Abstract
We extend the canonical epidemiology model to study the interaction between economic decisions and epidemics. Our model implies that people cut back on consumption and work to reduce the chances of being infected. These decisions reduce the severity of the epidemic but exacerbate the size of the associated recession. The competitive equilibrium is not socially optimal because infected people do not fully internalize the effect of their economic decisions on the spread of the virus. In our benchmark model, the best simple containment policy increases the severity of the recession but saves roughly half a million lives in the United States.

COVID-19 Financial Aid and Productivity: Has Support Been Well Spent?

Bruegel-Policy Contributions,
Nr. 21,

Abstract
Most European Union countries have made good progress with vaccinating their populations against COVID-19 and are now seeing a rebound in economic activity. While the scarring effects of the crisis and the long-term implications of the pandemic are only partially understood, the effects of support given to firms can be evaluated in order to help plan the removal of crisis support. An analysis of France, Germany and Italy shows the potential for ‘cleansing effects’ in that it was the least-productive firms that have been affected most by the crisis. While support was generally not targeted at protecting good firms only, financial support went by and large to those with the capacity to survive and succeed. Labour schemes have been effective in protecting employment.

How Can Macroprudential Policies Transmit Within a Banking Group?

WorldBank All About Finance,
2021
Abstract
The unexpected shock represented by the COVID-19 pandemic illustrates the importance of building robust macroprudential frameworks to increase countries’ resilience against sudden disruptions in financial markets. By now, a widespread opinion among commentators and policy makers is that the macroprudential frameworks that were implemented over the past decades were effective in moderating market stress, a view supported by ample evidence on the effectiveness of macroprudential policies.

A Comparison of Monthly Global Indicators for Forecasting Growth
Christiane Baumeister, Pierre Guérin
International Journal of Forecasting,
Nr. 3,
2021
Abstract
This paper evaluates the predictive content of a set of alternative monthly indicators of global economic activity for nowcasting and forecasting quarterly world real GDP growth using mixed-frequency models. It shows that a recently proposed indicator that covers multiple dimensions of the global economy consistently produces substantial improvements in forecasting accuracy, while other monthly measures have more mixed success. Specifically, the best-performing model yields impressive gains with MSPE reductions of up to 34% at short horizons and up to 13% at long horizons relative to an autoregressive benchmark. The global economic conditions indicator also contains valuable information for assessing the current and future state of the economy for a set of individual countries and groups of countries. This indicator is used to track the evolution of the nowcasts for the U.S., the OECD area, and the world economy during the COVID-19 pandemic and the main factors that drive the nowcasts are quantified.

Inequality in Life and Death
Martin S. Eichenbaum, Sergio Rebelo, Mathias Trabandt
Abstract
We argue that the Covid epidemic disproportionately affected the economic well-being and health of poor people. To disentangle the forces that generated this outcome, we construct a model that is consistent with the heterogeneous impact of the Covid recession on low- and high-income people. According to our model, two thirds of the inequality in Covid deaths reflect pre-existing inequality in comorbidity rates and access to quality health care. The remaining third, stems from the fact that low-income people work in occupations where the risk of infection is high. Our model also implies that the rise in income inequality generated by the Covid epidemic reflects the nature of the goods that low-income people produce. Finally, we assess the health-income trade-offs associated with fiscal transfers to the poor and mandatory containment policies.

Einsam durch die Pandemie – soziale Isolierung erhöht Bereitschaft zu egoistischem Verhalten
Die soziale Distanzierung als Maßnahme gegen die COVID-19-Pandemie hat weitreichende gesellschaftliche Folgen, die aus ökonomischer Perspektive bislang kaum diskutiert wurden. Dies geht aus einer Untersuchung des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH) hervor. „Die Erfahrung der sozialen Isolierung führte dazu, dass die Teilnehmenden unserer Studie eher egoistische Entscheidungen treffen“, sagt Studienautorin Sabrina Jeworrek, Juniorprofessorin an der Otto-von-Guericke-Universität Magdeburg und Forschungsgruppenleiterin in der Abteilung Strukturwandel und Produktivität am IWH.

