McDonald’s “Behind the Arches” John F. Love
Ray Kroc Founder of the
McDonald’s franchise
“ He soon realized that while McDonald’s might not produce a windfall for the franchiser, it could be a lucrative proposition for the franchisee.[…] Capital investment in those operations typically started at $250,000, but an early McDonald’s – including land, building, and equipment – could be opened for as little as $80,000. When the franchisee found a landowner willing to rent the space to him and a bank willing to provide a mortgage on the building, his investment amounted to no more than the $30,000 needed for the equipment, the sign, the start-up inventory, and even that could be borrowed.” […] “The Rolling Green group was arguably, from McDonald’s point of view, the worst collection of McDonald’s operators in the chain’s thirty year history.”
“[…] what irritated Kroc the most was when Dondanville raised his hamburger price from 15 to 18 cents.[…]”
“Dondanville justified it on financial grounds; like most other early McDonald’s units in California, the Reseda store was barely breaking even, and Dondanville was becoming desperate. `We ate hamburgers at home for 27 days in a row, and we got sick of it [sic],” Dondanville recalls. `That’s when I decided to raise prices.’”
What’s going on??
[…] “Ray was very much against remote control.” […]

You can now answer this
You write a self-help book called `Five steps to have more free time.’
You sign a contract with a book publisher:
• You get a lump sum of $100,000 plus 7% of the wholesale value of all sales of the book.
• The publisher has a fixed production cost of $200,000 (inc. $100,000 royalty) for the book, plus a cost of $5 per copy for printing and distribution.
• Each party (you, the author, & the publisher) cares about only her/his profit for this book’s sale.
Each party has a preferred price. Which one is higher?

Heaven: Perfect Price Discrimination
! World-wide, every year, governments sell multiple trillions of dollars worth of securities to bank and large institutional investors. ! Banks’ willingness to pay for particular security depends on its portfolio needs and information about the state of the economy
… banks differ along these two dimensions ! A bank’s valuation is private information: it is not known to the government
How should governments sell securities to maximize revenues?

How does Priceline’s business model addresses the fundamental problem of price discrimination: ! Consumer identification: Ask consumers to name their own price! Consumers give some information about their valuation. Does this really achieve some PPD?? ! Captures only part of the remaining consumer surplus: Make obtaining the discounted products such a pain in the #&& in order to discourage high-valuation buyers from switching (this is necessary to convince sellers to use Priceline’s site).
Priceline.com: « Name your own price » also known as opaque pricing
• Perfect price discrimination is a useful benchmark, but never achieved in practice. • Informational problem: It is very difficult to know the valuation of a
customer.
• However: it should not lead you to revert to uniform pricing. • You may partially achieve the goal of PPD. �Exotic pricing strategies !!
• Today: Explicit market segmentation. Take a market, divide it into segments, and charge a different price for each segment.
• Session 8: Implicit market segmentation.

Explicit Market Segmentation
Condition #1: Market Power • Must have ability to set prices
Condition #2: Observability (No deception)
• Use an easily observed trait which is correlated with elasticity of demand. • Customer cannot masquerade as someone else.
Condition #3: No arbitrage/resale • Customers from one segment cannot sell good to others.
Segment the market by observable characteristics. Charge customers in different segments different prices, according to their elasticity.
Explicit Price Discrimination - Condition #2: Observability • Tourists pay more for kilims in Istanbul than locals. • Students get discounts on air/rail tickets. • Californians pay $97; non-Californians pay $151 for a 2-day park

GSK wins battle in ‘parallel’ drugs caseBy Tobias Buck in Brussels and Andrew Jack in LondonPublished: September 27 2006 19:52 | Last updated: September 27 2006 19:52
GlaxoSmithKline on Wednesday won a potentially far-reaching victory in a long-running legal battlethat has pitted Europe’s pharmaceuticals industry against competition regulators and traders that shipdrugs between European Union member states.
GSK has long tried to curb “parallel trading”, which involves the shipment of drugs from low-costcountries, including Spain and Greece, to countries such as Britain and Germany, where the price ofmedicines is fixed at higher levels.
Parallel trade accounts for about 5 per cent of Europe’s !80bn ($101.6bn, £54bn) pharmaceuticalsmarket, and is growing fast. In Britain, the traders account for almost a fifth of the market.
The drugs industry argues that such arbitrage undermines their incentive to invest in research anddevelopment. But parallel traders say exploiting price differences helps national health providers savemoney, and must be allowed under the terms Europe’s internal market.
The European Commission, the EU’s top antitrust regulator, in 2001 ruled that the curbs GSK imposedon parallel traders in the Spanish market violated EU competition rules.
On Wednesday, in the European Court of First Instance, that decision was partially annulled. The EU’ssecond highest court found that the Commission had failed properly to consider the specific nature ofthe industry, in which prices are determined more by government intervention.
The Commission was also told to pay more attention to the effect that parallel trade may have oninnovation.
Lawyers and antitrust experts said it was the first time a court had acknowledged the special characterof the drugs industry.
However, some in the parallel trade industry stressed that the judges had upheld the Commission’sfinding that GSK’s actions had restricted competition.

Explicit market segmentation means . . . not all customers have same trading opportunities.
Which of the following are examples of explicit market segmentation? 1. Child, student, and senior-citizen discounts.
2. Different airline economy class prices for flights with a Saturday night stay.
3. Different prices for medicine in different countries or for different uses.
4. Different utility rates for residential and business customers.
5. Academic discounts on hardware/software.
6. Coupons that can be redeemed by mailing them in.

Roxy Theater: The Question
• “Several members of the management team want to eliminate excess demand by eliminating the student discount. After all, they note that it is the increase in student demand that is causing the excess demand problem.”
Roxy Theater
Does the manager�s forecast make sense that student demand will average 33 seats per showing? ! No! Fall in demand for general public due to VCRs. Students own VCRs too. ! % change in general public demand = (80 – 96)/96*100 = 16.7%
! Worst-case scenario: Student demand in 1997 = 33*(1-0.167) = 27.5
! Public demand in 1998 = 80*0.967 = 77.4 Student demand in 1998 = 27.5*0.967 = 26.6
! Total demand = 104 < 113. But still more than capacity (95)
! At the profit-maximizing price, the theater is either at- or under- capacity.
! Partial conclusion: The price of $6 for all should be increased.
Student Discount in Roxy Theater
Roxy can sell out at $6. So is student discount necessary? Should Roxy eliminate student discount and charge $6 to all?
Explicit Market Segmentation
Agree: Es > EGP (as in the past) Recall MR = P(1-1/E) So if same price (say $6) MRS > MRGP Same price: MRs ≠ MRGP → profits are not maximized To equate: sell more to students; less to general public till MRs = MRGP Cut prices to students from $6; Raise prices to General Public above $6 Lessons: ! Do not focus on eliminating excess demand ! Do not ignore other market segments ! Price to maximize profits ! Segmenting market and price discrimination can raise profits

Wrap up – Explicit market segmentation
Main point 1. Perfect price discrimination captures the entire consumer surplus…
but charging a different price to each customer is hard! 2. Charge different prices to different groups of customers identifiable with
observable characteristics. • Charge a higher price in the market segment with less elastic demand. • Condition #1: Market Power • Condition #2: Observability (no deception). • Condition #3: No arbitrage.
