A transactions model of the demand for multiple media of exchange is developed and applied to the study of currency substitution. The analysis provides a theoretical foundation for results reported in the empirical literature. Some results are expected, such as the dependence of currency...

Unlike most hyperinflations, during Zimbabwe's recent hyperinflation, as in Revolutionary France, the currency ended before the regime. The empirical results here suggest that the Reserve Bank of Zimbabwe operated on the correct side of the inflation tax Laffer curve before abandoning the...

The delayed end to Zimbabwe's hyperinflation in 2009 gave rise to an official dollarization. Before then, the Reserve Bank of Zimbabwe (RBZ) operated on the correct side of the inflation tax Laffer curve. Estimated seignorage maximizing rates derive from Bayesian, time-varying parameter,...

A transactions model of the demand for multiple media of exchange is developed. Some results are expected, and others are both new and surprising. There are both extensive and intensive margins to currency substitution, and inflation may affect the two margins differently, leading to subtle...

We examine money demand in the Chinese economy during a period characterized by significant disinflation and outright deflation, coupled with strong output growth. Our study establishes a stable money demand system for broad money M2. Inflation affects the adjustment of the system towards...

We examine the responses of prices and inflation to monetary shocks in an inventory-theoretic model of money demand. We show that the price level responds sluggishly to an exogenous increase in the money stock because the dynamics of households' money inventories leads to a partially offsetting...

The previous literature on dollarization processes has two basic problems. First is the poor empirical methods of measurement, and second is the lack of a clear definition of the phenomenon under study. Several methodological problems have not been successfully addressed. Foreign currency...
