Q

What did Adam Smith do?
What does this lead to?

A

He was an economist
He invented the idea of specialisation
He showed that through the division of labour worker productivity can increase.

Firms will then take advantage of this and increase productivity and lower average unit costs

Q

What are the disadvantages of specialisation?

A

Work becomes repetitive which could lead to low motivated workers and therefore this could lead to a decrease in efficiency and low retention of staff etc
Employment may become more structural as skills may nit be transferable
It could end up decreasing product variety for the consumer
Could be higher worker turnover due to the repetitive nature of the job

25
What is the long run?
The scale of production is flexible so it can be changed - all costs are variable
26
What is the marginal return of a factor?
The extra output derived per extra unit of the factor employed
27
What is the average return of a factor?
The output per unit of input. (Output per worker) ÷ time
28
What is the total return of a factor?
(The total output produced by a number of units of factors) ÷ time This amount of capital is fixed
29
Which do diminishing returns happen in. The long run or the short run? Why?
Only in the short run The variable factors could be increased in the short run. But over time the increase will become less productive so the marginal return of it falls. Then if you add another unit but it won't produce as much as the additional unit Therefore total output still rises but it increases at a slower rate Ncruncicmkdme
30
What is diminishing marginal returns linked to?
How productive labour is
31
What does the law or diminishing returns assume? Why may this not be true?
That firms have fixed factor resources in the shirt run and that the state of technology remains constant There are increases in practices such as out-sourcing meaning that firms can cut their costs and their production can be flexible
32
What does returns to scale mean?
The change in output of a firm after an increase in factor input
33
When does returns to scale increase? Give examples
When the output increases by a greater proportion to the increase in input An increase of 2 (double) unit input and 8 (quadruple) units output shows an increase in returns to scale An increase or 2 units input and 3.5 output shows an decrease in returns to scale
34
What are returns to scales linked to?
Diseconomies and economies of scale
35
What is constant returns to scale?
Where output increases by the same amount that inout increases by
36
In the short run what must be the case?
There must be some fixed costs
37
What must be the case for the long run?
All costs are variable
38
What are fixed costs? Give some examples
Costs that so not vary with output. They are indirect. Rent
39
What are variable costs? Give an example
Costs that change with output. They are direct. Raw materials
40
What is total cost? How do you calculate it?
The cost to produce a given level of output Total Cost = Total Fixed Cost + Total Variable Cost TC = FC + VC
41
What is average cost? How do you calculate it?
The cost per unit Average Cost = (Total Costs) ÷ Quantity Produced AC = TC ÷ Q
42
What is the marginal cost of production? What can we infer about this?
The cost of producing one extra unit of output We can infer, because of the law of diminishing returns, that after a point marginal cost rises as output increases
43
What shape is a short run average total cost curve? Why?
U shape Because of the law of diminishing returns. And, since the factors of production are fixed at one point employing more resources will be less productive meaning that the marginal output decreases per extra factor of production. (Marginal costs start to increase)
44
Describe and explain a long run average cost curve
U shaped At first the average costs decrease due to economies of scale until you get to the lowest point where you are at your optimum efficiency. Then average costs start to increase due to diseconomies to scale
45
What happens if factor inputs become more productive?
A firm can produce more with the same level of input so the average unit cost decreases
46
What happens if factors of production become more expensive?
Firms will usually switch to cheaper means of production (and generally more productive) factor inputs such as capital
47
When do internal economies of scale occur?
When a firm becomes larger
48
What is internal economies of scale?
Average cost of production falls as output increases (As a business gets bigger)
49
Give the examples of internal economies of scale
Really Fun Mums Try Making Pies Risk bearing Financial Managerial Technological Marketing Purchasing
50
Explain the example of internal economy: Risk bearing
As a firm gets larger they can expand their production range. Therefore, they can spread the cost of uncertainty so if one part fails they have another part to fall back on
51
Explain the example of internal economy: Financial
Banks are willing to loan money to more reliable firms. Therefore large firms may get more loan opportunities or better (cheaper) loans
52
Explain the example of internal economy: Managerial
Larger firms are more able to specialise and divide their labour. They can therefore employ specialise managers and supervisors. This may help lower average unit cost
53
Explain the example of internal economy: Technological
Larger firms can get capital intensive machinery reducing labour costs
54
Explain the example of internal economy: Marketing
Advertising is cheaper or they can do more
55
Explain the example of internal economy: purchasing
Bulk buying so the average unit cost will decrease
56
What is networking economies of scale?
The gains from the expansion of e-commerce. It makes it easier to sell as it is easy to access new customers and to display new/existing products
57
Where does external economies of scale occur?
Within an industry (Smaller scale)
58
When does diseconomies of scale happen?
When a business gets to big and the average cost of production increases
59
Why may diseconomies of scale happen?
Control Coordination Communication
60
Explain the prompt of diseconomies of scale: Control
It becomes harder to monitor workers as you have too many so productivity may decrease
61
Explain the prompt of diseconomies of scale: Coordination
