Chapter 14
1.
Definitions: game theory, cooperative equilibrium, noncooperative equilibrium,
dominant strategy, weakly dominant strategy, Nash equilibrium, price leadership,
prisoner’s dilemma, oligopoly industry, sequential game
2.
Products in oligopoly markets: are they identical or differentiated?
-
Identical and differentiated
-
Could be verizon and at&t both using cell phone service which is identical
-
Cars are differentiated
3.
Identify a firm’s dominant strategy
-
Russia vs US missile construction
4.
Determine Nash equilibrium in a simultaneous game (payoff matrix) and a
sequential game (decision tree)
-
Equilibrium outcome when each player applies their best strategy.
-
Sequential game: determine best responses given prior response from the other
player.
5.
Identify examples of industries that are oligopolies
-
Airlines
-
Search engines
-
Phone service
6.
Understand relationship between P and ATC in an oligopoly industry
-
Oligopoly: P > ATC.
7.
Know the concentration ratio that indicates an oligopoly setting
-
4 firm, 40% concentration ratio.
Chapter 15
8.
Definitions: monopoly, network externality, antitrust laws
9.
Identify ways that an industry will become a monopoly
-
a) Government may block entry (patents and copyrights)
-
b) Control of key resources.
-
c) Network externalities.
-
d) Economies of scale.
10. Know motivation behind the government’s granting of patents and copyrights
-
Encourage research and development.
11. Understand relationship between monopolist’s demand curve, market demand curve,
and a monopolist’s marginal revenue curve
-
Monopolist’s demand curve = industry demand curve.

Slope is 2 times steeper.
12. Determine profit maximizing quantity of output, corresponding price and resultant
profits for a monopoly from both a graph and table

MR = MC
-
Graph: intersection between MR and MC.
-
Q* = 10
-
P* = $140
-
Profit = TR - TC = (P - ATC) x Q
-
Profit = (140 - 70) x 10
-
Profit = $700.00
13. Determine equilibrium in a graph if industry is perfectly competitive vs. equilibrium
in a graph if industry is monopolized. Understand implications for economic surplus in
one industry setting vs. the other.
-
Label equilibrium in a perfectly competitive industry.
-
Label equilibrium in monopoly industry.
-
Reduction in economic surplus
14. Identify government bodies charged with enforcing antitrust legislation
-
Federal trade commision (FTJ)

Department of Justice (DOJ)
Chapter 17
15. Definitions: marginal revenue product of labor (MRPL), compensating differentials
16. Determine number of employees that should be hired given a wage: graph
-
Continue to hire until Wage = Marginal Revenue Product of Labor
-
W = MRP (intersection point)
17. Calculate MPL, MRPL, and determine optimal number of employees to be hired
given a wage: table

The company is considering lowering the price of Model A to $27 in an effort to inçrease the
number of units sold. Based on the results of price changes that have been instituted in the
past, Tennis Products' chief economist estimates the arc price elasticity of demand to be -2.5.
Furthermore, she estimates the arc cross elasticity of demand between Model A and Model B
to be approximately 0.5 and between Model A and Model C to be approximately 0.2. Variable

Put yourself in the shoes of a CEO of these companies. Try to explain the business reasons behind the
relationships between the various payoffs (obviously, this is just an example, they may differ in the
real world and change over time). For example, why is Low in the payoff matrix the best response to
the opponent playing High? Why is the payoff from (High, High) higher for both players than from
