In this paper, we take a systematic look at global imbalances. First, we provide a definition of the phenomenon, and relate global imbalances to widening external positions of systemically important economies that reflect distortions or entail risks for the global economy. Second, we provide an...

The curse of dimensionality, a problem associated with analyzing the interaction of a relatively large number of endogenous macroeconomic variables, is a prevailing issue in the open economy macro literature. The most common practise to mitigate this problem is to apply the so-called Small Open...

One common, simplifying assumption in open economy macroliterature is that the rest of the world can be thought of as a representative economy. This article formally investigates conditions under which this assumption can be justified using a multicountry general equilibrium model as a...
