Playable market-clearing challenge
Nudge a street market toward equilibrium without directly commanding every buyer or seller. Set price expectations, release supply, and watch decentralized choices create shortages, surpluses, welfare gains, or deadweight loss.
Your levers
You do not control individual agents. Your posted price and producer guidance change the incentives each side sees, then the invisible hand emerges from their responses.
Live market
Tune the controls, then open the market day to see whether price coordinates buyers and sellers.

Prices compress information. A high price invites production and screens out low-value buyers; a low price expands demand but can create scarcity if producers cannot cover costs.
