Are alternative currencies a substitute or a complement to fiat money? Evidence from cross-country data

This paper studies the determinants of the usage of alternative currencies (currencies which exists parallel to the national currency of a country) across countries. We find that monetary stability, financial sector development and a country’s general level of economic development are all positively related to both the likelihood of a country hosting an alternative currency as well to the number of alternative currencies a country is hosting. This suggests that these currencies, in contrast to their historical function, mainly act as a complement to fiat money. We discuss the implications for the role of fiat money in the economy as well as for the welfare effects of alternative currencies.
