This project aims to develop a quantified and scalable decision model for sustainable corporate financing. Findings from various sub-disciplines of finance and financing practice are to be integrated into an overall model. At the same time, a validation with capital market data is to be implemented so that the model can adapt dynamically over time. The model is to be incorporated into the DebtPilot software, which is licensed by banks and used in the customer advisory process. The aim is to use various simulated scenarios to optimize the advice given to borrowers on their long-term financing strategy. In addition, a macroeconomic benefit should arise from the fact that statements about the sustainability of the entire credit market can be obtained (and published) based on the model and benchmarking.
