Google/DoubleClick: The search for a theory of harmBIICL 7th Annual Merger Conference 13 NOVEMBER 2008 ANDREA LOFARO ANDREA LOFARO
OVERVIEW ANDREA LOFARO • Background on Google’s activities • Background on DoubleClick’s activities • Unilateral effects without foreclosure? • Conclusions
1.1 Background – What Does Google Do? ANDREA LOFARO • Google Sells ad space • On its own search results pages
1.2 Search advertising (sold directly) on Google.com ANDREA LOFARO
1.3 Background – What Does Google Do? ANDREA LOFARO • Google Sells ad space • On its own search results pages • On third party publishers’ websites – through its ad network • Ad networks are intermediaries that “pool” ad space made available for sale by publishers and sell this space to advertisers • Google’s ad network (mainly) offers intermediation services for two kinds of ad • search advertising • contextual advertising
1.4 Search advertising (sold via intermediation) on a partner’s website ANDREA LOFARO
1.5 Contextual advertising (sold via intermediation) on a partner’s website ANDREA LOFARO
2.1 Background – What Does DoubleClick Do? ANDREA LOFARO • DoubleClick does not sell ad space • DoubleClick sells ad serving technology for display advertising to advertisers and publishers • Once ad space has been sold by a publisher, display ad serving technology is used to deliver a display ad from the advertiser to the ad space • Display ad serving technology also plays various other supporting roles • e.g. monitors where a user went after seeing an ad
Land Rover (advertiser) pays MSN (publisher) for ad space $2 per 1000 impressions Land Rover pays advertiser-side ad serving provider (DoubleClick) 4 cents per 1000 impressions MSN pays publisher-side ad serving provider (not necessarily DoubleClick) 4 cents per 1000 impressions 2.2 Example of sale of Display advertising ANDREA LOFARO LONDON, 13 Nov. 2008
3.1 Unilateral effects without foreclosure? ANDREA LOFARO • No straightforward horizontal overlap between the parties • Ad serving and ad space are complementary products – must lie in separate markets • BUT this does not imply that unilateral effects concerns cannot arise (at least in theory) • Advertisers and publishers see text advertising and display advertising as substitutes • Commission agreed with this but left open whether substitutability is enough to justify their inclusion in same market • Complainants alleged that this created a “diagonal” relationship between Google and DoubleClick • This would make post-merger unilateral price increases profitable
3.2 Possible impacts of diagonal relationships: Merger between a steel and a zinc provider ANDREA LOFARO Iron Coal etc. Zinc Copper Brass Steel
3.3 Possible impacts of diagonal relationships: Merger between a steel and a zinc provider ANDREA LOFARO • For a merger between a steel and a zinc provider to give rise to unilateral effects, three conditions need to be satisfied : • Zinc must represent a relatively important cost in the production of brass • The zinc provider should not face effective competition from other zinc providers • Brass and steel should be close substitutes
3.4 Effects of diagonal relationship in Google/DoubleClick ANDREA LOFARO • Complainants alleged that an increase in the price of DoubleClick’s ad serving solution (zinc) would increase the total cost of display advertising (brass) • Since display advertising is a substitute for text advertising (steel), there would be some diversion of demand to Google • This diversion would be internalised by the new entity, leading to an increase in the price of display ad serving
3.5 Effects of diagonal relationship in Google/DoubleClick ANDREA LOFARO Advertisers Text advertisingoffered by e.g. Google’s Network Advertiser-side display ad server (e.g. DoubleClick) Display advertising e.g. direct negotiation between Land Rover and MSN Publisher-side display ad server (e.g. DoubleClick) Publishers
3.6 Effects of diagonal relationship in Google/DoubleClick ANDREA LOFARO Advertisers Text advertisingoffered by e.g. Google’s Network Advertiser-side display ad server (e.g. DoubleClick) Display advertising e.g. direct negotiation between Land Rover and MSN Publisher-side display ad server (e.g. DoubleClick) Publishers
3.7 Effects of diagonal relationship in Google/DoubleClick ANDREA LOFARO • Three conditions need to be satisfied in order for the concern put forward by complainants to materialise: • Ad serving must represent a significant portion of the total cost of display advertising • DoubleClick should not face strong competition within the markets for display ad serving • Text and display advertising should be close substitutes
3.8 Ad serving represents a small part of the total cost of display advertising ANDREA LOFARO • Consider the cost to Land Rover of buying 1000 impressions on MSN before and after a 10% increase in the price of ad serving • 10% increase in the price of ad serving would lead to an increase of only 0.2% in the total cost of display advertising • Difficult to see how this could trigger significant switching to text advertising
3.9 DoubleClick faces intense competition in ad serving markets ANDREA LOFARO • Display ad serving prices have fallen massively over the last 5 years • DoubleClick is forced to offer both advertisers and publishers large price reductions at the point of renewing their contracts • DoubleClick lost customers despite offering large price reductions • Any increase in the price of DoubleClick’s products would likely trigger switching to rival products and not to text advertising
3.10 Google’s solution and display advertising are not particularly close substitutes ANDREA LOFARO • Google sells text ads, DoubleClick provides tools for display ads • While these forms of advertising are substitutable, they are clearly differentiated to some extent • Therefore, Google’s solution and a display advertising solution that included DoubleClick’s technology would unlikely be considered as particularly close substitutes • Unilateral effect concern is unjustified
4 Conclusions ANDREA LOFARO • Google/DoubleClick is an important and well reasoned decision • Commission listened to the large number of complaintsb(both horizontal and non-horizontal), but it did not endorse them uncritically • Instead, it specified clearly those plausible theories of harm that could not be dismissed a priori • Challenge was to identify the key empirical questions that would allow the theories to be tested against the facts • Google/DoubleClick shows that the Commission is prepared to take a robust stance in mergers subject to strong opposition from third parties
