Description:
cadCAD is a differential games based simulation software package for research, validation, and Computer
Aided Design of economic systems. An economic system is treated as a state based model and defined through a
set of endogenous and exogenous state variables which are updated through mechanisms and environmental
processes, respectively. Behavioral models, which may be deterministic or stochastic, provide the evolution of
the system within the action space of the mechanisms. Mathematical formulations of these economic games
treat agent utility as derived from state rather than direct from action, creating a rich dynamic modeling framework.
Simulations may be run with a range of initial conditions and parameters for states, behaviors, mechanisms,
and environmental processes to understand and visualize network behavior under various conditions. Support for
A/B testing policies, monte carlo analysis and other common numerical methods is provided.
