This paper studies bank runs in a model with coexistence of fiat money and private money. When fiat money is the only medium of exchange, there exist a bank run equilibrium and an equilibrium that achieves the optimal risk sharing. In contrast, when private money is also a medium of exchange,...

We consider an environment where the general equilibrium assumption that every agent buys and sells simultaneously is relaxed. We show that fiat money can implement a Pareto optimal allocation only if taxes are type-specific. We then consider intermediated money by assuming that financial...

The paper identifies based on the monetary overinvestment theories by Wicksell (1898), Mises (1912) and Hayek (1929) monetary policy mistakes in large industrial countries issuing international currencies. It its argued that a neglect towards monetary policy reform in a world dominated by...

Classical models of money are typically based on a competitive market without capital or credit. They then impose exogenous timing structures, market participation constraints, or cash-in-advance constraints to make money essential. We present a simple model without credit where money arises...

Proponents of the so-called New Economy claim that it entails a structural change of the economy. Such a change, in turn, would require the central bank to rethink its monetary policy to the extent that traditional relationships between inf1ation and economic growth are no longer valid. But such...

This paper documents the recent performance of European electronic purses. It presents data on 16 such schemes, and compares their penetration and usage rates. These rates are shown to differ substantially. A number of schemes are doing increasingly well and in all probability are here to stay....

"A century of macroeconomic and monetary thought at the National Bank of Belgium" traces the history of economic research at the National Bank of Belgium, from the early decades of the 20th century to its present functioning in the Eurosystem. The study also goes into the major economic policy...

The general equilibrium model with incomplete financial markets (GEI) is extended by adding fiat money, fiscal and monetary policy and a cash-in-advance constraint. The central bank either pegs the interest rate or money supply while the fiscal authority sets a Ricardian or a non-Ricardian...

We develop a dual currency search model to study equilibrium currency exchange and the determination of nominal exchange rates. Agents hold portfolios consisting of two distinct currencies. We study equilibria in which the two currencies are identical and equilibria in which the two currencies...
