In this paper we produce a theory of partial default applicable to sovereign debt. The theory uses Markovian equilibria and the notion that circulating unpaid coupons of any given country courtail its productive capabilities. As a consequence no issues of equilibrium selection appear in the...

We argue that the large and growing North-South trade imbalances arisen over the last three decades may have exacerbated wage inequality worldwide. In particular, we show that in a standard Heckscher-Ohlin setup with a continuum of goods, a Southern trade surplus is associated with higher skill...

The rate of long-term unemployment spiked during the Great Recession. To help explain this, I exploit the systematic and counter-cyclical differences in unemployment duration across occupations. This heterogeneity extends the tail of the unemployment duration distribution, which is necessary to...

Data on the world saving distribution reveals three key features: (i) saving rates are significantly different across countries and they remain different for long periods of time; (ii) the average saving rate has remained relatively unchanged but the dispersion in saving rates has risen; and...

This paper examines the relationship between sovereign bond spreads, local economic activity, and global financial risk. We use secondary-market prices of dollar-denominated sovereign securities to construct yield spreads between sovereign bond yields and yields on the appropriately defined...

We built a unique dataset of 300,000 famous people born between Hammurabi's epoch and 1879, Einstein's birth year. It includes, among other variables, the vital dates, occupations, and locations of celebrities from the Index Bio-bibliographicus Notorum Hominum (IBN), a very comprehensive...

I study a principal-agent problem in which the principal can obtain additional costly information about the agent's effort. I analyze this problem in the context of optimal unemployment insurance a la Hopenhayn and Nicolini (1997), where job-search effort is private information. I calibrate the...

We develop an heterogeneous agent model of consumption and health choices in order to estimate the effect of heath status in the marginal utility of consumption. We use micro data from the HRS, PSID, and CEX to identify the parameters of interest from the observed consumption growth for...

When trade is costly within countries, international trade leads to concentration of economic activity in locations with good access to foreign markets. Costly trade within countries also makes it hard for remote locations to gain from international trade. We investigate the role of these forces...
