Q

Why is labour supply and demand so wage elastic for low skilled and low paid jobs

A

Labour supply is highly elastic as a small change in wage would cause a large increase in workers offering themselves for work
Labour demand is highly elastic because a small change in wage will cause a large decrease in demand, because there are so many employed, so it would cost a lot more for the business

Q

Why is labour supply and demand so inelastic for high paid occupations?

A

Labour supply is inelastic due to a smaller amount of people who can work it as requires experience and training as it’s a high skilled job
Labour demand is inelastic as they are needed as they are valued highly so deserve the pay

Q

What is the cause of the backward bending supply curve?

A

A situation in which as real wages increase beyond a certain level, people will substitute leisure for paid work and so higher wages lead to a decrease in the labour supply and so less labour time being offered for sale.

Q

What is the income effect? (to do with a backward, bending supply curve)

A

A higher wage means workers can achieve a target income by working fewer hours
-ve effect : as wage goes up, you work less as you must meet you target income
+ve effect: as wage goes up, income goes up

Q

What happens when you apply a minimum wage to a monopsony?

A

In a monopsony, a minimum wage can increase wages without causing unemployment. It also won’t increase employment as the wage is already so low

Q

How does wheat farming illustrate perfect competition

A
  • one producer cannot influence the price, many sellers, homogenous products. However there will be a difference in quality so not totally perfect competition
  • many producers (200k farms in the uk)

Q

What are the three ways, monopolies form?

A

Merger or take over
Organic growth
Through acquired patent

30
Q

Why is Apple regarded as a monopoly?

A

49% market share
Huge barriers to entry : substantial capital, infrastructure costs, strategic partnerships, compliance with industry regulations.
Deals with device makers so costs are lower which makes it harder for competitors
Not homogeneous products as there is a difference in camera quality
Price discrimination, so they are price setters

31
Q

Why is Google an example of monopolistic competition?

A

90% market share
Huge barriers to entry : technological infrastructure, huge start-up costs
2 billion users, one seller many buyers
Not homogeneous as they have different features e.g image search
Price setters : freemium pricing (free, but you have to pay if you want additional services)

32
Q

What is productive efficiency and where is it on a monopolistic competition diagram

A

Producing the largest number of products and services based on the resources available (at the bottom of the AC curve) at the lowest cost

33
Q

What is allocative efficiency and where would you find it on the monopoly diagram?

A

Allocative efficiency is a characteristic of a market that performs efficiently by producing the number of goods and services that most closely resemble the demand for those goods and services.
When resources are distributed optimally.
It is when price = MC (go MC = MR first then up to the MC curve). If not operating at this point on the graph then they are inefficient

34
Q

What is dynamic efficiency?

A

Involves adapting and innovating to maintain efficiency in the face of changing market conditions, consumer preferences and technology.
It will be dynamically efficient if the AC curve moves down

35
Q

What is X inefficiency?

A

A firms inability to fully utilise its resources, resulting in higher production costs than required.

36
Q

What is X inefficiency?

A

A firms inability to fully utilise its resources, resulting in higher production costs than required. Higher costs so higher prices

37
Q

What efficiencies do monopolies have and don’t have

A

X inefficient
Productively inefficient
Allocatively inefficient
Dynamically efficient
Diseconomies of scale

38
Q

What is price discrimination?

A

Involves charging different prices to different groups for the same good

39
Q

What are the requirements for price discrimination to work?

A

Markets must have:
Different elasticities
Must be kept separate from each other
No resale
Must be an imperfect market

40
Q

Advantages to the producer of price discrimination

A

Greater revenue and greater profits
Greater investment due to greater revenue

41
Q

What are the disadvantages to the producer of price discrimination?

A

Some have a higher price causing reduction in consumer surplus
Those who pay for the highest prices may not be able to afford it

42
Q

What is an oligopoly?

