Joint Economic Forecast 1/2025: Geopolitical turn intensifies crisis – structural reforms even more urgent
The German economy will continue to tread water in 2025. In their spring report, the leading economic research institutes forecast an increase in gross domestic product of just 0.1% for the current year. For 2026, the institutes expect gross domestic product to increase by 1.3%. In the short term, the new US trade policy and economic policy uncertainty are weighing on the German economy. The additional scope for public debt should gradually have an expansionary effect, but threatens to crowd out private consumption and private investment.

Do Markets Value Manager-investor Interaction Quality? Evidence from IPO Returns
Shibo Bian, Iftekhar Hasan, Xunxiao Wang, Zhipeng Yan
Review of Quantitative Finance and Accounting,
August
2024
Abstract
This paper investigates the impact of manager-investor interaction quality on stock returns by utilizing an online IPO roadshow dataset and leveraging a word-embedding model. We find that such interactions are positively valued, as reflected in initial returns. The effect is particularly pronounced for firms characterized by higher levels of information asymmetry, greater investor attention, increased question uncertainty, or discussions on topics not covered in prospectus. Additionally, our research reveals that effective management communication leads to increased first-day turnover rates and thus higher returns. These heightened returns persist up to 180 days following the IPO, without displaying a significant long-term reversal associated with interaction quality. These findings underscore the meaningful impact of the quality of manager-investor interactions on firm valuation.
