Skill-Biased Technical Change is one of the most prominent explanations for the rise in wage inequality in the United States over the last decades. However, the explanation is challenged for several reasons. In this paper, I propose an alternative type of technical change, where new technologies...

Job polarization the rise in employment shares of high and low skill jobs at the expense of middle skill jobs occurred in the US not just recently, but also in the late nineteenth and early twentieth centuries. We argue that in each case polarization resulted from increased automation, and...

This paper examines job polarization at the level of local labor markets in Germany over a 30-year period. The major explanation of job polarization is skill biased technological change (SBTC): new technologies are complementary to high paying jobs but substitute workers in routine manual jobs...

This paper analyses the causal effects of educational mismatch on wages, individual health and job satisfaction. As educational mismatch is subject to unobserved heterogeneity in all of these fields, different identification strategies are applied to derive causal effects. In the wage...

Over the last decades, the United States and other developed countries have experienced profound job polarization whereby employment in high-skill and low-skill occupations increased at the expense of employment in middle-skill occupations. This paper examines the wage effects of job...

Significant policy effort is devoted to stimulate the development, adoption and diffusion of environmental-friendly technology. Sceptics worry about the effects of regulation-induced environmental technology on firms competitiveness. Since innovation is a crucial productivity driver, a potential...

This paper investigates the behaviour of employers' monopsony power and workers' wages over the business cycle. Using German administrative linked employer--employee data for the years 1985--2010 and an estimation framework based on duration models, we construct a time series of the firm-level...

The long-term earnings losses of displaced workers are substantial. We investigate the role of post-displacement occupational matching in explaining the cost of job displacement. We combine German administrative data on the work history of displaced workers with information on the task content...

This paper presents an analytical setup that makes predictions for the relationships between firm and occupation specific human capital and job switches. The predictions are then tested using the task based approach. The results, based on data for Germany, show that the degree to which firm...
