This Paper presents a stylized model of international trade and asset price bubbles. Its central insight is that bubbles tend to appear and expand in countries where productivity is low relative to the rest of the world. These bubbles absorb local savings, eliminating inefficient investments and...

How do countries hold their financial wealth? We construct a new database of countries' claims on capital located at home and abroad, and international borrowing and lending, covering 68 countries from 1966-97. We find that a small amount of capital flows from rich countries to poor countries....

We live in a new world economy characterized by financial globalization and historically low interest rates. This environment is conducive to countries experiencing credit bubbles that have large macroeconomic effects at home and are quickly propagated abroad. In previous work, we built on the...

Over the last two decades U.S. aggregate wealth has fluctuated substantially. Against the backdrop of the Great Recession, the effects of these boom-and-bust cycles have come to dominate academic and policy discussions. How can we explain these fluctuations in wealth? Why are these fluctuations...

We study a dynamic economy where credit is limited by insufficient collateral and, as a result, investment and output are too low. In this environment, changes in investor sentiment or market expectations can give rise to credit bubbles, that is, expansions in credit that are backed not by...

In 2007, countries in the euro periphery were enjoying stable growth, low deficits, and low spreads. Then the Financial crisis erupted and pushed them into deep recessions, raising their deficits and debt levels. By 2010, they were facing severe debt problems. Spreads increased and,...

As a result of debt enforcement problems, many high-productivity firms in emerging economies are unable to pledge enough future profits to their creditors and this constrains the financing they can raise. Many have argued that, by relaxing these credit constraints, reforms that strengthen...

This paper presents a theoretical study of the effects of globalization on risk sharing and welfare. We model globalization as a gradual and exogenous increase in the fraction of goods that are tradable. In the absence of frictions, globalization opens new goods markets and raises welfare. We...

It is well known that business cycles in OECD countries exhibit a remarkable degree of synchronization. Much less known is that the peak of the OECD cycle is associated with high prices of labour-intensive products and low prices of capital-intensive ones. We document this cyclical behaviour of...

The current accounts data of industrial countries exhibits some strong patterns that are inconsistent with the intertemporal approach to the current account. This is the basic model that international economists have been using for more than two decades to think about current account issues....
