Technical Report
Full-text available
This study developed a novel hybrid agent-based and system dynamics (AB-SD) model for an ecological economic system. The complex nature of an ecological economic system prevents us from seeing the system and its behavior as it is, which calls for a model. A model simplifies reality and reveals certain aspects of it. The modeling approach chosen, ho...

We provide a system dynamics implementation of a dynamic ecological economics model. Dynamic economic models are often constrained to use functions, such as the Cobb-Douglas function, chosen "conveniently" to allow for analytic solutions. The C-D function, however, suffers from its fixed elasticity that does not allow for the substitutability betwe...
