Analysis of earnings calls: Blathering managers harm their company
If a senior executive refuses to give information to professional investors, the company's stock market value drops afterwards. This is shown in a study by the Halle Institute for Economic Research (IWH) after evaluating
1.2 million answers from tele-phone conferences.

Capital Requirements, Market Structure, and Heterogeneous Banks
Carola Müller
IWH Discussion Papers,
No. 15,
2022
Abstract
Bank regulators interfere with the efficient allocation of resources for the sake of financial stability. Based on this trade-off, I compare how different capital requirements affect default probabilities and the allocation of market shares across heterogeneous banks. In the model, banks‘ productivity determines their optimal strategy in oligopolistic markets. Higher productivity gives banks higher profit margins that lower their default risk. Hence, capital requirements indirectly aiming at high-productivity banks are less effective. They also bear a distortionary cost: Because incumbents increase interest rates, new entrants with low productivity are attracted and thus average productivity in the banking market decreases.

Economy in East Germany will not suffer more from the war in Ukraine than in Germany as a whole – Implications of the Joint Economic Forecast Spring 2022 and new data for the East German economy
The recovery of the East German economy, like that of Germany as a whole, will weaken considerably due to Russia’s war in Ukraine. However, the economic slump and recovery were not as pronounced as in West Germany. In 2021, East German output grew by 2.3%, less than in Germany as a whole (2.9%). According to the Halle Institute for Economic Research (IWH), GDP growth in East Germany is also likely to be lower than in Germany as a whole in 2022 (2.1% in East Germany vs. 2.7% in Germany) and 2023 (2.5% vs. 3.1%).

Price shock jeopardises recovery of German economy
Russia’s war in Ukraine is hitting the German economy primarily via an energy price shock, but also by disrupting trade flows and causing general uncertainty. At the same time, however, the economy is receiving a strong boost from the lifting of many pandemic restrictions. The Halle Institute for Economic Research (IWH) forecasts that gross domestic product will increase by 3.1% in 2022. The consumer price index will be 4.8% higher than one year ago. The war affects the East German eco-nomy about as hard as the economy in Germany as a whole.
