4. Price Discrimination
• Discrimination: treating people differently based
on some characteristic, e.g. race or gender.
• Price discrimination: selling the same good
at different prices to different buyers.
• Examples (3 min)
• The characteristic used in price discrimination
is willingness to pay (WTP):

buyers with higher WTP.

Perfect Price Discrimination vs.
Single Price Monopoly
Here, the monopolist
produces the competitive
quantity, but charges each
buyer his or her WTP.
This is called perfect price
discrimination.
The monopolist captures all
CS
as profit.
But there’s no DWL.

Price Discrimination in the Real World
• In the real world, perfect price discrimination
is not possible:
– No firm knows every buyer’s WTP
– Buyers do not announce it to sellers
• So, firms divide customers into groups
based on some observable trait
that is likely related to WTP, such as age.
• BUT today, THINGS HAVE CHANGED!
