We build a one-period general equilibrium model with money. Equilibrium exists, and fiat money has positive value, as long as the ratio of outside money to inside money is less than the gains to trade available at autarky. We show that the nominal effects of government fiscal and monetary policy...

We characterize equilibria with endogenous debt constraints for a general equilibrium economy with limited commitment in which the only consequence of default is losing the ability to borrow in future periods. First, we show that equilibrium debt limits must satisfy a simple condition that...

In the past few years the view has commonly been expressed that central banks follow `Taylor Rules' (as first promulgated by Henderson and McKibbin (1993)). We show that the appearance of such an interest rate rule – a ‘pseudo-Taylor rule’ – can be created by a standard macro model in...

This article develops a tractable graphical device for analyzing the stationary, stochastic overlapping generations economy. In this paper, the graphical device is applied to the theoretical study on stochastic bubbles per Weil (1987) and gives new insights into the issue.

This paper examines quantity-targeting monetary policy in a two-period economy with fiat money, endogenously incomplete markets of financial securities, backed by collateral. Non-conventional monetary policy of injecting money results in three scenarios compatible with the equilibrium...

A prominent feature of the Kiyotaki–Wright model of commodity money is multiplicity of dynamic equilibria. We show that the extent of multiplicity hinges on the frequency of search. Holding fixed the average number of meetings over time, we vary search frequency by altering the interval...

The 2008 crash has left all the established economic doctrines - equilibrium models, real business cycles, disequilibria models - in disarray. Part of the problem is due to Smith’s "veil of ignorance": individuals unknowingly pursue society’s interest and, as a result, have no clue as to the...

This paper presents a model in which (1) fiat money has strictly positive value in the unique trembling hand equilibrium. This holds as each bank note is both: (a) a witness for the existence of some agent in the economy with debt, backed by collateral, and (b) the only matter that allows the...

Zusammenfassung: Aufbauend auf der Idee des kompensierten Golddollars von Irving Fisher (1913) handelt der Beitrag von einer kapitalfundierten Euro-Gemeinschaftswährung mit Kaufkraftgarantie, dem kapitalfundierten Hart-Euro (KHE). Das Konzept beinhaltet zunächst die Funktionsweise und die...
