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.

Importwettbewerb und Firmenproduktivität
Viktor Slavtchev
Wirtschaft im Wandel,
Nr. 1,
2021
Abstract
Dieser Beitrag untersucht für Unternehmen aus dem Verarbeitenden Gewerbe in Deutschland empirisch, ob der Wettbewerbsdruck durch Importe zu einer Steigerung der Produktivität führt. Um die Reaktionen der einheimischen Unternehmen besser zu verstehen, werden auch Effekte auf Output, Beschäftigung und FuE-Aktivitäten der Unternehmen analysiert. Die Ergebnisse zeigen, dass die Anreize der Unternehmen, in eine Erhöhung ihrer Produktivität zu „investieren“, von der Art der importierten Güter abhängen sowie davon, wie schwierig es für die einheimischen Unternehmen ist, mit der Konkurrenz mitzuhalten. Auf Importe von vergleichsweise technologisch einfachen und arbeitsintensiven Produkten aus Niedriglohnländern reagieren einheimische Unternehmen nicht mit einer Erhöhung ihrer Produktivität; vielmehr reduzieren sie Output und Beschäftigung. Dagegen steigt die Produktivität einheimischer Unternehmen als Reaktion auf Wettbewerbsdruck durch Importe von kapital- und technologieintensiven Gütern aus Industrieländern – jedoch nicht aufgrund höherer FuE-Ausgaben; ein Rückgang von Output und Beschäftigung ist in diesem Fall nicht beobachtbar.

Public Bank Guarantees and Allocative Efficiency
Reint E. Gropp, Andre Guettler, Vahid Saadi

Abstract
A natural experiment and matched bank/firm data are used to identify the effects of bank guarantees on allocative efficiency. We find that with guarantees in place unproductive firms receive larger loans, invest more, and maintain higher rates of sales and wage growth. Moreover, firms produce less productively. Firms also survive longer in banks’ portfolios and those that enter guaranteed banks’ portfolios are less profitable and productive. Finally, we observe fewer economy-wide firm exits and bankruptcy filings in the presence of guarantees. Overall, the results are consistent with the idea that guaranteed banks keep unproductive firms in business for too long.

Asymmetric Investment Responses to Firm-specific Forecast Errors
Julian Berner, Manuel Buchholz, Lena Tonzer
Abstract
This paper analyses how firm-specific forecast errors derived from survey data of German manufacturing firms over 2007–2011 affect firms’ investment propensity. Understanding how forecast errors affect firm investment behaviour is key to mitigate economic downturns during and after crisis periods in which forecast errors tend to increase. Our findings reveal a negative impact of absolute forecast errors on investment. Strikingly, asymmetries arise depending on the size and direction of the forecast error. The investment propensity declines if the realised situation is worse than expected. However, firms do not adjust investment if the realised situation is better than expected suggesting that the uncertainty component of the forecast error counteracts positive effects of unexpectedly favorable business conditions. Given that the fraction of firms making positive forecast errors is higher after the peak of the recent financial crisis, this mechanism can be one explanation behind staggered economic growth and slow recovery following crises.

Nowcasting East German GDP Growth: a MIDAS Approach
João Carlos Claudio, Katja Heinisch, Oliver Holtemöller
Empirical Economics,
Nr. 1,
2020
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.

Spillovers of Asset Purchases Within the Real Sector: Win-Win or Joy and Sorrow?

IWH Discussion Papers,
Nr. 22,
2019
Abstract
Events which have an adverse or positive effect on some firms can disseminate through the economy to firms which are not directly affected. By exploiting the first large sovereign bond purchase programme of the ECB, this paper investigates whether more lending to some firms spill over to firms in the surroundings of direct beneficiaries. Firms operating in the same industry and region invest less and reduce employment. The paper shows the importance to consider spillover effects when assessing unconventional monetary policies: Differences between treatment and control groups can be entirely attributed to negative effects on the control group.

Gemeinschaftsdiagnose Herbst 2019: Konjunktur kühlt weiter ab – Industrie in der Rezession
Berlin, 2. Oktober 2019 – Die führenden deutschen Wirtschaftsforschungsinstitute haben ihre Konjunkturprognose für Deutschland deutlich nach unten korrigiert. Waren sie im Frühjahr noch von einer Zunahme des Bruttoinlandsprodukts von 0,8% im Jahr 2019 ausgegangen, erwarten sie nun nur noch 0,5%. Gründe für die schwache Entwicklung sind die nachlassende weltweite Nachfrage nach Investitionsgütern, auf deren Export die deutsche Wirtschaft spezialisiert ist, politische Unsicherheit und strukturelle Veränderungen in der Automobilindustrie. Die Finanzpolitik stützt hingegen die gesamtwirtschaftliche Expansion. Für das kommende Jahr senken die Konjunkturforscher ebenfalls ihre Prognose auf 1,1% nach noch 1,8% im Frühjahr.

Enforcement of Banking Regulation and the Cost of Borrowing

Abstract
We show that borrowing firms benefit substantially from important enforcement actions issued on U.S. banks for safety and soundness reasons. Using hand-collected data on such actions from the main three U.S. regulators and syndicated loan deals over the years 1997–2014, we find that enforcement actions decrease the total cost of borrowing by approximately 22 basis points (or $4.6 million interest for the average loan). We attribute our finding to a competition-reputation effect that works over and above the lower risk of punished banks post-enforcement and survives in a number of sensitivity tests. We also find that this effect persists for approximately four years post-enforcement.
