This paper is a dynamic extension of the well-known theory of trade in tasks. In my model, a firm's offshoring decision is governed by production cost savings, but also considers potential imitation risk. I show that such a consideration reduces the level of offshoring compared to a static...

This paper analyses the causal effects of educational mismatch on wages, individual health and job satisfaction. As educational mismatch is subject to unobserved heterogeneity in all of these fields, different identification strategies are applied to derive causal effects. In the wage...

Das Projekt erarbeitete eine Bestandsaufnahme und kritische Diskussion gängiger Bildungsindikatoren im internationalen Vergleich aus interdisziplinärer und bildungsökonomischer Sicht. Im Fokus standen OECD-Indikatoren zu Bildungsabschlüssen, zu Schüler- und Erwachsenenkompetenzen (PISA,...

Student performance differs greatly across countries, but little is known about the role of teacher quality in explaining these differences. New international data from the PIAAC survey of adult skills allow for the first time to quantify teacher skills in numeracy and literacy, providing...

This article reconsiders the empirical evidence on regional human capital externalities using longitudal survey data from the German Socio-Economic Panel (SOEP). It complements the empirical literature on the role of human capital for explaining regional wage differences. Based on the framework...

This paper sets up a heterogeneous firms model, where production consists of a continuum of tasks that differ in complexity. Firms hire low-skilled and high-skilled workers to perform these tasks. How firms assign workers to tasks depends on factor prices for the two skill types and the...

While there is a big literature on the benefits of pre-school education, only little is known why kindergarten attendance improves later-life outcomes. This is partly because most studies analyze the effect of complete 2 years pre-school programs. In order to shed light into the black box of...

Job polarization the rise in employment shares of high and low skill jobs at the expense of middle skill jobs occurred in the US not just recently, but also in the late nineteenth and early twentieth centuries. We argue that in each case polarization resulted from increased automation, and...

This paper estimates sibling correlations in cognitive skills and non-cognitive skills to evaluate the importance of family background for skill formation. The study is based on a large representative German dataset, which includes IQ test scores and measures of personality (locus of control,...
