Abstract

I describe how search engines sell ad space using an auction. I analyze advertiser behavior in this context using elementary price theory and derive a simple way to estimate the producer surplus generated by online search advertising. It appears that the estimated value of online advertising tends to be between 2 and 2.3 times advertising expenditures. JEL: D44 (Auctions), D21 (Firm Behavior)
