🧪 Economics Market Dynamics Simulation

This simulation demonstrates market dynamics — supply, demand, competition and pricing — through a live continuous double auction: rows of buyer and seller agents with private valuations and costs are matched at random, submit random bids and asks, and trade whenever a bid clears an ask. Watching the market price series converge toward the theoretical competitive equilibrium, even though every agent bids with no strategy at all, is the classic Gode & Sunder zero-intelligence-trader result. A cost-shock control lets you shift the supply side and watch equilibrium price, trade volume and allocative efficiency respond, and a constrained-vs-unconstrained toggle shows why the budget constraint — not intelligence — is what drives efficient pricing.
