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....

Over the past decade the US has experienced widening current account deficits and a steady deterioration of its net foreign asset position. During the second half of the 1990s, this deterioration was fuelled by foreign investment in a booming US stock market. During the first half of the 2000s,...

Business cycles are both less volatile and more synchronized with the world cycle in rich countries than in poor ones. We develop two alternative explanations based on the idea that comparative advantage causes rich countries to specialize in industries that use new technologies operated by...

Faced with income fluctuations, countries smooth their consumption by raising savings when income is high, and vice versa. How much of these savings do countries invest at home and abroad? In other words, what are the effects of fluctuations in savings on domestic investment and the current...

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...

We develop a stylized model of economic growth with bubbles. In this model, financial frictions lead to equilibrium dispersion in the rates of return to investment. During bubbly episodes, relatively inefficient investors demand bubbles while relatively efficient investors supply them. Because...

Conventional wisdom says that, in the absence of sufficient default penalties, sovereign risk constraints credit and lowers welfare. We show that this conventional wisdom rests on one implicit assumption: that assets cannot be retraded in secondary markets. Once this assumption is relaxed, there...

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...

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...

During the last few decades, many emerging markets have lifted restrictions on cross-border financial transactions. The conventional view was that this would allow these countries to: (i) receive capital inflows from advanced countries that would finance higher investment and growth; (ii) insure...