Alone at Home: The Impact of Social Distancing on Norm-consistent Behavior
Sabrina Jeworrek, Joschka Waibel
IWH Discussion Papers,
Nr. 8,
2021
Abstract
Around the globe, the COVID-19 pandemic has turned daily live upside down since social distancing is probably the most effective means of containing the virus until herd immunity is reached. Social norms have been shown to be an important determinant of social distancing behaviors. By conducting two experiments and using the priming method to manipulate social isolation recollections, we study whether social distancing has in turn affected norms of prosociality and norm compliance. The normative expectations of what behaviors others would approve or disapprove in our experimental setting did not change. Looking at actual behavior, however, we find that persistent social distancing indeed caused a decline in prosociality – even after the relaxation of social distancing rules and in times of optimism. At the same time, our results contain some good news since subjects seem still to care for norms and become more prosocial once again after we draw their attention to the empirical norm of how others have previously behaved in a similar situation.

Globalisation in Europe: Consequences for the Business Environment and Future Patterns in Light of Covid-19
Sergio Inferrera
IWH-CompNet Discussion Papers,
Nr. 2,
2021
Abstract
In this paper, I study the consequences of globalisation, as measured by the involvement of firms in GVC, on the business environment. In particular, I focus on concentration and productivity, firstly by estimating robust elasticities and then isolating the exogenous component of the variation in the participation in GVC. To this aim, I exploit the distance between industries in terms of upstreamness and downstreamness along the supply chain. The evidences suggest that involvement in international supply chains is positively related to concentration at the sector level and positively associated with aggregate productivity, an effect that is driven by the firms at the top of the productivity distribution. Finally, I relate these findings to the current pandemic, going beyond the lack of official statistics and estimating GVC participation for 2020 at the country-level through real time world-seaborne trade data, providing evidences on the re-absorption of the Covid shock in several European economies.

Wirtschaftliche Mobilität dürfte nach Lockerung deutlich steigen – aber auch die Zahl der COVID-19-Fälle
Die Lockerung der Corona-Eindämmungsmaßnahmen von Anfang März 2021 führen zu einem deutlichen Anstieg der wirtschaftlichen Mobilität und ermöglichen wieder mehr persönliche Kontakte in Deutschland. Schätzungen deuten darauf hin, dass der zu erwartende Anstieg der ökonomischen Mobilität mehr als zehn Prozentpunkte betragen kann. Dies dürfte die Zahl der Neuinfektionen und der Todesfälle in Deutschland um 25% erhöhen. Da sowohl ein fortgesetzter Lockdown als auch Lockerungen erhebliche negative Konsequenzen mit sich bringen, ist es umso wichtiger, durch eine bessere Test- und Quarantänestrategie und durch eine höhere Geschwindigkeit beim Impfen weitere Lockerungen zu ermöglichen, ohne damit die Gesundheit der Menschen zu gefährden.

Wirtschaftliche Mobilität dürfte nach Lockerung deutlich steigen – aber auch die Zahl der COVID-19-Fälle

Nr. 3,
2021
Abstract
In Deutschland wurden Anfang März in einigen Bereichen Maßnahmen zur Eindämmung des Coronavirus gelockert; so wurde die Anzahl der Personen aus verschiedenen Haushalten, die sich treffen dürfen, vielerorts erhöht und Einzelhandelsgeschäfte können vermehrt wieder Kunden empfangen. Auf diese Weise kommt es zu einem gewollten Wiederanstieg der wirtschaftlichen Mobilität und der persönlichen Kontakte zwischen Menschen. Die Kontakthäufigkeit ist allerdings auch ein wesentlicher Einflussfaktor für die Ausbreitungsgeschwindigkeit des Coronavirus, zumal die Lockerungen bislang nicht mit einer systematischen Teststrategie einhergehen; und auch der Impffortschritt bleibt hinter den Erwartungen zurück. Schätzungen auf Basis eines Modells für den Zusammenhang zwischen Eindämmungsmaßnahmen (Oxford COVID-19 Government Response Tracker, Stringency Index), wirtschaftlicher Mobilität (Google Mobility Data), Corona-Neuinfektionen und Todesfällen mit Daten aus 44 Ländern deuten darauf hin, dass die jüngsten Lockerungen die wirtschaftliche Mobilität um mehr als zehn Prozentpunkte ansteigen lassen und die Zahl der Neuinfektionen und der Todesfälle in Deutschland um 25% erhöhen. Da sowohl ein fortgesetzter Lockdown als auch Lockerungen erhebliche negative Konsequenzen mit sich bringen, ist es umso wichtiger, durch eine bessere Test- und Quarantänestrategie und durch eine höhere Geschwindigkeit beim Impfen weitere Lockerungen zu ermöglichen, ohne damit die Gesundheit der Menschen zu gefährden.
