Two macroeconomic constraints determine the credibility of an exchange rate system: the availability of foreign exchange and the sustainability of fiscal balance. The following paper analyses the relative importance of these constraints for fixed and flexible exchange rate systems, examines the...

This paper investigates the consequences of fiscal policies for the exchange rate. After developing a simple theory of how government financing policies should effect the exchange rate, we test it using data on the dollar/pound exchange rate. Previous analyses have concentrated mainly on the...

This paper studies the cross-country variation of the fiscal stimulus and the exchange rate adjustment propagated by the global crisis of 2008-9, identifying the role of economic structure in accounting for the heterogeneity of response. We find that greater de facto fiscal space prior to the...

This paper examines policy responses to exchange-rate movements in a simple model of an open economy. The optimal response of monetary policy to an exchange-rate change depends on the source of the change: on whether the underlying shock is a shift in capital flows, manufactured exports, or...

In recent years the conventional wisdom has held that fixed rates provide more fiscal discipline than do flexible rates. In this paper we show that this wisdom need not hold in a standard model in which fiscal policy is endogenously determined by a maximizing fiscal authority. The claim that...

The combination of a fixed exchange rate and downward nominal wage rigidity creates a real rigidity. In turn, this real rigidity makes the economy prone to involuntary unemployment during external crises. This paper presents a graphical analysis of alternative policy strategies aimed at...
