Chapter 1: Industrial Organization: What, How and Why?
Problem 1
Many examples imperfectly competitive markets are possible. Common ones include: (1)
Automobiles, (2) Beer, (3) Telephone/Telecommunications, (4) Jet Aircraft, (5) Patented
Pharmaceuticals, and (6) Computer Operating Systems, .Large entry costs, scale economies,
network effects and government regulations all play a role in these examples.
Problem 2
In a perfectly competitive market, each agent is a price taker. That is, decisions of individual firm
and / or consumer do not affect the market price or environment. Therefore, there is no room for
strategic behavior in a perfectly competitive market.
Problem 3
In general, the Clayton Act was designed to prevent monopoly ―in its incipiency‖ by making
explicitly illegal a number of business practices. In particular, Section 2 prevents strategic
manipulations of the upstream / downstream market by a firm with market power. Under Section
2 of the Clayton Act, it is illegal to ―discriminate in price between different purchasers of
commodities of like grade and quality‖. Section 7 was passed to prevent anti-competitive
mergers.
Problem 4
If higher concentration leads to higher worker productivity, then industrial concentration can
lower production cost, and therefore, horizontal mergers may improve economic efficiency.
Problem 5
Market dominance by one firm may be due to the firm’s better performance, higher efficiency
etc. Price fixing, however, does not indicate higher efficiencies for the participating firms. It
simply hurts the consumers and reduces overall welfare.

Problem 2
C
Before forming the supply association, the industry price is given by P = MC. The quantity
C
supplied is Q where price is equal to marginal cost. There are no profits and consumer surplus is
C M
equal to the area adP . After forming the association and restricting supply, the price rises to P .
M c M
The quantity is Q . Producers now have profits equal to the area P cbP while consumer surplus
M
falls to abP . The deadweight loss is equal to the area bcd.
Problem 3
(a) We set price equal to marginal cost for any one of the firms to obtain

,(b) Because there are 100 identical firms, we can simply multiply the supply curve in part a by
100 as follows to obtain the supply equation.
We then solve this equation for P as a function of Q to get inverse supply
Problem 4
(a) Find the inverse demand function by solving the demand equation for P as a function of Q
Then set this equal to marginal cost to find the competitive solution. This will give
Under monopoly we set marginal revenue equal to marginal cost. We find marginal revenue by
finding total revenue first and taking the derivative with respect to Q or by applying the same
intercept - twice the slope rule to the inverse demand. Using the same intercept - twice the slope
rule we obtain mathematical concepts, their problem-solving abilities, and their aptitude for logical reasoning.3.2. Structure of Mathematics ExamsMathematics
