What is productivity?
Productivity measures the efficiency of the production process.
How is productivity calculated?
Productivity is equal to output per unit of input
or
Productivity is equal to output per person employed
What are factors that can affect the productivity of the labour force?
Degree of competition in a market Advances in technology Specialization within in a business Investment in new capital inputs Investment in apprenticeships/ training to improve labour skills Quality of the management in a business Having high quality national infrastructure including transport Level of demand for a product
What demand side factors affect labour productivity?
When demand is high businesses make more intensive use of existing inputs e.g. overtime shifts
High demand creates increased profits which can then be used to fund investment in newer more efficient capital.
What supply side factors affect labour productivity?
Skills, experience and qualifications of the workforce
Speed and efficiency of infrastructure e.g. telecoms and transport networks.
What is meant by the term ‘short run’ in economics ?
Short run is when at least one of the factor inputs is fixed, in the short run businesses are constrained with fixed and variable factors.
What is meant by the term ‘long run’? in economics?
All factors of production are variable and the scale of production can also change allowing a firm to benefit from economies of scale.
What is division of labour?
Specialization of individual tasks in the production process can lead to higher output per person.
When does division of labour occur or happen?
When the production process if broken down into many separate tasks.
How can division of labour increase productivity?
As people become increasingly efficient through constant repetition of a task.
What is specialisation?
Specialisation is when a employee focuses on a specific product or task.
What are the key advantages from specialisation?
Higher labour productivity and rising business profits
Specialisation creates a surplus output of goods and services that can be traded internationally
Lower prices cause higher real incomes and gdp growth
How does specialisation increase labour productivity and business profits?
Learning by doing (specialisation) increases output per hour worked, higher productivity lowers the unit cost of supply. Increased productivity leads to higher profits for businesses.
How can specialisation result in higher real incomes and gdp growth?
Lower prices via specialisation gives consumers greater real purchasing power, higher productivity allows businesses to pay increased wages and successful specialisation contributes massively to gdp growth.
What are the disadvantages of a firm implementing specialisation?
Unrewarding, repetitive work that requires little skill can lower motivation and eventually causes lower productivity.
Workers may take less pride in work and quality suffers
Dissatisfied workers causes absenteeism to increase
People move to less repetitive jobs causing higher labour turnover and increased hiring/training costs.
Can cause structural unemployment as workers receive little training and may struggle to find employment when out of work.
How is average cost per unit calculated?
Total cost/Output
How is Average fixed cost calculated?
Total fixed cost/Output
How is Average variable cost calculated?
Total variable cost/Output
What is marginal cost?
The change in total costs from increasing output by one extra unit.
How is total cost calculated?
Cost per unit*Output
What are fixed costs?
Fixed costs are costs that do not vary at all as the level of output changes in the short run.
They have to be paid no matter the level of sales achieved.
What are examples of fixed costs?
Rental cost
Fixed salary costs
Business insurance
What are variable costs?
Variable costs are the operating costs that relate directly to the production or sale of a product.
What are examples of variable costs?
Commission bonuses Wage costs Raw materials Energy and Fuel costs Packaging costs
What are constant returns to scale?
When an increase in inputs (capital and labour) cause the same proportional increase in output.
What are diseconomies of scale?
A business may expand beyond the optimal size and see the Long Run average cost rise.
What are economies of scope?
Where it is cheaper to produce a range of products- cost savings from product diversification.
What are external economies of scale?
External economies of scale occur when a whole industry grows larger and firms benefit from lower long-run average costs.
What are increasing returns to scale?
When output is rising faster than inputs when all inputs can be varied, resulting in economies of scale.
What is minimum efficient scale?
Where international economies of scale have been fully exploited. This is the lowest point on the firms LRAC curve.
What are internal economies of scale?
A decrease in the average cost of from the long term growth of the firm.
What are examples of internal economies of scale?
Technical economies-Shipping in larger shipments
Purchasing economies-Bulk-buy
Managerial economies-Employing specialised staff to raise efficiency
Financial economies-Lower interest rates on loans for larger firms
Risk Bearing economies-Arise from product and market diversification.
In the ‘long run’ of economies what is assumed?
Costs are assumed to be variable, there are no fixed factor inputs.
What are economies of scale?
The unit cost advantages from expanding the scale of production in the long run, the effect is to reduce average costs over a range of output.
These lower costs represent an improvement in productive efficiency and can give a business a competitive advantage, via lower prices and higher profits.
How is economies of scale shown on a long run average total cost curve?
If the curve is declining internal economies of scale are being achieved.
What is the lowest point on a LRAC curve called?
The lowest point on a LRAC is called is the output of productive effiency.
What does rising LRAC mean?
Diseconomies of scale.
If LRAC is falling when output is increasing then what is the firm experiencing?
