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

Oliver Holtemöller Felix Pohle

in: Economic Modelling, im Erscheinen

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.

Industrie in der Rezession — Wachstumskräfte schwinden

Claus Michelsen Oliver Holtemöller Torsten Schmidt Stefan Kooths Timo Wollmershäuser

in: Wirtschaftsdienst, im Erscheinen

Abstract

Die führenden deutschen Wirtschaftsforschungsinstitute haben ihre Konjunkturprognose für Deutschland in ihrer Gemeinschaftsdiagnose vom Herbst 2019 deutlich nach unten korrigiert. Gründe für die schwache Entwicklung sind die nachlassende weltweite Nachfrage nach Investitionsgütern, auf deren Export die deutsche Wirtschaft spezialisiert ist, politische Unsicherheiten und strukturelle Veränderungen in der Automobilindustrie. Die Finanzpolitik stützt hingegen die gesamtwirtschaftliche Expansion. Die zukünftige Entwicklung ist stark davon abhängig, ob die Handelskonfl ikte gelöst werden können und wie der Brexit ausgestaltet wird.

Konjunktur deutlich abgekühlt — politische Risiken hoch

Roland Döhrn Oliver Holtemöller Stefan Kooths Claus Michelsen Timo Wollmershäuser

in: Wirtschaftsdienst, im Erscheinen

Abstract

Die Konjunktur in Deutschland hat sich seit Mitte des Jahres 2018 merklich abgekühlt. Der langjährige Aufschwung ist damit offenbar zu einem Ende gekommen. Die schwächere Dynamik wurde sowohl vom internationalen Umfeld als auch von branchenspezifischen Ereignissen ausgelöst. Die weltwirtschaftlichen Rahmenbedingungen haben sich — auch aufgrund politischer Risiken — eingetrübt, und das Verarbeitende Gewerbe hat mit Produktionshemmnissen zu kämpfen. Die deutsche Wirtschaft durchläuft nunmehr eine Abkühlungsphase, in der die gesamtwirtschaftliche Überauslastung zurückgeht.

On the Risk of a Sovereign Debt Crisis in Italy

Oliver Holtemöller Tobias Knedlik Axel Lindner

in: Intereconomics, im Erscheinen

Abstract

The intention for the Italian government to stimulate business activity via large increases in government spending is not in line with the stabilisation of the public debt ratio. Instead, if such policy were implemented, the risk of a sovereign debt crisis would be high. In this article, we analyse the capacity of the Italian economy to shoulder sovereign debt under different scenarios. We conclude that focusing on growth enhancing structural reforms, would allow for moderate increases in public expenditure.

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, im Erscheinen

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.

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

Christoph Schult Katja Heinisch Oliver Holtemöller

in: IWH-Diskussionspapiere, Nr. 16, 2019

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. Using a multi-region dynamic general equilibrium model, this paper studies potential economic consequences of a coal phase-out in Germany. Different regional phase-out scenarios are simulated with varying timing structures. We find that a politically induced coal phase-out would lead to an increase in the national unemployment rate by about 0.10 percentage points from 2020 to 2040, depending on the specific scenario. The effect on regional unemployment rates varies between 0.18 to 1.07 percentage points in the lignite regions. However, 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 10,000 people by 2040.

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

Stefan Gießler Katja Heinisch Oliver Holtemöller

in: IWH-Diskussionspapiere, Nr. 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-Diskussionspapiere, Nr. 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.
