The Growth of Low-Skill Service Jobs and the Polarization of the US Labor Market
We offer a unified analysis of the growth of low-skill service occupations between 1980 and 2005 and the concurrent polarization of US employment and wages. We hypothesize that polarization stems from the interaction between consumer preferences, which favor variety over specialization, and the falling cost of automating routine, codifiable job tasks. Applying a spatial equilibrium model, we co...
متن کاملSkill Biased Technical Change Polarization of the Labor Market and Wage Inequality
Shifts in the aggregate production function have long been studied by economists. Solow (1957) first classified these shifts as technical changes that can encompass slowdowns, speedups or improvements in the education of the labor force. Solow showed that these technical changes were factor-neutral from 1909-1949. Shifts in the production function are neutral if they leave the marginal rate of ...

To learn to read is to acquire a visual language skill that systematically maps onto extant spoken language skills. Some children perform this task quite adeptly, while others encounter much difficulty, and it has become a question of both scientific and practical merit to ask why there exists such a range of success in learning to read. Obviously, learning to read places a complex burden on ma...

While the need for hierarchies within control systems is apparent, it is also clear to many researchers that such hierarchies should be learned. Learning both the structure and the component behaviors is a diicult task. The beneet of learning the hierarchical structures of behaviors is that the decomposition of the control structure into smaller transportable chunks allows previously learned kn...
متن کاملSkill Inference with Personal and Skill Connections
Personal skill information on social media is at the core of many interesting applications. In this paper, we propose a factor graph based approach to automatically infer skills from personal profile incorporated with both personal and skill connections. We first extract personal connections with similar academic and business background (e.g. co-major, co-university, and co-corporation). We the...
