Coal Phase-out in Germany – Implications and Policies for Affected Regions

Pao-Yu Oei Hauke Hermann Philipp Herpich Oliver Holtemöller Benjamin Lünenburger Christoph Schult

in: Energy, 2020

Abstract

The present study examines the consequences of the planned coal phase-out in Germany according to various phase-out pathways that differ in the ordering of power plant closures. Soft-linking an energy system model with an input-output model and a regional macroeconomic model simulates the socio-economic effects of the phase-out in the lignite regions, as well as in the rest of Germany. The combination of two economic models offers the advantage of considering the phase-out from different perspectives and thus assessing the robustness of the results. The model results show that the lignite coal regions will exhibit losses in output, income and population, but a faster phase-out would lead to a quicker recovery. Migration to other areas in Germany and demographic changes will partially compensate for increasing unemployment, but support from federal policy is also necessary to support structural change in these regions.

IWH-Flash-Indikator I. Quartal und II. Quartal 2020

Katja Heinisch Oliver Holtemöller Axel Lindner Birgit Schultz

in: One-off Publications, No. 1, 2020

Abstract

Das Bruttoinlandsprodukt in Deutschland hat im vierten Quartal, so wie vom IWH-Flash-Indikator im November angezeigt, lediglich stagniert. Für das erste und das zweite Quartal 2020 deutet der IWH-Flash-Indikator wieder auf eine Zunahme des Bruttoinlandsprodukts hin (vgl. Abbildung 1). Allerdings gehen in den Indikator keine Daten ein, die der chinesischen Corona-Epidemie Rechnung tragen.

IWH-Tarif-Check: Kräftige Reale Netto-Tariflohnzuwächse für Beschäftigte in der Chemischen Industrie: Neue Gehaltsbestandteile in der Chemischen Industrie erhöhen reale Netto-Tariflohnzuwächse deutlich

Oliver Holtemöller Birgit Schultz

in: One-off Publications, No. 2, 2019

Abstract

Ende November 2019 wurde ein neuer Tarifvertrag für die Chemische Industrie abgeschlossen. Dementsprechend steigen die tabellenwirksamen Tariflöhne zum Juli 2020 um 1,5% und ein Jahr später nochmals um 1,3%. Hinzu kommen Einmalzahlungen in Höhe von 4,0% – 6,0% eines Monatsentgelts für die Zeit bis zur ersten Tariferhöhung im Juli 2020. Zusätzlich wurde erstmalig ein tarifliches Zukunftskonto im Gegenwert von zwei Tagen im Jahr 2020, drei Tagen im Jahr 2021 und danach jeweils fünf Tagen je Jahr vereinbart, die als Freizeit genommen, angespart oder ausgezahlt werden können. Dies entspricht einem Plus von 1,8 %. Hinzu kommt eine tarifliche Pflegezusatzversicherung und die Anhebung des Weihnachtsgeldes. Durch diese Zusatzvereinbarungen werden die eher niedrigen tabellenwirksamen Tariflohnsteigerungen erheblich aufgewertet. Insgesamt umfasst der Tariflohnabschluss ein Plus von mehr als 6% für eine Laufzeit von bis zu 29 Monaten.

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.

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

Oliver Holtemöller Felix Pohle

in: Economic Modelling, forthcoming

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.

On the Risk of a Sovereign Debt Crisis in Italy

Oliver Holtemöller Tobias Knedlik Axel Lindner

in: Intereconomics, forthcoming

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.

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

Christoph Schult Katja Heinisch Oliver Holtemöller

in: IWH Discussion Papers, No. 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 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.
