This paper studies an analytically tractable model of the formation and evolution of chains of production. Over time, entrepreneurs accumulate techniques to produce their good using goods produced by other entrepreneurs and labor as inputs. The value of a technique depends on both the...

This paper investigates both aggregate and distributional impacts of the trade integration of China, India, and Central and Eastern Europe in a quantitative multi-country multi-sector model, comparing outcomes with and without factor market frictions. Under perfect within-country factor...

From 1978 to 2000 the fraction of adult men in full-year non-employment increased from 17.1 to 21.6 percent. Previous research focused on the role of disability insurance policy and wage structure changes to explain this increase. Using Current Population Surveys from 1979 to 2003 we assess how...

This paper evaluates the short-run effects of introducing labor market flexibility to an economy characterized by large firing taxes. Different reforms are considered: 1) eliminating all firing taxes, 2) introducing flexible new contracts while retaining the firing taxes on workers employed...

In this paper I evaluate to what extent a real business cycle (RBC) model that incorporates search and leisure decisions can simultaneously account for the observed behavior of employment, unemployment and out-of-the-labor-force. This contrasts with the previous RBC literature, which analyzed...

This paper extends Hopenhayn and Rogerson's analysis of firing taxes by introducing a flexible form of capital and considering transitionary dynamics. The paper finds that capital is not important for understanding the long run and welfare effects of firing taxes. However, capital is crucial for...

The self-employed are a heterogeneous group. Some are self-employed because they are good at it, while others are self-employed because they cannot find a better paying salaried job. Data from the CPS for prime age males show that workers are almost twice as likely to enter self-employment from...

We study portfolio choice when labor income and dividends are cointegrated. Economically plausible calibrations suggest young investors should take substantial short positions in the stock market. Because of cointegration the young agent's human capital effectively becomes.

This study investigates whether Hispanic immigrants assimilate in occupational status with natives and the factors that determine occupational status. A theoretical framework is proposed that models occupational status and convergence of Hispanics relative to U.S.-born non-Hispanics as a...
