The Tipping Point for Agent-Based Modeling with Rob Axtell

In this episode of The Flux, John Cordier interviews Rob Axtell from
George Mason University, where he leads the largest graduate program
in agent-based modeling (ABM) globally. Axtell shares his journey into
complex systems modeling and how the field has evolved since the
1990s. He explains how George Mason’s Ph.D. program in
Computational Social Science is shaping the next generation of experts
who go on to roles in government, research, and the private sector.

They discuss the power of agent-based models to simulate real-world
dynamics, from consumer behavior to macroeconomics, highlighting the
increasing availability of data and computing power that allows ABM to
compete with traditional models used by institutions like central banks.
Axtell emphasizes the need for more empirical grounding in ABM and
the potential to build large-scale, highly detailed models, including the
exciting possibility of simulating entire economies.

Axtell also touches on the importance of modeling social complexity at
the individual level, the challenges of past limitations in data, and the
unique potential of ABM to provide a more accurate picture of systems
like financial markets.

For those new to the field, Axtell offers practical advice on getting
started, emphasizing the value of tools like NetLogo as a gateway to
ABM. Whether you're a student, researcher, or data enthusiast, this
episode provides a deep dive into the cutting-edge applications of ABM
and its future impact.
