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.

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.”

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.
