🔨 Auction Dynamics (2D)
2D auction-theory lab: run English, Dutch, first-price sealed-bid and Vickrey auctions against bidders with private valuations, and watch revenue, efficiency and surplus converge toward the Revenue Equivalence Theorem.
This 2D companion drives the same four auction mechanisms as the 3D version — English ascending, Dutch descending, first-price sealed-bid and Vickrey second-price — through a plain canvas dashboard built for reading the numbers rather than orbiting a scene: a side panel exposes auction type, bidder count, the value distribution, round count and playback speed, bidder cards reveal each private valuation against the bid actually submitted once a round resolves, and a running revenue-history chart with a live average line lets you watch the Revenue Equivalence Theorem hold — or fail to — as efficiency and winner surplus accumulate across many rounds.
2D auction-theory lab running English, Dutch, first-price sealed-bid and Vickrey mechanisms against bidders drawn from a chosen valuation distribution, tracking average revenue, allocative efficiency and winner surplus round by round.
