Virtual Currencies, Micropayments and Monetary Policy: Where Are We Coming from and Where Does the Industry Stand?

Abstract

The exponential growth of the micropayments industry and the expansion of social networks in the last few years have produced the necessary conditions for the birth and growing importance of a distinct object that is fairly new to many disciplines: virtual currencies. The present work is a pioneering study in this field, in which we attempt to survey the main issues and challenges posed to Economic Theory and to the design and implementation of economic policy. Particularly, we are interested in the implications that virtual currencies may have for: 1) The economic principles associated with voluntary holdings of different kinds of money; 2) The rate-of-return dominance by some currencies that may coexist with currencies offering lower real returns; and 3) The state-of-the-art Monetary Dynamic Stochastic General Equilibrium models with micro-foundations. We believe that virtual currencies share some important features of both fiat currencies
