This paper uses an open economy DSGE model to explore how trade openness affects the transmission of domestic shocks. For some calibrations, closed and open economies appear dramatically different, reminiscent of the implications of Mundell-Fleming style models. However, we argue such stark...

Standard models of international risk sharing with complete asset markets predict a positive association between relative consumption growth and real exchange-rate depreciation across countries. The striking lack of evidence for this link the consumption/real-exchange-rate anomaly or...

We propose an exchange rate model which is a hybrid of the conventional specification with monetary fundamentals and the Evans-Lyons microstructure approach. It argues that the failure of the monetary model is principally due to private preference shocks which render the demand for money...

Relying upon a standard New Keynesian DSGE, we propose an explanation for two empirical findings in the international finance literature. First, the unbiasedness hypothesis – the proposition that expost exchange rate depreciation matches interest differentials – is rejected much more...

This paper examines optimal monetary policy in an open-economy two-country model with sticky prices. We show that currency misalignments are inefficient and lower world welfare. We find that optimal policy must target not only inflation and the output gap, but also the currency misalignment....

The paper examines the robustness of Interest Rate Rules, IRRs, in the context of an imperfectly credible stabilization program, closely following the format of much of the literature in open-economy models, e.g., Calvo and Végh (1993 and 1999). A basic result is that IRRs, like Exchange Rate...

This paper studies the role of asset-market completeness for the properties of optimal policy. A suitable framework for this purpose is the small open economy with complete international asset markets. For in this environment changes in policy represent country-specific risk diversifiable in...

This paper presents an overview of recent theoretical and empirical research on 'liquidity models' in open economies; this is a class of optimizing models where money has effects on real asset prices and economic activity without relying on the 'ad-hoc' assumption of price/wage stickiness. The...

The classical model of balance of payments crises implicitly assumes that the central bank sits passively as international reserves dwindle. In practice, however, central banks typically defend pegs aggressively by raising short-term interest rates. This paper analyzes the feasibility and...

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...
