Pricing in position auctions and online advertising
Can search engines increase revenues by changing their position auctions? In this paper, I analyze position auctions with general pricing rules to answer this question. In these auctions, there are several items that are commonly ranked by bidders with unit demand. I show that revenues remain the same for position auctions with regular pricing rules where the price for an item depends on the bids of agents who win lower-ranked items. In addition, all of the bidders have the same ex post payoffs. I also show that regularity is a necessary condition to get ex post payoff equivalence. Copyright Springer-Verlag Berlin Heidelberg 2014
