Q

Describe a planned economic system

A

The state (government) makes the decisions about what to produce, how to produce (through directives), and who to give it to( by deciding workers’ wages and controlling the price).

The state owns the land, and capital and employs workers.

Necessities like housing, transport, education are all free of cost or extremely cheap

Q

Describe a market economic system

A

Government intervention is minimal and the land and capital is privately owned

Consumers decide what to produce and signal producers through price mechanism

Private firms decide how to produce the product (seek the lowest production cost but high quality)

Maximum influence over the market is influenced by whoever earns the most income, the most skilled, have more demand.

Q

Role of price mechanism

A

It acts as a sort of incentive for producers to respond to changes in market conditions (demand and supply)

Higher demand for a product typically means consumers are willing to pay more for it, this profit encourages firms to produce more of that product.

It also rations out products when the supply falls short of demand. The prices normally rise to lead to a reduction in demand as only people that can afford it will consume it.

Q

What 2 pieces of information are provided by PED?

A
  1. Sign: This tell us that there is an inverse relationship between the quantity demanded and price – a rise in price will cause a contraction in demand and a fall in price will cause an extension in demand. (Minus)
  2. Size of the figure. This indicates the extent by which demand will extend or contract when price changes. A figure of –2, for example, indicates that a 1% change in price will cause a 2% change in quantity demanded.

41
Q

Describe elastic demand

A

Elastic demand occurs when a change in price results in a greater percentage change in quantity demanded, giving a PED figure (ignoring the sign) of more than 1, but less than infinity.

When demand is elastic, price and total revenue move in opposite directions.

In the case of elastic demand, a firm can raise total revenue by lowering the price, but it must be aware that if it raises the price, its total revenue will fall.

42
Q

Describe inelastic demand

A

Inelastic demand is when the quantity demanded changes by a smaller change than the price and the PED is less than 1, but greater than zero.

In this case, price and total revenue move in the same direction.

If the price is raised, the quantity demanded will fall, but by
a smaller percentage than the change in price and hence more revenue will be earned. If the price is lowered, more products will be demanded, but not enough to prevent the total revenue from falling. In this case, if a firm wants to raise revenue, it should raise its price

43
Q

Determinants of elasticity

A
  • the availability of substitutes of a similar quality and price
  • proportion of income spent on the product
  • whether the product is a necessity or a luxury ( what were once seen as luxuries can turn into necessities as people become richer. )
  • whether the product is addictive or not
  • whether its purchase can be postponed
44
Q

Define-
Perfectly elastic demand
Perfectly inelastic demand
Unit elasticity of demand

A

Perfectly elastic demand: when a change in price causes a complete change in the quantity demanded.

Perfectly inelastic demand: when a change in price has no effect on the quantity demanded.

Unit elasticity of demand: when a change in price causes an equal change in the quantity demanded, leaving total revenue unchanged

45
Q

PED + Total revenue relationships

A

Elastic- Opposite direction

Inelastic- Same direction

Perfectly Elastic- Rise in price will cause demand to fall to zero

Perfectly Inelastic- Same direction, but also by the same percentage

Unit Elasticity- Price and the quantity demanded change by the same percentage and so total revenue remains unchanged.

46
Q

Why would consumers benefit from a product being elastic?

A

This is because producers would be reluctant to raise the price as demand would contract by a greater percentage and revenue would fall therefore keeping the price cheap.

The quality may also be high if the elastic demand is the result of the existence of close substitutes. In this case, a producer may have to provide a good quality product to remain competitive.

47
Q

Define inelastic supply

A

When the quantity supplied changes by a smaller percentage than the change
in price.

47
Q

Define inelastic supply

A

When the quantity supplied changes by a smaller percentage than the change
in price.

48
Q

The three main factors which determine the PES of a product are:

A

i the time taken to produce it
ii the cost of altering its supply and
iii the feasibility of storing it.

49
Q

What can make a product supply more elastic?

A
  • More time

- Advances in technology

49
Q

Changes in PES

A

The supply for most of the products becomes more elastic as the time period increases.
Advances in technology, by reducing the production period and lowering costs of production, make the supply more elastic.

50
Q

Why is elastic supply beneficial to all?

