UNIFORM PRICING: PROFIT MAXIMUM
MR = MC
 Equivalently, set the incremental margin
percentage equal to the inverse of absolute value
of price elasticity of demand,

(price - MC) / price = -1/e
PRICE ELASTICITY
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
PRICING PRIVATE-LABEL COLA
Suppose that WalMart learns that demand for
private-label cola is less elastic than the demand
for Coca Cola. Should WalMart set a higher price
for private-label cola?

INDIRECT SEGMENT DISCRIMINATION
structure choice to earn different incremental
margins from each segment
 implementation

seller controls some variable to which segments are
differentially sensitive
 buyers cannot circumvent the variable

PURE OR MIXED BUNDLING
What is the profit-maximizing pricing policy if
 marginal cost per channel = 0
 marginal cost per channel = $5
PURE OR MIXED BUNDLING
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

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?
