The 1990s have witnessed a revival in economists' interest and hope of explaining aggregate and microeconomic investment behavior. New theories, better econometric procedures, and more detailed panel data sets are behind this movement. Much of the progress has occurred at the level of...

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...

In this paper we present a model of fire sales and market breakdowns, and of the financial amplification mechanism that follows from them. The distinctive feature of our model is the central role played by endogenous uncertainty. As conditions deteriorate, more “banks” within the financial...

In spite of significant institutional and macroeconomic reforms over the last decade or two, capital flows to developing economies remain highly volatile. In 1996, net private capital flows to emerging markets reached US$230 billions; by 1997 these flows had been cut in half; by 1998 halved...

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 quot;insurancequot; rather than for aggregate demand reasons. In this environment, a...

Capital flows to emerging markets remain highly volatile. This has enormous economic and social costs for developing economies. Most of the proposals to reform the international financial architecture and the IMF in particular are aimed at dealing with the most extreme cases of crises - run-like...

Emerging economies are exposed to severe and sudden shortages of international financial resources. Yet domestic agents seem not to undertake enough precautions against these sudden stops. Following our previous work, we highlight in this paper the central role played by limited domestic...

Emerging economies are prone to crises triggered by external shocks. During these crises, should the central bank stabilize the currency or domestic interest rates? If the choice is outside the central bank's control, as in a currency board, are there good policy substitutes? We argue that these...

This paper explores the consequences of extremely low real interest rates in a world with integrated but heterogenous capital markets and nominal rigidities. We establish four main results: (i) Liquidity traps spread to the rest of the world through the current account, which we illustrate with...

In this paper we provide a model of the macroeconomic implications of safe asset shortages. In particular, we discuss the emergence of a deflationary safety trap equilibrium with high risk premia. It is an acute form of a liquidity trap, in which the shortage of a specific form of assets, safe...
