Incentivizing Advertiser Networks to Submit Multiple Bids

This paper illustrates a method for making side payments to advertiser networks that creates an incentive for the advertiser networks to submit the second-highest bids they received to an ad exchange and simultaneously ensures that the publishers will make more money on average in the short run as a result of adopting this scheme. We also illustrate how this payment scheme affects publisher payoffs in the long run after advertisers have a chance to modify their strategies in response to the changed incentives of the mechanism.
