51
Q

What does a typical PPF show

A

As more of one good is produced, an increasing amount of the other is forgone so the opportunity cost rises

52
Q

Why does the OC rise

A

Not all resources are as efficient as other resources in the production of both goods, so diminishing returns set in

53
Q

What is the law of diminishing returns

A

A point at which the level of profits or benefits gained is less than the amount of money or energy invested.

54
Q

Example of PPF in action

A
  • We can assume that farmland can be used for growing wheat of livestock production
  • East Anglia has highly fertile and light soils with suitable rainfall for growing wheat
  • Their output per acre is very high
  • As we move towards the southwest, soil becomes too heavy
  • Rainfall becomes too high for growing wheat
55
Q

Why would livestock farming be more productive per acre

A
  • If farmland in the southwest were converted to wheat production, yields would be very low
  • Yields would only be achieved at a cost of forgoing livestock output
56
Q

Diagram of increase in the PPF

A

(Real card 2)

57
Q

What does the outward shift in the PPF show

A

That a country’s production potential may increase over time and this represents economic growth

58
Q

What may be the causes of economic growth shown by the PPF

A
  • An increase in the quantity or quality of resources
  • The expansion of further and higher education
  • Expansion in government training schemes
  • An increase in investment
  • The development of new technology
59
Q

What does the inward shift of the PPF towards the origin indicate

A

A decrease in the potential output of an economy which represents a reduction in economic growth

60
Q

What may a decrease in potential output be cased by

A

•A natural disaster where resources are destroyed

61
Q

Define specialisation

A
  • When an individual, firm, region or country

* Concentrates on the production of a limited range of goods and services

62
Q

Advantages of specialisation

PUGS

A
  • Productivity rises
  • UK specialises in production of medicinal drugs and tourism
  • Goods and services can be traded for other goods and services by other countries
  • So higher levels of global output and higher living standards
63
Q

Disadvantages of specialisation

MALT

A
  • Many developing countries face an unfavourable rate of exchange
  • A country that specialises in production of export of minerals may face problems of resource depletion
  • Large increase in structural unemployment when demand for a good/service falls
  • This means they have to sell commodities at a low price compared to the goods they purchase overseas
64
Q

Define division of labour

A

The specialisation of workers on specific tasks in the production process

65
Q

Process of division of labour

A
  • Individuals focus on the production of a particular good/service
  • Production is broken down into a series of tasks
  • Each task is conducted by different workers
66
Q

Adam Smith division of labour example

A
  • If pin production were broken down into 18 different specialist tasks
  • Where each task was carried out by a different worker
  • The output of pins would increase by 2000%
  • In comparison to a situation where each worker completed all the tasks involved
67
Q

Main advantages of division of labour

COLE

A
  • Cost per unit of output reduced
  • Output per worker per hour rises-higher productivity:
  • Living standards rises
  • Efficiency of resources increases
68
Q

What are the reasons for increased productivity

A
  • Workers becoming highly skilled in a task due to repetition
  • No time is wasted in moving from one job to another
  • Capital equipment used continuously in production
  • Less time required to train workers for specific tasks
  • More choice of jobs for workers
  • Workers can specialise in the tasks they are most suited to
69
Q

Disadvantages of division of labour

A

•Structural unemployment can be caused
(self-service scanning machines instead of cashiers)
•High turnover of staff leads to increased recruitment costs
•Interdependence in production-if one group of workers were on strike, production could be halted across the whole industry
•Repetition creates monotony and boredom
•Easier to replace skilled workers with machines if production broken down into different tasks

70
Q

Define money

A

Anything that is generally acceptable in the payment of a good or service, or of a debt

71
Q

What forms do money come in

A

Largely cash and bank deposits

72
Q

What do advances in technology mean for money

A

We are moving towards a cashless society where most payments occur through debiting and crediting bank accounts

73
Q

What has the development of money enabled

A

It has enabled specialisation and trade to grow, leading to sophisticated economies of today

74
Q

Why is it crucial that people have confidence in the money used

A

Otherwise it will lose its general acceptability for making transactions, and so will cease to be money

75
Q

Example of why confidence in money is important

A

In Zimbabwe the government printed off too much money leading to hyperinflation and a worthless currency

76
Q

What are the four functions of money

A
  • Medium of exchange
  • Measure of value
  • Store of value
  • Method of deferred payment
77
Q

What does money as a medium of exchange enable

A
  • Enables buying and selling of products which makes exchange easier
  • Money eliminates the need for barter
78
Q

What does money as a measure of value enable

A
  • Enables a value to be placed on products
  • So they can be bought and sold with ease
  • Money creates a unit of measure that enables comparisions between relative values of products
79
Q

What does money as a store of value enable

A
  • It is a convenient way of storing wealth so that it can be spent at a later date
  • Money will tend to hold its value in the short term if inflation remains low
80
Q

What does money as a method of deferred payment enable

A
  • It enables borrowing and lending

* This means someone can borrow money to buy a product rather than waiting until enough funds have been saving

81
Q

What is the rate of interest

A

The price set for borrowing and lending

82
Q

Why does an economy organise its resources in different ways

A

To produce goods and services

83

  • Best example of a developed country with a small government sector is Japan
96
Q

