🔨 Three Auctions, Three Strategies
Interactive 3D auction room where running simulated bidders through English, Dutch and Vickrey auction formats compares final sale price and bidding strategy differences across formats.
A 3D auction room where the same bidders, with the same private values, are run through English, Dutch and Vickrey auction rules — revealing how format alone changes the final price and who wins.
🔬 What It Demonstrates
English and Vickrey auctions are strategically equivalent — both tend to land near the second-highest private value. Dutch auctions reward shaded, below-value bidding, which typically produces a lower sale price for the seller.
🎮 How to Use
Pick a format, then watch paddles rise and fall as the price clock moves. Change bidder count and value spread to see how competition and dispersion affect the outcome, then compare formats directly.
💡 Did You Know?
William Vickrey won the 1996 Nobel Prize in Economics partly for showing that in a sealed-bid second-price auction, truthfully bidding your own value is always the optimal strategy — no guessing required.
