# Agent-Based Computational Finance¶

In cooperation with Blake LeBaron and the Institute for New Economic Thinking,
*Patrick Herb* and *Axel Szmulewiez* are in the process of developing a suite of
agent-based software to assist in both teaching and research efforts. We are
considering some of the classic agent-based finance papers and writing
computer programs that replicate either some or all of their key results.
Most programs will be written in Matlab or NetLogo, but some may be composed
in Python. Interested entities may download these programs free of charge.