A

Consumers: Supply is responsive to consumer demand

Producers: Higher profits if they are responsive enough

Government: If governments want to encourage the output and consumption of a product they are likely to be more successful giving a subsidy to producers if supply is elastic.

51
Q

Difference between public and private sector

A

The private sector covers business organisations which are owned by shareholders or individuals. These organisations respond to changes in market forces and are profit motivated.
The public sector is controlled by the government. It covers government run services and state-owned enterprises (SOEs), also called nationalised industries.

52
Q

Define state-owned enterprises (SOEs)

A

Organisations owned by the government which sell products

53
Q

Advantages of a market economic system

A
  • Consumers are said to be sovereign
  • Costs and prices may be low- The profit motive and competition promote efficiency
  • Quality may be high
  • There is choice- Consumers can choose which products to buy and which firms to buy from. Firms can also decide what they want to produce and workers can choose who to work for.
  • Resources should change quickly to reflect changes in consumer demand. This is for three reasons.
    1. Market economic system provides information/incentive on which products are increasing in demand and which ones are falling in demand.
    2. It punishes those firms, workers, and owners of capital and land who do not respond to changing demand.
54
Q

Define price mechanism

A

The system by which the market forces of demand and supply determine prices.

55
Q

Define Market failure

A

Market forces resulting in an inefficient allocation of resources.

56
Q

Disadvantages of a market economic system

A
  • Consumers and private sector firms may only take into account the costs and benefits to themselves and not the costs and benefits of their decisions to others.
  • A market may become dominated by one or a few firms- limited or no choice for consumers+ can raise the prices of their products and produce poor quality products
  • Workers lack the right skills or are geographically immobile.
  • Firms will not make products unless they think they can charge for them, e.g. defense- people can act as free riders.
  • Advertising can distort consumer choice
  • Uneven distribution of income which will increase over time.
57
Q

Define free rider

A

Someone who consumes a good or service without paying for it.

58
Q

How is the role of the government reduced in a market economic system?

A

By removing a number of government regulations, selling off SOEs and parts of SOEs (privatisation) and lowering taxation.

59
Q

Define Market failure

A

Market failure occurs when market forces fail to produce the products that consumers demand, in the right quantities and at the lowest possible cost.

68
Q

Define asymetric information

A

When consumers and suppliers do not have equal access to information

69
Q

Define merit goods

A

Products which the government

  • considers consumers do not fully appreciate how beneficial they are
  • and so which will be under-consumed if left to market forces.
  • Such goods generate positive externalities.
70
Q

How can the government increase the demand of merit goods?

A
  • Providing information on the benefits of consumption of the product
  • Making the product compulsory (e.g. seat belts)
  • Provide subsidies that will decrease the price
  • Provide the product for free
71
Q

Define demerit goods

A

Products which the government

  • considers consumers do not fully appreciate how harmful they are
  • and so which will be over-consumed if left to market forces.
  • Such goods generate negative externalities.
72
Q

How can the government decrease the demand of demerit goods?

A
  • Imposing a tax on them
  • Providing information about their harmful effects
  • Ban them

  • Making price-fixing illegal
  • Stop firms from merging
  • Regulation of monopolies
  • Prohibition of limit pricing and predatory pricing
78
Q

Why may private sectors under-invest?

A

They are keen to earn high profits in the short term

79
Q

Define

  • Allocative efficiency
  • Productive efficiency
  • Dynamic efficiency
A

Allocative efficiency: When resources are allocated to produce the right products in the right quantities

Productive efficiency: When products are produced at the lowest possible cost and making full use of resources

Dynamic efficiency: Efficiency occurring over time as a result of innovation and investment

80
Q

Define mixed economic system

A

An economy in which both the public and private sectors play an important role

81
Q

Advantages of government intervention in a mixed economic system?

