  • Profits aid resource allocation
  • Direct resources to the most profitable activities

Q

Disadvantages of market system:

A

•Those with the highest incomes have most ‘money votes’
•Competition may be imperfect, so firms may gain ‘market power’ (e.g.
monopoly) and so limit consumer choice
•Externalities: some costs or benefits to society may not be reflected in
the market system as costs or benefits to private firms or individuals

Q

Advantages of planned economy:

A

•Careful planning can avoid duplication and the waste of scarce
resources
•Planned economies are often claimed to have less income inequalities
since the state owns and controls factors of production
•Excess demand need not result in price rises since prices of product
are controlled by the state

harder and to take risks

more inefficiencies

Large number of buyers
Perfect information
Homogeneous (identical) product
Freedom of entry and exit
107
Q

In perfect competition demand equals to:

A

AR=MR=P

108
Q

In perfect competition supply of firm equals to

A

MC

109
Q

All firms should produce for profit maximizing a quantity of products:

A

MR=MC

110
Q

TC in perfect competition:

111
Q

in perfect competition profit is:

A

TR-TC

112
Q

pure monopoly:

A

single firm is the industry

113
Q

non-pure monopoly:

A

more than 25% of industry output in the hands of a firm or

group of linked firms

114
Q

Momopoly characterised by barriers to entry:

A
  • Economies of scale are substantial with a high level of output required to minimise average cost
  • Sole ownership of a natural resource
  • Intellectual property rights via a patent or copyright giving the firm the sole right to produce a particular good or service
  • Whereas in perfect competition there are many sellers of an identical product, with a ‘pure’ monopoly there is a single seller of a product for which there is no close substitute
  • Legal monopoly created by the state
115
Q

disadvantages of monopoly:

A
  1. A monopolist may reduce the output and increase the price above that charged by firms in a perfectly competitive market.
  2. Monopolies are able to earn above normal profit in the long run because of barriers to entry.
  3. Such excess profit represents a redistribution of income from the consumer to the producer which can be criticized on equity grounds.
  4. Barriers to entry means that monopolies face less pressure from competition so that average costs may be higher than they need be and/or quality lower.
116
Q

In monopoly Supply =

A

MC

117
Q

monopolistic competition:

A

As with perfect competition there are a large number of firms in the market and there is freedom of entry. Unlike perfect competition each firm produces goods and services which are slightly different from those of their competitors

•The existence of such product differentiation means that firms have a certain degree of monopoly power, so that if they raise their price they do not lose all of their customers, since some consumers prefer their (differentiated) product, even at a higher price

118
Q

What are the characteristics Oligopoly?

A
  • High barriers to entry
  • Price making power by companies
  • Interdependence of firms
  • Products are differentiated
119
Q

Three possible strategic reactions in oligopoly theory

A
  • Firm assumes that its rivals will not react to changes in its strategy
  • Firm assumes that rivals will react to changes in its strategy by using their past experience
  • Firm will try to assess future reactions of its rivals by identifying the best possible move the opposition could make to changes in its strategies
120
