European Firm Concentration and Aggregate Productivity
Tommaso Bighelli, Filippo di Mauro, Marc Melitz, Matthias Mertens
Journal of the European Economic Association,
forthcoming
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.

Financial Linkages and Sectoral Business Cycle Synchronization: Evidence from Europe
Hannes Böhm, Julia Schaumburg, Lena Tonzer
IMF Economic Review,
forthcoming
Abstract
We analyze whether financial integration leads to converging or diverging business cycles using a dynamic spatial model. Our model allows for contemporaneous spillovers of shocks to GDP growth between countries that are financially integrated and delivers a scalar measure of the spillover intensity at each point in time. For a financial network of ten European countries from 1996 to 2017, we find that the spillover effects are positive on average and much larger during periods of financial stress, pointing towards stronger business cycle synchronization. Dismantling GDP growth into value added growth of ten major industries, we observe that spillover intensities vary significantly. The findings are robust to a variety of alternative model specifications.

The East German economy expanded strongly in the first half of 2022, but falls into recession in the second half of the year ‒ Implications of the Joint Economic Forecast Autumn 2022 and of Länder data from recent publications of the Statistical Office
The energy crisis is pushing the German economy into recession. This also affects the economy in East Germany. According to the Halle Institute for Economic Research (IWH), East German production will expand at a slightly stronger rate of 1.5% than in Germany as a whole. For the coming year, the decline in East Germany is expected to be less pronounced than in the west at 0.1% (Germany: ‒0.4%). For 2024, the economists forecast a growth of 1.7% (Germany: 1.9%).

Labour mobility is part of structural change
The coal phase-out will also change the affected regions in that part of the workforce will migrate. Politicians should take this process into account in structural policy, because it cannot be completely prevented. A study published by the Halle Institute for Economic Research (IWH) illustrates this with a historical example.

What Does Codetermination Do?
Simon Jäger, Benjamin Schoefer
ILR Review,
No. 4,
2022
Abstract
The authors provide a comprehensive overview of codetermination, that is, worker representation in firms’ governance and management. The available micro evidence points to zero or small positive effects of codetermination on worker and firm outcomes and leaves room for moderate positive effects on productivity, wages, and job stability. The authors also present new country-level, general-equilibrium event studies of codetermination reforms between the 1960s and 2010s, finding no effects on aggregate economic outcomes or the quality of industrial relations. They offer three explanations for the institution’s limited impact. First, existing codetermination laws convey little authority to workers. Second, countries with codetermination laws have high baseline levels of informal worker voice. Third, codetermination laws may interact with other labor market institutions, such as union representation and collective bargaining. The article closes with a discussion of the implications for recent codetermination proposals in the United States.

Energy Markets and Global Economic Conditions
Christiane Baumeister, Dimitris Korobilis, Thomas K. Lee
Review of Economics and Statistics,
No. 4,
2022
Abstract
We evaluate alternative indicators of global economic activity and other market funda-mentals in terms of their usefulness for forecasting real oil prices and global petroleum consumption. World industrial production is one of the most useful indicators. However, by combining measures from several different sources we can do even better. Our analysis results in a new index of global economic conditions and measures for assessing future energy demand and oil price pressures. We illustrate their usefulness for quantifying the main factors behind the severe contraction of the global economy and the price risks faced by shale oil producers in early 2020.

Gefahr einer Gaslücke gegenüber April deutlich verringert – aber Versorgungsrisiken bleiben
Die Wahrscheinlichkeit einer Versorgungslücke mit Erdgas im Fall eines Stopps russischer Lieferungen ist gegenüber April deutlich gesunken. Zu diesem Ergebnis kommt eine aktualisierte Simulationsrechnung der an der Gemeinschaftsdiagnose beteiligten Institute. Trotz mittlerweile deutlich besser gefüllter Speicher sind damit aber noch nicht alle Risiken für die Gasversorgung der Industrie im Winterhalbjahr 2022/2023 gebannt. Es ist daher ratsam, zeitnah die Preissignale bei den Verbrauchern ankommen zu lassen.

War drives up energy prices ‒ High inflation weighs on economy
While the lifting of nationwide coronavirus regulations boosts many service sectors such as the hospitality industry, supply bottlenecks are likely to weigh on the manufacturing sector throughout the summer and high inflation will dampen private consumption. Gross domestic product (GDP) in Germany is expected to decline slightly in the second quarter of 2022. The situation in the manufacturing sector is expected to ease towards the end of the year. The Halle Institute for Economic Research (IWH) forecasts that GDP will increase by 1.5% in 2022, following an increase by 2.9% in 2021. In East Germany, GDP will increase by 1%.

Aktuelle Trends: Deutsche Gasspeicher erreichen jahreszeitüblichen Füllstand
Oliver Holtemöller, Christoph Schult
Wirtschaft im Wandel,
No. 2,
2022
Abstract
Seit dem Angriff Russlands auf die Ukraine wird intensiv diskutiert, welche Folgen ein Lieferstopp für russisches Gas für die deutsche Konjunktur hätte. Die Projektgruppe Gemeinschaftsdiagnose hat in ihrem Frühjahrsgutachten berechnet, wann in einem solchen Fall die Gasnachfrage in Deutschland nicht mehr vollständig bedient werden könnte und es somit zu einer Rationierung von Gas kommen würde. Diese Berechnungen basierten auf der Annahme eines Lieferstopps Mitte April. Da die deutschen Gasspeicher zu Jahresbeginn unterdurchschnittlich befüllt waren, wäre infolge eines solchen Lieferstopps im Winter 2022/2023 mit einer Rationierung der deutschen Industrie und damit mit erheblichen konjunkturellen Einbußen zu rechnen gewesen.
