East Germany's lead over West Germany in terms of growth is bound to shrink – Implications of the Joint Economic Forecast Spring 2024 for the East German economy
In 2023, the East German economy is expected to have expanded by 0.5%, while it shrank by 0.3% in Germany as a whole. The Halle Institute for Economic Research (IWH) forecasts an East German growth rate of 0.5% again for 2024, and a rate of 1.5% in 2025. The unemployment rate is expected to be 7.3% in 2024 and 7.1% in the following year.

Forecasting Economic Activity Using a Neural Network in Uncertain Times: Monte Carlo Evidence and Application to the
German GDP

Abstract
In this study, we analyzed the forecasting and nowcasting performance of a generalized regression neural network (GRNN). We provide evidence from Monte Carlo simulations for the relative forecast performance of GRNN depending on the data-generating process. We show that GRNN outperforms an autoregressive benchmark model in many practically relevant cases. Then, we applied GRNN to forecast quarterly German GDP growth by extending univariate GRNN to multivariate and mixed-frequency settings. We could distinguish between “normal” times and situations where the time-series behavior is very different from “normal” times such as during the COVID-19 recession and recovery. GRNN was superior in terms of root mean forecast errors compared to an autoregressive model and to more sophisticated approaches such as dynamic factor models if applied appropriately.

Germany stuck in stagnation ‒ private consumption remains below pre-pandemic levels
Weak consumption and investment in Germany are partly due to inflation-induced losses in real income and declines in energy-intensive production. However, concerns about the competitive strength of the German economy are also weighing on the willingness of private households and companies to spend. In its spring forecast, the Halle Institute for Economic Research (IWH) expects gross domestic product to expand by just 0.2% in 2024, while the forecast for 2025 includes growth of 1.5% (eastern Germany: 0.5% and 1.4%). Last December, the IWH forecast had assumed an increase of 0.5% for Germany in 2024 and of 1.2% for 2025.
