigates the determination of the merchant usage fee of a monopolistic unitary payment card network based on characteristics of the downstream market. Merchants engage in Bertrand price competition that allows for an observation of heterogeneous products. We find that the payment...
