Q

what is the rationing function?

A

Q

How do market economies allocate resources?

A

The price mechanism distributes resources at equilibrium where the consumers who are willing to purchase a good is equal to firms who are willing to produce it. This is what Adam Smith cals the invisible hand.

Q

What is an example of a quasi public good?

A

Q

Why might the existence of public goods result in the free rider problem?

A

Since public goods are both non-rival and non-excludable, a non-purchaser may benefit from the good as much as someone who payed for the provision of the good. Therefore, a rational economic agent would free ride and gain all the utility of the good for one of the cost. However, if everyone does this, the good will not be provided at all.

Q

What are the assumptions underlying profit maximisation as a business objective?

A

assumptions underlying profit maximisation as a business objective?
It is based on the assumption that all firms have perfect knowledge not only about their own costs and revenues but also of other firms. It is also based on the assumption of rationality that firms will only concern themselves with profit.

Q

Why might profit ,maximisation be relevant to a business?

25
Q

What is a variable input?

A

Any resource that can easily vary with a change in the quantity of output in the short run. For example: cotton for manufacturing t-shirts.

26
Q

What is the relationship between average costs and output?

A

there is an inverse relationship since an increase in output enables the employment of more factors of production and more economies of scale. After a while these economies of scale will become diseconomies of scale, however.

27
Q

What are internal economies of scale?

A

Internal economies of scale are falling long-run average costs associated with an increase in output for an individual firm.

28
Q

What are external economies of scale?

A

conomies of scale shared with rival producers as a result of the industry being large.

29
Q

What are the causes of internal economies of scale?

A

An increase in output.

30
Q

What are the causes of external economies of scale?

A

External economies of scale happen because of larger changes within the industry, so when the industry grows, the average costs of business drop

31
Q

What is technical economies of scale?

A

The fall in average cost a firm incurs from the increased use of large scale machinery due to increased output

32
Q

What are managerial economies of scale?

A

The larger the scale of a firm, the greater its ability to benefit from specialisation and division of labour in management.

33
Q

What are marketing economies of scale?

A

Larger firms have a lower unit cost of advertising. TV and billboard ads are worthwhile for big firms but too expensive for smaller firms

34
Q

What are financial economies of scale?

A

Larger firms can often borrow money at a lower rate of interest - lending to them is seen by banks as less risky.

35
Q

What are the internal economies of scale?

A
  • technical
  • managerial
  • marketing
  • financial
  • purchasing
36
Q

What are purchasing economies of scale?

A

When a business bulk buys supplies at a discounted rate which means that the cost per unit decreases.`

37
Q

What are infrastructure economies of scale?

A

Higher settlement density for firms means that infrastructure built in that area is more cost effective. This may reduce unit costs.

38
Q

What are the characteristics of a monopoly?

A
  • High barriers to entry/exit
  • one firm (in practice just a 25% market share)
  • price making power
39
Q

is a monopoly productively efficient?

A

No. A monopoly is productively inefficient because the output does not occur at the lowest point on the AC curve.

40
Q

What is productive efficiency?

A

a situation in which a good or service is produced at the lowest possible cost

41
Q

What is allocation efficiency?

A

A situation in which a good or service is distributed in the most efficient way, where there is no excess supply or demand.

42
Q

What is dynamic efficiency?

A

A situation where both productive and allocative efficiency can be improved in the long run via the redistribution of resources into research and development. Supernormal profits may be invested into finding less costly methods of production.

43
Q

What is a natural monopoly?

A

A natural monopoly occurs when the most efficient number of firms in the industry is one.

44
Q

What is price discrimination?

A

the action of selling the same product at different prices to different buyers, in order to maximize sales and profits.

45
Q

Do monopolies have x-efficiency?

A

No. low competitive pressure may cause organisational slack where the factors of production aren’t efficient and average cost will sit above the AC curve.

46
Q

What are the advantages of a monopoly?

A

Supernormal profit/Economies of Scale/Price discrimination/Career progression

47
Q

what are the disadvantages of a monopoly?

A

Allocatively and productively inefficient
- Higher prices
- lower quality
- Inequitable distribution of income

48
Q

What are the characteristics of an oligopoly?

A
  • five firm concentration rate of over 60%

A group of firms openly agree to control the price and output of a product for instance: OPEC

52
Q

What is product differentiation?

A

  • Dynamic efficiency due to price making power.
  • The kinked demand curve means prices largely remain stable but if one firm cuts price others must follow or leave the market. This benefit consumers.
56
Q

  • may not be productively efficient
  • not allocatively efficient
