This paper reviews the extensive theoretical and empirical literature on currency substitution. After discussing the ambiguity surrounding the definition of currency substitution, the paper illustrates the causes of substitutability of different currencies using a cash-in-advance model and a...

A long standing issue in macroeconomics is that of the relation of imperfect competition to fluctuations in output. In this paper we examine the relation between monopolistic competition and the role of aggregate demand in the determination of output. We first show that monopolistically...

The performance of empirical money demand equations over the past decade raises serious questions about money demand predictability. A variety of specifications were presented to explain past episodes of apparent money demand instability, but their success in predicting future money demand is...

Previous models of the demand for money are either inconsistent with contemporaneous adjustment of the price level to expected changes in the nominal money supply or imply implausible fluctuations in interest rates in response to unexpected changes in the nominal money supply. This paper...

We develop a model in which, as in practice, bank debt is both a financial security used to raise funds and a kind of money used to facilitate trade. This dual role of bank debt provides a new rationale for why banks do what they do. In the model, banks endogenously perform the essential...

This paper reexamines the debate over whether the United States fell into a liquidity trap in the 1930s. We first review the literature on the liquidity trap focusing on Keynes's discussion of "absolute liquidity preference" and the division that soon emerged between Keynes, who believed that a...

The paper estimates a long-run demand function for M1, using U.S. data for 1959-1993. This paper interprets deviations from this long-run relation with Goldfeld's partial adjustment model. A key innovation is the choice of the interest rate in the money demand function. Most previous work uses a...

This paper examines two potential benefits that emerging economies may derive from dollarization. First, dollarization may eliminate distortions induced by the lack of credibility of monetary policy. Second, dollarization may weaken financial frictions that result in endogenous credit...

Standard explanations of the bivariate correlation of money and income attribute this correlation to an inability of agents to discriminate in the short run between real and nominal sources of price shocks. This paper is an empirical comparison of the standard explanation with two alternatives:...
