Agent-based Simulation Model of Business Cycle

In order to obtain policy implications on systemic financial fragility, we constructed a macroeconomic model in cooperating heterogeneous economic agents and a financial sector. Since business cycle is a phenomenon emerging from complex interactions among heterogeneous agents, conventional macroeconomic model that assumes a representative agent is inappropriate. We reproduced business cycle behavior using an agent-based approach. A completely closed macro financial model, which in cooperates Keynesian and Walrasian regimes with endogenous money supply, was constructed. This prototype model is expected to be a useful base model to examine various policy simulations.
