9. P RICE E LASTICITY always set price so that demand is elastic if demand more elastic, then lower incremental margin percentage (IM%) e = -2  IM% = 1/2  e = -1.5  IM% = 2/3

27. P URE OR M IXED B UNDLING Generally, if item is costless, no loss from giving it to every consumer --> pure bundling; if item is costly, then should avoid providing it to low-benefit users --> use mixed bundling to screen out low-benefit users. Mixed bundling is form of indirect segment discrimination structured choice between bundle and separates

28. DISCUSSION QUESTION (A)Suppose that the marginal cost of the cable company providing a channel to the household is 0. Will you provide all channels to all types of household from the efficiency perspective? What is your profit-maximizing pricing strategy ? (B)Suppose that the marginal cost of the cable company providing a channel to the household is 50. Will you provide all channels to all types of household from the efficiency perspective? What is your profit-maximizing pricing strategy ?
