This empirical paper documents the relationship between composition of a firm's workforce (with a special focus on age and gender) and its performance (productivity and profitability) for a large representative sample of enterprises from manufacturing industries in Germany. We use unique newly...

This paper investigates whether on-the-job training has an effect on the employability of workers. Using data from the Netherlands we disentangle the true effect of training incidence from the spurious one determined by unobserved individual heterogeneity. We also take into account that there...

This study integrates findings from neurobiology and psychology on early childhood development and self-regulation to assess returns to education. Our framework for evaluating the distribution of age-specific returns to investments in cognitive and noncognitive skills is a lifecycle simulation...

In this paper, human capital investments are evaluated by assuming heterogeneous returns to schooling. We use the potential outcome approach to measure the causal effect of human capital investments on earnings as a continuous treatment effect. Empirical evidence is based on a sample of West...

The COVID-19 pandemic caused widespread disruptions to education, with school closures affecting over one billion children. These closures, aimed at reducing virus transmission, resulted in significant learning losses, particularly in mathematics and science. Using data from TIMSS 2023, which...

For a large set of countries, we document how the labor earnings inequality varies with GDP per capita. As countries get richer, the mean-to-median ratio and the Gini coefficient decline. Yet, this decline masks divergent patterns: while inequality at the top of the earnings distribution falls,...

Chapter 6 from the forthcoming Inclusive Wealth Report 2022 looks at human capital in greater detail, based on the latest human capital estimates from the Inclusive Wealth Report (IWR) project. In the chapter, which is repeated here, the growth of human capital and several of its constituent...

The empirical literature on employer learning assumes that employers learn about unobserved ability differences across workers as they spend time in the labor market. This article describes testable implications that arise from this basic hypothesis and how they have been used to quantify the...
