Global risk-off shocks can be highly destabilizing for financial markets and, absent an adequate policy response, may trigger severe recessions. Policy responses were more complex for developed economies with very low interest rates after the Global Financial Crisis (GFC). We document, however,...

Emerging economies experience sudden stops in capital inflows. As we have argued in Caballero and Krishnamurthy (2002), having access to monetary policy during these sudden stops is useful, but mostly for insurance' rather than for aggregate demand reasons. In this environment, a central bank...

One of the main economic villains before the crisis was the presence of large "global imbalances." The concern was that the U.S. would experience a sudden stop of capital flows, which would unavoidably drag the world economy into a deep recession. However, when the crisis finally did come, the...

The U.S. is currently engulfed in the most severe financial crisis since the Great Depression. A key structural factor behind this crisis is the large demand for riskless assets from the rest of the world. In this paper we present a model to show how such demand not only triggered a sharp rise...

In this paper we argue that the persistent global imbalances, the subprime crisis, and the volatile oil and asset prices that followed it, are tightly interconnected. They all stem from a global environment where sound and liquid financial assets are in scarce supply

The world has a shortage of financial assets. Asset supply is having a hard time keeping up with the global demand for store of value and collateral by households, corporations, governments, insurance companies, and financial intermediaries more broadly. The equilibrium response of asset prices...

One of the most serious problems that a central bank in an emerging market economy can face, is the sudden reversal of capital inflows. Hoarding international reserves can be used to smooth the impact of such reversals, but these reserves are seldom sufficient and always expensive to hold. In...

Three of the most important recent facts in global macroeconomics -- the sustained rise in the US current account deficit, the stubborn decline in long run real rates, and the rise in the share of US assets in global portfolio -- appear as anomalies from the perspective of conventional wisdom...
