2. 3-Minute Case Study: “How Advertisers Can Use Your Personal Information to Make you Pay Higher Prices” & “Why Some People Pay More Than Others When Shopping Online”
How would a businessman/woman react to these articles?
How would the average consumer react to these articles?
Are the actions being taken by these firms socially responsible?

3. Price discrimination as a tool for social benefits/allocative efficiency?
Consider the following…
Doctor’s Office services 4 patients: 3 value the treatment at $5, while the 4th, and rich, patient values treatment at $8
Doctor’s Offices FC are $5 and MC of treating 1 patient is $4
If one uniform price of $5 is charged, all patients will receive treatment; however, TR<TC (TR = $20 and TC = $21 = )
The Doctor will not offer treatment!!!
But, if price discrimination is possible, all patients will pay based on their willingness to pay…
TR = $23 ($8 + $5 + $5 + $5) and TC = $21  Doctor will treat all patients and stay in business!

9. 1st Degree Price Discrimination Illustrated: Key Concepts
Wait?!? Isn’t that new P/Q combination also the socially optimal P/Q (MC = P)???
It sure is! Our price discriminating monopoly is now allocatively efficient.
1. When monopoly can make each consumer pay exactly their WTP the marginal revenue function of the firm changes….MR = D = AR = P.
When MR changes, so does profit maximizing quantity (MR =MC rule)! Q

10. 1st Degree Price Discrimination Illustrated: Key Concepts
So, profits have increased…
the monopolist is happy.
But, quantity has increased…
