We introduce a novel assignment model to understand patterns of firm growth and entrepreneurial (managerial) turnover. The economy is endowed with a measure of en- trepreneurs who are distinct in two dimensions: they vary in their skill e to operate a given technology and in their ability to...

From the end of the SecondWorldWar to the beginning of the Twenty-First Century, per-capita GDP in the economies of East Asia grew almost three times as fast as in the economies of Latin America. Specifically, in 1950, the economies of the Asian Tigers (Japan, South Korea, Singapore and Taiwan)...

Some regions of the United States fared much worse than others since the end of WWII. In this paper we document that those regions faring worst in terms of wage and employment growth from 1950-2000 tended to be those in which workers earned the largest wage premiums in 1950. We use this evidence...

We document large differences across OECD countries in fluctuations of the intensive and extensive margin of labor supply over the business cycle. Countries with larger fluctuations in employment relative to hours per worker tend to display larger fluctuations in total hours worked. These facts...

Through a purely positive lens, we study and document the growing trend of mortgagors who skip mortgage payments as an extra source of "informal" unemployment insurance during the 2007 recession and the subsequent recovery. In a dynamic model, we capture this behavior by treating both...

This paper studies the recent evolution of the Spanish economy in the context of the developments of the world economy and presents a benchmark model with …nancial frictions to assess the sources of these ‡uctuations. We pay particular attention to the comparison with the United States and...

This paper analyzes and computes the equilibria of economies with large numbers of heterogeneous agents who have different asset trading technologies, preferences and beliefs. We illustrate the value of our method by using it to evaluate the implications of these heterogeneities through several...

Our paper examines the impact of heterogeneous trading technologies for households on asset prices and the distribution of wealth. We distinguish between passive traders who hold fixed portfolios of stocks and bonds, and active traders who adjust their portfolios to changes in expected returns....

This paper evaluates the gains from international risk sharing in some simple general-equilibrium models with output uncertainty. Under empirically plausible calibration, the Incremental loss from a ban on international portfolio diversification is estimated to be quite small--0.15 percent of...
