Dollarization and the Conquest of Hyperinflation in Divided Societies

Abstract

This article studies the effects of political institutions on inflation. In our view, hyperinflation is the manifestation of a tragedy of commons in a divided society with a weak central monetary authority. Economies with fiat money are inherently inflation-prone: the collection of seigniorage through the inflation tax is less conspicuous than other taxes, and the printing of money is essentially costless. In many countries, the control of the money supply is de facto or de jure decentralized. Sets of agents (in various regions or interest groups) can effectively pressure the central government to finance their expenditures. As these interest groups pursue their self-interest, they neglect the welfare effects of the inflation tax on individuals in other groups. These elements combine to imply that countries which rely on the inflation tax to meet the resource demands of competing interest groups will typically experience inefficiently (due to negative spillovers) high inflation.
