2、 is a computational methodology that allows the analyst to create, analyze, and experiment with, artificial worlds populated by agents that interact in non-trivial ways different from other types of computational techniques: econometrics, numerical solutions, macro simulation, Al modelingFour types

5、 primarily local interaction among many, typically heterogeneous agents mutually constituting their own environment. Emergent properties Large numbers of diverse agents Local interaction Adaptation through selection Endogenous, non-parametric environmentWhy use agent-based modeling? ABM helps fill the gap between formal but restrictive models and wide-ranging but imprecise qualitative framewor
