Minimum Wages, Productivity, and Reallocation

Abstract
We study the productivity effect of the German national minimum wage by applying administrative firm data. At the firm level, we confirm positive effects on wages and negative employment effects and document higher productivity even net of output price increases. We find higher wages but no employment effects at the level of aggregate industry × region cells. The minimum wage increased aggregate productivity in manufacturing. We do not find that employment reallocation across firms contributed to these aggregate productivity gains, nor do we find improvements in allocative efficiency. Instead, the productivity gains from the minimum wage result from within-firm productivity improvements only.

Minimum Wages, Productivity, and Reallocation

No. 8,

Abstract
We study the productivity effect of the German national minimum wage combining administrative firm datasets. We analyze firm- and market-level effects, considering output price changes, factor substitution, firm entry and exit, labor reallocation, and short- versus long-run effects. We document higher firm productivity even net of output price increases. Productivity gains are persistent in manufacturing and service sectors. The minimum wage also increased manufacturing productivity at the aggregate level. Neither firm entry and exit nor other forms of employment reallocation between firms contributed to these gains. Instead, aggregate productivity gains from the minimum wage solely stem from within-firm productivity improvements.

European Firm Concentration and Aggregate Productivity
Tommaso Bighelli, Filippo di Mauro, Marc Melitz, Matthias Mertens
Journal of the European Economic Association,
No. 2,
2023
Abstract
This paper derives a European Herfindahl–Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, European concentration rose due to a reallocation of economic activity toward large and concentrated industries. Over the same period, productivity gains from an increasing allocative efficiency of the European market accounted for 50% of European productivity growth while markups stayed constant. Using country-industry variation, we show that changes in concentration are positively associated with changes in productivity and allocative efficiency. This holds across most sectors and countries and supports the notion that rising concentration in Europe reflects a more efficient market environment rather than weak competition and rising market power.

Strukturwandel zulassen

Abstract
Nach den beschlossenen Ausstiegen Deutschlands aus der Kernenergie und der Kohleverstromung galten Gaskraftwerke als Brücke hin zu einer CO2-neutralen Volkswirtschaft. Billiges Pipelinegas aus Russland half der energieintensiven Industrie in Deutschland aber auch, bei den Energiekosten die preisliche Wettbewerbsfähigkeit mit internationalen Wettbewerbern nicht komplett zu verlieren. So waren in den Jahren vor dem russischen Überfall auf die Ukraine die Gaspreise für industrielle Abnehmer in Deutschland auf dem Niveau, das die amerikanische oder asiatische Konkurrenz zahlen musste. Die dramatischen Preisanstiege für Erdgas (aber auch für Kraftwerkskohle und Strom) nach Kriegsbeginn und dem Gaslieferstopp durch Russland waren ein Schock für die deutsche Industrie.

Gas storages full – economic outlook less gloomy
The severe slump in the German economy expected last fall has not materialised because gas supply stabilises. However, due to high inflation, higher real interest rates and declining real incomes, the economy is likely to remain weak. In its spring forecast, the Halle Institute for Economic Research (IWH) expects production to grow by just 0.4% in 2023, and inflation to remain high at 5.8%.

Konjunktur aktuell: Gasspeicher voll – Konjunkturaussichten weniger trüb
Konjunktur aktuell,
No. 1,
2023
Abstract
Im Frühjahr 2023 wirken gegenläufige Kräfte auf die Weltwirtschaft: Das Ende des Corona-Lockdowns in China gibt vor allem dem asiatischen Raum einen Schub, doch die anhaltend hohe Inflation belastet die fortgeschrittenen Volkswirtschaften weltweit. Alles in allem bleibt die internationale Konjunktur 2023 schwach. Für die deutsche Wirtschaft blieb der vielfach erwartete deutliche Einbruch aus, denn die Gasversorgungslage hat sich zunächst stabilisiert. Dennoch dürfte die Konjunktur wegen der Energiekosten, hoher Inflation, gestiegener Realzinsen und rückläufiger Realeinkommen schwach bleiben. Das Bruttoinlandsprodukt dürfte im Jahr 2023 um lediglich 0,4% zulegen, und die Inflationsrate bleibt mit 5,8% hoch.

Economic growth, public finances and greenhouse gas emissions in the medium term
According to the Halle Institute for Economic Research (IWH) and its medium-term projection of the German economy, growth in the next six years will be about the same as in the past six years, at 1% per year. The national budget will remain in deficit, but the debt level will decline again relative to the gross domestic product (GDP) from 2024 onwards. At this rate of economic expansion, greenhouse gas emissions will continue to decline in the medium term, but at a much slower rate than necessary to meet the national emission reduction targets.

Robots, Occupations, and Worker Age: A Production-unit Analysis of Employment
Liuchun Deng, Steffen Müller, Verena Plümpe, Jens Stegmaier
IWH Discussion Papers,
No. 5,
2023
Abstract
We analyse the impact of robot adoption on employment composition using novel micro data on robot use in German manufacturing plants linked with social security records and data on job tasks. Our task-based model predicts more favourable employment effects for the least routine-task intensive occupations and for young workers, with the latter being better at adapting to change. An event-study analysis of robot adoption confirms both predictions. We do not find adverse employment effects for any occupational or age group, but churning among low-skilled workers rises sharply. We conclude that the displacement effect of robots is occupation biased but age neutral, whereas the reinstatement effect is age biased and benefits young workers most.

Sources of Large Firms’ Market Power and Why It Matters
Filippo di Mauro, Matthias Mertens, Bernardo Mottironi
VOXEU COLUMN,
January
2023
Abstract
Excessive market power has detrimental effects on the functioning of the economy, raising consumer prices, distorting the allocation of resources, and creating welfare losses. The existing literature has largely focussed on competition in product markets. This column argues that it is important to differentiate between various sources of firm market power on output and input (most notably labour) markets. European firm-level data reveals that large firms charge lower markups in product markets but exert their market power significantly in labour markets. Competition authorities can and must distinguish between the sources of market power when attempting to regulate it.

The Geography of Information: Evidence from the Public Debt Market

Journal of Economic Geography,
No. 1,
2023
Abstract
nWe investigate the link between the spatial concentration of firms in large, central metropolitans (i.e. urban agglomeration) and the cost of public corporate debt. Looking at bond issues over the period 1985–2014, we find that bonds issued by companies headquartered in urban agglomerates have lower at-issue yield spreads than bonds issued by firms based in remote, sparsely populated areas. Measures of the count of institutional bondholders in a firm’s vicinity confirm that the spatial cross-sectional variation in bond spreads is driven by the proximity of metropolitan firms to large concentrations of institutional investors. Our results are robust to controls for firm productivity and governance, analyst following, and exogenous shocks to institutional investor attention. The effect of headquarters location on bond spreads is especially pronounced for more difficult to value, speculative-grade bonds, bonds issued by smaller, less visible firms and bonds issued without protective covenants. Overall, we provide evidence that the geographical distribution of firms and investors generates a corresponding distribution of value-relevant, firm-level information that affects its cost of capital.
