This paper estimates the elasticity of substitution between capital and skill using variation across U.S. counties in immigration-induced skill-mix changes between 1860 and 1930. We find that capital began as a q-complement for skilled and unskilled workers, and then dramatically increased its...

Skills are an important predictor of labour, education, and wellbeing outcomes. Understanding the origins of skills formation is important for reducing future inequalities. This paper analyses the effect of shocks in-utero on human capital outcomes in childhood and adolescence in India....

Following the adoption of information and communication technologies (ICT), firms are likely to face increasing skill requirements. They may react either by training or hiring the new skills, or by a combination of both. We first show that ICT are indeed skill biased and we then assess the...

Different empirical studies suggest that the structure of employment in the U.S. and Great Britain tends to polarise into "good" and "bad" jobs. We provide updated evidence that polarisation also occurred in Germany since the mid-1980s until 2008. Using representative panel data, we show that...

In contrast to the very large literature on skill-biased technical change among workers, there is hardly any work on the importance of skills for the entrepreneurs who employ those workers, and in particular on their evolution over time. This paper proposes a simple theory of skill-biased change...

We provide empirical evidence on the impact of IT diffusion on the stability of employment relationships. We document the evolution of different components of job instability over a panel of 348 local labor markets in France, from the mid-1970s to the early 2000s. Although workers in more...

Over the past two decades, technological progress has been biased towards making skilled labor more productive. What does skill-biased technological change imply for business cycles? To answer this question, we construct a quarterly series for the skill premium from the CPS and use it to...

This paper investigates the changes in the German wage structure for full-time working males from 1999 to 2006. Our analysis builds on the task-based approach introduced by Autor et al. (2003), as implemented by Spitz-Oener (2006) for Germany, and also accounts for job complexity. We perform a...

The shift away from manual and routine cognitive work, and towards non-routine cognitive work is a key feature of labor markets. There is no evidence, however, if the relative importance of various tasks differs between workers performing seemingly similar jobs in different countries. We develop...

The authors provide first evidence on whether the direct relationship between educational mismatch and firm productivity varies across working environments. Using detailed Belgian linked employer-employee panel data for 1999-2010, they find the existence of a significant, positive (negative)...
