Systemic Financial Feedbacks - Conceptual Framework and Modeling Implications

摘要

Different approaches to model feedbacks in financial systems are assessed based on requirements for the conceptualization of the feedback dynamics. Given the non-linear, behavior driven, and interconnected characteristics of systemic financial feedbacks (SFFs), modeling concepts from System Dynamics (SD) theory provide appropriate and attractive features. Surprisingly, few SD models exist to explain systemic financial feedbacks. The scarcity of SD modeling for SFFs may be attributed to the lack of required economically-sound foundations for theoretical modeling. This paper considers a conceptual framework for SFFs that emerges from the synthesis of formal principles of economics and SD. In doing so, this study links existing SFF models to concepts of SD and provides suggestions for further modeling.
