Economic growth in East Germany slightly higher than in the West – Implications of the Joint Economic Forecast Spring 2026 and of new data for the East German economy
In 2025, the East German economy expanded by 0.4%, somewhat more than Germany as a whole (0.2%). For 2026, the Halle Institute for Economic Research (IWH) expects growth of 0.7% for East Germany (Germany: 0.6%). The unemployment rate is likely to amount to 7.9% in the current year, after 7.8% in 2025.

Energy price shock dampens recovery – inflation rises
Although the leading economic research institutes consider the German economy to be in a recovery phase following a downturn lasting several years, they nevertheless expect only a moderate increase in gross domestic product of 0.6% for 2026 and 0.9% for 2027. “The energy price shock triggered by the Iran war is hitting the recovery hard, but at the same time expansionary fiscal policy is bolstering the domestic economy and preventing a stronger slide,” says Timo Wollmershäuser, Head of Forecasts at the ifo Institute. The institutes estimate that the inflation rate will rise to an average of 2.8% in 2026 and 2.9% in 2027.

Energiepreisschock überlagert Fiskalimpuls – Wachstumskräfte versiegen
Dienstleistungsauftrag des Bundesministeriums für Wirtschaft und Energie,
No. 1,
2026
Abstract
Nach einem mehrjährigen Abschwung hat im Verlauf des vergangenen Jahres eine Erholung eingesetzt. Während die exportorientierte Industrie angesichts weiter abnehmender Wettbewerbsfähigkeit, hoher geopolitischer Unsicherheit und fortbestehender handelspolitischer Belastungen kaum Tritt fasste, wurde die Erholung maßgeblich von der Binnenwirtschaft getragen. Der Energiepreisschock, der durch den Iran-Krieg ausgelöst wurde, dämpft die Erholung, dürfte sie aber nicht vollständig zum Erliegen bringen. Dafür sorgt der erheblich expansive Kurs der Finanzpolitik, der vor allem Unternehmen der Verteidigungsindustrie und des Tiefbaus stützt. Im Großteil des Verarbeitenden Gewerbes bleibt die Lage jedoch verhalten.
Das Bruttoinlandsprodukt dürfte in diesem Jahr um 0,6% und im Jahr 2027 um 0,9% zunehmen, nachdem die Wirtschaftsleistung im Vorjahr mit einem Anstieg von 0,2% kaum mehr als stagniert hat. Im Vergleich zum Herbstgutachten 2025 haben die Institute damit ihre Prognose für das laufende Jahr deutlich um 0,6 Prozentpunkte und für das kommende Jahr um 0,4 Prozentpunkte nach unten korrigiert.

Oil price shock threatens recovery in Germany
Globally rising energy prices in the wake of the new Gulf War are clouding the outlook for the German economy. Nevertheless, increased public expenditure is expected to support economic activity both this year and next. According to the spring forecast of the Halle Institute for Economic Research (IWH), output is projected to grow by 0.7% in 2026 and by 1.0% in 2027. We expect similar rates of expansion for East Germany. In December, the IWH economists had predicted growth of 1.0% for both 2026 and 2027.

Konjunktur aktuell: Ölpreisschock gefährdet Erholung in Deutschland
Konjunktur aktuell,
No. 1,
2026
Abstract
Weltweit höhere Energiepreise infolge des neuen Golfkriegs verschlechtern die Aussichten für die deutsche Konjunktur, auch wenn Mehrausgaben der öffentlichen Hand die gesamtwirtschaftliche Expansion in diesem und im kommenden Jahr stützen werden. Die Produktion dürfte im Jahr 2026 um 0,7% und im Jahr darauf um 1% zunehmen. Ähnliche Expansionsraten sind auch für Ostdeutschland zu erwarten.

