This dissertation consists of four distinct empirical essays that address various aspects of the economics of education. Chapters 2 and 3 show that patience and risk-taking as intertemporal preferences are closely related to differences in student achievement across and within countries. Chapter...

This paper examines the changing nature of occupational labour-market trends in South Africa and the resulting impact on wages. We observe high levels of demand for skilled labour that have intensified a trend already established before 1994. Over the period 2001-12 employment within the primary...

Technical change impacts both the employment intensity of production and the composition of occupations and skills of employment. Artificial intelligence, automation, and robots are already leading to machines undertaking routinizable tasks previously carried out by workers. This can lead to...

Success in life increasingly depends on key skills that allow people to thrive in education, the labor market, and their interactions with others. In this paper, we emphasize creativity as a key skill that is essential to open-ended problem solving and resistant to automation. We use rich...

This article investigates the extent to which personality traits and cognitive skills can be seen as potential determinants of overeducation, and can explain the overeducation wage penalty. Using a representative survey of the Polish working-age population with well-established measures of...

Using a promotion signaling model in which wages are realistically shaped by market forces, we analyze how male overconfidence combined with competitive workplace incentives affects gender equality in the labor market. Our main result is that overconfident workers exert more effort to be...

Gender differences in overconfidence have been extensively documented in the empirical literature, but the implications for labor market outcomes are not well understood. In this paper, we analyze how men's relatively higher overconfidence, combined with competitive job incentives, affects...

We merge experimental data on competitiveness of a large sample of students with their complete educational history for up to ten years after the initial assessment. Exploiting quasi-random class assignments, we find that having competitive peers as classmates makes students choose and secure...

A model is presented where workers of differing abilities and from different social backgrounds are assigned to jobs based on grades received at school. It is examined how this matching is affected if good grades are granted to some low ability students. Such grade inflation is shown to reduce...