Advantages of a free market economy

1.Economic efficiency and lower prices:

A

1.Economic efficiency and lower prices:
•Competition means firms try keep production costs low
•In order to sell goods and services at competitive prices(productive efficiency)
•Competition means firms try to produce goods and services that consumers demand(allocative efficiency)
•This means the price mechanism will equate consumer demand with producer supply

97
Q

Advantages of a free market economy

2.Quality of products

A

2.Quality of products
•Competition means firms continuously try to improve quality of their products
•This allows firms to gain an advantage over rivals
•There is considerable consumer power and authority in the market

98
Q

Advantages of a free market economy

3.Greater choice

A

3.Greater choice
•Consumers can often choose to buy from a wide selection of goods and services
•Workers often have a wide choice of employment opportunities

99
Q

Advantages of a free market economy

4.Financial incentives

A

4.Financial incentives

100
Q

Disadvantages of a free market economy

2.Unequal distribution of income

A

2.Unequal distribution of income

•For example, the price mechanism ignores the external costs of pollution and external benefits of education

102
Q

Disadvantages of a free market economy

4.Persistent information gaps

A

4.Persistent information gaps
•People may consume excessive amounts of demerit goods whilst being unaware of their dangers
•E.g drugs, tobacco and alcohol
•There is a lack of regulations and taxation to protect consumers

103
Q

Disadvantages of a free market economy

5.Insufficient quantity of goods

A

5.Insufficient quantity of goods
•An insufficient quantity of public goods and merit goods is provided in a market economy
•Public goods include defence and street lighting
•Merit goods include healthcare and education
•These goods may be underprovided by the free market

104
Q

Disadvantages of a free market economy

6.Erratic swings in the business cycle

A

6.Erratic swings in the business cycle
•Erratic swings in the trade cycle may cause high inflation during an economic boom
•They may also cause high unemployment during an economic slump

105
Q

Define command economy

A
  • Where there is public ownership of resources and these are allocated by the government
  • Therefore there is no role for the price mechanism
106
Q

Who makes the decisions on what, how and for whom to produce

A

The government

107
Q

What did Karl Marx believe

A

Production should be directed on the basis of human need rather than profit

108
Q

When can command economies work effectively

A

During times of national crisis:

•E.g the UK was run like a command economy during WW2

109
Q

Evaluation of effectiveness of command economies

A
  • However personal freedom and living standards can be jeopardised
  • For example North Korea
110
Q

Advantage of a command economy:

1.maximised output

A
  • Cooperation between firms leads to high levels of output

* Maximisation of output replaces the maximisation of profits as the key aim of firms in general

111
Q

Advantage of a command economy:

2.reduction in inequality

A

•There is a reduction in inequality compared to free market economies as the government controls wages of all workers

112
Q

Advantage of a command economy:

3.Limited external costs

A
  • Governments may limit external costs from production and consumption
  • E.g they can limit pollution emissions from firms and place taxes on demerit goods such as alcohol
113
Q

Advantage of a command economy:

4.Funding of public goods + increased external benefits

A
  • The government can fund the provision of public goods such as defence and law and order
  • Governments can also increase the provision of goods which yield high external benefits to society
  • E.g education and healthcare
114
Q

Advantage of a command economy:

5.Less unemployment and inflation

A
  • The government has more control of the economy

* Therefore there are smaller swings in the business cycle, leading to less unemployment and inflation

115
Q

Disadvantage of a command economy:

1.Inefficient allocation of resources

A
  • Price mechanism unable to operate
  • So markets may suffer from excess demand and excess supply/shortages and surpluses
  • This leads to an inefficient allocation of resources
116
Q

Disadvantage of a command economy:

2.Low productivity

A
  • Lack of competition between firms
  • This leads to inefficiency
  • Therefore productivity is low
117
Q

Disadvantage of a command economy:

3.Poor quality products

A
  • Lack of competition between firms
  • May be more emphasis on maximising output rather than profit
  • This leads to poor-quality products
118
Q

Disadvantage of a command economy:

4.Narrow choice of goods, services and labour

A
  • Less choice of goods and services for consumers to choose

* Labour may be directed into specific jobs with no choice depending on their location

119
Q

Disadvantage of a command economy:

5.Lack of financial incentives

A
  • Main focus for managers is to maximise output
  • So managers have no profit incentive to take risks
  • Wages are fixed by government so labour has little incentive to work hard
120
Q

Disadvantage of a command economy:

6.Under-performance of command economies

A
  • Economic growth and living standards tend to grow at a slower rate than in market-based economies
  • This was a major cause of the collapse of the Soviet Union during the early 1990s
  • This indicates under-performance of command economies
121
Q

Who makes the decisions on what, how and for who to produce for a mixed economy

A

The private sector and the government

122
Q

Define mixed economy

A

Where some resources are owned and allocated by the private sector and some by the public sector

123
Q

What is the reasoning for a mixed economy

A

To gain the advantages of the market economy whilst avoiding its disadvantages through government intervention

124
Q

Who is associated with mixed economies

A

John Maynard Keynes

125
Q

Why does government intervention occur

A

To correct market failure and help markets work more effectively:
•E.g the under-provision of merit goods such as education and healthcare
•E.g the non-provision of public goods such as defence
