  Public policy making has direct and indirect impacts on social behaviors.
However, using system dynamics model alone to assess these impacts fails to
consider the interactions among social elements, thus may produce doubtful
conclusions. In this study, we examine the political science theory of greed
and grievance in modeling civil conflicts. An agent-based model is built based
on an existing rebellion model in Netlogo. The modifications and improvements
in our model are elaborated. Several case studies are used to demonstrate the
use of our model for investigating emergent phenomena and implications of
governmental policies.
