Efficient Ranking in Sponsored Search
In the standard model of sponsored search auctions, an ad is ranked according to the product of its bid and its estimated click-through rate (known as the quality score), where the estimates are taken as exact.

متن کاملContract Auctions for Sponsored Search
In sponsored search auctions advertisers typically pay a fixed amount per click that their advertisements receive. In particular, the advertiser and the publisher enter into a contract (e.g., the publisher displays the ad; the advertiser pays the publisher 10 cents per click), and each party’s subjective value for such a contract depends on their estimated click-through rates (CTR) for the ad. ...

We also show that advertisers’ strategic behavior has not disappeared over time; rather, such behavio...
