Communist countries have command economies but they are much rarer since the collapse of communism in the late 20th century.

Question 9

When does market failure happen?

Answer 9

Market failure happens when free markets results in undesirable outcomes

Question 10

• They might change the law or offer tax breaks or create some other kind of incentive to try and influence people’s behaviour
• Governments can also intervene in the economy by buying or providing goods or services

Question 11

What is it called when both the government and markets play a part in allocating resources?

Answer 12

3

Question 13

What are the three sectors in a mixed economy?

Answer 13

Question 19

What time period did Adam Smith live in?

Answer 19

The 18th century

Question 20

What time period did Karl Marx live in?

Answer 20

The 19th century

Question 21

What time period did Friedrich Hayek live in?

Answer 21

The 20th century

Question 22

What have Adam Smith’s ideas shaped?

Answer 22

Traditional economic theory

Question 23

What was Adam Smith a big believer in and what did he say about it?

Answer 23

Adam Smith was a big believer in the free market and described how its invisible hand would allocate resources in society’s best interests

Question 24

How did Adam Smith say that the invisible hand of the market came about?

Answer 24

He said that it came about because consumers and producers are motivated by self interest - consumers are motivated to maximise their own benefits and producers are motivated to maximise profit. In a free market consumers demand and producers supply will lead to price levels being set at a point which benefits them both

Question 25

What did Adam Smith say there needed to be for the free market to work properly?

Answer 25

There couldn’t be any monopolies and there would have to be low barriers to entry to maximise competition

Question 26

As well as the free market what else did Adam Smith also write about?

Answer 26

Specialisation and the division of labour

Question 27

What was Karl Marx critical of and why?

Answer 27

Karl Marx was critical of the free market and argued that it created a situation where a small ruling class of producers known as the bourgeoisie dominated and exploited the larger working class of wage earners called the proletariat

Question 28

What did Marx argue about bourgeois producers?

Answer 28

Marx argued that the profit-maximising bourgeois producers would exploit workers for example by paying them low wages and giving them few rights until the proletariat eventually rose up in a revolution and took over. This would then lead to the workers controlling production and everyone having a share of ownership of resources

Question 29

What did Marx’s ideas lead to the rise of?

Answer 29

Marx’s ideas led to the rise of communism in the 20th century but his ideas contained little about how command economies would work. Many communist countries collapsed in the late 20th century which led to the discrediting of communism and command economies but Marx’s ideas are becoming more popular now

Question 30

What was Friedrich Hayek a supporter and a critic of?

Answer 30

Friedrich Hayek was a keen supporter of the free market system and a critic of command economies. He argued that governments shouldn’t intervene to allocate resources because governments lack the information required to allocate them in the way that is most beneficial to society

Question 31

What did Hayek believe about individual consumers and producers?

Answer 31

Hayek believed that individual consumers and producers have the best knowledge of what they want or need and so the allocation of resources should be left to them and the price mechanism

Question 32

What did Hayek see the price mechanism as a way of?

Answer 32

Hayek saw the price mechanism as a way for producers and consumers to communicate, this is the idea of price acting as a signalling device between consumers and producers. The price level set by the forces of supply and demand would show what both consumers and producers want and will naturally allocate resources in a much more efficient way than governments can

Question 33

When is a market in equlibrium?

Answer 33

When supply equals demand

Question 34

At equilibrium what is the relationship between price and output?

Answer 34

At equilibrium, price and output are stable. There is a balance in the market and supply is equal to demand. All products that are presented for sale are sold and the market is cleared

Question 35

In a free market what determines the equilibrium price and quantity?

Answer 35

Supply and demand

Question 36

What is the free interaction of supply and demand determining the equilibrium price and quantity in a free market called?

Answer 36

Market forces

Question 37

Where can the equilibrium point on a supply and demand diagram be found?

Answer 37

It can be found at the point where the supply curve and demand curve meet

Question 38

Define disequlibrium

Answer 38

When supply and demand aren’t equal the market is in disequlibrium

Question 39

If there is excess supply or demand what will the market be in?

Answer 39

Disequilibrium

Question 40

What do market forces do?

Answer 40

Market forces act to remove excess supply or demand

Question 41

When does excess supply occur?

Answer 41

Excess supply is when the quantity supplied to a market is greater than the quantity demanded

Question 42

When does excess demand occur?

Answer 42

Excess demand is when the demand for a good/service is greater than its supply

Question 43

What effect will shifts in demand or supply curves have on market equilibrium?

Answer 43

It will change the market equilbrium

Question 44

Will price inelastic supply or demand have a greater impact on price or quantity of the shifts of demand or supply curves?

Answer 44

Price

Question 45

Will price elastic supply or demand have a greater impact on price or quantity of the shifts of demand or supply curves?

