Q

Advantages of specialisation?

A

Greater variety of goods and services produced
More opportunities for economics of scale (size of market increases)
Higher output and potentially higher quality (people focus on what they are good at)
More competitive and this gives an incentive for firms to lower their costs, keeping prices down

Q

Disadvantages of specialisation?

A

Work becomes repetitive, lower motivation, affects quality and productivity
More structural unemployment (skills transferable) because workers focused on one task for so long
Higher worker turnover for firms which employees become dissatisfied with their jobs and leave regularly
Variety can decrease by producing one type of good

25
3 Cs of diseconomies of scale?
Control Coordination Communication
26
Describe diseconomies of scale in terms of control?
It becomes harder to monitor how productive the workforce is as the firm becomes larger
27
Describe diseconomies of scale in terms of coordination?
It is harder and complicated to coordinate every worker when there are thousands of employees
28
Describe diseconomies of scale in terms of communication?
Workers may start to feel alienated and excluded as the firm grows Leads to a fall in productivity Increase in average costs As they loose motivation
29
Describe the economies of scale in managerial terms?
Larger firms are more able to specialise and divide their labour Can employ specialist managers and supervisors Lowers average costs
30
Describe the economies of scale in technological terms?
Larger firms can afford to invest in more advanced and productive machinery and capital Which lowers average costs
31
Describe the economies of scale in marketing terms?
Larger firms can i code their marketing budgets across larger outputs The average cost of advertising per unit is less than that of a smaller firm
32
Describe the economies of scale in purchasing terms?
Larger firms can buy in bulk | Each unit costs them less
33
Define derived demand?
Demand for goods or services which is a consequence of demand for something else Eg demand for economics tutors is dependent on demand to study economics
34
Define composite demand?
A good that is demanded for (multiple) two or more distinct purposes
35
Define joint demand?
when demand for two goods is interdependent A good is demanded for use with another related GOOD
36
Define joint supply?
An increase in the supply of one good increases the supply of another
37
What is the formula for labour productivity?
Output / Total units of labour employed
38
Describe the division of labour?
The splitting up of complex tasks into their individual components and allowing workers to specialise in these Improving the productivity with which they can produce
39
In the short run, in general how do you increase production?
By employing more labour
40
What is difficult to alter in the short run?
Amount of land employed | Capital
41
How do you generally measure productivity?
By output per worker Or Output per worker per hour
42
What is productivity a measure of?
The efficiency of factors of production
43
What is economies of scale?
Factors which allow firms to enjoy lower average costs of production as output increases
44
Types of economies of scale?
Purchasing economies Technical economies Marketing economies Managerial economies
45
Describe managerial economies of scale?
High scale production allows firms to enjoy specialist workers who may be more efficient than those who already required to perform a wider range of tasks E.g. Division of labour
46
Describe purchasing economies of scale?
Firms ability to negotiate discounted prices when buying in bulk Some supermarkets have been criticised for abusing their power of monopoly Do this by forcing small suppliers to accept very low price see for the goods they provide them with
47
Describe technological economies of scale?
Producing on a large sale of output allows firms to be able to afford the most technologically advanced and efficient capital Due to its costs being spread out over a large number of units of output
48
Describe diseconomies of scale?
When a business gets too big for its operations | Average costs begin to rise
49
Sources of diseconomies of scale?
Communication Control Coordination
50
Due to what factor is diseconomies of scale usually found in labour intensive industries?
Human nature
51
What determines how much a firm can benefit from the economies of scale?
Strength of demand - firms will only seek to exploit economies of scale if there is sufficient demand for that level of output Nature of production - capital intensive productive processes that produce standardised products tend to benefit especially from technical and purchasing economies of scale
52
Positive XPED relationship?
Substitutes - as price goes up demand goes up
53
Negative XPED relationship?
Complements - as price goes up demand goes down
54
What good has a negative IEOD?
Inferior goods - demand falls as income rises
55
What good has a positive IEOD?
Normal goods - as consumer income rises more if demanded
56
describe external economies of scale
within an industry eh developing reaserching and development facilities in local universities spending by local authorities improving transport network
57
difference between average and total revenue
total - total flow of income to a firm for a given quantity of output at a given price average - revenue per unit (TR by quality sold)
58
what causes geographical immobility?
cost of travel distance and time taken travelling commitment at current location
59
occupational immbolity
not trained or skilled sufficiently can't move employment fields
60
what happens when two products are in joint supply?
a fall in output of one product is accompanied by a decrease in the output of another product
61
Specialisation
the production process to be split into a number of different tasks division of labour highly skilled in particular tasks
62
how specialisation leads to increased productivity
division of labour so workers are likely to become highly skilled in particular task enabling them to complete the task quicker and with better quality leading to an increase in output for the same amount of time becomes cost effective to provide the neccesary capital which wouldn't have been affordable if provided for all workers produces goods quicker so productivity increases
63
how increased productivity in specialisation leads to increased competitiveness
``` productivity increases the firm produces more units in the same time period more productively efficient fall in average costs of production firm is able to reduce price lower price than competitors increased competitiveness ```
