Rekordschulden gegen Corona-Folgen sind finanzierbar – schuldenfinanzierte Konsumstimulierung aber nicht zielführend

Oliver Holtemöller

in: ifo Schnelldienst, No. 8, 2020

Abstract

Auf große Wirtschaftskrisen reagiert die Finanzpolitik häufig mit einer massiven Ausweitung der öffentlichen Verschuldung, so auch in der gegenwärtigen Coronakrise. In diesem Beitrag wird gezeigt, dass die deutsche Schuldenbremse die Tragfähigkeit der öffentlichen Finanzen auch dann gewährleistet, wenn im Abstand von zehn Jahren Krisen auftreten, in denen die Neuverschuldungsgrenze außer Kraft gesetzt wird. Die Tragfähigkeit zusätzlicher Staatsschulden begründet jedoch nicht deren Sinnhaftigkeit. Diskretionäre Finanzpolitik zur Stimulierung der gesamtwirtschaftlichen Nachfrage leistet insgesamt einen eher kleinen Anteil zur Stabilisierung der realwirtschaftlichen Entwicklung. Maßnahmen zur Eindämmung der Corona-Epidemie, für den Ausgleich tatsächlicher sozialer und wirtschaftlicher Schäden und für die Aufrechterhaltung des Bildungsbetriebs unter den Bedingungen einer Epidemie könnten einen wichtigeren Beitrag zur Krisenbekämpfung leisten als kurzfristige Nachfragestimulierung.

IWH-Flash-Indikator III. Quartal und IV. Quartal 2020

Katja Heinisch Oliver Holtemöller Axel Lindner Birgit Schultz

in: One-off Publications, No. 3, 2020

Abstract

Die Corona-Pandemie hat die deutsche Wirtschaft im Frühjahr 2020 in eine tiefe Rezession gerissen. Das Bruttoinlandsprodukt sank im zwei­ten Quartal 2020 um 10,1%, nach einem Rückgang von 2,0% im Quartal zuvor. Dieser massive Wirtschaftseinbruch war insbesondere den Lockdown-Maßnahmen geschuldet, die das öffentliche und wirtschaft­liche Leben zeitweise auf ein Minimum reduzierten. Seit Anfang Mai wurden die Restriktionen zur Eindämmung der Pandemie gelockert, und die wirtschaftlichen Aktivitäten haben wieder deutlich zugenom­men. Der Tiefpunkt der Rezession ist also durchschritten, allerdings dürfte die Rückkehr zum Vorkrisenniveau auch aufgrund der wieder höheren Fallzahlen und der damit verbundenen Unsicherheit noch länger auf sich warten lassen. Die Wirtschaft dürfte im dritten Quartal 2020 um 4,6% und im vierten Quartal dann um 4,0% expandieren. (vgl. Abbildung).

Ohne Konsumverzicht keine CO2-Reduktion – auch, wenn man auf Innovation setzt

Oliver Holtemöller

in: Wirtschaft im Wandel, No. 2, 2020

Abstract

In der Diskussion über die deutsche Klimapolitik steht häufig die Frage im Mittelpunkt, mit welchen Instrumenten sich eine Reduktion der CO<sub>2</sub>-Emissionen am wirksamsten erreichen lässt. So werden etwa die Vorund Nachteile von CO<sub>2</sub>-Steuern im Vergleich zur Versteigerung von CO<sub>2</sub>-Zertifikaten und die Reihenfolge der Abschaltung von Braunkohlekraftwerken diskutiert. Neben diesen eher mikroökonomischen Aspekten hat die Klimapolitik weitreichende makroökonomische Konsequenzen.

Nowcasting East German GDP Growth: a MIDAS Approach

João Carlos Claudio Katja Heinisch Oliver Holtemöller

in: Empirical Economics, forthcoming

Abstract

Economic forecasts are an important element of rational economic policy both on the federal and on the local or regional level. Solid budgetary plans for government expenditures and revenues rely on efficient macroeconomic projections. However, official data on quarterly regional GDP in Germany are not available, and hence, regional GDP forecasts do not play an important role in public budget planning. We provide a new quarterly time series for East German GDP and develop a forecasting approach for East German GDP that takes data availability in real time and regional economic indicators into account. Overall, we find that mixed-data sampling model forecasts for East German GDP in combination with model averaging outperform regional forecast models that only rely on aggregate national information.

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, forthcoming

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.

Employment Effects of Introducing a Minimum Wage: The Case of Germany

Oliver Holtemöller Felix Pohle

in: Economic Modelling, No. 7, 2020

Abstract

Income inequality has been a major concern of economic policy makers for several years. Can minimum wages help to mitigate inequality? In 2015, the German government introduced a nationwide statutory minimum wage to reduce income inequality by improving the labour income of low-wage employees. However, the employment effects of wage increases depend on time and region specific conditions and, hence, they cannot be known in advance. Because negative employment effects may offset the income gains for low-wage employees, it is important to evaluate minimum-wage policies empirically. We estimate the employment effects of the German minimum-wage introduction using panel regressions on the state-industry-level. We find a robust negative effect of the minimum wage on marginal and a robust positive effect on regular employment. In terms of the number of jobs, our results imply a negative overall effect. Hence, low-wage employees who are still employed are better off at the expense of those who have lost their jobs due to the minimum wage.

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.

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.
