(game theory) A non-zero-sum sequential game designed to illustrate a paradox brought about by traditional rational-choice theory in which players are compelled to make an ultimately irrational decision based entirely on a sequence of apparently rational choices made throughout the game. It involves an auction for a dollar bill where the second-highest bidder loses the amount that they bid, making them the biggest loser in the auction.

日本語の意味
（ゲーム理論） 伝統的な合理的選択理論によると論理的な決定が連続して行われるはずであるが、実際には参加者が非合理的な判断を強いられるという逆説を示すために設計された非零和の逐次ゲーム。具体的には、1ドル紙幣の入札において、第二位の入札者が自分の入札額を失うため、最終的に最も大きな損失を抱えるという特徴がある。
