In this paper I demonstrate, both theoretically and empirically, that the interpretation of regression estimates of between-group differences in economic outcomes depends on the relative sizes of subpopulations under study. When the disadvantaged group is small, regression estimates are similar...

While the informal sector has received widespread attention in academic and policy arenas in recent decades, knowledge gaps and controversies remain. By examining the incidence and determinants of the formal-informal sector earnings gap for adult male dependent employees using two identical,...

While the informal sector has received widespread attention in academic and policy arenas in recent decades, knowledge gaps and controversies remain. First, while the evidence is starting to emerge, there is still more to learn about the formal-informal sector earnings gap of the former...

Human capital models imply that both the distribution of education and returns to education affect earnings inequality. Decomposition of these 'quantity' and 'price' components have been important in understanding changes in earnings inequality in developed and developing countries. This paper...

We analyse full-time monthly wages of employees with parents born in Sweden and of childhood immigrants who arrived before the end of compulsory school-age. We use a detailed disaggregation of background countries, which shows considerable heterogeneity, in overeducation, in returns to education...

We analyse wage differentials between Higher Education graduates in the UK, differentiating between polytechnic and university graduates. Polytechnic graduates earned on average lower wages than university graduates prior to the UK Further and Higher Education Act of 1992. The reform changed the...

In elementary school, girls typically outperform boys in languages and boys typically outperform girls in math. The determinants of these differences have remained largely unexplored. Using rich data from Dutch elementary schools, we decompose the differences in achievement into gender...

SBTC is a powerful mechanism in explaining the increasing gap between educated and uneducated wages. However, SBTC cannot mimic the US within-group wage inequality. This paper provides an explanation for the observed intra-college group inequality by showing that the top decile earners’...
