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...

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...

We study the determinants of comparative advantage in polluting industries. We combine data on environmental policy at the country level with data on pollution intensity at the industry level to show that countries with laxer environmental regulation have a comparative advantage in polluting...

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,...

We argue that emerging economies borrow short term due to the high risk premium charged by bondholders on long-term debt. First, we present a model where the debt maturity structure is the outcome of a risk sharing problem between the government and bondholders. By issuing long-term debt, the...

There is a large and growing literature that studies the effects of weak enforcement institutions on economic performance. This literature has focused almost exclusively on primary markets, in which assets are issued and traded to improve the allocation of investment and consumption. The general...

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...

The first generation models of currency crises have often been criticized because they predict that, in the absence of very large triggering shocks, currency attacks should be predictable and lead to small devaluations. This paper shows that these features of first generation models are not...

This paper analyzes the joint behavior of international capital flows by foreign and domestic agents--gross capital flows--over the business cycle and during financial crises. We show that gross capital flows are very large and volatile, especially relative to net capital flows. When foreigners...
