This paper shows that the double marginalization problem signi cantly underestimates the ineciencies arising from vertical relations in markets where consumers who are uninformed about the wholesale arrangements be- tween manufacturers and retailers search for the best retail price. Consumer search provides manufacturers an additional incentive to substantially increase wholesale prices. Consequently, all market participants are worse o and we call this phenomenon the triple marginalization problem. We also show that, when the wholesale price is unknown, retail prices decrease and industry prof- its and consumer surplus increase in search cost, whereas the opposite is true when the wholesale price is known.
