Unions as Insurance: Workplace Unionization and Workers' Outcomes During COVID-19
Nils Braakmann, Boris Hirsch
Industrial Relations: A Journal of Economy and Society,
forthcoming
Abstract
Abstract We investigate to what extent workplace unionization protects workers from external shocks by preventing involuntary job separations. Using the COVID-19 pandemic as a plausibly exogenous shock hitting the whole economy, we compare workers who worked in unionized and non-unionized workplaces directly before the pandemic in a difference-in-differences framework. We find that unionized workers were substantially more likely to remain working for their pre-COVID employer and to be in employment. This greater employment stability was not traded off against lower working hours or labor income.

Risk in the banking sector: four out of ten top supervisors come from the financial industry
Europe's banks realise excess returns on the stock market when their alumni join the boards of national supervisory authorities. A study by the Halle Institute for Economic Research (IWH) shows that this happens more frequently than previously recognised. The findings indicate a risk to financial stability and call for a more merit-based, transparent appointment of senior regulators.

A Congestion Theory of Unemployment Fluctuations
Yusuf Mercan, Benjamin Schoefer, Petr Sedláček
American Economic Journal: Macroeconomics,
No. 1,
2024
Abstract
We propose a theory of unemployment fluctuations in which newhires and incumbentworkers are imperfect substitutes. Hence, attempts to hire away the unemployed during recessions diminish the marginal product of new hires, discouraging job creation. This single feature achieves a ten-fold increase in the volatility of hiring in an otherwise standard search model, produces a realistic Beveridge curve despite countercyclical separations, and explains 30–40% of U.S. unemployment fluctuations. Additionally, it explains the excess procyclicality of new hires’ wages, the cyclical labor wedge, countercyclical earnings losses from job displacement, and the limited steady-state effects of unemployment insurance.

Entwicklung der öffentlichen Gesundheitsausgaben
Götz Zeddies
Wirtschaftsdienst,
No. 6,
2023
Abstract
Die sozialen Sicherungssysteme in Deutschland basieren auf dem Umlageverfahren, bei dem die Ausgaben der Sozialversicherungen in der laufenden Periode durch Einnahmen aus Beiträgen, die auf die Einkommen der abhängig Beschäftigten erhoben werden, gedeckt werden. Vor dem Hintergrund des demografischen Wandels, der in den kommenden Jahren immer stärker zum Tragen kommen wird, wird häufig die Nachhaltigkeit der umlagefinanzierten sozialen Sicherungssysteme hinterfragt, weil sich das Verhältnis von Beitragszahlern und Leistungsempfängern ändern wird. Dies dürfte sich zwar vor allem bei der gesetzlichen Rentenversicherung auswirken, aber auch bei der gesetzlichen Kranken- und der Pflegeversicherung.

Analysis of earnings calls: Blathering managers harm their company
If a senior executive refuses to give information to professional investors, the company's stock market value drops afterwards. This is shown in a study by the Halle Institute for Economic Research (IWH) after evaluating
1.2 million answers from tele-phone conferences.

Natural Disasters and Bank Stability: Evidence from the U.S. Financial System
Felix Noth, Ulrich Schüwer
Journal of Environmental Economics and Management,
May
2023
Abstract
We show that weather-related natural disasters in the United States significantly weaken the financial stability of banks with business activities in affected regions. This is reflected in higher probabilities of default, lower z-scores, higher non-performing assets ratios, higher foreclosure ratios, lower returns on assets and lower equity ratios of affected banks in the years following a natural disaster. The effects are economically relevant and highlight the financial vulnerability of banks and their borrowers despite insurances and public aid programs.
