This paper analyzes the sustainability of fixed exchange rates by extending the Barro-Gordon framework to a fully dynamic context in which the level of a state variable (in this case debt) determines the payoffs available to the government at each point in time. The model yields the following...

The paper reviews the recent literature on exchange rate target zones and on speculative attacks on fixed exchange rates. The influential Krugman model of exchange rate target zones has two main results, namely that credible target zones stabilize exchange rates more than fundamentals (the...

A developing country often pegs its exchange rate to a single currency, such as the U.S. dollar, even though it faces a higher inflation rate than the country to which it is pegged. As a consequence, it experiences real exchange-rate misalignments and a series of easily-anticipated devaluations....

Economists generally assert that countries sacrifice monetary independence when they peg their exchange rates. At the same time, central bankers frequently assert that pegging an exchange rate does not eliminate the independence of monetary policy. This paper examines the effects of money-supply...

The paper argues that the reason real world fixed exchange rate regimes usually have finite bands instead of completely fixed exchange rates between realignments is that exchange rate bands, counter to the textbook result, give central banks some monetary independence, even with free...

We use time-series methods to estimate a simple aggregate-supply aggregate-demand model in order to analyze the comparative performance of fixed- and flexible-exchange-rate systems and test competing hypotheses designed to explain shifts between exchange-rate regimes. The paper provides a...

The purpose of this paper is to determine whether a two-tier exchange rate regime is more effective than a fixed rate regime in increasing acountry's ability to pursue an independent monetary policy in the short run.The analysis compares adjustment to a monetary policy and to a devaluation in...

A country that decides to fix its exchange rate thereby gives up control over its own inflation rate and the determination of the revenue received from seigniorage. If the country goes further and uses a foreign money, it loses all seigniorage. This paper uses an optimal inflation tax approach...

This paper presents a long-run model of the open economy in a world of fixed exchange rates and imperfect substitutability between bonds denominated in different currencies. The model explicitly accounts for the wealth flow accompanying current-account imbalance and for the flow of interest...

This paper explores the relationship between exchange rate adjustment and trade policy in a simple New Keynesian open economy macro model. We show that movement in exchange rates have a direct implication for trade policy when governments choose tariffs endogenously. In particular, we show that...
