Frosty prospects for the German economy
The German economy will continue to stagnate in winter 2024/2025. Industry is suffering from a loss of international competitiveness. For this reason and due to the unclear economic policy outlook, firms and consumers are holding back on spending, although incomes have increased recently. Consumer spending will only increase more strongly once the uncertainty subsides. According to the winter forecast of the Halle Institute for Economic Research (IWH), gross domestic product in Germany is expected to fall by 0.2% in 2024 and to expand by 0.4% in 2025. In September, the IWH forecast had still assumed a zero growth in 2024 and a growth of 1.0% in 2025. In East Germany, gross domestic product will increase by 0.5% both this year and in 2025.

Konjunktur aktuell: Frostige Aussichten für die deutsche Wirtschaft
Konjunktur aktuell,
No. 4,
2024
Abstract
Zur Jahreswende dürfte die weltweite Produktion weiterhin in etwa so schnell wie in der Dekade vor der Pandemie expandieren. Die Konjunktur im Euroraum ist nur verhalten, und die Stagnation der deutschen Wirtschaft setzt sich fort. Die Industrie verliert an internationaler Wettbewerbsfähigkeit. Unternehmen und Verbraucher halten sich aufgrund unklarer wirtschaftspolitischer Aussichten mit ihren Ausgaben zurück. Das Bruttoinlandsprodukt dürfte im Jahr 2024 um 0,2% sinken und im Jahr 2025 um 0,4% expandieren.

IWH-Flash-Indikator IV. Quartal 2024 und I. Quartal 2025
Katja Heinisch, Oliver Holtemöller, Axel Lindner, Birgit Schultz
IWH-Flash-Indikator,
No. 4,
2024
Abstract
Der deutsche Konjunkturmotor stottert weiter vor sich hin. Obwohl das Bruttoinlandsprodukt (BIP) im dritten Quartal 2024 um 0,2% zunahm, liegt es immer noch unter dem Niveau vom ersten Quartal 2024, da das zweite Quartal nach neuesten Zahlen weitaus schwächer ausgefallen ist als zuvor gemeldet (vgl. Abbildung 1). Der leichte Zuwachs im dritten Quartal dürfte dabei vor allem auf gestiegene staatliche und private Konsumausgaben zurückzuführen sein. In den Unternehmen ist die Stimmung weiterhin trüb und die wirtschaftspolitische Unsicherheit dürfte weiterhin hoch bleiben. Zudem belasten nach wie vor gestiegene Energie- und Lohnkosten die Investitionsbereitschaft der Unternehmen. Alles in allem dürfte das Bruttoinlandsprodukt (BIP) laut IWH-Flash-Indikator im vierten Quartal 2024 stagnieren. Für den Jahresbeginn 2025 deuten allerdings die Frühindikatoren auf eine Belebung der wirtschaftlichen Aktivitäten und einen Anstieg des BIP um 0,4% hin. Diese reflektieren jedoch noch nicht die jüngsten politischen Ereignisse in den USA und in Deutschland.

Step by Step ‒ A Quarterly Evaluation of EU Commission's GDP Forecasts
Katja Heinisch
IWH Discussion Papers,
No. 22,
2024
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.

Forecast Combination and Interpretability Using Random Subspace
Boris Kozyrev
IWH Discussion Papers,
No. 21,
2024
Abstract
This paper investigates forecast aggregation via the random subspace regressions method (RSM) and explores the potential link between RSM and the Shapley value decomposition (SVD) using the US GDP growth rates. This technique combination enables handling high-dimensional data and reveals the relative importance of each individual forecast. First, it is possible to enhance forecasting performance in certain practical instances by randomly selecting smaller subsets of individual forecasts and obtaining a new set of predictions based on a regression-based weighting scheme. The optimal value of selected individual forecasts is also empirically studied. Then, a connection between RSM and SVD is proposed, enabling the examination of each individual forecast’s contribution to the final prediction, even when there is a large number of forecasts. This approach is model-agnostic (can be applied to any set of predictions) and facilitates understanding of how the aggregated prediction is obtained based on individual forecasts, which is crucial for decision-makers.

