IWH-Flash-Indikator III. Quartal und IV. Quartal 2021

Katja Heinisch Oliver Holtemöller Axel Lindner Birgit Schultz

in: IWH Flash Indicator, No. 3, 2021

Abstract

Zu Beginn des zweiten Quartals 2021 wurde die wirtschaftliche Erholung durch die dritte Corona-Welle gebremst. Dennoch stieg das Bruttoinlandsprodukt um 1,5%. Allerdings bestanden Angebotsrestriktionen für Dienstleistungen in einigen Bereichen fort. Weil die Corona-Impfquote mittlerweile recht weit vorangeschritten ist, könnten diese Restriktionen aufgehoben werden. Es gibt aber auch Hinweise, dass die Impfungen weniger wirksam sein könnten als erhofft. Außerdem nehmen die Infektionszahlen mit Verbreitung der Delta-Variante wieder zu, was die Aussichten für den Herbst erneut eintrübt. Zudem hemmen in der gewerblichen Wirtschaft weiterhin Lieferketten- und Beschaffungsprobleme, welche zu steigenden Einkaufs­preisen führen, die Produktion. Die Wirtschaft in Deutschland dürfte laut IWH-Flash-Indikator im dritten Quartal 2021 um 1,0% expandieren und im vierten Quartal um 0,1% leicht zurückgehen (vgl. Abbildung 1).

International Trade Barriers and Regional Employment: The Case of a No-Deal Brexit

Hans-Ulrich Brautzsch Oliver Holtemöller

in: Journal of Economic Structures, No. 11, 2021

Abstract

We use the World Input–Output Database (WIOD) combined with regional sectoral employment data to estimate the potential regional employment effects of international trade barriers. We study the case of a no-deal Brexit in which imports to the United Kingdom (UK) from the European Union (EU) would be subject to tariffs and non-tariff trade costs. First, we derive the decline in UK final goods imports from the EU from industry-specific international trade elasticities, tariffs and non-tariff trade costs. Using input–output analysis, we estimate the potential output and employment effects for 56 industries and 43 countries on the national level. The absolute effects would be largest in big EU countries which have close trade relationships with the UK, such as Germany and France. However, there would also be large countries outside the EU which would be heavily affected via global value chains, such as China, for example. The relative effects (in percent of total employment) would be largest in Ireland followed by Belgium. In a second step, we split up the national effects on the NUTS-2 level for EU member states and additionally on the county (NUTS-3) level for Germany. The share of affected workers varies between 0.03% and 3.4% among European NUTS-2 regions and between 0.15% and 0.4% among German counties. A general result is that indirect effects via global value chains, i.e., trade in intermediate inputs, are more important than direct effects via final demand.

Projektion der Ausgaben für die Beamtenversorgung in Deutschland bis zum Jahr 2080

Oliver Holtemöller Götz Zeddies

in: Wirtschaft im Wandel, No. 2, 2021

Abstract

Seit einigen Jahren steigt die Zahl der Pensionäre in Deutschland. Der demographische Wandel dürfte die Versorgungsausgaben von Bund, Ländern und Gemeinden in den kommenden Jahren und Jahrzehnten deutlich zunehmen lassen. In diesem Beitrag wird die Zahl der Versorgungsempfänger bis zum Jahr 2080 vorausgeschätzt und die Versorgungsausgaben werden projiziert. Im Ergebnis zeigt sich ein teilweise deutlicher Anstieg der Versorgungsausgaben der Gebietskörperschaften. Im Verhältnis zum erwarteten Zuwachs des Steueraufkommens fällt dieser jedoch beim Bund vergleichsweise moderat und auch bei Ländern und Gemeinden nicht übermäßig hoch aus. Dies geht unter anderem auf die Annahme zurück, dass der Anteil der Beamten an der Gesamtbevölkerung in Zukunft konstant bleibt. Dagegen steht die gesetzliche Rentenversicherung größeren finanziellen Herausforderungen gegenüber, weil der Anteil der Rentenempfänger an der Gesamtbevölkerung in den kommenden Jahren zunehmen wird.

