I provide a framework for understanding debt deleveraging in a group of _nancially integrated countries. During an episode of international deleveraging world consumption demand is depressed and the world interest rate is low, reecting a high propensity to save. If exchange rates are allowed to...

The `quantity anomalies' that arise from standard international business cycle models are cross-country correlations in consumption being higher than output, and negative comovement in aggregate investment and employment. This paper shows thatincorporating multiple sectors with heterogeneous...

The consensus about the ability of the standard open-economy neoclassical growthmodel to account for interest-rate driven business cycles has changed over time:whereas early research concluded that business cycles are neutral to interest-rateshocks, more recent investigations suggest that these...

During the last two decades, the degree of openness of national financial systems has increased substantially. At the same time, asymmetries in information and other financial market frictions have remain prevalent. We study both empirically and theoretically the implications of the opening up...

Credit constraints that link a private agent’s debt to market-determined prices embody a credit externality that drives a wedge between competitive and constrained socially optimal equilibria, inducing private agents to overborrow. The externality arises because agents fail to internalize the...

A two sector small open economy model developed by Corden (1991, 2002) is used to analyse the impact of sudden stops in capital inflows on an internal and external equilibrium and to explore the merits of disposing of the nominal exchange rate as policy tool in rectifying real exchange rate...

We show that a flex-price two-sector open economy DSGE model can explain the poor degree of international risk sharing and exchange rate disconnect. We use a suite of model evaluation measures and examine the role of (i) traded and non-traded sectors; (ii) financial market incompleteness; (iii)...

Credit constraints that link a private agent's debt to market-determined prices create a systemic credit externality that drives a wedge between competitive and (constrained) socially optimal equilibria, which induces private agents to "overborrow". We quantify the effects of this externality in...

Financial globalization had a rocky start in emerging economies hit by Sudden Stops. Foreign reserves have grown very rapidly since then, as if those countries were practicing a New Mercantilism that views foreign reserves as a war-chest for defense against Sudden Stops. This paper conducts a...

We develop a simple and intuitive approach for analytically deriving unconditionally optimal (UO) policies, a topic of enduring interest in optimal monetary policy analysis. The approach can be employed to both general linear-quadratic problems and to the underlying non-linear environments. We...
