Church Membership and Economic Recovery: Evidence from the 2005 Hurricane Season
Iftekhar Hasan, Stefano Manfredonia, Felix Noth
Economic Journal,

Abstract
This paper investigates the critical role of church membership in the process of economic recovery after high-impact natural disasters. We document a significant adverse treatment effect of the 2005 hurricane season in the Southeastern United States on establishment-level productivity. However, we find that establishments in counties with higher rates of church membership saw a significantly stronger recovery in terms of productivity for 2005–10. We also show that church membership is correlated with post-disaster entrepreneurship activities and population growth.

Forecast Combination and Interpretability Using Random Subspace

IWH Discussion Papers,
No. 21,
2024
Abstract
This paper investigates forecast aggregation via the random subspace regressions method (RSM) and explores the potential link between RSM and the Shapley value decomposition (SVD) using the US GDP growth rates. This technique combination enables handling high-dimensional data and reveals the relative importance of each individual forecast. First, it is possible to enhance forecasting performance in certain practical instances by randomly selecting smaller subsets of individual forecasts and obtaining a new set of predictions based on a regression-based weighting scheme. The optimal value of selected individual forecasts is also empirically studied. Then, a connection between RSM and SVD is proposed, enabling the examination of each individual forecast’s contribution to the final prediction, even when there is a large number of forecasts. This approach is model-agnostic (can be applied to any set of predictions) and facilitates understanding of how the aggregated prediction is obtained based on individual forecasts, which is crucial for decision-makers.

Sind Subventionen für Halbleiter zu rechtfertigen?
Reint E. Gropp, Alexander Reifschneider
Perspektiven der Wirtschaftspolitik,

Abstract
Reint Gropp und Alexander Reifschneider beleuchten in diesem Artikel die wichtigsten Argumente für und gegen die Subventionen, die im Rahmen des European Chips Acts für Halbleiter in Europa und in Deutschland geplant sind. Sie gehen dabei auch auf die geostrategischen Argumente ein. Es zeigt sich, dass die Subventionen für Produktionsanlagen für Halbleiter sehr schwer zu rechtfertigen sind. Subventionen für Forschung und Entwicklung statt für Produktion wären eine bessere Verwendung von Steuergeldern.

Organized Labor, Labor Market Imperfections, and Employer Wage Premia
Sabien Dobbelaere, Boris Hirsch, Steffen Müller, Georg Neuschäffer
ILR Review,
No. 3,
2024
Abstract
This article examines how collective bargaining through unions and workplace codetermination through works councils relate to labor market imperfections and how labor market imperfections relate to employer wage premia. Based on representative German plant data for the years 1999-2016, the authors document that 70% of employers pay wages below the marginal revenue product of labor and 30% pay wages above that level. Findings further show that the prevalence of wage markdowns is significantly smaller when organized labor is present, and that the ratio of wages to the marginal revenue product of labor is significantly larger. Finally, the authors document a close link between labor market imperfections and mean employer wage premia, that is, wage differences between employers corrected for worker sorting.
