Career Choices
• A real estate broker wishes to hire an agent.
He posts a job offer.
• Initially, the dealer was offering 50,000 euros
a year, fixed. What was/were the problem?
• The compensation is as follows:
– The salesman gets 1% of all sales, and an
additional fixed wage of 30,000 euros.
– The average price of a house in the area is
150,000 euros.
• Who accepts the offer?
Push a little further
• What is the optimal contract?
• The real estate broker is greedy:
max Revenue – Wage.
• The productive candidate has options:
Wage >= productive broker’s outside option.
• The unproductive candidate has (worse) options:
Wage >= unproductive broker’s outside option.
• What is the optimal wage contract, assuming it is
a fixed percentage + a flat wage?

Uniform Pricing
Perfect Price Discrimination
“A key step is to avoid uniform pricing. Pricing to specific
customer groups should reflect the true competitive
value of what is being provided. No money is left on the
table...”

Spot the Difference
2. Explicit Price Discrimination
Segment the market by observable characteristics.
Charge customers in different segments different prices,
according to their elasticity.
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.
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
hopper
• Dell Inspiron 580, Base Configuration: Home:$749 Small Business:
$899
• Victoria’s secret?
Condition #3: No Arbitrage
Railroad freight pricing
U.S. railroads charge 1.5-2 times as much
to move coal as they do to move grain

2. Implicit Price Discrimination
The Mother of All Discriminatory Pricing: Airline Pricing
Airlines like to segment the market based on valuations, but
valuations are not observed
 On the other hand, valuations are correlated with time sensitivity
 In general consumers with higher valuation are less likely to accept:
• Saturday night stay
• A 14-day advance ticketing ,..etc.
 Solution: Create a product line based on artificial restrictions.
These simply annoy the customers, and have little or no
bearing on their cost of operation
Screening with Differentiated Products
Scenario: Airline has B business customers and L leisure customers.

Cost per ticket = $ 300
(Same for restricted and unrestricted tickets)
– Explicit Market Segmentation –
Pricing of Only Unrestricted Tickets
Option 1: Charge $1000 and sell only to Business travelers
Profit = (1000-300)*B = 700B
Option 2: Charge $600 and sell to both Business and Leisure
Profit = (600-300)*(B + L) = 300 (B + L)
Screening with Restricted & Unrestricted Tickets
Option 3: Charge $900 and sell unrestricted tickets to Business travelers
Charge $500 and sell restricted tickets to Leisure travelers
Profit = (900-300)*B + (500-300)L = 600B + 200L
This is Screening or Implicit Market Segmentation

Wrap Up
• Even if you cannot explicitly segment the market
don’t lose heart – implicitly segment the market!
• Offer a menu of options and try to come up with a
creative screening mechanism
• Try product differentiation, versioning, intertemporal pricing, damaging, bundling (see this
next time) – these achieve price discrimination
