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.

Disentangling Covid-19, Economic Mobility, and Containment Policy Shocks

IWH Discussion Papers,
Nr. 2,
2021
Abstract
We study the dynamic impact of Covid-19, economic mobility, and containment policy shocks. We use Bayesian panel structural vector autoregressions with daily data for 44 countries, identified through sign and zero restrictions. Incidence and mobility shocks raise cases and deaths significantly for two months. Restrictive policy shocks lower mobility immediately, cases after one week, and deaths after three weeks. Non-pharmaceutical interventions explain half of the variation in mobility, cases, and deaths worldwide. These flattened the pandemic curve, while deepening the global mobility recession. The policy tradeoff is 1 p.p. less mobility per day for 9% fewer deaths after two months.

Real Estate Transaction Taxes and Credit Supply

Deutsche Bundesbank Discussion Paper,
Nr. 4,

Abstract
We exploit staggered real estate transaction tax (RETT) hikes across German states to identify the effect of house price changes on mortgage credit supply. Based on approximately 33 million real estate online listings, we construct a quarterly hedonic house price index (HPI) between 2008:q1 and 2017:q4, which we instrument with state-speci c RETT changes to isolate the effect on mortgage credit supply by all local German banks. First, a RETT hike by one percentage point reduces HPI by 1.2%. This effect is driven by listings in rural regions. Second, a 1% contraction of HPI induced by an increase in the RETT leads to a 1.4% decline in mortgage lending. This transmission of fiscal policy to mortgage credit supply is effective across almost the entire bank capitalization distribution.

Privatpersonen erhöhen Ersparnisse aufgrund fehlender Ausgabemöglichkeiten und nicht aus Angst vor Arbeitslosigkeit
Während der Corona-Krise haben europäische Haushalte so viel Geld zurückgelegt wie noch nie. Eine Analyse des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH) führt dieses Sparverhalten hauptsächlich auf ein eingeschränktes Angebot infolge staatlicher Lockdown-Maßnahmen und nicht auf andere Faktoren wie ökonomische Unsicherheit zurück. IWH-Präsident Reint Gropp sieht daher Potenzial für eine rasche Wiederbelebung des Konsums und somit eine zügige wirtschaftliche Erholung, sobald der Lockdown aufgehoben wird.

Abstract
Die Corona-bedingte Wirtschaftskrise könnte den deutschen Bankensektor massiv in Mitleidenschaft ziehen, wenn die nationale und europäische Aufsicht nicht in den nächsten Monaten gegensteuert. Das ist die Aussage einer IWH-Studie, in der wir die Jahresabschlüsse von mehr als einer halben Million deutscher Unternehmen mit den Bilanzdaten von über 1 000 hiesigen Banken verknüpft haben. Die Stichprobe umfasst rund 90% der Bilanzsumme aller Banken und schließt alle großen systemrelevanten Geldhäuser mit ein. Wir benutzen dabei sektorspezifische Prognosen für die wirtschaftliche Entwicklung: Wir beziehen also die Tatsache mit ein, dass die Tourismusbranche besonders und die Baubranche relativ wenig von der Krise betroffen ist. Wir simulieren mehrere Szenarien: eines mit einer schnellen Erholung (V-förmig), eines mit einer relativ langsamen Erholung (U) und ein Szenario, in dem die Krise noch eine längere Zeit anhält (L).

Wages and the Value of Nonemployment
Simon Jäger, Benjamin Schoefer, Samuel Young, Josef Zweimüller
Quarterly Journal of Economics,
Nr. 4,
2020
Abstract
Nonemployment is often posited as a worker’s outside option in wage-setting models such as bargaining and wage posting. The value of nonemployment is therefore a key determinant of wages. We measure the wage effect of changes in the value of nonemployment among initially employed workers. Our quasi-experimental variation in the value of nonemployment arises from four large reforms of unemployment insurance (UI) benefit levels in Austria. We document that wages are insensitive to UI benefit changes: point estimates imply a wage response of less than $0.01 per $1.00 UI benefit increase, and we can reject sensitivities larger than $0.03. The insensitivity holds even among workers with low wages and high predicted unemployment duration, and among job switchers hired out of unemployment. The insensitivity of wages to the nonemployment value presents a puzzle to the widely used Nash bargaining model, which predicts a sensitivity of $0.24–$0.48. Our evidence supports wage-setting models that insulate wages from the value of nonemployment.

IWH warnt vor neuer Bankenkrise
Die Corona-Rezession könnte das Aus für dutzende Banken bundesweit bedeuten – selbst wenn Deutschland die Wirtschaftskrise glimpflich übersteht. Gefährdet sind vor allem viele Sparkassen und Genossenschaftsbanken, zeigt eine Analyse des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH). In den Bilanzen der betroffenen Geldinstitute stehen Kredite im dreistelligen Milliardenbereich. IWH-Präsident Gropp warnt vor einer möglichen hohen Zusatzlast für die ohnehin geschwächte Realwirtschaft.

Transmitting Fiscal Covid-19 Counterstrikes Effectively: Mind the Banks!

IWH Online,
Nr. 2,
2020
Abstract
The German government launched an unprecedented range of support programmes to mitigate the economic fallout from the Covid-19 pandemic for employees, self-employed, and firms. Fiscal transfers and guarantees amount to approximately €1.2 billion by now and are supplemented by similarly impressive measures taken at the European level. We argue in this note that the pandemic poses, however, also important challenges to financial stability in general and bank resilience in particular. A stable banking system is, in turn, crucial to ensure that support measures are transmitted to the real economy and that credit markets function seamlessly. Our analysis shows that banks are exposed rather differently to deteriorated business outlooks due to marked differences in their lending specialisation to different economic sectors. Moreover, a number of the banks that were hit hardest by bleak growth prospects of their borrowers were already relatively thinly capitalised at the outset of the pandemic. This coincidence can impair the ability and willingness of selected banks to continue lending to their mostly small and medium sized entrepreneurial customers. Therefore, ensuring financial stability is an important pre-requisite to also ensure the effectiveness of fiscal support measures. We estimate that contracting business prospects during the first quarter of 2020 could lead to an additional volume of non-performing loans (NPL) among the 40 most stressed banks ‒ mostly small, regional relationship lenders ‒ on the order of around €200 million. Given an initial stock of NPL of €650 million, this estimate thus suggests a potential level of NPL at year-end of €1.45 billion for this fairly small group of banks already. We further show that 17 regional banking markets are particularly exposed to an undesirable coincidence of starkly deteriorating borrower prospects and weakly capitalised local banks. Since these regions are home to around 6.8% of total employment in Germany, we argue that ensuring financial stability in the form of healthy bank balance sheets should be an important element of the policy strategy to contain the adverse real economic effects of the pandemic.
