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

EREI-Update: Rents in Europe’s cities are 23% higher on average than in rural areas
The European Commission currently prepares the Affordable Housing Act to tackle widespread concerns about tight housing markets, for example voiced by the German Tenants' Federation (DMB) which blames rising rental cost as one main driver of a social crisis in Germany. The latest European Real Estate Index (EREI) by the Halle Institute for Economic Research (IWH) shows that rental prices in Germany rose indeed three times compared to the European average in August. Moreover, the rental premium in metropolitan areas vis-à-vis the average in non-metropolitan areas in eleven EU member states amounts to 23%.

Launch of the European Real Estate Index (EREI): German housing prices continue to rise more slowly than in Europe
Growth in asking prices for German residential properties offered for sale has lagged the European EREI aggregate since spring 2025. This is shown by the new European Real Estate Index (EREI) presented today by the Halle Institute for Economic Research (IWH). This novel data service hinges on more than 43 million listings on online real estate platforms and provides monthly comparisons of residential asking prices and advertised rents across 1,154 European regions in near-real-time.

Abstract
Real estate is a capstone connection between various economic agents and markets. It is the main store of household wealth, serves as collateral for mortgage loans in the banking system, aids the transmission of monetary policy, and can propagate financial crises when overvalued. Yet comparable house-price data across the European Union (EU) and the euro area is unavailable, which hinders the design and evaluation of common monetary and economic policy that operates across heterogeneous housing markets. We derive monthly subnational European Real Estate Indicators (EREI) from online residential property advertisements in 16 European countries. The release covers April 2024 to June 2026 and contains 48,168 region-month-segment observations for 1,154 NUTS 3 regions, aggregating more than 43 million listing observations across the monthly sale and rental cross-sections. Each region-month segment reports the number of advertisements and summary statistics for asking prices per square meter and listing durations. The release also includes sale-segment indices for Europe, the euro area, and individual countries. Thirteen covered countries are EU members, which represented 85% of EU-27 gross domestic product in 2024. EREI data support research on a wide range of socio-economic phenomena associated with real estate dynamics, such as the evaluation of monetary policy or macroprudential policy effects on financial stability.

Distributional Income Effects of Banking Regulation in Europe

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.

Reassessing EU Comparative Advantage: The Role of Technology

International Economics,
Vol. 183,
2025
Abstract
Based on a sufficient statistics approach, we show how the state of technology of European industries relative to the rest of the world can be empirically assessed in a way that is simple in terms of computation, parsimonious in terms of data requirements, but still comprehensive in terms of information. The lack of systematic cross-industry correlation between export specialization and technological advantage suggests that standard measures of revealed comparative advantage only imperfectly capture a country’s technological prowess due to the concurrent influences of factor prices, market size, markups, firm selection and market share reallocation. These findings offer policy insights relevant to the EU’s external competitiveness debate, echoing several recommendations from the Draghi report. Achieving export specialization in key sectors requires more than just technological superiority.

Road to Net Zero: Carbon Policy and Redistributional Dynamics in the Green Transition
Alessandro Sardone
IWH Discussion Papers,
No. 16,
2025
Abstract
This paper examines the macroeconomic and distributional effects of the European Union’s transition to Net Zero emissions through a gradually increasing carbon tax. I develop a New Keynesian Environmental DSGE model with two household types and distinct energy and non-energy sectors. Five alternative uses of carbon tax revenues are considered: equal transfers to households, targeted transfers to Hand-to-Mouth households, subsidies to green energy firms, and reductions in labor and capital income taxes. In the absence of technological progress, the carbon tax policy induces a persistent increase in energy prices and a reduction in GDP, investment, and consumption. Headline inflation falls below zero in the medium run, reflecting weaker aggregate demand. Distributional outcomes vary significantly depending on the implemented revenue recycling scheme: targeted transfers are the most progressive but entail larger macroeconomic costs, while subsidies and tax cuts mitigate output and investment losses but are less effective in narrowing the consumption gap. A limited foresight scenario, in which agents learn about policy targets sequentially, generates more volatile adjustment paths and temporary inflationary spikes around announcements, but long-run outcomes remain close to the baseline.
