IWH-Flash-Indikator I. Quartal und II. Quartal 2021

Katja Heinisch, Oliver Holtemöller, Axel Lindner, Birgit Schultz
IWH-Flash-Indikator, Nr. 1, 2021
Abstract
Seit November 2020 befindet sich Deutschland im Lockdown. Dadurch konnte sich der Erholungskurs der deutschen Wirtschaft im vierten Quartal nicht weiter fortsetzen, und das Bruttoinlandsprodukt (BIP) stagnierte mit 0,1% nahezu. Durch die Mitte Dezember weiter verschärften Eindämmungsmaßnahmen wird die wirtschaftliche Aktivität in vielen Branchen im laufenden Quartal erschwert oder gänzlich verhindert. Auch ein weiteres Sinken der Anzahl der Covid-19-Infizierten dürfte daran so schnell nichts ändern, da die Furcht vor hochinfektiösen Corona-Mutationen groß ist. Ebenfalls versprechen die mittlerweile zugelassenen Impfstoffe gegen Covid-19-Erkrankungen keine kurzfristige Verbesserung der Situation, da sie wohl frühestens in einigen Monaten für die breite Masse der Bevölkerung verfügbar sein werden. Aufgrund der robusten Nachfrage aus dem Ausland dürfte die Wirtschaftsleistung laut IWH-Flash-Indikator jedoch im ersten Quartal 2021 nur um 0,7% zurückgehen und im zweiten Quartal, wenn die Corona-Eindämmungsmaßnahmen langsam zurückgeführt werden sollten, um 1,5% steigen. (vgl. Abbildung 1).

Selbständigkeit nach der Wiedervereinigung

Matthias Brachert
In: Dossier "Lange Wege der Deutschen Einheit", Bundeszentrale für politische Bildung, 2021
Abstract
Die Zahl der Selbstständigen in Ostdeutschland (ohne Berlin) beläuft sich derzeit auf rund 600 000 und ist das Ergebnis eines über die Jahre zunehmenden Trends. Selbständigkeit wurde in der DDR kaum ein Platz eingeräumt. Zum Zeitpunkt der Wiedervereinigung besaß Ostdeutschland eine Selbständigenquote von nur rund 2,2 Prozent. Dieser Anteil hat sich 2018 auf 9,2 Prozent erhöht. Damit übersteigt die Selbständigenquote Ostdeutschlands diejenige Westdeutschlands seit dem Jahr 2013. Es gilt hierbei jedoch zu beachten, dass das Wachstum der Selbständigenanzahl insbesondere in Ostdeutschland von den Solo-Selbstständigen getragen war. Zudem bestehen im Hinblick auf die sektorale Zusammensetzung mit einem geringeren Anteil an wissensintensiven Wirtschaftszweigen als in Westdeutschland noch Unterschiede zwischen Ost- und Westdeutschland.

A Note of Caution on Quantifying Banks' Recapitalization Effects

Felix Noth, Kirsten Schmidt, Lena Tonzer
Deutsche Bundesbank Discussion Paper, Nr. 2, 2021
publiziert in: Journal of Money, Credit and Banking
Abstract
Unconventional monetary policy measures like asset purchase programs aim to reduce certain securities' yield and alter financial institutions' investment behavior. These measures increase the institutions' market value of securities and add to their equity positions. We show that the extent of this recapitalization effect crucially depends on the securities' accounting and valuation methods, country-level regulation, and maturity structure. We argue that future research needs to consider these factors when quantifying banks' recapitalization effects and consequent changes in banks' lending decisions to the real sector.

The Appropriateness of the Macroeconomic Imbalance Procedure for Central and Eastern European Countries

Geraldine Dany-Knedlik, Martina Kämpfe, Tobias Knedlik
Empirica, Nr. 1, 2021
Abstract
The European Commission’s Scoreboard of Macroeconomic Imbalances is a rare case of a publicly released early warning system. It was published first time in 2012 by the European Commission as a reaction to public debt crises in Europe. So far, the Macroeconomic Imbalance Procedure takes a one-size-fits-all approach with regard to the identification of thresholds. The experience of Central and Eastern European Countries during the global financial crisis and in the resulting public debt crises has been largely different from that of other European countries. This paper looks at the appropriateness of scoreboard of the Macroeconomic Imbalances Procedure of the European Commission for this group of catching-up countries. It is shown that while some of the indicators of the scoreboard are helpful to predict crises in the region, thresholds are in most cases set too narrow since it largely disregarded the specifics of catching-up economies, in particular higher and more volatile growth rates of various macroeconomic variables.

