The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?
Matthias Mertens, Steffen Müller
Journal of Comparative Economics,
No. 3,
2022
Abstract
East German manufacturers’ revenue productivity is substantially below West German levels, even three decades after German unification. Using firm-product-level data with product quantities and prices, we analyze the role of product specialization and show that the prominent “extended work bench hypothesis” cannot explain these sustained productivity differences. Eastern firms specialize in simpler product varieties generating less consumer value and being manufactured with less or cheaper inputs. Yet, such specialization cannot explain the productivity gap because Eastern firms are physically less productive for given product prices. Hence, there is a genuine price-adjusted physical productivity disadvantage of Eastern compared to Western firms.

Energy crisis in Germany
Dwindling gas supplies from Russia and soaring prices for gas and electricity are leading to massive real income losses and a recession in Europe and Germany. The Halle Institute for Economic Research (IWH) forecasts that German gross domestic product (GDP) will increase by 1.1% in 2022 and decrease by 1.4% in 2023. Consumer prices are expected to rise by 7.9% in 2022 and 9.5% in 2023.

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.

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%.

Die Ost-West-Produktivitätslücke: Die Rolle von Produktspezialisierung, Produktpreisunterschieden und physischer Produktivität
Matthias Mertens, Steffen Müller
Wirtschaft im Wandel,
No. 1,
2022
Abstract
Auch 30 Jahre nach der Deutschen Vereinigung erreicht die ostdeutsche Wirtschaft nur 82% der westdeutschen Arbeitsproduktivität. Dieser Unterschied in der gesamtwirtschaftlichen Arbeitsproduktivität steht in engem Zusammenhang mit vielen wirtschaftlichen und gesellschaftlichen Problemen, denen Ostdeutschland heute gegenübersteht. Auf Basis differenzierter Daten zu den einzelnen Produkten, die Firmen im deutschen Verarbeitenden Gewerbe herstellen, untersuchen wir in diesem Beitrag, wie sich ost- und westdeutsche Firmen bezüglich Produktspezialisierung, Produktpreisen und technischer Effizienz unterscheiden. Wir zeigen auf, dass der Osten – entgegen der Hypothese der „verlängerten Werkbank“ – nicht aufgrund einer Spezialisierung auf Vorprodukte weniger produktiv als der Westen ist. Obwohl Ostprodukte zu deutlich geringeren Preisen verkauft werden, können auch Preisunterschiede zwischen Ost- und Westfirmen den Produktivitätsrückstand nicht erklären. Stattdessen sind Faktoren, welche die physische Produktivität (technische Effizienz) von Unternehmen beeinflussen, entscheidend, um den Produktivitätsrückstand auf Unternehmensebene zu erklären.

Price shock jeopardises recovery of German economy
Russia’s war in Ukraine is hitting the German economy primarily via an energy price shock, but also by disrupting trade flows and causing general uncertainty. At the same time, however, the economy is receiving a strong boost from the lifting of many pandemic restrictions. The Halle Institute for Economic Research (IWH) forecasts that gross domestic product will increase by 3.1% in 2022. The consumer price index will be 4.8% higher than one year ago. The war affects the East German eco-nomy about as hard as the economy in Germany as a whole.

Micro-mechanisms behind Declining Labor Shares: Rising Market Power and Changing Modes of Production
Matthias Mertens
International Journal of Industrial Organization,
March
2022
Abstract
I derive a micro-founded framework showing how rising firm market power on product and labor markets and falling aggregate labor output elasticities provide three competing explanations for falling labor shares. I apply my framework to 20 years of German manufacturing sector micro data containing firm-specific price information to study these three distinct drivers of declining labor shares. I document a severe increase in firms’ labor market power, whereas firms’ product market power stayed comparably low. Changes in firm market power and a falling aggregate labor output elasticity each account for one half of the decline in labor's share.

The Impact of Active Aggregate Demand on Utilisation-adjusted TFP
Konstantin Gantert
IWH Discussion Papers,
No. 9,
2022
Abstract
Non-clearing goods markets are an important driver of capacity utilisation and total factor productivity (TFP). The trade-off between goods prices and household search effort is central to goods market matching and therefore drives TFP over the business cycle. In this paper, I develop a New-Keynesian DSGE model with capital utilisation, worker effort, and expand it with goods market search-and-matching (SaM) to model non-clearing goods markets. I conduct a horse-race between the different capacity utilisation channels using Bayesian estimation and capacity utilisation survey data. Models that include goods market SaM improve the data fit, while the capital utilisation and worker effort channels are rendered less important compared to the literature. It follows that TFP fluctuations increase for demand and goods market mismatch shocks, while they decrease for technology shocks. This pattern increases as goods market frictions increase and as prices become stickier. The paper shows the importance of non-clearing goods markets in explaining the difference between technology and TFP over the business cycle.

The Crisis is Gradually Being Overcome

No. 10,
2021
Abstract
Die führenden Wirtschaftsforschungsinstitute senken ihre BIP-Wachstumsprognose für 2021 von 3,7 % auf 2,4 %. Dafür ist insbesondere die schwächelnde Industrieproduktion verantwortlich, die unter Lieferengpässen leidet. Die internationale Konjunktur erholt sich zwar von den Verwerfungen der Corona-Pandemie, aber nur langsam, da die Impffortschritte regional unterschiedlich sind. Die Verbraucherpreise haben sich 2021 stark erhöht.

Production bottlenecks delay recovery
The German recovery made good progress over the summer 2021. However, bottlenecks in sea transport and the production of intermediate goods are weighing on world trade. The rise in raw material prices has prompted inflation rates to spike, and an increase in new infections is clouding the outlook again. A weak final quarter is therefore to be expected. The Halle Institute for Economic Research (IWH) forecasts that German gross domestic product (GDP) will increase by 2.2% in 2021 and 3.6% in 2022 (East Germany: 1.8% and 2.8%).
