Abstract
This study explores the evolution of accounting research by utilizing an unsupervised machine learning approach. We aim to identify the latent topics of accounting from the 1980s up to 2018, the dynamics and emerging topics of accounting research, and the economic reasons behind those changes. First, based on 23,220 articles from 46 accounting journals, we identify 55 topics using the latent Dirichlet allocation model. To illustrate the connection between topics, we use HistCite to generate a citation map along a timeline. The citation clusters demonstrate the “tribalism” phenomenon in accounting research. We then implement the dynamic topic model to reveal the dynamics of topics to show changes in accounting research. The emerging research trends are identified from the topic analytics. We further explore the economic reasons and in-depth insights into the topic evolution, indicating the economic development embeddedness nature of accounting research.

The downturn in 2023 is milder in East Germany than in Germany as a whole – Implications of the Joint Economic Forecast Autumn 2023 and of Länder data from recent publications of the Statistical Offices
The German economy has been in a downturn for more than a year. In East Germany, however, the economy has been somewhat stronger in the past four quarters: According to the Halle Institute for Economic Research (IWH), East German gross domestic product (GDP) is expected to increase by 0.5% in 2023, while production in Germany as a whole will fall by 0.6%. Next year, expansion rates of 1.3% are forecast in both the east and the west. For 2025, East German gross domestic product is expected to grow by 1.2%, which is slightly slower than in Germany as a whole (1.5%).

Joint Economic Forecast 2/2023: Purchasing power returns ‒ political uncertainty high
According to the Joint Economic Forecast, Germany's gross domestic product declines by 0.6% in 2023. This is a strong downward revision of 0.9 percentage points from the forecast made in spring 2023. "The most important reason for this revision is that industry and private consumption are recovering more slowly than we expected in spring," says Oliver Holtemöller, Vice President and Head of the Macroeconomics Department at the Halle Institute for Economic Research (IWH).
