Fallende Lohnquoten: Die Rolle von Technologie und Marktmacht
Matthias Mertens
Wirtschaft im Wandel,
Nr. 2,
2022
Abstract
Die Lohnquote, definiert als die Summe der Arbeitnehmerentgelte geteilt durch die Gesamtproduktion einer Volkswirtschaft, ist in den letzten 40 Jahren in vielen Ländern gefallen. Das Fallen der Lohnquote besitzt potenziell weitreichende Implikationen für das Ausmaß an Ungleichheit und für den Wohlstand von Arbeitnehmerinnen und Arbeitnehmern. Daneben kann eine fallende Lohnquote auch ein Anzeichen für einen Anstieg der Firmenmarktmacht sein. Anhand von Mikrodaten zum deutschen Verarbeitenden Gewerbe untersucht dieser Artikel, welche Rolle technologischer Wandel und steigende Firmenmarktmacht als Ursachen für das Fallen der Lohnquote spielen. Es zeigt sich, dass technologischer Wandel und ein Anstieg der Firmenmarktmacht, insbesondere auf Arbeitsmärkten, jeweils die Hälfte der fallenden Lohnquote im deutschen Verarbeitenden Gewerbe erklären. Daher können politische Maßnahmen, die Firmenmarktmacht reduzieren, nicht nur eine effizienzsteigernde Wirkung entfalten, sondern, als ein Nebeneffekt, auch den Anteil der Löhne an der Gesamtproduktion erhöhen.

Exposure to Conflict, Migrations and Long-run Education and Income Inequality: Evidence from Bosnia and Herzegovina

Nr. 11,

Abstract
We investigate the long-term relationship between conflict-related migration and individual socioeconomic inequality. Looking at the post-conflict environment of Bosnia and Herzegovina (BiH), a former Yugoslav state most heavily impacted by the conflicts of the early 1990s, the paper focuses on differences in educational performance and income between four groups: migrants, internally displaced persons, former external migrants, and those who did not move. The analysis leverages a municipality-representative survey (n≈6,000) that captured self-reported education and income outcomes as well as migration histories. We find that individuals with greater exposure to conflict had systematically worse educational performance and lower earnings two decades after the war. Former external migrants now living in BiH have better educational and economic outcomes than those who did not migrate, but these advantages are smaller for individuals who were forced to move. We recommend that policies intended to address migration-related discrepancies should be targeted on the basis of individual and family experiences caused by conflict.

Inequality in Life and Death
Martin S. Eichenbaum, Sergio Rebelo, Mathias Trabandt
IMF Economic Review,
March
2022
Abstract
We argue that the COVID epidemic disproportionately affected the economic well-being and health of poor people. To disentangle the forces that generated this outcome, we construct a model that is consistent with the heterogeneous impact of the COVID recession on low- and high-income people. According to our model, two-thirds of the inequality in COVID deaths reflect preexisting inequality in comorbidity rates and access to quality health care. The remaining third stems from the fact that low-income people work in occupations where the risk of infection is high. Our model also implies that the rise in income inequality generated by the COVID epidemic reflects the nature of the goods that low-income people produce. Finally, we assess the health-income trade-offs associated with fiscal transfers to the poor and mandatory containment policies.

Labour Market Power and Between-Firm Wage (In)Equality
Matthias Mertens
IWH Discussion Papers,
Nr. 13,
2020
Abstract
I study how labour market power affects firm wage differences using German manufacturing sector firm-level data (1995-2016). In past decades, labour market power increasingly moderated rising between-firm wage inequality. This is because high-paying firms possess high and increasing labour market power and pay wages below competitive levels, whereas low-wage firms pay competitive wages. Over time, large, high-wage, high-productivity firms generate increasingly large labour market rents while selling on competitive product markets. This provides novel insights on why such “superstar firms” are profitable and successful. Using micro-aggregated data covering most economic sectors, I validate my results for ten other European countries.

Innovation and Top Income Inequality

The Review of Economic Studies,
Nr. 1,
2019
Abstract
In this article, we use cross-state panel and cross-U.S. commuting-zone data to look at the relationship between innovation, top income inequality and social mobility. We find positive correlations between measures of innovation and top income inequality. We also show that the correlations between innovation and broad measures of inequality are not significant. Next, using instrumental variable analysis, we argue that these correlations at least partly reflect a causality from innovation to top income shares. Finally, we show that innovation, particularly by new entrants, is positively associated with social mobility, but less so in local areas with more intense lobbying activities.

Presseeinladung zum Workshop: „Regionale Ungleichheit: Gleichwertige Lebensverhältnisse in Deutschland im Fokus“ am 8. und 9. Oktober 2018 in Halle (Saale)
Ungleichheit in Deutschland: Was Wirtschaftskraft und Bevölkerungsentwicklung angeht, gibt es erhebliche Unterschiede zwischen Ost und West, zwischen Stadt und Land, zwischen Regionen mit alten Industrien und solchen mit vielen jungen Start-ups. Welche Konsequenzen sich aus diesen Unterschieden ergeben und wie die Politik darauf reagieren kann, diskutiert eine gemeinsame Veranstaltung des Instituts für Arbeitsmarkt- und Berufsforschung (IAB) und des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH).