A

A large number of firms in the industry, but the industry is dominated by a small number ofvery large producers

43
Q

Characteristics of oligopolies

A

Price setters -stable prices
Similarity in price
Compete on nonprice characteristics e.g quality
Dominated by a few firms
Interdependence of firms
Good’s usually highly differentiated
High barriers to entry

44
Q

What are the barriers to entry for oligopolies?

A

Economies of scale
Brand loyalty
Patent protection
Expertise and reputation

45
Q

Explain how broadband providers are an example of an oligopoly

A
  • Few dominant firms - 4 firm concentration ration is 80%
  • Interdependence - similar pricing : virgin $24/m , sky $15/m
  • barriers to entry - large economies of scale. Technological sunk costs
  • non price competition - offers free subscriptions
46
Q

What is monopolistic competition

A

NOT MONOPOLY COMP
This is an adaption of perfect competition

47
Q

Characteristics of monopolistic competition

A
  • Large number of firms in the industry
  • May have some element of control over price, due to the fact they are able to differentiate their product in someway from their rivals - products are therefore close, but not perfect substitutes
  • entry and exit from the industry is relatively easy - few barriers to entry and ext
  • non price competition
  • consumer and producer knowledge is imperfect
48
Q

Why does the long run perfect competition the AR curve return to equilibrium

A

As more firms enter or leave the market, depending on whether it’s a loss or profit in the short run

49
Q

Ways of differentiating products (non-price)

A

Quality
Product performance
Packaging

50
Q

Demonstrate how craft beer manufacturers are an example of monopolistic competition

A

Many micro-firms in the UK - 2000
Slight differential in product - some citrus flavoured
Not too many barriers to entry, but can be higher start-up costs
No dominant producer

51
Q

What are contestable markets?

A

A market in between oligopoly’s and monopolistic competition

52
Q

Characteristics of contestable markets

A
  • Firms behaviour influenced by the threat of new entrants to the industry
  • no barriers to entry or exit
  • No sunk costs
  • Firms may deliberately limit profits to discourage new entrants - entry limit pricing
  • Firms may attempt to erect artificial barriers to entry e.g lower prices until the competition decreases
53
Q

What are the barriers to entry for contestable markets?

A

Overcapacity - provides opportunity to flood the market and drive down price in the event of a threat of entry
Aggressive, marketing and branding strategies to tighten up the market
Potential for predatory or destroyer pricing
Find ways of reducing costs and increasing efficiency to gain competitive advantage

54
Q

What tactics are used by firms in contestable markets

A

Hit-and-run tactics - enter the industry take the profit and get out quickly- due to the freedom of entry and exit
Cream skimming - identifying parts of the market that are high in value and exploiting those markets

55
Q

Define contestable market

A

Where an entrant has access to all production techniques available to new firms and entry decisions can be reversed without cost

56
Q

Explain how the fast food industry is an example of a contestable market

A
  • Many burger vans and small businesses
  • low start up costs for burger vans so low barriers to entry
  • artificial barriers - som sell as low as $2
  • No sunk costs
  • 3 firm concentration ratio is 40%, others is 55%, therefore not an oligopoly as others dominates
    Eval: could be high barriers to entry as they still have to purchase the vans and high health regulations
57
Q

How does a monopsony damage consumer and producer welfare? Supply side monopsony

A
  • They use their buying power to squeeze lower prices out of suppliers - lower wages to workers
  • consumers have less choice and higher prices in the long run. If farmers and other growers leave the industry.
  • monopsony employers might use the power in the labour market to drive wages down
  • notoriously slow payers which impacts cash flow for suppliers
58
Q

What does the government do to try and control the impacts from a monopsony? Monopsony of suppliers

A

Price capping
Minimum wage
Regulation
May block mergers and takeovers
Can be inforced to pay suppliers quicker

59
Q

What is minimum efficient scale?

A

This is where all the internal economies of scale have been fully exploited
Correspond to the lowest point on the long run, average cost curve

60
Q

Example of wage differentials due to a difference in education