The firm is experiencing economies of scale, e.g. a doubling of the the factor inputs leads to a more than double of output.
If the LRAC is constant what is the firm experiencing?
Constant return to scale, e.g. the increase in the factor inputs is equal to the increase in output.
How do internal economies of scale occur?
The firm expands itself
Lower lrac as output increases
Increasing returns from large scale production
Benefits such as technical and financial economies.
How do external economies of scale work?
Expansion of the industry of which the firm is a member
Benefits most/all firms
Agglomeration economies are important
Helps to explain the rapid growth of many cities
What are external economies of scale?
External economies of scale involve changes outside of the business, e.g. from the expansion of the entire industry of which the business is a member. The lower unit costs for many/all firms inside the market.
What are examples of external economies of scale?
Influx of highly skilled workers
Relocation of suppliers to the center of production
What is Agglomeration economies?
Agglomeration economies or external economies of scale refer to the benefits from concentrating output and housing in particular areas.
What are the benefits that can occur from Agglomeration economies?
Good supply networks
Supply of trained workers
Infrastructure built specifically for the industry
Good transport links.
What are diseconomies of scale?
Increases in the unit cost of supply in the long run due to decreasing returns to scale.
What does diseconomies of scale mean for a firm?
A business has moved beyond their optimum size
Businesses are suffering from productive inefficiency because of organisational slack.
Worker morale can suffer which reduces productivity and increases unit cost.
Businesses may have to raise prices to cover increased costs
Lost competitiveness could lead to declining market share and a fall in the share price.
What is the minimum efficient scale?
Is the scale of output where internal economies of scale have been fully exploited.
Where is the minimum efficient scale point on a LRAC?
The lowest point on the long run average cost curve.
What is revenue?
Revenue is the money flowing into the firm it is also known as turnover.
How do you calculate average revenue?
Total revenue/Output
What does the Average revenue curve look like?
The same as the demand curve
What is marginal revenue?
The change in revenue from selling one extra unit of output.
How do you calculate total revenue?
Price per unit*Quantity
Average revenue*Output
When is total revenue maximized?
When marginal revenue=zero
When on a linear demand curve is marginal revenue=0?
Directly underneath the mid point
When marginal revenue is zero, what is the value of price elasticity of demand?
1
What would happen if marginal revenue becomes negative?
If prices were cut then total revenue would fall.
What are price takers in an economy?
Price takers accept the ruling market price and sell each unit at the same price, this is when average revenue is equal to marginal revenue.
If average revenue is equal to marginal revenue, what would the firm be in an economy?
Price taker
What are price makers?
Price makers have some pricing power in the economy.
If a firm is a price maker in the economy, what will their average revenue and marginal revenue curves look like?
Downward sloping average revenue curve with marginal revenue below it.
In what markets do price takers exist?
Highly competitive markets
Generally how much market share do price takers have?
Low percentage market share
If a price takers demand curve is perfectly elastic, then what do Average revenue and Marginal revenue=?
AR=MR
In what markets do price makers occur?
This happens in all imperfectly competitive markets.
Can price elasticity of demand vary on a straight line demand curve?
Price elasticity of demand along a straight will vary.
What are abnormal profits?
Profits in excess of normal- also known as monopoly profit.
What are marginal profit?
The increase in profit when one more unit is sold.
What is normal profit?
Normal profit is the minimum reward necessary to keep him in his present industry.
What is profit maximisation?
Profit maximisation occurs when marginal cost=marginal revenue. It is the point at which the firm is achieving the highest possible revenue.
What is profit per unit?
Average revenue-Average Total cost
What is marginal profit?
Marginal profit is the increase in profit when one more unit is sold.
How do you calculate marginal profit?
The difference between marginal revenue and marginal cost.
What is the role of profit in a market economy?
Retained profits are a key source of finance for businesses undertaking capital investment and funds for acquisitions
Market entry- Rising profits sends signals to other producers within a market
Signals about the health of the economy- Rising profits might reflect improvements in supply side performance. They are also the result of higher levels of aggregate demand during economic recovery
What is operating profit margin?
Is a measurement of what proportion of a company’s revenue is left over after paying for variable costs of production.
What is the definition of invention?
Formulation of new ideas for products or processes
What is the definition of innovation?
Practical application of new inventions into marketable products or services
How does invention differ from innovation?
Invention is the act of coming upon or finding, whereas innovation is the creating of new intellectual assets. Innovation is making changes to something established .
What is product innovation?
Launching new or improved products or services onto the market.
What is process innovation?
Finding better or more efficient ways of producing existing products, or delivering existing services.
What are sustaining innovations?
Sustaining innovations are when new products are similar or incremental to existing ones.
Give an example of a sustaining innovation?
A new version of an app or health care product.
What are disruptive innovations?
