It is well known from anecdotal, survey and econometric evidence that the relationship between the exchange rate and macro fundamentals is highly unstable. This could be explained when structural parameters are known and very volatile, neither of which seems plausible. Instead we argue that...

In the recent decade, capital outows from emerging economies, in the form of a demandfor liquid assets, have played a key role in the context of global imbalances. In this paper,we model the demand for liquid assets by rms in a dynamic open-economy macroeconomicmodel. We nd that the implications...

We develop a simple general equilibrium framework to study the effect of the exchange rate system on trade and welfare. An important feature of the model is deviations from purchasing power parity, caused by rigid price setting in buyers' currency. We find the following. First, exchange rate...

This paper examines the relationship between the exchange rate regime and trade flows using a general equilibrium model based on Bacchetta and van Wincoop (AER, 2000). We show that in general the link between trade and the exchange rate regime is ambiguous and that it depends in particular on...

Nominal rigidities due to menu costs have become a standard element in closed economy macroeconomic modelling. The 'New Open Economy Macroeconomics' literature has investigated the implications of nominal rigidities in an open economy context and found that the currency in which prices are set...

This paper presents a general equilibrium currency crisis model of the 'third generation', in which the possibility of currency crises is driven by the interplay between private firms' credit-constraints and nominal price rigidities. Despite our emphasis on microfoundations, the model remains...

It is well known that the extent of pass-through of exchange rate changes to consumer prices is much lower than to import prices. One explanation is local distribution costs. Here we consider an alternative, complementary, explanation based on the optimal pricing strategies of firms. We consider...

On the eve of a major change in the world monetary system, the adoption of a single currency in Europe, our theoretical understanding of the implications of the exchange rate regime for trade and capital flows is still limited. We argue that two key model ingredients are essential to address...
