1. Agent-based model of a simple stable economy Alexandre Lomovtsev Adviser: Dr. Russ Abbott

2. Basic economic models supply-driven: most economic entities are dependent on the supplies available to be consumed directly or to be used to produce something for consumption. demand-driven: economic entities are dependent on the demand (for their services). Abstract

3. Objectives Develop a framework for building simple economy models. Attempt to find the tipping point between supply-driven and demand-driven economy models.

4. Modeling Environment NetLogo 4.0  multi-agent system  simple environment  sufficient visualization  easy learning curve

5. NetLogo 4.0 Main entities - agents –patches (stationary agents) –turtles (dynamic agents) –links (stationary connecting two turtles) –observer – environment control Instructions –procedures (implemented by the user) –primitives (built into NetLogo) Variables –global –own by agent (built-in and user-defined) –local
