Abstract
This study estimates the firm-level employment effects of investment grants in Germany. In addition to the average treatment effect on the treated, we examine discrimination in the funding rules as a potential source of effect heterogeneity. We combine a staggered difference-in-differences approach with a matching procedure at the cohort level. The findings reveal a positive effect of investment grants on employment development. The subsample analyses yield strong evidence for heterogeneous effects based on firm characteristics and the economic environment. They highlight the responsibility of the local funding authorities to clarify ex ante which goals of a funding programme are most important in their regions.

Individualism and the Formation of Human Capital
Katharina Hartinger, Sven Resnjanskij, Jens Ruhose, Simon Wiederhold
Journal of the European Economic Association,
forthcoming
Abstract
There is an ongoing debate about the economic effects of individualism. We establish that individualism leads to better educational and labor market outcomes. Using data from the largest international adult skill assessment, we identify the effects of individualism by exploiting variation between migrants at the origin country, origin language, and person level. Migrants from more individualistic cultures have higher cognitive skills and larger skill gains over time. They also invest more in their skills over the life-cycle, as they acquire more years of schooling and are more likely to participate in adult education activities. In fact, individualism is more important in explaining adult skill formation than any other cultural trait that has been emphasized in previous literature. In the labor market, more individualistic migrants earn higher wages and are less often unemployed. We show that our results cannot be explained by selective migration or omitted origin-country variables.

The Geography of Worker-Firm Sorting: Drivers of Rising Colocation
Nils Torben Hollandt, Steffen Müller
IWH Discussion Papers,
No. 22,
2025
Abstract
Spatial segregation of low- and high-wage workers is a persistent economic issue with broad social implications. Using social security data and an AKM wage decomposition, this paper examines spatial wage inequality in West Germany. Spatial inequality in log wages rose sharply between 1998 and 2008, mainly due to increased variance in worker pay premiums across regions (48%) and stronger positive spatial assortative matching of workers and establishments (40%), i.e. colocation. Changes in establishment wage premia are mostly unrelated to rising colocation whereas labor mobility even reduced it. Instead, growth in worker pay premiums among stayers was concentrated in regions where high-wage workers and high-wage establishments were overrepresented already in the 1990s and, thus, magnified pre-existing colocation leading to ‘colocation without relocation’. Germany’s rising trade surplus, especially with Eastern Europe, boosted stayers’ worker pay premiums in those ex-ante high-wage regions and fully explains rising colocation.

Schriftliche Anhörung des Finanzausschusses des Landtags Mecklenburg-Vorpommern
Welche Wachstumsimpulse können zusätzliche, kreditfinanzierte Finanzmittel für Infrastruktur, Klimaneutralität und Verteidigung in Mecklenburg-Vorpommern setzen? Im Rahmen einer schriftlichen Anhörung des Finanzausschusses des Landtages Mecklenburg-Vorpommern beantwortet das IWH Fragen zur Verwendung der Finanzmittel und zur möglichen Wirkung von zusätzlichen Investitionen auf das Produktionspotenzial und das Wirtschaftswachstum in Mecklenburg-Vorpommern. Angesichts der demographischen Entwicklung ist die Arbeitsproduktivität der Schlüssel zur Verbesserung der Wachstumsaussichten des Landes.

20 years after Hurricane Katrina: Church membership contributed significantly to economic recovery
Katrina and other hurricanes caused devastating damage in the south-east of the USA in the summer of 2005. A study by the Halle Institute for Economic Research (IWH) shows: in the years following the disaster, establishments in counties with higher rates of church membership saw a significantly stronger recovery in terms of productivity.

Corporate Loan Spreads and Economic Activity
Anthony Saunders, Alessandro Spina, Sascha Steffen, Daniel Streitz
Review of Financial Studies,
No. 2,
2025
Abstract
We use secondary corporate loan-market prices to construct a novel loan-market-based credit spread. This measure has considerable predictive power for economic activity across macroeconomic outcomes in both the U.S. and Europe and captures unique information not contained in public market credit spreads. Loan-market borrowers are compositionally different and particularly sensitive to supply-side frictions as well as financial frictions that emanate from their own balance sheets. This evidence highlights the joint role of financial intermediary and borrower balance-sheet frictions in understanding macroeconomic developments and enriches our understanding of which type of financial frictions matter for the economy.

Banks and the State-Dependent Effects of Monetary Policy
Martin S. Eichenbaum, Federico Puglisi, Sergio Rebelo, Mathias Trabandt
NBER Working Papers,
No. 33523,
2025
Abstract
We show that the response of banks’ net interest margin (NIM) to monetary policy shocks is state dependent. Following a period of low (high) Federal Funds rates, a contractionary monetary policy shock leads to an increase (decrease) in NIM. Aggregate economic activity exhibits a similar state-dependent pattern. To explain these dynamics, we develop a banking model in which social interactions influence households’ attentiveness to deposit interest rates. We embed that framework within a nonlinear heterogeneous-agent NK model. The estimated model accounts well quantitatively for our key empirical findings.
