Q

drawback’s of monopoly power ?

A
  • high prices will lead to misallocation of resources
  • monopolies could exploit the consumers by charging higher prices
  • this will result in underconsumption, and therefore consumer wants and needs are not met
  • this loss of allocative efficiency is a form of market failure
  • production costs are high because monopolies have no incentive to become more efficient, due to a lack of competition
  • loss of consumer surplus, and a gain in producer surplus

Q

how do you determine the level of profit a firm is making from its cost curve ?

A

To determine the level of profit:

1)> identify where MC = MR (profit maximisation point) and then extend the dotted line upwards to the point where it hits the AR curve - this is your selling price

2)> Where this line crosses the average cost curve (AC) represents the cost per unit at this level of output

3)> The profit is the difference between the selling price and the average cost

Q

what are some disadvantages of pursuing profit maximisation ?

A
  • ethical and social concerns (focusing on profit maximisation can result in actions that disregard the well-being of employees, communities, and the environment)
  • risk of neglecting non-financial metrics (employee satisfaction, customer loyalty, product quality etc.)
  • Extracting the highest level of short term profits will often detract from future value creation through research or innovation

Q

why can you only profit maximise in the short run, and not in both the short and long run ? , and why does PM in the short run eat away your profits in the long run ?

A

if your profit maximising in the short run, your not using research or innovation to attempt to increase profits in the future, so this will often detract from future value creation.

  • homogeneous products
  • firms are price takers
42
Q

why are firms in a perfectly competitive market price takers ?

A

Firms in perfect competition have low market power, low market share

The firm does not have any market power so it is unable to influence the price and quantity
The firm is a price taker due to the large number of sellers
The firm’s selling price is the same as the market price

43
Q

are firms in a perfectly competitive market able to make a supernormal profit in the short run ?

A

yes

44
Q

why are supernormal profits for firms in a perfectly competitive market not possible in the long run ?

A

If firms in perfect competition make abnormal profit in the short-run, new firms are attracted to the industry
They are incentivised by the opportunity to make abnormal profit
There are no barriers to entry
It is easy to join the industry
The supply increases, and the industry price falls
The firms are now making a normal profit

45
Q

what can cause firms in a perfectly competitive market to make a loss in the short run ?

A

periods of intense competition can cause prices to fall below the average costs

46
Q

why are losses eliminated in the long run for firms operating in a perfectly competitive market ?

A

If firms in perfect competition make losses in the short-run, some will shut down
supply decreases, causing the industry price to increase

47
Q

58
Q

what are the disadvantages of oligopolys ?

  • High barriers to entry restrict the number of firms entering the market (due to high start up costs )

-High levels of spending on branding and advertising can increase production costs

59

Q

is a monopoly a price maker or taker ?

A

price maker

62
Q

what are the advantages of a monopoly to the firm ?

A

supernormal profits (reinvestment)

global competitiveness

Economies of scale (can increase, thereby lowering the average cost)

Producer surplus increases

63

66
Q

advantage of a monopoly to the consumers ?

Product innovation due to the firm’s supernormal profits may result in a better-quality product

Prices may fall If firms pass on their cost savings (due to economies of scale) in the form of lower product prices

67
Q

disadvantage of a monopoly to the consumers ?

A

A lack of competition is likely to result in higher prices as no substitute goods are available

May experience worse customer service as the incentive to improve it is limited

occurs when a firm charges different prices to different consumers for the same good/service.

78
Q

define allocative efficiency ?

A

at this point resources are allocated in such a way that consumers and producers get the maximum possible benefit.

occurs where (MC=AR)

No one can be made better off without making someone else worse off

79
Q

define productive efficiency ?

(MC=AC)

80

long-term efficiency and is a result of innovation as a firm reinvests its profits

It results in improvements to manufacturing methods

e.g. technological advancements

81
Q

the difference between the amount the consumer is willing to pay for a product and the price they have actually paid.

82
Q

what is producer surplus ?

A

the difference between the amount the producer is willing to sell a product for and the price they actually do

83
Q

is consumer surplus below or above the ME price (where demand=supply) ?

A

above, because the higher the price the greater welfare loss for the consumer (Less utility)

84
Q

below, because the lower the price the greater welfare loss for the producer (less profit)

85
Q

when the market is at equilibrium ?

A

producer and consumer surplus are maximised

86
Q

consumer surplus + producer surplus =

A

societal surplus

87
Q

in a monopoly 1………… surplus is greater than 2…………. surplus.
