我们稍微修改了Ausubel-Milgrom[3]代理拍卖,增加了一个最终阶段,这可能会导致相对于“原始”拍卖的最终接受出价有一些折扣。具有最终折扣的代理拍卖是这样的,结果是在核心竞价者最优边界的一个点。那么,真实报告是一种均衡,当且仅当维克里结果处于核心时,这一条件在代理拍卖的原始版本中是必要的,但不是充分的,如一个例子所示。
We slightly modify the Ausubel-Milgrom [3] Proxy Auction byadding a final stage which possibly induces some discounts relativeto the final accepted bids of the 'original' auction. The proxy auctionwith final discounts is such that the outcome is a point in the bidderoptimal frontier of the Core. Then truthful reporting is an equilibriumif and only if the Vickrey outcome is in the Core, a condition that isnecessary but not sufficient in the original version of the proxy auctionas illustrated by an example.
