We study the effects of mobility costs in a model of wage bargaining between heterogeneous workers and firms, where there is instantaneous matching, free firm entry, and workers' individual productivities are discovered by firms only after being hired.We derive the employment level and the minimum quality standard, in the market solution and in the socially efficient solution. We show that the ...

Since 1975, an increase in the return to years of schooling, in the percentage of the labor force that is skilled, and in the variance of wage income within skill categories have characterized the U.S. labor market. While the first two facts point towards an increase in the demand for skilled labor, the third fact establishes that this increase in demand has not been uniform for all members of ...

OBJECTIVE This study was undertaken to quantitatively summarize previous literature on the effects of epidural analgesia in labor on the duration of labor and mode of delivery. STUDY DESIGN Original studies published in English from 1965 through December 1997 were reviewed and assigned a quality score independently by 2 of the authors. Studies that met the minimal requirements were evaluated ...

Conditional cash transfer programs have spread to over 80 countries in the past two decades, but little is known about their long-term effects on the youth they target. This paper estimates the impact of childhood exposure to the Mexican program Progresa on economic outcomes in early adulthood by leveraging the age structure of program benefits and geographic variation in early program penetrat...

Consider an economy in which various types of labor are used to produce consumption, but not all types of labor are useful for upgrading the stock of organization capital—that is, for replacing old projects with more productive new projects. When news induces consumers to want to save more, low-quality projects are destroyed across all sectors of the economy, even though the economy is set to i...

In this study, we investigate whether ethnic discrimination depends on labor market tightness. While ranking models predict a negative relationship, the prediction of screening models is ambiguous about the direction of the relationship. Thus, the direction of the relationship is purely an empirical issue. We utilize three (but combine into two) correspondence studies of the Swedish labor marke...

This paper shows that the development from an agricultural regime through industrialization to a manufacturing regime occurs simultaneously to the demographic transition and the change in labor structure towards an increasing fraction of skilled labor due to technological progress. The manufacturing sector is economically viable when the technological level is sufficiently high. During the indu...

The 2007-2009 recession has witnessed two phenomena that standard search models of the labor market have difficulty reconciling: a large and persistent increase in unemployment and a sharp rise, above pre-recession levels, in labor productivity following a small initial drop. In addition, these observations were accompanied by a significant increase in the dispersion of firm growth rates. In th...

This paper studies the conditions under which the scarcity of a factor (in particular, labor) encourages technological progress and technology adoption. In standard endogenous growth models, which feature a strong scale e¤ect, an increase in the supply of labor encourages technological progress. In contrast, the famous Habakkuk hypothesis in economic history claims that technological progress w...
