This paper introduces "co-opetition" (combining competition and cooperation) to reinsurance risk-sharing. A two-layer game-theoretic framework models insurer-reinsurer contracting and price competition (Stackelberg-Nash), followed by collaborative risk-sharing. The model, using mean-variance preferences, yields explicit equilibrium results, demonstrating the feasibility of analyzing complex reinsurance market dynamics. Future research could explore different preferences, premium principles, and market structures.

"#processmining has become a standard in many companies as part of #processcontrol in various areas. Previous papers for specific areas have discussed its use to ensure good #governance. This paper proposes generic use cases of process mining in the context of #assurance activities in the three-lines-of-defense model and validates with real corporate data from a multinational company."
"This study proposes a comprehensive method (with representative AI-Technologies as a data basis) for the structured and targeted categorization and classification of AI under the risk-based audit approach. Initial feedback received by AI-Experts regarding the design and development of the artifact is collected. With the developed method, the study contributes to the descriptive and prescriptive knowledge base regarding the categorization and classification of AI within the auditing and accounting profession."