Services stabilise the East German economy – Implications of the Joint Economic Forecast Autumn 2024 and of Länder data from recent publications of the Statistical Offices
In 2024, the East German economy is expected to grow by 0.2%, while it will decline by 0.1% in Germany as a whole. The Halle Institute for Economic Research (IWH) is forecasting an East German growth rate of 0.7% in 2025, and a rate of 1.2% in 2026. According to the IWH forecast, the unemployment rate in eastern Germany is likely to be 7.5% in 2024 as well as 2025 and 7.2% in 2026.

Joint Economic Forecast 2/2024: German economy in transition ‒ weak momentum, low potential growth
The Joint Economic Forecast Project Group forecasts a 0.1% decline in Germany's gross domestic product in 2024. Looking further ahead, the institutes expect a weak recovery with growth of 0.8% (2025) and 1.3% (2026). Compared to the spring forecast, this represents a down-ward revision of 0.2 (2024) and 0.6 (2025) percentage points. “In addition to the economic downturn, the German economy is also being weighed down by structural change,” says Dr Geraldine Dany-Knedlik, head of Forecasting and Economic Policy at the German Institute for Economic Research (DIW Berlin). “Decarbonisation, digitalisation, and demographic change – alongside stronger competition with companies from China – have triggered structural adjustment processes that are dampening the long-term growth prospects of the German economy.”

Deutsche Wirtschaft im Umbruch – Konjunktur und Wachstum schwach
Dienstleistungsauftrag des Bundesministeriums für Wirtschaft und Klimaschutz,
No. 2,
2024
Abstract
Die deutsche Wirtschaft tritt seit über zwei Jahren auf der Stelle. In den kommenden Quartalen dürfte eine langsame Erholung einsetzen. Aber an den Trend von vor der COVID-19-Pandemie wird das Wirtschaftswachstum auf absehbare Zeit nicht mehr anknüpfen können. Die Dekarbonisierung, die Digitalisierung, der demografische Wandel und wohl auch der stärkere Wettbewerb mit Unternehmen aus China haben strukturelle Anpassungsprozesse in Deutschland ausgelöst, die die Wachstumsaussichten für die deutsche Wirtschaft dämpfen.
Das Bruttoinlandsprodukt dürfte im Jahr 2024 um 0,1% sinken und in den kommenden beiden Jahren um 0,8% bzw. 1,3% zunehmen. Damit revidieren die Institute ihre Prognose vom Frühjahr 2024 leicht nach unten. Getragen wird die schmalspurige Erholung vom steigenden privaten Verbrauch, der von kräftigen Zuwächsen der real verfügbaren Einkommen angeregt wird. Das Anziehen der Konjunktur in wichtigen Absatzmärkten, wie den europäischen Nachbarländern, wird den deutschen Außenhandel stützen. Zusammen mit günstigeren Finanzierungsbedingungen kommt dies den Anlageinvestitionen zugute. Die Wirtschaftspolitik sollte Produktivitätshemmnisse abbauen, den Strukturwandel zulassen und die politische Unsicherheit verringern.

Moderate economic growth in the world – German economy continues to stagnate
Production in Germany has been stagnating for two years and is roughly the same level as shortly before the outbreak of the pandemic. Investment of firms is particularly weak. An important reason for fewer investments is the sluggish export business. Private households are also holding back on consumption, mainly due to concerns about the longer-term economic outlook. According to the autumn forecast of the Halle Institute for Economic Research (IWH), gross domestic product in Germany is likely to stagnate in 2024 and to increase by 1.0% in 2025 as capacity utilisation normalises. In June, the IWH forecast had still assumed a growth of 0.3% in 2024 and of 1.5% in 2025. In East Germany, gross domestic product will increase by 0.3% this year and by 0.9% in 2025.

Moderate economic growth in the world – German economy continues to stagnate
Konjunktur aktuell,
No. 3,
2024
Abstract
The recent moderate pace of the global economy will continue for the time being. In Europe, the economy is likely to pick up slightly from the winter half-year 2024/2025. In Germany, the sluggish export business in particular is providing a lack of economic impetus. However, private consumption will contribute to a slight economic recovery in the winter half-year. Gross domestic product is likely to stagnate in 2024 and grow by 1.0% in 2025.
