Purpose - This paper aims to provide a first overview of important implications of payment models for next-generation mobile service platforms (NextGen MSPs).Methodology and approach - Our starting point is an existing set of mobile payment models. We modify and expand on these models, in order...

The falling use of cash and the advent of digital technologies support the possibility of reconfiguration of monetary transactions without any intermediation of physical monetary tokens.

In our paper, we introduce the Hungarian Payment System Model (HUPS), a computable general equilibrium model with detailed payment services which can be used for policy evaluation and forecast. In the last years, several studies investigated different aspects of payment systems and some papers...

Can competition work among privately issued fiat currencies such as Bitcoin or Ethereum? Only sometimes. To show this, we build a model of competition among privately issued fiat currencies. We modify the current workhorse of monetary economics, the Lagos-Wright environment, by including...
