Q

What are the assumptions in an unregulated monopoly?

A
  • monopoly status secured by patents, economies of scale, or resource ownership

Q

Why is the demand curve of an unregulated monopoly sloping downward?

To sell more of his goods, the monopolist must lower his price

Q

Why is the imperfectly elastic firm’s MR curve below their demand curve?

A

Because monopolists must lower the prices on all units to increase sales

Q

X- inefficiency

Study These Flashcards
A

-inefficiencies or poor management by firm
-ex:
• easier work life
• giving jobs to incompetent friends/ family
• risk avoidance

20
Q

Rent seeking expenditures

Study These Flashcards
A
  • adds nothing to output
  • increases costs
  • used to maintain monopoly
21
Q

In a discriminatory monopoly what three conditions are realized?

Study These Flashcards
A
  • seller must be a monopolist or at least have some degree of monopoly power (ability to control output and price)
  • seller must be able to segment the market so that each has a different willingness and ability to pay for the product (based on different elasticities of demand)
  • original purchaser can’t resell the product or service
22
Q

Single price monopolist

Study These Flashcards
A

Produces output where MR=MC at Q and sells that Q at P.

23
Q

Perfectly Discriminating Monopolist

Study These Flashcards
A

D=MR because it doesn’t cut price on preceding units to sell more output. The profitable output is Q2, which is greater than the single monopolist

24
Q

Perfectly discriminating monopoly

Study These Flashcards
A

Collects consumer surplus

25
Monopoly price, fair return price, and socially optimum price
- Monopoly price is where the monopolist wants to produce - socially optimum price (P=MC) is where we want the monopolist to produce - fair return price is the compromise between the two
26
T/F "A monopolist always charges the highest possible price?"
False, they charge the price that will yield the highest total profit (MR=MC)
27
How does a monopoly affect consumer surplus?
A monopoly decreases consumer surplus. Surplus is transferred from consumer to producer
28
What happens to consumer surplus of a firm successfully price discriminates?
Decreases
29
What happens to the firm's profits of it successfully price discriminates?
Increases
30
What are characteristics of monopolies?
- single seller: industry and firm synonymous - no close subs: unique product; no reasonable alternative - price maker: firm exercises control over price - some degree of non price competition: generally advertising - blocked entry: barriers to entry created by monopolist or government
31
What is the market situation in a monopolistic competition?
A relatively large number of small producers are offering similar but not identical products
32
Characteristics of a monopolistic competition?
- each firm has small percentage of total market - collusion is not likely - no mutual interdependence - easy entry and exit - non price competition
33
What are the monopolistic qualities in a monopolistic competition?
- control over price - D > MR - advertising - not efficient
34
What are the perfect competition qualities in a monopolistic competition?
- large number of firms - easy exit/entry - no long term profit for industry
35
What does the demand curve faced by a monopolistic competition seller look like?
Highly but not perfectly elastic
36
In monopolistic competition is there any profit?
No there's just normal profit
37
Is monopolistic competition efficient?
No it's neither allocative or productive efficiency since P doesn't equal MC or P doesn't equal ATC
38
What are the goals of advertising?
- to increase market share | - to create customer loyalty
39
In an oligopoly how many firms are there?
Relatively small number (2-4)
40
What are the characteristics of an oligopoly?
-few large producers (2-4) -homogeneous or differentiated products -control over price with some mutual interdependence -entry barriers •economies of scale •the level of demand will dictate how many firms are needed •ownership of patents will be a barrier •ownership or control of raw materials •urge to merge for greater profit
41
What are the measures of industry concentration in a monopolistic competition?
-concentration ratio: percentage of total industry sales accounted for by the four largest firms in the industry • when 4 firms control 40% or more of the market, the industry is considered oligopolistic -herfindahl index: helps to show dominance of major firms •sum of squared % market share of all firms in the industry •greater weight given to larger firms •larger the index number, the greater the market power within an industry • 100^2 = pure monopoly
42
What does game theory examine?
Oligopolistic behavior as a series of strategic moves and counter moves by rival firms. Analyzes behavior of decision makers, whose choices affect one another.
43
What does the game theory reveal that oligopolies show?
- mutual interdependence - expectation of reaction: match price decrease but ignore a price increase - collusive tendencies - unpredictability of reaction
44
What is the economic efficiency of an oligopoly?
Acts like a monopoly; no productive or allocative efficiency; worse than monopoly because gov discourages monopoly development
45
What are the obstacles to collusion?
1. Demand and cost differences 2. # of firms 3. Cheating 4. Potential entry 5. Anti- trust laws 6. Recession
