Abstract
This paper examines how firms’ exposure to supply chain disruptions (SCD) affects firm outcomes in the European Union (EU). Exploiting heterogeneous responses to workplace closures imposed by sourcing countries during the pandemic as a shock to SCD, we provide empirical evidence that firms in industries relying more heavily on foreign inputs experience a significant decline in sales compared to other firms. We document that external finance, particularly bank financing, plays a critical role in mitigating the effects of SCD. Furthermore, we highlight the unique importance of bank loans for small and solvent firms. Our findings also indicate that highly diversified firms and those sourcing inputs from less distant partners are less vulnerable to SCD.

Abstract
This Technical Report documents the construction and coverage of the IWH European Real Estate Index (EREI). Since 2018, we have used machine-learning methods to collect monthly listings of residential real estate available for sale or rent in up to 20 European countries. The Technical Report documents the cleaning and selection process and describes the data regarding coverage, moments, and frequencies to construct the EREI.

„Evaluation der Gemeinschaftsaufgabe ‚Verbesserung der regionalen Wirtschaftsstruktur‘ (GRW)“ durch einzelbetriebliche Erfolgskontrolle – Evaluationsbericht –

Abstract
Gegenstand dieses Evaluationsberichts ist die Replikation und Erweiterung der Ergebnisse des vorhergehenden Gutachtens zur Evaluation der Gemeinschaftsaufgabe ‚Verbesserung der regionalen Wirtschaftsstruktur‘ (GRW)
Der vorliegende Evaluationsbericht verfolgt zwei Ziele. Erstens aktualisiert er die Ergebnisse aus dem vorherigen Gutachten. Zweitens betrachtet er einige Aspekte zu den Wirkungen der GRW-Förderung vertiefend. Dazu gehört insbesondere die Frage, ob die GRW für die geförderten Betriebe tatsächlich einen Anreizeffekt im Sinne einer Ausweitung der Investitionstätigkeit hatte und wie sich die Effekte der Förderung unter Verwendung fortgeschrittener Produktivitätsmaße darstellt. Des Weiteren widmet sich der Evaluationsbericht einer vertiefenden Untersuchung heterogener Effekte auf sektoral disaggregierter Ebene sowie nach Betriebsgrößenklassen. Wo es möglich ist, analysiert der Bericht zudem längere Zeiträume nach dem Beginn des Förderprojekts. Schließlich widmet sich der Evaluationsbericht Fragen zur Wirtschaftlichkeit des GRW-Programms auf einzelbetrieblicher Ebene, indem er die Effekte in Beziehung setzt zur Höhe der aufgewendeten Fördermittel.

Declining Business Dynamism in Europe: The Role of Shocks, Market Power, and Technology

2024
Abstract
We study changes in business dynamism in Europe after 2000 using novel micro-aggregated data that we collected for 19 European countries. In all countries, we document a broad-based decline in job reallocation rates that concerns most economic sectors and size classes. This decline is mainly driven by dynamics within sectors, size, and age classes rather than by compositional changes. Large and mature firms experience the strongest decline in job reallocation rates. Simultaneously, the employment shares of young firms decline. Consistent with US evidence, firms’ employment has become less responsive to productivity shocks. However, the dispersion of firms’ productivity shocks has decreased too. To enhance our understanding of these patterns, we derive and apply a novel firm-level framework that relates changes in firms’ sales, market power, wages, and production technology to firms’ responsiveness and job reallocation.

Out of Sight, out of Mind: Divestments and the Global Reallocation of Pollutive Assets
Tobias Berg, Lin Ma, Daniel Streitz
SSRN Working Papers,
2023
Abstract
Large emitters reduced their carbon emissions by around 11-15% after the 2015 Paris Agreement (“the Agreement”) relative to public firms that are less in the limelight. We show that this effect is predominantly driven by divestments. Large emitters are 9 p.p. more likely to divest pollutive assets in the post-Agreement period, an increase of over 75%. This divestment effect comes from asset sales and not from closures of pollutive facilities. There is no evidence for increased engagements in other emission reduction activities. Our results indicate significant global asset reallocation effects after the Agreement, shifting emissions out of the limelight.
