This paper analyzes the career progression of skilled and unskilled workers, with a focus on how careers are affected by economic downturns, and whether formal skills, acquired early on, are able to shield workers from the effect of recessions. We estimate a dynamic life-cycle model of education choice, labor supply and wage progression using detailed administrative data for Germany for numerou...

The Persistence of Informality: Evidence from Panel Data Informality is a growing phenomenon in the developing and transition country labor market context. In particular, it is noticeable that working in an informal employment relationship is often not temporary. The degree of persistence of informality in the labor market might be due to different sources: structural state dependence due to pa...

This paper develops a dynamic model of mismatch. Workers and jobs are randomly assigned to labor markets. Each labor market clears at each instant but some have more workers than jobs, hence unemployment, and some have more jobs than workers, hence vacancies. As workers and jobs move between labor markets, some unemployed workers find vacant jobs and some employed workers lose or leave their jo...

More than two-thirds of the unauthorized immigrant population—roughly 8 million out of 11.2 million—is in our nation’s workforce, and growing evidence suggests that unauthorized workers are more likely than their authorized counterparts to experience workplace-related violations. Although scholars have begun shifting their focus to the agencies empowered to regulate immigrants in the workplace,...

This paper surveys the existing empirical research that uses search theory to empirically analyze labor supply questions in a structural framework, using data on individual labor market transitions and durations, wages, and individual characteristics. The starting points of the literature are the Mincerian earnings function, Heckman’s classic selection model, and dynamic optimization theory. We...

Based on a case study conducted at a public institution for higher education, the article investigates the dynamics of the scientific field of stem cell research. Basic research projects with adult and embryonic stem cells (experiments in cell culture or an animal model) and tissue bioengineering were surveyed. Fieldwork included ethnographic observation and interviews with researchers (graduat...

Metabolic labeling of glycans with bioorthogonal reporters has been widely used for glycan imaging and glycoproteomic profiling. One of the intrinsic limitations of metabolic glycan labeling is the lack of cell-type selectivity. The recently developed liposome-assisted bioorthogonal reporter (LABOR) strategy provides a promising means to overcome this limitation, but the mechanism of LABOR has ...

We estimate a …nite mixture dynamic programming model of schooling decisions in which the log wage regression function is set in a random coe¢ cient framework. We also analyze the determinants of 3 counterfactual experiments (a college attendance subsidy, a high school graduation subsidy and an overall decrease in the rate of time preference) and examine a proposition often claimed in the “Aver...

Background Low birth weight is one of the most important health indicators in evaluating pregnancy care worldwide. We aimed to evaluate the effect of cell phones used in pregnancy on fetal growth and preterm labor. Materials and Methods The search process included screening the rel...
