The wages of part-time workers are considerably lower than are those of full-time workers. Measurable worker and job characteristics, including occupational skill requirements, account for much of the part-time penalty. Longitudinal analysis indicates that much of the remaining gap reflects...

A large fraction of the variation in wage levels and wage growth rates among individuals remains unexplained. Economists argue that ?unobserved? heterogeneity is among the more likely reasons for this unexplained variation in wages. The source of individual heterogeneity is typically attributed...

Part-time employment has become an extremely popular work arrangement in the Netherlands because it renders employment compatible with non-work activities. We posit that there may be a downside to part-time employment, which is related to its negative effects on workers? career. This may be the...

We address the impact of education upon wage inequality by drawing on evidence from fifteen European countries, during a period ranging between 1980 and 1995. We focus on within-educational-levels wage inequality by estimating quantile regressions of Mincer equations and analysing the...

American business seems to be infatuated with its workers? ?leadership? skills. Is there such a thing, and is it rewarded in labor markets? Using the Project Talent, NLS72 and High School and Beyond datasets, we show that men who occupied leadership positions in high school earn more as adults,...

The HIV epidemic has dramatically decreased labor supply among prime-age adults in sub-Saharan Africa. Using within-country variation in regional HIV prevalence and a synthetic panel, I find that HIV significantly increases the capital-labor ratio in urban manufacturing firms. The impact of HIV...

The paper analyzes the effect of human-capital investments of heterogeneous individuals on the dynamics of the wage structure within a neoclassical growth model. The accumulation of physical capital changes relative factor prices and thus incentives to acquire skills, thereby altering the...

We use a quantile regression framework to investigate the degree to which work-related training affects the location, scale and shape of the conditional wage distribution. Human capital theory suggests that the percentage returns to training investments will be the same across the conditional...

Using Finnish panel data, we study how entrepreneurs differ from workers in education and income dynamics. We find that workers have higher median income in all educational groups. Without additional controls, entrepreneurs have higher average income with all but undergraduate level of...

In this study we argue that wage inequality and occupational mobility are intimately related. We are motivated by our empirical findings that human capital is occupation-specific and that the fraction of workers switching occupations in the United States was as high as 16% a year in the early...
