Returns to Skills around the World: Evidence from PIAAC

Abstract
Existing estimates of the labor-market returns to human capital give a distorted picture of the role of skills across different economies. International comparisons of earnings analyses rely almost exclusively on school attainment measures of human capital, and evidence incorporating direct measures of cognitive skills is mostly restricted to early-career workers in the United States. Analysis of the new PIAAC survey of adult skills over the full lifecycle in 23 countries shows that the focus on early-career earnings leads to underestimating the lifetime returns to skills by about one quarter. On average, a one-standard-deviation increase in numeracy skills is associated with an 18 percent wage increase among prime-age workers. But this masks considerable heterogeneity across countries. Eight countries, including all Nordic countries, have returns between 12 and 15 percent, while six are above 21 percent with the largest return being 28 percent in the United States. Estimates are remarkably robust to different earnings and skill measures, additional controls, and various subgroups. Instrumental-variable models that use skill variation stemming from school attainment, parental education, or compulsory-schooling laws provide even higher estimates. Intriguingly, returns to skills are systematically lower in countries with higher union density, stricter employment protection, and larger public-sector shares.

Kommentar: Betriebsgrößenstruktur und Arbeitsmarktergebnisse
Steffen Müller
Wirtschaft im Wandel,
No. 5,
2014
Abstract
Trotz aller Fortschritte bei der wirtschaftlichen Angleichung Ost- und Westdeutschlands seit der Vereinigung wird in der öffentlichen Debatte häufig auf fortbestehende Unterschiede bei Löhnen und Arbeitsproduktivität verwiesen. Als Erklärung hierfür wird der vergleichsweise geringe Anteil großer und damit in der Regel auch produktiverer und besser zahlender Betriebe in Ostdeutschland angeführt. Die Größe eines Betriebes ist jedoch – von möglichen Skalenerträgen einmal abgesehen – für sich genommen kein Bestimmungsfaktor für ökonomische Prosperität. Für das Verständnis der Folgen einer kleinteilig organisierten Wirtschaft muss geklärt werden, über welche Mechanismen die Betriebsgrößenstruktur auf Löhne und Arbeitsproduktivität wirkt.

Do Better Pre-migration Skills Accelerate Immigrants' Wage Assimilation?

Labour Economics,
2014
Abstract
This paper analyzes wage assimilation of ethnic German immigrants to Germany using unique administrative data that include an administrative estimate of immigrants' expected wage in Germany at the time of migration. We find that a 10% higher wage potential translates into a 1.6% higher wage in Germany when also controlling for educational attainment, thus pointing at partial transferability of pre-migration skills to the host country's labor market. We also document that wage assimilation is significantly accelerated for immigrants with higher wage potentials. Our results are both in line with complementarities between pre-migration skills and host country-specific human capital and a U-shaped pattern of immigrants' job mobility with initial downgrading and subsequent upgrading.

Socially Gainful Gender Quotas
Walter Hyll, Oded Stark
Journal of Economic Behavior and Organization,
No. 105,
2014
Abstract
We study the impact of gender quotas on the acquisition of human capital. We assume that individuals’ formation of human capital is influenced by the prospect of landing high-pay top positions, and that these positions are regulated by gender-specific quotas. In the absence of quotas, women consider their chances of getting top positions to be lower than men’s. The lure of top positions induces even men of relatively low ability to engage in human capital formation, whereas women of relatively high ability do not expect to get top positions and do not therefore engage in human capital formation. Gender quotas discourage men who are less efficient in forming human capital, and encourage women who are more efficient in forming human capital. We provide a condition under which the net result of the institution of gender quotas is an increase in human capital in the economy as a whole.

Heterogeneous Treatment Effects in Groups
Gerhard Riener, Simon Wiederhold
Economics Letters,
No. 3,
2013
Abstract
We show in a laboratory experiment that the same method of group induction carries different behavioral consequences. These heterogeneous treatment effects can be directly related to the quality of the relationship established between the subjects. Our results indicate the importance of manipulation checks in group-formation tasks in economic experiments.

Subsidized Vocational Training: Stepping Stone or Trap? – Assessing Empirical Effects using Matching Techniques
Eva Dettmann, Jutta Günther
Swiss Journal of Economics and Statistics,
No. 4,
2013
Abstract
Using replacement matching on the basis of a statistical distance function we try to answer the question of whether subsidized vocational training is related to a negative image effect for the graduates. The results show that young people with equal qualifications acquired during subsidized vocational training are disadvantaged solely due to the kind of education they have received. The probability of finding adequate employment is lower than in the control group. Besides the 'general effect' of support we also find less favorable job opportunities for those who attended 'external' as compared to 'workplace-related' training.

Bildungsbeteiligung

Abstract
Gut qualifizierte Erwerbspersonen sind eine Voraussetzung für die internationale Wettbewerbsfähigkeit einer Region. Daraus leitet sich die Bildungsfunktion der Hochschulen ab. In welchem Ausmaß Kapazitäten für die Bildungsfunktion eingeplant werden müssen, hängt unter anderem von der Anzahl der Studienanfänger und der Betreuungsrelation ab. Wir betrachten dies hier für sechs exemplarische Raumordnungsregionen in west- und ostdeutschen Bundesländern.

Skill Content of Intra-european Trade Flows
Götz Zeddies
European Journal of Comparative Economics,
No. 1,
2013
Abstract
In recent decades, the international division of labor has expanded rapidly in the wake of European integration. In this context, especially Western European high-wage countries should have specialized on (human-)capital intensively manufactured goods and should have increasingly sourced labor-intensively manufactured goods, especially parts and components, from Eastern European low wage countries. Since this should be beneficial for the high-skilled and harmful to the lower-qualified workforce in high-wage countries, the opening up of Eastern Europe is often considered as a vital reason for increasing unemployment of the lower-qualified in Western Europe. This paper addresses this issue by analyzing the skill content of Western European countries’ bilateral trade using input-output techniques in order to evaluate possible effects of international trade on labor demand. Thereby, differences in factor inputs and production technologies have been considered, allowing for vertical product differentiation. In this case, skill content of bilateral exports and imports partially differs substantially, especially in bilateral trade between Western and Eastern European countries. According to the results, East-West trade should be harmful particularly to the medium-skilled in Western European countries.

Human Capital Mobility and Convergence – A Spatial Dynamic Panel Model of the German Regions
Alexander Kubis, Lutz Schneider
Abstract
Since the fall of the iron curtain in 1989, the migration deficit of the Eastern part of Germany has accumulated to 1.8 million people, which is over ten percent of its initial population. Depending on their human capital endowment, these migrants might either – in the case of low-skilled migration – accelerate or – in high-skilled case – impede convergence. Due to the availability of detailed data on regional human capital, migration and productivity growth, we are able to test how geographic mobility affects convergence via the human capital selectivity of migration. With regard to the endogeneity of the migration flows and human capital, we apply a dynamic panel data model within the framework of β-convergence and account for spatial dependence. The regressions indicate a positive, robust, but modest effect of a migration surplus on regional productivity growth. After controlling for human capital, the effect of migration decreases; this decrease indicates that skill selectivity is one way that migration impacts growth.
