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

Oliver Holtemöller Götz Zeddies

in: IWH Technical Reports, No. 2, 2021

Abstract

In den vergangenen Jahren hat die Zahl der Pensionäre (ehemalige Beamte, Richter und Soldaten) in Deutschland deutlich zugenommen. Damit gehen immer höhere Versorgungsausgaben einher, die Bund, Länder und Gemeinden aufbringen müssen. Der demographische Wandel könnte in Zukunft nicht nur ausgabeseitig eine Herausforderung aufgrund weiter steigender Versorgungsausgaben darstellen, sondern auch auf der Einnahmeseite, weil die Versorgungslasten von immer weniger Steuerzahlern getragen werden müssen. Im Folgenden werden mit Hilfe eines Kohorten-Komponenten-Modells die Zahl der Versorgungsempfänger und die daraus resultierenden Versorgungsausgaben für Bund, Länder und Gemeinden bis zum Jahr 2080 geschätzt und die Konsequenzen für die öffentlichen Haushalte abgeleitet. Es zeigt sich, dass die Versorgungsausgaben der Gebietskörperschaften zwar ansteigen, die Versorgungs-Steuerquote insgesamt allerdings relativ stabil bleibt. Da die Zahl der Versorgungsempfänger bei Ländern und Gemeinden bis zum Jahr 2080 kaum zunehmen und beim Bund sogar zurückgehen wird, stehen die Gebietskörperschaften infolge der Pensionslasten vor weitaus kleineren finanziellen Herausforderungen als die gesetzliche Rentenversicherung angesichts des wachsenden Anteils der Rentenempfänger an der Gesamtbevölkerung.

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

Katja Heinisch Oliver Holtemöller Axel Lindner Birgit Schultz

in: IWH Flash Indicator, No. 2, 2021

Abstract

Die hohen Infektionszahlen und der seit November 2020 immer wieder verlängerte Lockdown führten im ersten Quartal 2021 zu einem Rückgang des Bruttoinlandsprodukts um 1,7%. Insbesondere der private Konsum litt unter den strengen staatlichen Restriktionen. Hingegen liefen die Warenexporte gut und verhinderten einen stärkeren Einbruch der deutschen Wirtschaft. Nachdem bereits Ende des ersten Quartals in einigen Regionen Deutschlands begonnen wurde, die Restriktionen etwas zurückzunehmen, kam es aus Sorge vor einem weiteren Anwachsen der dritten Corona-Welle in der zweiten Aprilhälfte zu einer bundesweit regulierten Verschärfung der Lockdown-Regeln. Seit Anfang Mai gehen die Corona-Neuerkrankungen in Deutschland nun zurück. Das dürfte wohl neben einem saisonalen Effekt auch auf die endlich in Fahrt gekommene Impfkampagne zurückzuführen sein. Der Lockdown dürfte in absehbarer Zeit aufgehoben werden können. Insbesondere die private Konsumnachfrage dürfte davon profitieren und zusammen mit der robusten Nachfrage aus dem Ausland die Wirtschaftsleistung laut IWH-Flash-Indikator im zweiten Quartal 2021 um 2,1% und im dritten Quartal um 2,4% steigen lassen.

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.

(Since When) Are East and West German Business Cycles Synchronised?

Stefan Gießler Katja Heinisch Oliver Holtemöller

in: IWH Discussion Papers, No. 7, 2019

Abstract

This paper analyses 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 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, recently synchronisation among East and West German business cycles seems to become weaker, in line with international evidence.
