ORIGINAL EXPERIMENT / MATHEMATICAL MODEL
Money behaves like a gas.
Two thousand agents start equal. They exchange at random; the dashed curve is the model’s predicted equilibrium.
Nobody is smarter. Nobody cheats. The total never changes. A distribution emerges anyway. Compare .
Kinetic exchange model: Drăgulescu & Yakovenko (2000). A simplified mathematical system, not a complete explanation of wealth or a policy claim. The original deterministic experiment is preserved here.
