We provide a theory of the limits to monetary policy independence in open economies arising from the interaction between capital flows and domestic collateral constraints. The key feature of our theory is the existence of an 'Expansionary Lower Bound' (ELB), defined as an interest rate threshold...

We develop a dynamic stochastic general equilibrium model with financial frictions on both financial intermediaries and goods-producing firms. In this context, due to high leverage of financial intermediaries, balance sheet disruptions in the financial sector are particularly detrimental for...

We use the rise and dispersion of sovereign spreads to tell the story of the emergence and escalation of financial tensions within the eurozone. This process evolved through three stages. Following the onset of the Subprime crisis in July 2007, spreads rose but mainly due to common global...

In this paper we assess the implications of precautionary savings for global imbalances by considering a world economy model composed by the US, the Euro Area, Japan, China, oil-exporting countries, and the rest of the world. These areas are assumed to differ only with respect to GDP volatility...

A reduction in the U.S. current account deficit vis-à-vis emerging Asia involves a shift in demand from U.S. to emerging Asia tradable goods and a change in international relative prices. This paper quantifies the required adjustment in the terms of trade and real exchange rates in a...

This paper shows that the behavior of entrepreneurs facing incomplete financial markets and risky investment can explain why growth accelerations in developing countries tend to be associated with current account improvements. The uninsurable risk of losing invested capital forces entrepreneurs...

Abstract I consider a small open economy model where international financial markets are imperfect and the exchange rate is determined by capital flows. I use this framework to study the effects of portfolio flow shocks, derive the optimal foreign exchange intervention policy, and...
