European Firm Concentration and Aggregate Productivity
Tommaso Bighelli, Filippo di Mauro, Marc Melitz, Matthias Mertens
Abstract
This article derives a European Herfindahl-Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, European concentration rose due to a reallocation of economic activity towards large and concentrated industries. Over the same period, productivity gains from reallocation accounted for 50% of European productivity growth and markups stayed constant. Using country-industry variation, we show that changes in concentration are positively associated with changes in productivity and allocative efficiency. This holds across most sectors and countries and supports the notion that rising concentration in Europe reflects a more efficient market environment rather than weak competition and rising market power.

Globalisation in Europe: Consequences for the Business Environment and Future Patterns in Light of Covid-19
Sergio Inferrera
IWH-CompNet Discussion Papers,
No. 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.

Pandemie verzögert Aufschwung – Demografie bremst Wachstum
Dienstleistungsauftrag des Bundesministeriums für Wirtschaft und Energie,
No. 1,
2021
Abstract
Das erste Jahr der Corona-Pandemie stand in Deutschland im Zeichen extremer Schwankungen der ökonomischen Aktivität und einer massiven Lähmung der Binnenwirtschaft. Der kräftige Erholungsprozess nach dem Ende des Shutdowns im vergangenen Frühjahr kam im Zuge der zweiten Infektionswelle über das zurückliegende Winterhalbjahr insgesamt zum Erliegen, wobei es große Unterschiede zwischen Industrie und Dienstleistern gibt. Angesichts des aktuellen Infektionsgeschehens gehen die Institute davon aus, dass der derzeitige Shutdown zunächst fortgesetzt wird und die zuletzt erfolgten Lockerungen wieder weitgehend zurückgenommen werden. Erst ab Mitte des zweiten Quartals setzen Lockerungsschritte ein, die es den im Shutdown befindlichen Unternehmen erlauben, ihre Aktivitäten nach und nach wieder aufzunehmen. Bis zum Ende des dritten Quartals sollten dann alle Beschränkungen aufgehoben worden sein, weil bis dahin insbesondere mit einem weitreichenden Impffortschritt zu rechnen ist. Insgesamt dürfte das Bruttoinlandsprodukt in diesem Jahr um 3,7% zulegen. Die deutliche Erholung im zweiten Halbjahr 2021 wirkt sich auch erheblich auf die Jahresdurchschnittsrate für das Jahr 2022 aus, die nach vorliegender Prognose 3,9% beträgt.

International Emigrant Selection on Occupational Skills
Miguel Flores, Alexander Patt, Jens Ruhose, Simon Wiederhold
Journal of the European Economic Association,
No. 2,
2021
Abstract
We present the first evidence on the role of occupational choices and acquired skills for migrant selection. Combining novel data from a representative Mexican task survey with rich individual-level worker data, we find that Mexican migrants to the United States have higher manual skills and lower cognitive skills than nonmigrants. Results hold within narrowly defined region–industry–occupation cells and for all education levels. Consistent with a Roy/Borjas-type selection model, differential returns to occupational skills between the United States and Mexico explain the selection pattern. Occupational skills are more important to capture the economic motives for migration than previously used worker characteristics.

Who Benefits from Mandatory CSR? Evidence from the Indian Companies Act 2013
Jitendra Aswani, N. K. Chidambaran, Iftekhar Hasan
Emerging Markets Review,
March
2021
Abstract
We examine the value impact of mandatory Corporate Social Responsibility (CSR) spending required by the Indian Companies Act of 2013 for large and profitable Indian firms. We find that the external mandate is value decreasing, even after controlling for prior voluntary CSR activity by firms affected by the mandate. We also find that there is systematic crosssectional variation across firms. Firms that are profitable and firms in the Fast Moving Consumer Goods sector that voluntarily engaged in CSR, benefit from CSR. Industrial firms and firms with high capital expenditures are negatively impacted by the mandate. We conclude that a one-size-fits-all approach to CSR is sub-optimal and value decreasing.

New wave of infections suspends economic recovery
The lockdown is being eased only slightly in Germany in March 2021, and gross domestic product (GDP) declines significantly in the first quarter of 2021. As vaccination campaigns progress and restrictions are gradually eased, a normalisation of household consumption patterns will likely boost the economy later during the year. The Halle Institute for Economic Research (IWH) forecasts that GDP will increase by 3.7% in 2021, following a decline of 4.9% in 2020. In East Germany, both the contraction and the rebound are much less pronounced.

Private Equity in the Hospital Industry
Janet Gao, Yongseok Kim, Merih Sevilir
ECGI Working Paper,
No. 787,
2021
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.

Much more bankruptcies expected than currently observed in Germany
In a recession, the number of bankruptcies usually increases with some delay. However, despite the corona crisis, the number of bankruptcies in Germany is lower than predicted based on the long-term trend. The state aid packages and the suspension of the insolvency rules have led to fewer bankruptcies than expected. The Halle Institute for Economic Research (IWH) has estimated how many bankruptcies would actually have been likely to occur by industry because of the corona recession if the typical economic pattern had been in place. The results indicate that after the end of the state aid and exception rules bankruptcies are likely to pick up.

The Viral Effects of Foreign Trade and Supply Networks in the Euro Area
Virginia di Nino, Bruno Veltri
IWH-CompNet Discussion Papers,
No. 4,
2020
Abstract
Containment measures of COVID-19 have generated a chain of supply and demand shocks around the globe with heterogeneous fallout across industries and countries. We quantify their transmission via foreign trade with a focus on the euro area where deep firms integration within regional supply chains and strong demand linkages act as a magnification mechanism. We estimate that spillover effects in the euro area from suppression measures in one of the five main euro area countries range between 15-28% the size of the original shock; negative foreign demand shocks depress euro area aggregate activity by about a fifth the size of the external shock and a fourth of the total effect is due to indirect propagation through euro area supply chain. Last, reopening to regional tourism softened the contraction of aggregate activity due to travel and tourism bans by about a third in the euro area. Our findings suggest that enhanced coordination of recovery plans would magnify their beneficial effects.
