Human Capital and Ethnic Self-Identification of Migrants The paper investigates the role of human capital for migrants' ethnic ties towards their home and host countries. Pre-migration characteristics dominate ethnic self-identification. Human capital acquired in the host country does not affect the attachment to the receiving country.

We develop a model with finite number of multiproduct firms together continuum single-product and study the dynamics that arise from product innovation. Consistent available evidence, predicts rising markups concentration declining labor share. Our predict possibility an inverted-U relationship between productivity span, for which we provide suggestive evidence. In optimal allocation, span are ...

We study how search frictions in the labor market affect firms’ ability to recruit talented workers. In a field experiment Ethiopia, we show that an employer can attract more applicants by offering small monetary incentive for making job application. Estimates from structural model suggest intervention is effective because cost of application large, and positively correlated with jobseeker abil...

This paper studies the impact of immigration to United States on vote share for Republican Party using county-level data from 1990 2016. Our main contribution is show that an increase in high-skilled immigrants decreases votes, while inflow low-skilled increases it. These effects are mainly due indirect existing citizens’ and this independent origin country race immigrants. We find political ef...

We show that business cycles reduce welfare through a decrease in the average level of employment labor market search model with learning on job and skill loss during unemployment. Empirically, unemployment job-finding rate are negatively correlated. Since new jobs product these two from transition equation, imply fewer jobs. Learning implies resulting reduces aggregate human capital. This ince...

We design three field experiments to estimate how workers' social preferences toward their employer motivates work effort. vary the pay rates offered workers, return employer, and generosity demonstrated via unexpected gifts. Workers exert effort even without private incentives, but is insensitive employer. This consistent with “warm glow” not pure altruism. The gifts have no effect on producti...

The present paper contributes to the theoretical analysis of the human capital investment and participation decision of heterogeneous workers in the search and matching framework‎. ‎Its aim is to characterize the equilibrium and to identify the efficiency‎. ‎Here‎, the paper studies search equilibrium and matching to consider the participation decision of heterogeneous workers who have differen...

This paper uses administrative data from Sweden to document trends in the labor market returns skills. Between 1992 and 2013, economic return noncognitive skill—a psychologist-assessed measure of teamwork leadership skill—roughly doubled. The cognitive skill was relatively stable decreased modestly during 2000s, however. Among men with similar levels education, is higher than skill. increasing ...

We document that nearly half of the global decline in agricultural employment was driven by new cohorts entering labor market. A dataset policy reforms supports an interpretation these cohort effects as human capital. Using a model frictional reallocation, we conclude capital growth led to sharp supply, accounting, at fixed prices, for 40 percent decrease employment. This aggregate effect is ha...

This paper discusses those sources of endogenous growth arising from labor as labor. It uses a production function which models the returns to scale as a function of the division of labor and learning. Smithian analysis of the labor process constitutes the basis upon which we build our own approach. © 2001 Elsevier Science B.V. All rights reserved. JEL classification: D24; J24; O41
