Gemeinschaftsdiagnose: Pandemic Delays Upswing — Demography Slows Growth
Oliver Holtemöller, Stefan Kooths, Claus Michelsen, Torsten Schmidt, Timo Wollmershäuser
Wirtschaftsdienst,
May
2021
Abstract
In Germany, the first year of the coronavirus pandemic was characterised by extreme fluctuations in economic activity and a massively paralysed domestic economy. In their spring report, the leading economic research institutes assume that the current shutdown will continue and gradually be lifted from mid-May until the end of the third quarter. In the wake of the easing, private consumption in particular will recover strongly. Overall, GDP is expected to grow by 3.7 % this year and 3.9 % next year.

Economic Mobility Likely to Increase Significantly after Relaxation – but also Number of COVID-19 Cases
Oliver Holtemöller, Malte Rieth
IWH Policy Notes,
No. 3,
2021
Abstract
In Germany, measures to contain the coronavirus were relaxed in some areas at the beginning of March; in many places, for example, the restrictions on private and public gatherings were eased, and retail stores are increasingly able to receive customers again. The aim of these decisions is to allow for more economic mobility and personal contact between people. However, the frequency of contact is a major factor influencing the rate at which the coronavirus spreads, especially since the relaxations have so far not been accompanied by a systematic testing strategy; and vaccination progress has so far also fallen short of expectations. Estimates based on a model of the relationship between containment measures (Oxford COVID-19 Government Response Tracker, Stringency Index), economic mobility (Google Mobility Data), new corona infections, and deaths with data from 44 countries suggest that the recent relaxations increase economic mobility by ten percentage points and the number of new infections and deaths in Germany by 25%. Because both continued lockdown and relaxations have significant negative consequences, it is even more important to enable further relaxations through better testing and quarantine strategies and by increasing the pace of vaccination without putting people's health at risk.

Disentangling Covid-19, Economic Mobility, and Containment Policy Shocks
Annika Camehl, Malte Rieth
IWH Discussion Papers,
No. 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.

Unternehmensinsolvenzen in Deutschland im Zuge der Corona-Krise
Oliver Holtemöller
Wirtschaft im Wandel,
No. 1,
2021
Abstract
Die Corona-Pandemie hat die deutsche Wirtschaft in eine tiefe Rezession getrieben. In diesem Beitrag wird analysiert, wie sich die Rezession in den Unternehmensinsolvenzen niederschlägt. Prognosen auf Basis des üblichen Zusammenhangs zwischen Bruttowertschöpfung und Unternehmensinsolvenzen nach Wirtschaftsbereichen deuten auf eine kräftige Zunahme der Unternehmensinsolvenzen im zweiten Halbjahr 2020 hin. Für Unternehmensinsolvenzen gelten allerdings seit März 2020 Ausnahmeregelungen, die das Ziel haben, allein durch die Corona-Krise bedingte Unternehmensinsolvenzen zu vermeiden. Ferner erhalten die Unternehmen finanzielle Unterstützung im Rahmen der Corona-Hilfspakete. Mit zunehmender Dauer der wirtschaftlichen Beeinträchtigungen nimmt die Wahrscheinlichkeit von Unternehmensinsolvenzen gleichwohl zu, sodass nach Aufhebung der Ausnahmeregelungen Insolvenzen nachgeholt werden dürften und das übliche konjunkturelle Muster wieder greift.

(Since when) are East and West German Business Cycles Synchronised?
Stefan Gießler, Katja Heinisch, Oliver Holtemöller
Jahrbücher für Nationalökonomie und Statistik,
No. 1,
2021
Abstract
We analyze 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 we 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, synchronisation among East and West German business cycles seems to have become weaker again recently.

Changing Business Dynamism and Productivity: Shocks versus Responsiveness
Ryan A. Decker, John Haltiwanger, Ron S. Jarmin, Javier Miranda
American Economic Review,
No. 12,
2020
Abstract
The pace of job reallocation has declined in the United States in recent decades. We draw insight from canonical models of business dynamics in which reallocation can decline due to (i) lower dispersion of idiosyncratic shocks faced by businesses, or (ii) weaker marginal responsiveness of businesses to shocks. We show that shock dispersion has actually risen, while the responsiveness of business-level employment to productivity has weakened. Moreover, declining responsiveness can account for a significant fraction of the decline in the pace of job reallocation, and we find suggestive evidence this has been a drag on aggregate productivity.

Financial Technologies and the Effectiveness of Monetary Policy Transmission
Iftekhar Hasan, Boreum Kwak, Xiang Li
IWH Discussion Papers,
No. 26,
2020
Abstract
This study investigates whether and how financial technologies (FinTech) influence the effectiveness of monetary policy transmission. We use an interacted panel vector autoregression model to explore how the effects of monetary policy shocks change with regional-level FinTech adoption. Results indicate that FinTech adoption generally mitigates monetary policy transmission to real GDP, consumer prices, bank loans, and housing prices. A subcategorical analysis shows that the muted transmission is the most pronounced in the adoption of FinTech payment and credit, compared to that of insurance. The regulatory arbitrage and competition between FinTech and banks are the possible mechanisms leading a mitigated monetary policy transmission.

Public Bank Guarantees and Allocative Efficiency
Reint E. Gropp, Andre Guettler, Vahid Saadi
Journal of Monetary Economics,
December
2020
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.
