Abstract
This study provides new evidence on the impact of the EU Cohesion Policy on income growth in less developed regions. Our panel includes data from all European regions for the years 1989-2020. Using a fuzzy Regression Discontinuity Design, we model treatment dynamics by applying a random effects estimator. Based on digitized historical data, we precisely replicate the policy rule and correctly classify the regions’ eligibility status. Results show that the policy has a moderate positive effect on GDP per capita growth in the targeted regions.

Joint Economic Forecast Autumn 2025: Fiscal stimulus masks structural weakness
The German economy is emerging from the trough and is likely to regain some momentum over the next two years. Following stagnation in the first half of the year, the Joint Economic Forecast project group predicts gross domestic product growth of 0.2% for the current year in its fall report. In the next two years, an expansionary fiscal policy is likely to accelerate economic growth noticeably to 1.3% and 1.4%, respectively. This means that the institutes' forecast for this year and next remains roughly unchanged from the spring report. “The German economy is still on shaky ground,” says Dr Geraldine Dany-Knedlik, head of the Forecasting and Economic Policy Division at the German Institute for Economic Research (DIW Berlin). “It will recover noticeably in the next two years. However, given ongoing structural weaknesses, this momentum will not last.”

Declining Free Lunch: State Capacity and Foregone Public Spending
Sarah Fritz, Lorenzo Incoronato, Catherine van der List
RFBerlin Discussion Paper,
No. 67,
2025
Abstract
This paper documents substantial fiscal waste in the context of one the world’s largest regional development programs – the EU Cohesion Policy. We study Italy, and find that 20% of funding commitments are never paid out and funneled into unfinished or never-started projects. In our setting, this happens for reasons unrelated to fiscal constraints – municipalities appear to simply leave money on the table. Foregone spending is more prevalent in Southern regions, but there is also stark variation across municipalities within regions. We show that such under-utilization of available funds is strongly associated with limited administrative capacity of local governments.

Economic recovery in Germany – but structural problems and US trade policy weigh on the economy
The German economy has picked up somewhat in the first half of 2025. This was helped by the temporary increase in demand from the US in anticipation of higher tariffs. If the US does not escalate its trade conflicts further, production in Germany according to the summer forecast of the Halle Institute for Economic Research (IWH) is likely to increase a bit (by 0.4%) in 2025, after two years of decline. In March, the IWH economists were forecasting growth of 0.1% for the current year. Growth of 1.1% is forecast for the year 2026. Similar expansion rates are to be expected for East Germany.

Step by Step ‒ A Quarterly Evaluation of EU Commission's GDP Forecasts
Katja Heinisch
Journal of Forecasting,
No. 3,
2025
Abstract
The European Commission’s growth forecasts play a crucial role in shaping policies and provide a benchmark for many (national) forecasters. The annual forecasts are built on quarterly estimates, which do not receive much attention and are hardly known. Therefore, this paper provides a comprehensive analysis of multi-period ahead quarterly GDP growth forecasts for the European Union (EU), euro area, and several EU member states with respect to first-release and current-release data. Forecast revisions and forecast errors are analyzed, and the results show that the forecasts are not systematically biased. However, GDP forecasts for several member states tend to be overestimated at short-time horizons. Furthermore, the final forecast revision in the current quarter is generally downward biased for almost all countries. Overall, the differences in mean forecast errors are minor when using real-time data or pseudo-real-time data and these differences do not significantly impact the overall assessment of the forecasts’ quality. Additionally, the forecast performance varies across countries, with smaller countries and Central and Eastern European countries (CEECs) experiencing larger forecast errors. The paper provides evidence that there is still potential for improvement in forecasting techniques both for nowcasts but also forecasts up to eight quarters ahead. In the latter case, the performance of the mean forecast tends to be superior for many countries.

Contractionary Macroprudential Policy, Collateral Valuation, and Risk-shifting in EU Banking
Michael Koetter, Felix Noth, Fabian Wöbbeking
IWH Discussion Papers,
No. 4,
2025
Abstract
We study real estate lending responses to tighter macroprudential policy (MPP) in the form of lower required loan-to-value (LTV) ratios. Contract details of 2.4 million mortgage loans originated between 2008 and 2020 reveal significantly fewer new loan issuances in response to contractionary MPP, commensurate with an average reduction in aggregate lending of 21 percent. Loan-level analyses reveal, however, that banks comply with lower LTVs by systematically more benevolent valuations of residential real estate pledged as collateral instead of reducing loan size. Exploiting earthquakes as plausible exogenous shocks to property values corroborates these risk-shifting patterns by banks in the form of inflated property valuations after LTV shocks.