Answer 45

Quantity

Question 46

What does price elasticity of supply and price elasticity of demand influence the size of change of?

Answer 46

Changes in the equilibrium price and quantity caused by supply and demand curve shifts

Question 47

Under what conditions do competitive markets exist?

Answer 47

• When there are a large number of buyers (consumers) and sellers (producers)
• When no single consumer or producer can influence the allocation of resources by the market or the price that goods and services can be bought at

Question 48

What is assumed about consumers and producers in a competitive market?

Answer 48

That they act rationally

Question 49

How do consumers and producers act rationally in a competitive market?

Answer 49

• Consumers aim to maximise their welfare by buying goods/services to maintain or improve their quality of life
• Producers compete to provide consumers with what they want at the lowest possible price so they can maximise their profit by selling to the most customers

Question 50

What is the main way of allocating resources in a market economy?

Answer 50

Price

Question 51

Define price

Answer 51

The value at which a good or service is exchanged is known as its price

Question 52

Define the price mechanism

Answer 52

Changes in the demand or supply of a good or service leads to changes in its price and to the quantity bought/sold. This is known as the price mechanism

Question 53

Explain how the price mechanism allocates goods and services

Answer 53

The price mechanism allocates goods/services in an impersonal way known as the invisible hand of the market, as prices will change until equilibrium is achieved and supply equals demand. Its free from people’s biases and opinions.
The price mechanism also coordinates the decisions of buyers and sellers. For example how expensive something is will influence whether someone buys it and how much of it producers supply

Question 54

What are the three functions of the price mechanism?

Answer 54

• An incentive device
• A signalling device
• A rationing device

Question 55

Explain how the price mechanism can act as an incentive device

Answer 55

The price mechanism acts as an incentive device - higher prices allow firms to produce more goods and services and encourages increased production and sales by providing higher profits

Question 56

Explain how the price mechanism can act as a signalling device

Answer 56

The price mechanism acts as a signalling device as changes in price shows changes in supply and/or demand and act as a signal to producers and consumers. For example a price increase is a signal to producers that demand is high so this will encourage them to increase production

Question 57

Explain how the price mechanism can act as a rationing device

Answer 57

The price mechanism acts as a rationing device as if there is high demand for a good or service and its supply is limited then the prices will be high. Supply of the good will be restricted to those that can afford to pay a high price.
The opposite applies for goods that are low in demand but in high supply, they will have a low price and many will be sold.

Question 58

Apart from its 3 main functions how else is the price mechanism used?

Answer 58

The price mechanism is also used to allocate the resources used to produce goods and services. For example if demand for curtains increases the market will allocate through the price mechanism more curtains to consumers, more labour for making curtains and more commodities to curtain manufacturers.

Question 59

What are the advantages of the price mechansim?

Answer 59

• Resources will be allocated efficiently to satisfy consumer’s needs and wants
• The price mechanism can operate without the cost of employing people to regulate it
• Consumers decide what is and isn’t produced by producers
• Prices are kept to their minimum as resources are used as efficiently as possible

Question 60

What are the disadvantages of the price mechanism?

Answer 60

• Inequality in wealth and income is likely
• People with limited skills or ability to work will suffer unemployment or receive very low wages
• Public goods won’t be produced

Question 61

What effect can introducing the price mechanism into an area of human activity have?

Answer 61

Introducing the price mechanism into an area of human activity can have unintended consequences

Question 62

What are the advantages of a free market economy?

Answer 62

1- There will be increased efficiency as only products of the best value will be in demand giving firms an incentive to make goods and services as efficiently as possible
2- In a free market economy rewards for good ideas can make entrepreneurs lots of money encouraging innovation and risk taking
3- The incentive for innovation can lead to increased choice for consumers and in a free market consumers are not restricted to buying what the government recommends

Question 63

What are the disadvantages of a free market economy?

Answer 63

1- Free market economies can lead to huge differences in income which can lead to inequality. Also people unable to work would receive no income
2- Non-profitable goods would not be made such as medicines to treat rare conditions as they would not sell enough to make profits for firms
3- Monopolies are likely to form as successful businesses may become the only supplier of a good and this market dominance could be abused.

Question 64

What are the advantages of a command economy?

Answer 64

1- Governments can maximise welfare by preventing inequalities and redistributing incomes fairly. They can also ensure the production of beneficial goods to society
2- The government can try to keep unemployment low by providing everyone with a job and salary
3- The market dominance of monopolies can be prevented by the government

Question 65

What are the disadvantages of a command economy?

Answer 65

1- A lack of information could mean that the government make poor and slow decisions about what needs to be produced
2- Consumers may have limited choice in what they can consume as firms will only make what they are told to make
3- Government-owned firms have no incentive to increase efficiency or take risks or innovate as they have no profit motive