Insolvenzen in der Corona-Krise

Steffen Müller
IWH Policy Notes, Nr. 2, 2021
Abstract
Die Insolvenzzahlen sind trotz Corona-Krise im Jahr 2020 stark gesunken. Diese paradoxe Situation kann in erster Linie durch staatliche Unterstützungsmaßnahmen und abwartendes Verhalten bei den Unternehmen erklärt werden. Die Krise traf die meisten Unternehmen am Ende einer langanhaltenden wirtschaftlichen Boomphase und somit haben viele Unternehmen umfangreiche Reserven aufgebaut, die sie in Erwartung eines Nach-Corona Booms aufbrauchen. Obwohl eine Insolvenzwelle ab Frühjahr nicht auszuschließen ist, ist sie doch eher unwahrscheinlich. Der Staat muss seine Kräfte bündeln um ein Wiederaufflammen der Pandemie nach dem Sommer 2021 zu verhindern und gleichzeitig die Stützungsmaßnahmen bereits im Jahr 2021 beenden, um eine „Zombifizierung“ der Wirtschaft zu unterbinden.

Do Household Wealth Shocks Affect Productivity? Evidence From Innovative Workers During the Great Recession

Shai B. Bernstein, Richard R. Townsend, Timothy McQuade
Journal of Finance, Nr. 1, 2021
Abstract
We investigate how the deterioration of household balance sheets affects worker productivity, and in turn economic downturns. Specifically, we compare the output of innovative workers who experienced differential declines in housing wealth during the financial crisis but were employed at the same firm and lived in the same metropolitan area. We find that, following a negative wealth shock, innovative workers become less productive and generate lower economic value for their firms. The reduction in innovative output is not driven by workers switching to less innovative firms or positions. These effects are more pronounced among workers at greater risk of financial distress.

Do Digital Information Technologies Help Unemployed Job Seekers Find a Job? Evidence from the Broadband Internet Expansion in Germany

Nicole Gürtzgen, André Diegmann, Laura Pohlan, Gerard J. van den Berg
European Economic Review, February 2021
Abstract
This paper studies effects of the introduction of a new digital mass medium on reemployment of unemployed job seekers. We combine data on broadband internet availability at the local level with German individual register data. We address endogeneity by exploiting technological peculiarities that affected the roll-out of broadband internet. Results show that broadband internet improves reemployment rates after the first months in unemployment for males. Complementary analyses with survey data suggest that internet access mainly changes male job seekers’ search behavior by increasing online search and the number of job applications.

Why Are Households Saving so much During the Corona Recession?

Reint E. Gropp, William McShane
IWH Policy Notes, Nr. 1, 2021
Abstract
Savings rates among European households have reached record levels during the Corona recession. We investigate three possible explanations for the increase in household savings: precautionary motivations induced by increased economic uncertainty, reduced consumption opportunities due to lockdown measures, and Ricardian Equivalence, i.e. increases in the expected future tax-burden of households driven by increases in government debt. To test these explanations, we compile a monthly panel of euro area countries from January 2019 to August 2020. Our findings indicate that the chief driver of the increase in household savings is supply: As governments restrict households’ opportunities to spend, households spend less. We estimate that going from no lockdown measures to that of Italy’s in March, would have resulted in the growth of Germany’s deposit to Gross Domestic Product (GDP) ratio being 0.6 percentage points higher each month. This would be equivalent to the volume of deposits increasing by roughly 14.3 billion euros or 348 euros per house monthly. Demand effects, driven by either fears of unemployment or fear of infection from COVID-19, appear to only have a weak impact on household savings, whereas changes in government debt are unrelated or even negatively related to savings rates. The analysis suggests that there is some pent-up demand for consumption that may unravel after lockdown measures are abolished and may result in a significant increase in consumption in the late spring/early summer 2021.

Can Mentoring Alleviate Family Disadvantage in Adolescence? A Field Experiment to Improve Labor-Market Prospects

Sven Resnjanskij, Jens Ruhose, Simon Wiederhold, Ludger Woessmann
CESifo Working Paper, Nr. 8870, 2021
publiziert in: Journal of Political Economy
Abstract

We study a mentoring program that aims to improve the labor-market prospects of school-attending adolescents from disadvantaged families by offering them a university-student mentor. Our RCT investigates program effectiveness on three outcome dimensions that are highly predictive of adolescents later labor-market success: math grades, patience-social skills, and labor-market orientation. For low-SES adolescents, the one-to-one mentoring increases a combined index of the outcomes by half a standard deviation after one year, with significant increases in each dimension. Part of the treatment effect is mediated by establishing mentors as attachment figures who provide guidance for the future. The mentoring is not effective for higher-SES adolescents. The results show that substituting lacking family support by other adults can help disadvantaged children at adolescent age.

Private Equity in the Hospital Industry

Janet Gao, Yongseok Kim, Merih Sevilir
ECGI Working Paper, Nr. 787, 2021
publiziert in: Journal of Financial Economics
Abstract

We examine employment and patient outcomes at hospitals acquired by private equity (PE) firms and PE-backed hospitals. While employment declines at PE-acquired hospitals, core medical workers (physicians, nurses, and pharmacists) increase significantly. The proportion of wages paid to core workers increases at PE-acquired hospitals whereas the proportion paid to administrative employees declines. These results are most pronounced for deals where the acquirers are publicly traded PE-backed hospitals. Non-PE-backed acquirers also cut employment but do not increase core workers or reduce administrative expenditures. Finally, PE-backed acquirers are not associated with worse patient satisfaction or mortality rates compared to their non-PE-backed counterparts.
