1 Review Own price elasticity Empirical estimation of demand curve Linear and log-log modelInterpretation of coefficient and computation of price elasticity.
2 IntroductionPrice dispersion – different prices for the same product - is prevalent in the marketplaceThe “law of one price” is deadExample: Microsoft software version and upgrade pricesExample: Prices of 1/3 liter Coca-Cola cans in Germany

4 Example: Student Rates Why do software manufacturers have lower rates for students?One explanation is that they have lower willingness to pay & higher elasticity than business users.Charging two prices is more profitable
5 Example: Airline Pricing Why do airlines have “first class” rates often 2-3 times higher than cabin?There is a small group of “elite” customers who are less price elastic than “regular” customersIt is more profitable to charge two pricesThe “elites” must be “fenced in” from buying cabin seats by making cabin seats uncomfortable
6 Illustration of Benefits of Price Customization 100Demand curveGross Margins(p-c)*qpc=101000q
7 Remember the Meaning of Demand Curve The demand curve is an aggregation of the demands of individual or segment, who have different reservation prices (max. willingness to pay)Price ($)qIdeally, charge each customer their reservation price (as long as it is above c) – (i) no profitable customer is excluded from buying and (ii) no money left on table.
8 A Single Price is Inefficient Money left on the tablePrice ($)100Profit (p*-c)q*No trade – deadweight lossp*c=10q1000
9 Calculation The demand function is p = 100 – 0.1q The profit-maximizing price isThe demand at the profit maximizing price isThe profit (gross margins) isp* = (a+c)/2 = $55q* = (a-c)/2b = 450(p*-c)q* = $20250
10 Demonstration of Benefits Using 2 Price Points Rule of 1/3 for linear demand functions – 33% higher profits!100p1*p2*c1000q1*q2*
11 Calculationp = a – bqq = A – BpAssume that we can put a “fence” that prevents higher price customers from paying the lower price, also, c=$10The demand function is q= D(p) = 1000 – 10pProfit at prices p1 and p2 areThe profit-maximizing prices areThe maximized profit is(p1-c)D(p1)+(p2-c)(D(p2)-D(p1))p2* =$40, p1*=$70(70-10)*300+(40-10)( )=$27000
12 Calculationp = a – bqq = A – BpIn general, in the case of the linear demand, constant variable cost and two prices, the profit-maximizing prices arep2* = (2c + a)/3, or p2* = (2cB + A)/3Bp1* = (2a + c)/3, or p1* = (2A + cB)/3B
13 This is Price Discrimination Charging different prices to different people for the same (or similar) product.Since “discrimination” has a negative connotation, call it “price customization”A useful result - Most of the benefit of price customization may be realized with relatively few price points
14 ImplementationKey problem: How do we prevent higher willingness-to-pay customers from paying the price meant for lower willingness-to-pay customers?Place “fences” that corral customers
15 Methods of “Fence-Building” Product-line sortControlled availabilitySort on buyer characteristicsSort on transaction characteristics
16 Product-line sort Airlines – first class and economy class seats Proctor-Silex irons ($54.95 top of line model versus $49.95 same model without a LED light)Encyclopedia Britannica (Utilitarian cover, $999, Leather bound, $4000)Cars (same engine Acura $30,000, Accord $25,000)Based on impatienceBooks appear first in hardcover then paperbackMovies appear first in theaters, then in discount cinema, then in video stores

18 Sort on Transaction Characteristics Airline seats are more expensive closer to the take-off dateCD player purchased with car is more expensive than one installed laterQuantity discountsWaterBuying clubsSeason discountsIdea is that users value incremental quantities less. Alternatively, large users have good outside options hence have lower willingness to pay
19 Controlled Availability Victoria’s Secret offered catalogs with higher discounts to male consumersGM gave $1500 (nontransferable) coupons only to Oldsmobile consumers who expressed dissatisfactionManufacturers frequently negotiate better rates for larger customersFrench Telecom gave non-advertised lower prices only when subscribers called and asked, thereby revealing their price sensitivityConsumers in Japan, UK pay more for identical clothes, cosmetics, electronics than US consumers, but less for pharmaceuticalsConsider arbitrage, gray market issuesConsider fairness considerationsLegal implications
20 Sort on Buyer Characteristics Kids free/ discountFamilies with Kids are willing to pay less per person. Kids age can be easily verified (i.e., at low cost)Senior citizens discountSoftware upgrade discountCurrent users have less incentive to renew softwareStudent discountStudents willing/able to pay less

22 Price Customization Across Markets Charge higher prices at places where less price sensitive buyers purchasePrice sensitive and price-insensitive buyers naturally purchase at different locations or…Insensitive buyers will not change purchase location to take advantage of the price difference
23 Implementation of Price Customization Devil lies in the details!Specific steps of price customizationIdentify customers who are price-sensitiveGive price discount to themReduce stockpiling for those who do get discountsMake sure that price-insensitive customers do not take advantage of the discount offerDo not overstep the legal boundaries
24 Identifying the Price-sensitive Customers Which segments are more price sensitive?Personal vs. Business TravelersNew to Market vs. Experienced BuyersLight Users vs. Heavy UsersStudents/Retired vs. Employed
25 A department store has the following discounting policy for brand-name quality clothing The ticket on each item is dated and lists a number of prices.The first price is the one that a customer pays if the merchandise is bought within the first eleven days after arrival.The next price is discounted an additional 25% and applies to merchandise that is 12 to 17 days old.The third price is discounted 50% and applies to merchandise 18 to 23 days old.The fourth price is discounted 75% and applies to merchandise that is 24 to 29 days old.On the 30th day, the merchandise is turned over to charity. Since most of the merchandise is surplus, there is generally a limited supply in each style, color, and size.
26 Price Customization - Implementation What does this strategy accomplish?Describe the customers whom you suspect make up the different retail segments.A number of stores in other cities adopted this strategy for surplus merchandise, but no store had adopted it for new merchandise. Can you suggest why?For what other types of products would you consider this a profitable pricing tactic?
27 Price Customization - Implementation Peak-load pricing is used to segment markets by the cost of serving them at different times?Name types of businesses, other than public utilities, that could effectively use peak-load pricing. Describe how a peak-load strategy might be implemented in each case.Yield management represents a more sophisticated version of peak-load pricing. What kinds of companies use yield management?
28 Price Customization - Implementation A fancy steak house in a shopping mall offers a 20% discount to employees of other stores in the mall, provided that they eat before 6:00 PM or after 8:00 PMCan you explain the rationale for this strategy? (Your explanation should both account for why the 20% discount is not offered to everyone and why it is restricted in the hours when it is offered.)
29 Price Customization - Implementation A deli in a college town has an interesting pricing strategy for students. The dinner specials at the restaurant are normally $ Students, however, can buy weekly "meal tickets" that give them three meals for $13.90, 5 meals for $22.25, or seven meals for $ The tickets expire at the end of each week and they are not transferable.Can you explain this pricing strategy?
30 Price Customization - Implementation The local outlet of a fast food chain charges $2.60 for a salad from its salad bar if ordered a la carte. When ordered with a sandwich, however, the salad bar costs only $ In either case, the customers are permitted to fill their bowls just once.Can you explain this segmented pricing technique?
31 Price Customization - Implementation Most hotels will lend guests an iron and an ironing board free of charge, despite the fact that this service competes with the hotel's valet service, for which it does charge. Those same hotels usually charge outrageously to supply glasses, ice, and mixers for those who wish to have alcoholic drinks in their rooms.Can you explain this anomaly?
