我们研究一个拍卖设计问题,拍卖师预期投标人串通默契。我们以如下方式对默契共谋进行建模:无论拍卖人宣布哪一次拍卖,它都成为相应重复博弈的阶段博弈,在由此产生的重复博弈的所有序列均衡中,投标人都选择最大化其事前支付总额的均衡。我们表明,在这个模型中的最优拍卖的形式是一个公共物品提供游戏。
We study an auction design problem where the auctioneer anticipates that bidders collude tacitly. We model tacit collusion in the following way: whichever auction the auctioneer announces, it becomes the stage game of a corresponding repeated game, and out of all sequential equilibria of the resulting repeated game, bidders play the one that maximizes their total ex ante payo. We show that an optimal auction in this model takes the form of a public good provision game.
