Chapter 17
Question 1. Suppose that a car dealer has a local monopoly in selling a luxury sports car. The sports car
manufacturer is considered a monopoly for its class of automobile. The dealer pays m to the manufacturer for each car that it sells and charges each customer P. Market demand faced by the dealer is given by P = 200 - Q where p is measured in thousands of dollars.
a. Suppose the manufacturer's marginal production cost per-car is $50,000 (c = 50). What will be the quantity of cars produced by the manufacturer? What will be the price m charged to the dealer and the market price P charged to consumers?
b. Calculate profits to the dealer and to the manufacturer.
c. Discuss a two-part pricing scheme that the manufacturer could use to remedy the double-
marginalization problem in its relationship to the dealer. Specifically, what will be the
price m charged to the dealer under such an arrangement and how might profits be shared
between dealer and manufacturer?
a.
Start with retailer
Π- max decision
MR = MC
200 – 2Q = m
* Q = 100 – 0.5m
This is the Π- max quantity for retailer and the demand for the manufacture
Mfg’s problem
Get m interm of Q
m = 200 – 2Q
MR = MC
200 – 4Q = 50
* Q = 37.5
This is the Π- max quantity for manufacture
m = 200 – 2Q = 200 – 2*37.5 = 125
P = 200- Q = 200 – 37.5 = 162.5
Q = 100 – 0.5m = 100 – 0.5*125 = 37.5
b.
Profit outcomes
πM = 100*37.5 – 50*37.5 = 1875
πR = 175*25 – 125*25 = 1250
c.
If the retailer and Mfg are merged together
P = 200 – Q
MC = 50
Π- max decision
MR = MC
200 – 2Q = 50
* Q = 75
* P = 125
Π = 125*75 – 50*75 = 5625
If we use 2-part pricing contract, retailer pays $m per unit to the Mfg plus a lumpsum $T
Without contract Mfg earned 1875
* Mfg needs at least this back through T
* T > 1875
Without contract retailer earned 1250
* need to keep at least this amount...
