There has been a remarkable increase in wage inequality in the US, UK and many other countries over the past three decades. A significant part of this appears to be within observable groups (such as age-gender-skill cells). A generally untested implication of many theories rationalizing the...

In this paper we argue that government spending played a significant role in stimulating the wave of innovation that hit the U.S. economy in the late 1970s and in the 1980s, as well as the simultaneous increase in inequality and in education attainment. Since the late 1970’s U.S. policy makers...

In this paper we argue that government procurement policy played a role in stimulating the wave of innovation that hit the US economy in the 1980s, as well as the simultaneous increase in inequality and in education attainment. Since the early 1980s U.S. policy makers began targeting commercial...

We contribute to the debate on skill-biased technical change by studying the long-run dynamics of skill premia in an endogenous growth model in which technical change can be directed alternately towards different factors. We show that R&D resources tend to be directed alternately towards...

We examine the relationship between research and development (R&D) intensity and wages, using a unique matched employer-employee dataset. The dataset has the advantage that it links firm-level investment in R&D to individual employee wages and allows us to control for both employee and employer...

We examine the relationship between performance pay systems and wages, paying particular attention to gender differences in outcomes. At the firm level, estimates suggest average wages are unaffected by changes in performance pay practices, but that the within-firm distribution of wages is...

This paper studies how changes in the complexity of the firms' production technologies affect wage differences between and within tasks. In a production process where tasks are complementary, the employer may have an incentive to pay higher wages when using more complex technologies because the...

Did nineteenth century technology reduce demand for skilled workers in contrast to modern technology? I obtain direct evidence on human capital investments and the returns to skill by using micro-data on individual weavers and an engineering production function. Weavers learned substantially on...

This study provides strong evidence for an increase in wage inequality induced by skillbiased technological change in the UK manufacturing industry between 1991 and 2006. Using individual level data from the BHPS and industry level data from the OECD, wage regressions are estimated which...
