چکیده
One of the most remarkable developments in the US labor market of the past two and a half decades has been the rapid, simultaneous growth of employment in both the highestand lowest-skilled jobs. This phenomenon is depicted in Figure 1, which plots changes in the share of aggregate hours worked at each percentile of the occupational skill distribution over the period 1980 through 2005. These skill percentiles are constructed by ranking occupations according to their mean hourly wages in 1980 and grouping them into 100 bins, each comprising 1 percent of 1980 employment. The pronounced U-shape of Figure 1 underscores that employment growth over this 25-year period has been disproportionate in the top and bottom of the occupational skill distribution. Occupations that were in the lowest and highest deciles of the 1980 distribution grew in relative size by 10 to 25 percent between 1980 and 2005, while occu-

The growth in wage inequality was most rapid during the 1980s, and involved a spreading out of the entire wage distribution. Rapid secular growth in the demand for skills, partly fro...
متن کاملWage Inequality in Developing Countries: An Examination of New Economic Geography Theory
The purpose of this study is to investigate the factors affecting the manufacturing industry wage among selected developing countries based on new economic geography theory. More specifically, we use a panel data model to study the spatial structure of wages in 136 countries for the period 1998-2007. The results indicate that this theory provides a good description of the spatial structure of w...
متن کاملModified Pareto archived evolution strategy for the multi-skill project scheduling problem with generalized precedence relations
In this research, we study the multi-skill resource-constrained project scheduling problem, where there are generalized precedence relations between project activities. Workforces are able to perform one or several skills, and their efficiency improves by repeating their skills. For this problem, a mathematical formulation has been proposed that aims to optimize project completion time, reworki...
متن کاملWage and Job Dynamics after Welfare Reform: the Importance of Job Skills
