Answer 5

The unit cost advantages from expanding the scale of production in the long run.

Question 6

Economies of scales exist when?

Answer 6

Long run average costs fall as output rises.

Question 7

What do lower costs represent?

Answer 7

Improvement in productive efficiency and gives a business a competitive advantage

Question 8

If the long run average total cost curve is declining then what is being expolited?

Question 11

What is specialisation of the workforce as a technical economies of scale?

Answer 11

Larger firms can split the production processes into separate tasks to boost productivity

Question 12

What is law of increased dimensions as a technical economies of scale?

Answer 12

Doubling the height and width of a tanker or building leads to a more proportionate increase in cubic capacity

Question 13

What is learning by doing as a technical economies of scale?

Answer 13

The average cost of production decline in real terms as a result of production experience as a business cuts waste and finds the most productive means of producing output on a bigger scale.

Question 14

What is purchasing economies?

Answer 14

A large firm can purchase factor inputs at bulk in lower prices if it has monopsony power

Answer 18

When a whole industry benefit from lower long-run average costs

Question 19

Answer 19

If firms locate to a similar area, this makes it more efficient for suppliers to meet a larger base of purchasers

Question 20

What is skilled labour as a factor of external economies of labour?

Answer 20

Answer 21

-Cluster effect
-Skilled labour
-Transport links
-Supportive legislation

Question 22

What are diseconomies of scale?

Answer 22

Increases in the unit cost of supply in the long run due to decreasing returns to scale

Question 23

Diseconomies of scale mean what?

Answer 23

-Businesses moved beyond optimum size
-Businesses suffer productive inefficiency
-Breakdowns in communication
-Workers’ morale can suffer reducing productivity increases unit costs
-Lost competitiveness lead to decline in market share

Answer 24

-Control and communication problems
-Co-operation problems

Question 28

What is the minimum efficient scale (MES)?

Answer 28

The scale of production where all of the internal economies of scale have been fully exploited

Question 29

What does the minimum efficient scaled correspond to?

Answer 29

The lowest level of output at which the lowest point on a firm's long run average cost curve is reached.

Question 30

In a natural monopoly the minimum efficient scale (MES) is likely to be what?

Answer 30

High

Question 31

MES is likely to be low relative to what?

Answer 31

The size of market demand in a very competitive industry

Question 32

What are the 3 causes for why a business will have high minimum efficient scale (MES)

Answer 32

-MES is high when fixed costs of setting up production are large. -MES is high when marginal cost of supplying extra customers is low relative to foxed costs. -Natural monopoly LRAC may fall across entire range of output which means that the MES is very high % of total market demand

Question 33

What are examples of markets with a high MES?

Answer 33

-Water, gas and electricity supply -Underground transport systems -Social networks and search engines

Question 34

What are example of markets with a low MES?