Power Generation and Structural Change: Quantifying Economic Effects of the Coal Phase-out in Germany

Katja Heinisch Oliver Holtemöller Christoph Schult

in: Energy Economics, 2021

Abstract

In the fight against global warming, the reduction of greenhouse gas emissions is a major objective. In particular, a decrease in electricity generation by coal could contribute to reducing CO2 emissions. We study potential economic consequences of a coal phase-out in Germany, using a multi-region dynamic general equilibrium model. Four regional phase-out scenarios before the end of 2040 are simulated. We find that the worst case phase-out scenario would lead to an increase in the aggregate unemployment rate by about 0.13 [0.09 minimum; 0.18 maximum] percentage points from 2020 to 2040. The effect on regional unemployment rates varies between 0.18 [0.13; 0.22] and 1.07 [1.00; 1.13] percentage points in the lignite regions. A faster coal phase-out can lead to a faster recovery. The coal phase-out leads to migration from German lignite regions to German non-lignite regions and reduces the labour force in the lignite regions by 10,100 [6300; 12,300] people by 2040. A coal phase-out until 2035 is not worse in terms of welfare, consumption and employment compared to a coal-exit until 2040.

(Since when) are East and West German Business Cycles Synchronised?

Stefan Gießler Katja Heinisch Oliver Holtemöller

in: Jahrbücher für Nationalökonomie und Statistik, No. 1, 2021

Abstract

We analyze whether, and since when, East and West German business cycles are synchronised. We investigate real GDP, unemployment rates and survey data as business cycle indicators and we employ several empirical methods. Overall, we find that the regional business cycles have synchronised over time. GDP-based indicators and survey data show a higher degree of synchronisation than the indicators based on unemployment rates. However, synchronisation among East and West German business cycles seems to have become weaker again recently.

The Effects of Fiscal Policy in an Estimated DSGE Model – The Case of the German Stimulus Packages During the Great Recession

Andrej Drygalla Oliver Holtemöller Konstantin Kiesel

in: Macroeconomic Dynamics, No. 6, 2020

Abstract

In this paper, we analyze the effects of the stimulus packages adopted by the German government during the Great Recession. We employ a standard medium-scale dynamic stochastic general equilibrium (DSGE) model extended by non-optimizing households and a detailed fiscal sector. In particular, the dynamics of spending and revenue variables are modeled as feedback rules with respect to the cyclical components of output, hours worked and private investment. Based on the estimated rules, fiscal shocks are identified. According to the results, fiscal policy, in particular public consumption, investment, and transfers prevented a sharper and prolonged decline of German output at the beginning of the Great Recession, suggesting a timely response of fiscal policy. The overall effects, however, are small when compared to other domestic and international shocks that contributed to the economic downturn. Our overall findings are not sensitive to considering fiscal foresight.

Exchange Rates and the Information Channel of Monetary Policy

Oliver Holtemöller Alexander Kriwoluzky Boreum Kwak

in: IWH Discussion Papers, No. 17, 2020

Abstract

We disentangle the effects of monetary policy announcements on real economic variables into an interest rate shock component and a central bank information shock component. We identify both components using changes in interest rate futures and in exchange rates around monetary policy announcements. While the volatility of interest rate surprises declines around the Great Recession, the volatility of exchange rate changes increases. Making use of this heteroskedasticity, we estimate that a contractionary interest rate shock appreciates the dollar, increases the excess bond premium, and leads to a decline in prices and output, while a positive information shock appreciates the dollar, decreases prices and the excess bond premium, and increases output.

Integrated Assessment of Epidemic and Economic Dynamics

Oliver Holtemöller

in: IWH Discussion Papers, No. 4, 2020

Abstract

In this paper, a simple integrated model for the joint assessment of epidemic and economic dynamics is developed. The model can be used to discuss mitigation policies like shutdown and testing. Since epidemics cause output losses due to a reduced labor force, temporarily reducing economic activity in order to prevent future losses can be welfare enhancing. Mitigation policies help to keep the number of people requiring intensive medical care below the capacity of the health system. The optimal policy is a mixture of temporary partial shutdown and intensive testing and isolation of infectious persons for an extended period of time.

Potential International Employment Effects of a Hard Brexit

Hans-Ulrich Brautzsch Oliver Holtemöller

in: IWH Discussion Papers, No. 4, 2019

Abstract

We use the World Input Output Database (WIOD) to estimate the potential employment effects of a hard Brexit in 43 countries. In line with other studies we assume that imports from the European Union (EU) to the UK will decline by 25% after a hard Brexit. The absolute effects are largest in big EU countries which have close trade relationships with the UK like Germany and France. However, there are also large countries outside the EU which are heavily affected via global value chains like China, for example. The relative effects (in percent of total employment) are largest in Malta and Ireland. UK employment will also be affected via intermediate input production. Within Germany, the motor vehicle industry and in particular the “Autostadt” Wolfsburg are most affected.