Disruptive Innovation refers to a technology whose application significantly affects the way a market or industry functions
What are examples of disruptive innovations?
Uber
Online streaming services, such as Spotify and Netflix
The development of e-commerce has had massive effect in most industries and markets, what are examples of these impacts?
Size distribution of firms Distribution channels Profitability of businesses Nature of costs in the short and the long run Barriers to entry and exit Openness to international competition.
How can innovation be a barrier to entry?
Innovation can be a barrier to entering a market e.g. property rights embedded in a product innovations protected by patent laws.
How can innovation cause the exploitation of monopoly power?
There can be a first move advantage for successful innovators that gives them scope to exploit monopoly power.
How can innovation reduce the barriers to entry?
Technology may free businesses having to rely on a single source of supply.
Businesses can build monopoly power quickly using digital platforms e.g. consider the rise of Google
How can established firms challenge new rivals such as Amazon?
Brand loyalty
Physical store network, offer click and collect
What are the objectives of businesses?
Profit Maximisation
Revenue maximisation
Sales maximisation
Social enterprises
At what output level is profit maximised?
When Marginal cost=Marginal revenue
At what output is revenue maximised?
When marginal revenue=0
At what output is sales maximised?
Average revenue=Average cost
How would a company aiming to maximise revenue achieve this?
Price discrimination
Why would a business aim to maximise sales revenue rather than profits?
Because it wishes to deter the profitable entry of new firms/rivals into an industry and therefore maintain more market power.
What may be a consequence if a business decides to maximise sales revenue rather than profits?
A reduction in the price of the firm’s shares since operating profit is likely to be lower.
What is sales maximisation?
When a business sells as much as possible without making a loss.
What is a 3 firm concentration ratio?
The value of the highest three businesses’s market shares added together.
How does profit maximisation affect stakeholders?
Firm makes highest profit thus benefiting the shareholders, as potentially more dividends or increase in share value.
How does profit maximisation affect consumers?
Higher prices and lower output lead to a lower level of consumer surplus
How does profit maximisation affect wider community stakeholders?
Profits provide funds for investment and more tax revenue for the government
How does sales revenue maximisation affect shareholders?
Profits lower than profit max so less shareholder dividends
How does sales revenue maximisation affect consumers?
Lower prices than with profit maximisation so a gain in consumer surplus
How does sales revenue maximisation affect wider community stakeholders?
Likely to be nearer allocative and productive efficiency at a lower price and higher output thus community/society benefit.
How does sales maximisation affect shareholders?
Only normal profit is earned so shareholders recieve lower dividends.
How does sales maximisation affect consumers?
Prices are lower than profit max so customers benefit.
How does sales maximisation affect wider community stakeholders?
Average revenue is equal to average cost thus firm maximizes output which may benefit employment at the firm.
What are maximisers?
Maximisers behave in traditional way and always try to make the best possible choice from all available alternatives.
What are satisficers?
Satisficers examine only a limited set of alternatives and choose the best option between them.
When do some firms use simple rules of thumb for pricing policies?
If a business adopt satisificing, they may use simple pricing methods rather than complex pricing methods,
e.g. cost plus approaches.
Give an example of a possible satisficer and their motive?
Managers of a business who are more concerned with increasing sales revenue/ market share instead of seeking pure profit maximisation.
What are some examples of perfect competition?
Wheat
Sporting Bets
What are the key assumptions to assume that a market is perfectly competitive?
Homogeneous products
All firms have access to factors of production
Large number of buyers and sellers
No barriers to entry or exit
Perfectly elastic demand curve
Perfect knowledge for buyers/sellers
Profit maximization is assumed as the key objective of firms
Consumers are assumed to be utility maximisers.
Price taker
If firms are making abnormal profits in the short run what occurs in the economy?
Encourages the entry of new firms into the industry
Creating an outward shift in market supply
The increase in market supply will eventually reduce the market price until price=LRAC
What is allocative efficiency?
In both the short and the long run price is equal to marginal cost and thus allocative efficiency is achieved.
No one can be made better off without making some other agent at least as worse off.
What is productive effiency?
Productive efficiency occurs when the equilibrium profit maximising output is supplied at the minimum average cost.
If a firm is producing at the lowest point on their LRAC it means the firm must be productive efficient.
What is dynamic efficiency?
There is little scope for innovation designed to make products differentiated from each other and allow one or more suppliers to establish some monopoly power.
What is the ‘shut down price’?
The shut down price is the minimum price a business needs to justify remaining in the market in the short run.
What is the shut down price in the short run?
When price is of sale is greater than the average variable cost.
In the long run a business needs to make at least what type of profit to justify remaining in an industry?
At least normal profits. E.g. where Price is equal to Average cost
If a firm is making a loss in a market while may they still continue to operate?
Downturn is seen as temporary
Managers are satisficing