A
  • Govt will take into account all the costs and benefits that will arise from their decisions (if its not profitable to the private sector but the benefits to society are more than the costs, the state will maintain it)
  • They can encourage the consumption of products by granting subsidies, providing information or passing legislation
  • They can discourage the consumption of products by imposing taxes, providing information or passing legislation
  • They can finance the production of products that cannot be charged for directly
  • They can prevent private sector firms from exploiting consumers by charging high prices
  • They will seek to make maximum use of resources (e.g. labour: rising employment)
  • They will plan ahead to a greater extent and hence devote more resources to capital goods
  • They will help more vulnerable groups ensuring they have access to basic necessities (taxing the rich at a higher rate to even out distribution of income)
82
Q

How may setting a maximum price be effective?

A

It will enable the poor to afford basic necessities as they will be able to purchase the products at a lower price, only if its set below equilibrium price.

This can lead to shortage as at this lower price the quantity demanded exceeds the quantity supplied

83
Q

Define rationing

A

A limit on the amount that can be consumed

84
Q

Define lottery

A

The drawing of tickets to decide who will get the products

85
Q

How may setting a minimum price be effective?

A

To encourage the production of goods. This is effective when it’s set above the equilibrium price however that will lead to a surplus as at that price, the quantity supplied is more than the quantity demanded.

86
Q

How are firms affected by taxes?

A

Governments tax their profits which has an effect on their willingness and ability to invest
Indirect taxes raise a firms cost of production
Income tax reduces consumers disposable income which will affect the demand for the firms products

87
Q

The effect of a subsidy given to producers is influenced by:

A
  1. The size of the subsidy

2. Price elasticity of demand

88
Q

Effect of a governments tax on elastic demand/ inelastic demand?

A

Elastic-
The revenue will fall
Would be easier to discourage consumption of a product

Inelastic-
The revenue will rise

89
Q

What is the competition policy?

A

It seeks to promote competitive pressures and prevent firms from abusing their monopoly power

90
Q

Define limit pricing

A

Setting the price low enough to dicourage the entry of new firms into the market

91
Q

Define predatory pricing

A

A firm charging a price below the cost to drive rival firms out of the market

92
Q

Government measures to address market failure

A
  1. Subsidies and taxes
  2. Competition policies
  3. Environmental policies
  4. Regulation
  5. Nationalisation and privatisation
93
Q

Explain tradable permits

A

This involves a government issuing permits to firms, allowing them to pollute up to a certain limit and to sell part of their allocated limit, if they pollute less.

This will reduce the costs of the cleanest firms, whilst raising the costs of the worst polluting firms. As a result, the cleanest firms should capture a higher market share and consequently, pollution should fall.

94
Q

Advantages and disadvanatges of regulations

A

A:

  1. Backed up by the law
  2. Easily understood

D:

  1. Difficult and expensive to check whether they are being followed
  2. Works only if most people agree with it ( government may become unpopular)
  3. They do not directly compensate those who suffer as a result of market failure
  4. May be too restrictive- reducing market flexibility
95
Q

Define nationalisation

A

Moving the ownership and control of an industry from the private sector to the government

96
Q

Define public corporation

A

A business organisation owned by the government which is designed to act in the public interest

97
Q

Advantages of state owned enterprises

A
  1. Base their decisions on the full costs and benefits involved
  2. Can be used to influence economic activity- boost countrys output
  3. Would not abuse market power
  4. Makes planning and coordination easier since everything is owned by the government
  5. Ensures basic industries charge low prices and produce good quality
98
Q

Disadvantages of state owned enterprises

A
  1. Could be difficult to manage due to the large size
  2. With the guarantee that they can’t go bankrupt and the lack of competition, they may charge high prices or produce low quality
  3. Would need to be subsidised if in a loss- opportunity cost for the subsidy
99
Q

Advantages of privatisation

A
  1. Efficient with response to market changes due to the threat of bankruptcy and reward of profits
  2. More choice
  3. Right products at good quality and low prices
  4. Reduced government intervention will lead to less administration costs
  5. Less risk of under-investment
100
Q

Disadvantages of privatisation

A
  1. Monopolies- no guarantee of competition (lead them to be inefficient charging high prices for low quality products)
  2. May not take into account all costs and benefits to society
101
Q

Disadvantages of government intervention

A
  1. Corruption- if their interest lies in getting votes
  2. Reducing incentives
    If unemployment benefits are high, people may be discouraged to work
    If there are high taxes on firms profts, entrepreneurs willingness and ability to invest is reduced