Fiscal Expansion and Households’ Income Inequality Expectations: A Survey Experiment
Melina Ludolph, Giang Nghiem, Lena Tonzer
Abstract
We study how individuals’ views on current and future levels of income inequality change during periods of expansionary fiscal policy. In a randomized controlled trial (RCT), we provide information on fiscal expansion to a representative sample of the German population. Our findings reveal that combining a fact-based (numerical) information treatment with a narrative treatment about fiscal expansion plans reduces inequality expectations among respondents who are ex-ante dissatisfied with the government’s economic policy. These effects are more pronounced among respondents without a college degree or with low political interest, highlighting the importance of narrative information for individuals who are likely to benefit most from it. We explore potential mechanisms by examining revisions in macro- and micro-level assessments of future economic conditions and find that respondents primarily update their expectations regarding economic growth and individual layoff risk.

IWH-Flash-Indikator I. und II. Quartal 2026
Katja Heinisch, Oliver Holtemöller, Axel Lindner, Birgit Schultz
IWH Flash Indicator,
No. 1,
2026
Abstract
Die deutsche Wirtschaft legte im vierten Quartal 2025 um 0,3% zu, nachdem sie in den beiden Quartalen zuvor noch geschrumpft war. Vor allem zum Ende des Jahres 2025 stiegen die privaten und staatlichen Konsumausgaben. Das Bruttoinlandsprodukt (BIP) hat damit im Jahr 2025 insgesamt um 0,2% zugenommen. Dabei dürften vor allem die Konsumausgaben die fehlenden Wachstumsimpulse des Außenhandels kompensiert haben. Die jüngsten Indikatoren deuten auf eine leichte konjunkturelle Belebung hin (vgl. Abbildung 1). Laut IWH-Flash-Indikator dürfte das Bruttoinlandsprodukt (BIP) im ersten Quartal 2026 um 0,3% und im zweiten Quartal 2026 um 0,2% steigen.

Going Public and the Internal Organization of the Firm
Daniel Bias, Benjamin Lochner, Stefan Obernberger, Merih Sevilir
Journal of Finance,
Vol. 81 (1),
2026
Abstract
This paper examines how initial public offerings (IPOs) affect firms' internal organization. We find that IPO firms become more hierarchical and standardized organizations, characterized by additional layers, more managers, smaller control spans, and larger administrative functions. These changes occur mostly in preparation for the IPO and can be only partially explained by growth. IPO firms with greater human capital risk experience larger hierarchical changes. Hierarchical changes help firms standardize employee roles and formalize internal processes. Our results suggest that firms reorganize to reduce their dependence on key individuals' human capital when transitioning to public markets.

Smooth and Persistent Forecasts of German GDP: Balancing Accuracy and Stability
Katja Heinisch, Simon van Norden, Marc Wildi
IWH Discussion Papers,
No. 1,
2026
Abstract
Forecasts that minimize mean squared forecast error (MSE) often exhibit excessive volatility, limiting their practical applicability. We address this accuracy-smoothness trade-off by introducing a Multivariate Smooth Sign Accuracy (M-SSA) framework, which extracts smoothed components from leading indicators to enhance the signal-to-noise ratio and control the forecast volatility and timing. Applied to quarterly German GDP growth, our method yields smoothed forecasts that can improve forecasting accuracy, particularly over medium-term horizons. We find that while smoother forecasts tend to lag slightly around turning points, this can be offset by adjusting the forecast horizon. These findings highlight the practicality of the M-SSA framework for both forecasters and policymakers, especially in settings where forecast revisions or policy adjustments are costly.

Compliance with the EU fiscal rules requires extensive consolidation – Medium-term projection of macroeconomic developments and public finances in Germany
Germany faces considerable structural burdens from both macroeconomic and fiscal perspectives, as potential growth is likely to be significantly lower than in past decades. A projection by the Halle Institute for Economic Research (IWH) on macroeconomic developments up to the year 2040 shows that, under unchanged fiscal policies, public debt can be expected to continue rising. The federal government's fiscal-structural plan assumes compliance with EU requirements, but this is only achievable under the assumption of high global spending cuts that have not yet been specified in detail.
