Both empirical evidence and theoretical discussion has long emphasized the impact of ¡¥news¡¦ on exchange rates. In most exchange rate models, the exchange rate acts as an asset price, and as such responds to news about future returns on assets. But the exchange rate also plays a role in...

This paper develops a welfare-based model of monetary policy in an open economy. We focus on the extent to which monetary policy should be employed in stabilising the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...

This paper develops a model of endogenous exchange rate pass-through within an open economy macroeconomic framework, where both pass-through and the exchange rate are simultaneously determined, and interact with one another. Pass-through is endogenous because firms choose the currency in which...

The well-known uncovered interest parity puzzle arises from the empirical regularity that, among developed country pairs, the high interest rate country tends to have high expected returns on its short term assets. At the same time, another strand of the literature has documented that high real...

The paper draws a link between the conditions for low pass-through when there are flexible prices, and local-currency pricing when there are sticky nominal prices. It shows that the condition under which pass-through is less than one-half when prices are flexible is the same as the condition...

Mundell (1973) argues that a common currency area provides benefits for its members by offering insurance against region-specific shocks. We develop a simple model to analyse the nature of risksharing benefits of a single currency area for emerging market economies, based on Mundell's...

This paper investigates the effects of exchange rate regimes and alternative monetary policy rules for an emerging market economy that is subject to a volatile external environment in the form of shocks to world interest rates, world prices and the terms of trade. Our model allows for the...

A classic argument for flexible exchange rates is that the exchange rate plays a 'shock-absorber' role in an open economy vulnerable to country-specific shocks. This paper presents a sharp counter-example to this argument within a very conventional open economy model. Countries are subject to...

Most theoretical analysis of flexible vs. fixed exchange rates take the degree of nominal rigidity to be independent of the exchange rate regime choice itself. But informal policy discussion often suggests that a credible exchange rate peg may increase internal price flexibility. This paper...

Empirical evidence from the Asian financial crisis of 1997-1998 suggests that exchange rate depreciation may have had a contractionary effect on the traded good sector of the worst-hit economies. Many writers have suggested that this was caused by exchange rate sensitive credit constraints...