It becomes harder and more complicated to coordinate through employees and different branches of a business
62
Explain the prompt of diseconomies of scale: Communication
Workers could feel alienated and unappreciated. This could lead to low moral and therefore less production, staff retention...
63
On a long run average cost curve what does the turning point represent
The LRAC (Long Run Average Costs) is the minimum efficient scale This is where the optimum level of output is since costs are at the lowest possible and economies of scale have been fully utilised
64
What is the difference between SRAC and LRAC?
Short run and Long run
65
What graph do you get when you combine the LRAC and the SRAC?
the LRAC curve
66
Describe and explain is the LRAC graph?
L shaped It shows the relationship between the SRAC curve and the LRAC curve The LRAC curve envelopes the SRAC curve. The LRAC curve is always equal to or below the SRAC curve SRAC falls at first but then increases due to the law of diminishing returns. In the long run costs change due to economies and diseconomies of scale If SRAC=LRAC the firm is operating where it can vary all factor inputs The L shape of the curve (is a development of cost theory) as it suggests that: At first costs per unit will fall as output increases due to economies of scale and because of this even if there are diseconomies of scale they will be offseted by economies of scale. This suggests that in the long run costs will continue to fall, even if the pace of falling output cost slows down (this is shown by the flat bit of the curve)
67
When does the LRAC shift?
When there is external economies of scale (when the industry grows)
68
What do we know when LRAC = SRAC?
The firm is operating where it can vary all factor inputs
69
Why is the L shape of the LRAC curve important?
The L shape of the curve (is a development of cost theory) as it suggests that: At first costs per unit will fall as output increases due to economies of scale because of this even if there are diseconomies of scale they will be offseted by economies of scale. This suggests that in the long run costs will continue to fall, even if the pace of falling output cost slows down (this is shown by the flat bit of the curve)
70
How is TR calucated
TR = Total Revenue P X Q Price X quantity sold
71
What is total revenue?
Price X Quantity sold. This is the revenue received from the sale of a given level of output
72
How do you calculate AR?
AR = Average Revenue TR ÷ Q (Total Revenue ÷ Quantity sold
73
What is average revenue?
(Total Revenue ÷ Quantity sold). This is the price each unit is sold for
74
What is marginal revenue?
The extra revenue earned from the sale of 1 extra unit. It is the difference between total revenue at different levels of output
75
What is the AR curve equal to? Why?
Average revenue curve is the same as the demand curve This is because the average revenue curve is the price of a good
76
Why may the AR curve be horizontal?
All the firms are price takers
77
What does a horizontal AR curve show?
Perfect elastic demand for the good MR = AR
78
What is profit?
The differnece between TR and TC P = TR-TC It is the reward that entrepreneurs get from taking risks
79
When is marginal revenue = average revenue
MR=AR when demand is perfectly elastic
80
What does marginal revenue measure?
MR measures the change in total revenue with respects to the change in the quantity of goods sold
81
How do you calculate marginal revenue?
MR= ΔTR ÷ ΔQ Marginal revenue = the change in total revenue ÷ the change in quantity sold
82
What is normal profit?
Normal profit is the minimum reward required to keep entrepreneurs supplying their enterprise. It covers the opportunity cost of ingesting into the enterprise and not elsewhere. T Normal profit is when TR=TC. Normal profit is considered to be a cost, so it is included in the costs of production
83
What is supernormal profit?
The profit above normal profit. So this exceeds the opportunity cost of investing. TR>TC
84
Why is profit useful in markets?
It encourages people to invest and take risks It encourages competition -Improves innovation -Improves profit -Increases efficiency Can be used as a source of cash flow for the firm It can be used as a guid of where profit can be made (for other new firms) Factors of production are usually used in markets where the rate of retuned (profit) is highest
85
What is invention?
The process of creating a new product or a new way to make a product
86
What is innovation?
The act of improving or contributing to existing products
87
Why are technological advances normally good in reference to production, productivity, efficiency and cost of production?
It can result in improvement in efficiency and productivity. This could lower costs of production for a firm The quality of goods could increase The quantity of goods produced could increase It can lead to the development of new products and markets "Creative destruction"
88
Why are advances in technology bad in reference to production, productivity, efficiency and cost of production?
It could destory market It could increase unemployment It makes it harder for small and medium sized businesses to compete - we need SMEs to create competition so innovation is encouraged
89
Who proposed the idea of creative destruction?
Schumpeter
90
What idea did schumpeter suggest?
Creative destruction This is the idea that new entrepreneurs are innovative, which challenges existing firms. This results in more productive firms making profit whilst the unproductive firms make losses and will drop out of the market. This could all result in an expansion of the economy's productive potential
91
How can technological changes influence the structure of a market?
If competition is decreased as smaller firms can't survive without machines monopolies will occur more often, and they will have less motivation on innovate due to the lack of competition. This means they will often be inefficient and their costs will be higher than they need to be. Oligopolies tend to have a higher incentive to innovate since they are earning supernormal profit and they want to keep ahead of the competition.
92
Why is technological change in oligopolies quick?
Firms are trying to get ahead of other firms to keep making supernormal profit
