Abstract
We assemble data about executives on the boards of national supervisory authorities (NSA) in European banking, which reveal that 40% have an employment history in the financial industry. Appointment patterns to NSA boards differ substantially across countries. Generally, the appointment of former finance professionals as prudential supervisors is inconsequential for banks‘ valuations, capitalization, and asset growth. The exception are positive, but short-lived valuation effects for those banks whose alumni are appointed as executives of directly responsible NSA boards. Circumstantial evidence suggests that a “proximity bias“ is a more likely driver of this effect inste

Mixing QE and Interest Rate Policies at the Effective Lower Bound: Micro Evidence from the Euro Area
Christian Bittner, Alexander Rodnyansky, Farzad Saidi, Yannick Timmer
Review of Finance,
forthcoming
Abstract
We study the interaction of expansionary rate-based monetary policy and quantitative easing, despite their concurrent implementation, by exploiting heterogeneous banks and the introduction of negative monetary-policy rates in a fragmented euro area. Quantitative easing increases credit supply less, translating into weaker employment growth, when banks’ funding costs do not decrease. Using administrative data from Germany, we uncover that among banks selling their securities, central-bank reserves remain disproportionately with high-deposit banks that are constrained due to sticky customer deposits at the zero lower bound. Affected German banks lend relatively less to firms while increasing their interbank exposure in the euro area.

Safety in Unemployment and Risky Experimentation of Young Firms
Renato Faccini, Seho Kim, Javier Miranda
IWH Discussion Papers,
No. 15,
2026
Abstract
We develop a theory in which a lower cost of job loss reduces the compensating wage premium workers require to join risky young firms. Lower labor costs encourage high-upside experimentation and raise productivity. Because experimentation is not directly observable, we exploit its life-cycle structure: experimentation risk is concentrated among young firms and resolved as firms mature. Using Danish matched employer-employee data and labor-market variation, we show that higher job-finding rates are associated with a lower young-mature wage differential. A randomized survey experiment supports the mechanism: worsening unemployment prospects increases the premium workers require to accept employment at higher-failure-risk young firms.

Joint Economic Forecast Autumn 2026: Recovery under structural stress – fiscal policy on slippery ground
The German economy has been recovering since the end of 2025. This recovery, although stronger than expected in spring, remains modest. The leading economic research institutes expect GDP growth of 1.3% for the current year and 1.1% and 0.4% for the following two years, respectively. Compared with the spring forecast, the outlook for 2026 has been revised upward by 0.7 and that for 2027 by 0.2 percentage points. “The economy has developed more robustly than expected. However, the recovery rests on a narrow foundation, as high energy prices and structural problems continue to weigh on economic activity,” says Oliver Holtemöller, Head of Macroeconomic Forecasting at the Halle Institute for Economic Research (IWH). In the current quarter, low water levels are also temporarily dampening economic activity. The government deficit continues to increase, leading to a growing need for fiscal consolidation.

Debt Overhang and Real Firm Outcomes
Arsène Buzima Dunia
IWH Discussion Papers,
No. 14,
2026
Abstract
Does debt overhang distort only investment? This paper analyzes the subsequent effects of debt overhang on firm-level outcomes. Using an event study for German firms from 2004 to 2021, we find that, relative to comparable firms in the same industry and year, highly indebted firms do not merely invest less, which is the classic overhang result. They also hire less, and the two margins together translate into slower sales growth. The composition of the adjustment, however, depends on the firm’s growth regime. Highly indebted firms that keep expanding slow their hiring but raise capital per worker over the long run, substituting capital for labour along a flatter expansion path. Highly indebted firms that contract shed workers with no offsetting change in capital intensity: they scale down rather than restructure. These patterns hold in normal times as well as in crises and are concentrated among small and medium-sized limited-liability firms. Debt overhang is therefore not a pure investment wedge but a persistent drag on firm scale, whose incidence across inputs is determined by whether the firm is growing or shrinking.

Economic Outlook: German economy on a recovery path – Tailwinds from the global economy and fiscal policy
An increase in foreign demand has put the German economy on a recovery path in the first half of the year, despite higher energy prices. In the coming quarters, rising public investment is expected to support economic activity. According to the autumn forecast of the Halle Institute for Economic Research (IWH), gross domestic product (GDP) is projected to grow by 1.4% this year and by 0.8% in 2027. Economic recovery in eastern Germany is expected to be somewhat weaker. In June, the IWH economists had predicted growth of 0.9% for both this and the next year.

Abstract
Socioeconomic inequalities shape who accesses early childcare, even in countries that claim universal provision. This entrenched inequality limits child development, women’s employment and gender equality — but governments have clear tools to close the gap.

Distributional Income Effects of Banking Regulation in Europe
Melina Ludolph, Lena Tonzer, Lars Brausewetter
Journal of Corporate Finance,
Vol. 100 (July),
2026
Abstract
We study the impact of stricter and more harmonized banking regulation along the income distribution using household survey data for 25 EU countries. Exploiting country-level heterogeneity in the implementation of European Banking Union directives allows us to control for confounders and identify effects. Our results show that these regulatory reforms aimed at increasing financial system resilience affect households heterogeneously and result in a widening of the income distribution. These results are dependent on a country’s ex-ante regulatory stringency, and more pronounced in countries with stronger bank dependence. Furthermore, we find that more stringent regulation reduces income growth for low-income households primarily due to exits from employment, whereas affluent households tend to experience increased growth rates for employee and self-employed income.

Economic Outlook: Between Energy Crisis and AI Boom
Until the outbreak of the energy crisis, the German economy was on a path to recovery. Now the recovery will only continue over the course of 2026 if the Gulf conflict eases and energy prices do not rise further. This assumption underlies the present summer forecast of the Halle Institute for Economic Research (IWH). In that case, German output is expected to increase by 0.9% for this year and for 2027. Growth rates in East Germany will be similar. In March, the IWH economists had predicted growth of 0.7% for 2026 and 1% for the next year.

Off the Labor Supply Curve: The Zero Employer Size Wage Effect Within Large Firms
André Diegmann, Steffen Müller, Benjamin Schoefer
IWH Discussion Papers,
No. 8,
2026
Abstract
We revisit the employer size wage effect (ESWE) – arguably the most basic and influential departure from the law of one price for labor. Our main result is that this canonical fact disappears completely across establishments within the same firm, even though they operate in different local labor markets. We uncover and dissect this fact by including a firm fixed effect in otherwise standard cross-sectional regressions of wages on establishment size. We implement this demanding specification in population-wide triple-linked firm-establishment-employee data in Germany. This result is new in the ESWE literature (for which our paper also provides the first systematic meta-analysis). This wage-size decoupling is hard to square with the view that employment is determined along a finitely elastic employerspecific labor supply curve – i.e., employers pay exactly the minimum needed for the quantity of labor, but no more – the foundation of the monopsony view. By contrast, large multi-establishment firms (MEF) appear to hire off their labor supply curves (or those curves are very elastic), pay wage premia above the monopsonistic minimum, and leave excess labor supply. We find some evidence for a reemergence of the ESWE within low-premium MEFs. Overall, at least for the 25% of German employment in large firms for which the ESWE disappears, wage setting and employment determination may be better accounted for by alternative models, namely accommodating above-market-clearing wage premia and rationing of labor supply, such as efficiency wage theories.
