Viele Ökonomen haben prognostiziert, dass die Anzahl der geringfügigen Beschäftigungs- verhältnisse (Minijobs) als Folge des flächendeckenden gesetzlichen Mindestlohns deutlich zurückgehen wird. Tatsächlich hat sich die Anzahl der gewerblichen Minijobs im Juni 2015 um ca. 190 000 Beschäftigungsverhältnisse gegenüber dem Vorjahr reduziert; dies entspricht einem Rückgang um 2,7%.

We show that the major part of the plant size–wage premium in Germany is reflected in different wage growth patterns in plants of different size. This is consistent with the hypothesis that large firms ‘produce’ more skilled workers over time.

We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous findings, our dynamic models indicate an inverse u-shaped association between bmi and wages. As the implied maximum occurs in the ‘overweight’ category, the positive trend in weight may not yet constitute a major limitation to productivity. Further investigation points out a stronger association among young workers and workers with jobs that are less protected. Work satisfaction of young workers is associated with bmi beyond the effect of earnings.

The authors investigate immigrants’ and natives’ labor supply to the firm within an estimation approach based on a dynamic monopsony framework. Applying duration models that account for unobserved worker heterogeneity to a large administrative employer–employee data set for Germany, they find that immigrants supply labor less elastically to firms than do natives. Under monopsonistic wage setting, the estimated elasticity differential predicts a 7.7 log points wage penalty for immigrants thereby accounting for the entire unexplained native–immigrant wage differential of 5.8 to 8.2 log points. When further distinguishing immigrant groups differing in their time spent in the German labor market, their immigration cohort, and their age at entry, the authors find that the observed unexplained wage differential is larger for those groups that show a larger elasticity differential relative to natives. These findings not only suggest that search frictions are a likely cause of employers’ more pronounced monopsony power over their immigrant workers but also imply that employers profit from discriminating against immigrants.

Knapp ein Viertel der Arbeitnehmer in Ostdeutschland hatte im Jahr 2013 einen Bruttostundenlohn von weniger als 8,50 Euro. Dies zeigen vom IWH erstmals für das Jahr 2013 durchgeführte Berechnungen auf Basis aktueller Befragungsergebnisse. Damit liegt der Anteil der unter diesem Stundensatz verdienenden Personen in etwa auf dem Vorjahreswert. Besonders hoch ist dabei der Anteil in den arbeitsintensiven Branchen.

We argue that the vast bulk of movements in aggregate real economic activity during the Great Recession were due to financial frictions. We reach this conclusion by looking through the lens of an estimated New Keynesian model in which firms face moderate degrees of price rigidities, no nominal rigidities in wages, and a binding zero lower bound constraint on the nominal interest rate. Our model does a good job of accounting for the joint behavior of labor and goods markets, as well as inflation, during the Great Recession. According to the model the observed fall in total factor productivity and the rise in the cost of working capital played critical roles in accounting for the small drop in inflation that occurred during the Great Recession.

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.

Using linked employer–employee panel data for West Germany that include direct information on the competition faced by plants, we investigate the effect of product market competition on the gender pay gap. Controlling for match fixed effects, we find that intensified competition significantly lowers the unexplained gap in plants with neither collective agreements nor a works council. Conversely, there is no effect in plants with these types of worker codetermination, which are unlikely to have enough discretion to adjust wages in the short run. We also document a larger competition effect in plants with few females in their workforces. Our findings are in line with Beckerian taste-based employer wage discrimination that is limited by competitive forces.

Wanderten in den vergangenen 25 Jahren zahlreiche Menschen aus Ostdeutschland ab, so ist dieser Trend per saldo jüngst zum Erliegen gekommen. Dies hat auch damit zu tun, dass sich die Arbeitsmarktperspektiven verbessert haben. Die durchschnittlichen Bruttomonatsverdienste der Vollzeitbeschäftigten liegen in Ostdeutschland jedoch erst bei etwa 70 Prozent der Verdienste im Westen. Die wirtschaftlichen Möglichkeiten der Menschen in Ostdeutschland liegen aber viel näher am westdeutschen Niveau. So betragen die verfügbaren Einkommen im Osten immerhin 84 Prozent in Relation zum Westen. Berücksichtigt man noch Unterschiede der Preisniveaus, so kommt man auf ein reales Konsumniveau im Osten, das bei etwa 90 Prozent des Westniveaus liegt. Nach dem amerikanischen Bürgerkrieg war die Lücke zwischen der Produktion je Einwohner in den Nord- und den Südstaaten etwa so groß wie vor 25 Jahren zwischen Ost- und Westdeutschland; in den USA hat es aber 100 Jahre gedauert, bis sich die Lücke bis auf 10 Prozent geschlossen hatte. Auch verglichen mit anderen Transformationsländern wie beispielsweise Tschechien oder Polen ist der Aufholprozess Ostdeutschland deutlich weiter.

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.
