Es ist jedoch kein positiver Zusammenhang zwischen dem Grad der Qualität des Net Working Capital Managements und der Profitabilität zu erkennen. Unternehmen mit längerem Cash Conversion Cycle sind besser durch die Krise gekommen als Unternehmen mit einem „aggressiveren“ Cash Management.

Praxisnahe Themen wie Kapitalflussrechnung, Selbstkostenberechnung und Eigen- vs. Fremdfertigung werden in Deutsch und Englisch anhand von fünf Kriterien (Korrektheit, Vollständigkeit, Plausibilität, An-wendbarkeit, Verständlichkeit) geprüft und von und ChatGPT ein zweites Mal geprüft. Die Ergeb-nisse zeigen, dass LLMs im ersten Schritt strukturierte und plausible Lösungen liefern, jedoch ihre Leistung in der Selbsteinschätzung stark überbewerten. Signifikanztests bestätigen, dass die Selbst-einschätzungen deutlich positiver ausfallen als die Bewertungen durch eine neutrale Künstliche Intelligenz (KI) und den Vergleich mit Musterlösungen. Entgegen der Erwartung können die LLMs englischsprachige Aufgaben nicht besser lösen als deutschsprachige. Auch dieser Zusammenhang erweist sich als statistisch signifikant. Die Ergebnisse verdeutlichen, dass menschliche Expertise und Kontrolle für strategische Entscheidungen weiterhin unerlässlich sind, während LLMs derzeit vor allem als Unterstützungstools geeignet sind.

Building onFuest et al.(2024), this study examines the financial performance of publicly listed high-and mid-techcompanies from a shareholder'sperspective. Using data from theEU Industrial R&D Investment Scoreboard and LSEGWorkspace for 2,349 listed companies, market-capitalization-weighted portfolios were constructed and benchmarked against global and local market indices. Performance was evaluated using theSharpe ratio and multi-factor asset pricing models (Carhart four-factor and Fama-French five-factor), distinguishing between crisis and non-crisis periods, as well as regional and sectoral variations. Results showthat, at the aggregate level,high-tech portfolios consistentlyand significantly outperform mid-tech and "other" categories on absolute and risk-adjusted bases. Mid-tech indus-tries exhibitresilience during crisis but lower alphasthan high-techindustries,and sectoral heterogeneity high-lightsdiversification benefits. Furthermore, theanalysis reveals investment opportunities in R&D-intensive sec-tors, emphasizing crisis resilience and regional competitiveness.

Certification of cloud services is the most promising method in overcoming the current issues. However, this paper examines that existing certificates for cloud service providers don’t match the requirements of public administrations. The analyzed cloud certificates focus strongly on the information security management. But they only have a general look on data protection management. The missing focus on the special requirements of public administrations with regards to geo location of servers, the US cloud act, and especially prevention of foreign state access of PII data (personally identifiable information) is most critical for the use in public administrations. This article shows that a FedRAMP equivalent certification process combined with a European cloud certificate especially designed for the public administration could be the trigger to a successful and faster cloud implementation in the public administration sector in Europe that is currently underdeveloped. Furthermore, the large market with millions of buying public administrations in 27 European Union countries would create attractive business opportunities for private cloud providers, foster the development of new applications and serve the strategic goal of data sovereignty.

This paper aims to analyze the financial impact of women in executive positions in German companies by examining the economic value added and exploring the effects of Environmental, Social, and Governance (ESG) factors and female supervisory board members on female board members. The results indicate that in the 200 largest German companies, the share of female executives increased between 2018 and 2022. Regardless of industry, female executives started at very low levels at around 4% in 2018; in 2022, this figure reached around 11%. Thereby, the financial sector showed the highest share of female executives at around 14% in 2022, and the industrial sector at around 9%. A closer look reveals that large companies have higher shares of female executives than smaller companies. Large companies show an average of 17% compared to small ones, and in 2022, only 8%. There is a positive correlation between the share of female supervisory board members and female executives, arguing that female supervisory board members seem to hire more female executives. Companies with more female executives tend to have lower ESG controversy scores, and companies with more female executives, measured by the economic value added, perform better financially than companies with few or no women. Companies with female executives show about 2 percentage points higher economic value added than those with the lowest share of females (no or few female executives). Thus, it seems that female executives matter and make a difference in companies.

Die Ergebnisse zeigen für kein Portfolio eine signifikante Über- oder Unterperformance. Lediglich die besten ESG-Firmen tendieren in normalen Marktphasen zu einer Unterperformance. Investoren erleiden beim Berücksichtigen von ESG-Scores auf den DAX risikoadjustiert keinen Nachteil und können zugleich ihrem guten Gewissen Genüge tun.
