Q

What is specialisation?

A

Where an individual, firm, region or economy vconcentrates on a narrow range of task, producing excess for individual needs and then trading the excess for those goods and services which they no longer produce.

Q

What is division of labour?

A

linked to specialisation and is where a firm decides whether to break down the job of making a complex product in to a number of simpler, constituent parts such that individual workers are sable to specialise and become more of an expert in their particular task.

Q

What are the benefits of the division of labour?

A

Workers are able to quickly gain a high level of skill in a limted range of tasks.
Workers can specialise in areas which they enjoy or are expert
Time-savings as workers don’t need to use multiple different tools
Reduces the level of capital investment requires as tools requires to do a specific task are only given to the worker with that specific task./

Q

What are the gains you can get from specialisation?

A

Higher output per unit of input
Quality improvements due to expertise in terms of the product, delivery times or customer service
lower cost per nit- greater competitiveness due to lower prices and higher profit margins.

Q

What are some of the problems with specialisation?

A

Tasks can become tedious and monotonous.
Workers may end up feeling that they cant be bothered which may result in lower quality and higher levels of absenteeism.
The market may not be large enough to sustain high levels of specialisation.
If one area becomes too specialised then should a particular industry decline then workers can be left with no work-structural unemployment.

Q

Why is increasing productivity important?

A

More output from the same or less inputs= lower average costs
lower average costs= higher profits, or lower prices
lower prices= greater competitiveness locally and/or even internationally.

Q

Why is the AC curve u-shaped?

A

Initially AC will fall as the firm produces more goods up to the point Y. This is because it is using its inputs more efficiently.
After point Y, AC will rise as inputs start to lose efficiency.

Q

If average costs are reduced (economies of scale) what can firms do?

A

Either
- make higher profit per unit sold
OR
-lower prices (maintaining profit per unit) and become more price competitive.

25
Q

Why is the AFC (average fixed cost) curve always falling?

A

Falling at an increasingly slower rate because costs will decrease with higher output as cost per unit has decreased.

26
Q

Why does the AVC (average variable cost) curve have a lower turning point than the AC curve?

A

AC turning point higher than AVC turning point because increasing AVC must be higher than AFC before AC can rise.

27
Q

What is average revenue?

A

The average value of receipts from selling a unit of output.

28
Q

How is average revenue calculated?

A

Total revenue/ quantity sold

29
Q

What is total revenue?

A

The total amount of money recieved from the scale of a given quantity of output.

30
Q

How is total revenue calculated?

A

selling price per unit x quantity sold

31
Q

What is profit?

A

Total revenue - total costs

32
Q

Where does productive efficiency occur?

A

At the lowest point on the average cost curve where AC is minimised.
When an economy is producing on the PPF curve.

33
Q

What are economies of scale?

A

The fall in Long Run Average Costs of Production as the scale of the firm increases.
(+ the advantages which a firm gets from being big)

34
Q

What is the definition of the short run?

A

The period of time during which at least ONE factor input to the production process is fixed.

35
Q

What is the definition of the long run?

A

The period of time during which ALL factor inputs to the production process are variable.

36
Q

When do managerial economies of scale occur?

A

When companies can afford specialists who can more effectively manage particular parts of the business.

37
Q

What are the advantages of a managerial economy of scale?

A

Specialised staff and leaders can innovate, inspire, cut costs and give firms direction.
This should increase quality and lower costs per unit.

38
Q

When does a technical economy of scale occur?

A

When a firm is able to use its machinery and equipment more efficiently and spread its fixed costs as it grows in size

39
Q

What are the advantages of a technical economy of scale?

A

Using larger capacity machinery which reduces average costs.
Bigger firms use all of their equipment all the time meaning they are more efficient than small firms who can’t use it all of the time.
R&D costs can be spread over a larger number of units (e.g. car development)

40
Q

When does a purchasing/marketing economy of scale occur?

A

Larger businesses can afford to bulk buy
larger businesses can afford more advertising campaigns etc.

41
Q

What are the advantages of a purchasing/marketing economy of scale?

A

Make profit through volume.
Higher volumes leads to discounts- if a discount is not offered to larger companies they will seek a competitor.
Total marketing costs are spread out over a larger amount of output leading to lower costs per unit.

42
Q

What is a risk bearing economy of scale?

A

When companies operate globally in order to spread their risk against recessions etc.

43
Q

When does a financial economy of scale occur/

A

When larger firms are able to borrow larger sums of money, and are more likely to be lent to as they are less risky than smaller firms.

44
Q

What are the advantages of a financial economy of scale?

A

The larger amount of money you borrow and the lower the risk, the lower the rate of interest you will pay.
Lower cost per £1 borrowed.

45
Q

What are diseconomies of scale?

A

When a firm gets to a scale where they are impossible to manage efficiently leading to rising average cost per unit.

46
Q

Why do diseconomies of scale arise?

A

Workers feel alienated
Communication becomes slow and efficient
Decision making becomes slow and efficient.

47
Q

What is the definition of external economies of scale?

A

Economies of scale, represented by a downward shift of the average cost curve, which arise from a growth in the size of the industry in which the firm operates.

48
Q

What are some examples of external economies of scale?

A

Improved local infrastructure
Pool of locally available skilled labour
Plentiful supply of locally based support services
Government assistance for large industry that is not available for a small industry (e.g. for export contracts)

49
Q

What will external economies of scale have on the LRAC (long-run average cost) curve?

A

They will cause the LRAC curve to shift downwards

50
Q

What is the primary source of external diseconomies of scale?

A

Where a growing industry, competing for the available factors of production, causes the price of factor inputs to rise - (demand exceeds supply).

51
Q

What effect will external diseconomies of scale have on the LRAC curve?

A

They with cause the LRAC curve to shift upwards.

52
Q

What is the short run?

A

the period of time over which at least 1 factor input is fixed.

53
Q

What is the long run?

A

the period of time over which all factor inputs are variable.

54
Q

What is does the law of diminishing returns state?

A

if increasing quantities of a variable input are combined with a fixed input, eventually marginal and then average output (product) of that variable input will decline. Diminishing returns are said to exist when this decline occurs.

55
Q

When do increasing returns to scale exist?

A

if the percentage increase in output is greater than the percentage increase in all factor inputs.

56
Q

When do constant returns to scale exist?

A

if the percentage increase in output is equal to the percentage increase in all factor inputs.

57
Q

When do decreasing returns to scale exist?

A

exist if the percentage increase in output is less than the percentage increase in all factor inputs.

58
Q

What is marginal output (product)?

A

the addition to total output from 1 more unit of variable input.

59
Q

What is average output?

A

the average amount of output from each unit of variable input.
