26
Q

Factors that shift short run AS?

A
  • Changes in the cost of raw materials (In the UK most materials are imported, if global competition increases, UK costs fall. cost of these imports depends on demand pressures from other parts of the world)
  • Changes in exchange rates (Strong Pound imports Cheap)
  • Changes in Tax Rates (If there is an increase in taxes costs for all UK firms increase, firms may pass these cost increases into the consumer, increase in taxes decreases the AS curve, push it upwards)
27
Q

What is the Classical view on long run Aggregate Supply?

A

It is a vertical line (economy is operating at full capacity and there is no unemployed resources)

28
Q

What is the Keynesian view on the AS curve?

A
  • Equilibrium can be achieved even below full employment

- According to this the AS curve has a backward bending L shape

29
Q

What are the three distinct section of the backward bending Aggregate Supply Curve?

A
  • Spare Capacity
  • Bottlenecks
  • Full Capacity
30
Q

Why can an economy increase output without any cost pressures, when at the point of spare capacity on the backward bending AS curve?

A

Because the are unused resources such as factories not working at full capacity or unemployed labour

31
Q

What would happen to AD when there is Spare Capacity?

A
  • Aggregate demand my shift to the right

– through fiscal policy (real output will increase without causing an increase in the price level)

32
Q

What happens at the Bottleneck section of the Aggregate Supply curve?

A
  • Constrictions in the supply chain cause cost and wage pressures to build up.
  • usually about labour, which when in short supply causes wages to increase.
33
Q

What causes prices to rise at the bottleneck section of he backward bending supply curve?

A

Labour (wages)

34
Q

On the backward bending AS curve, at the bottleneck section what causes the price to increase (Inflation)?

A
  • in order to attract more workers firms have to increase wage rates to draw more workers in.
  • which will have an effect on the costs of production
  • Cost Are then reflected onto the consumer
35
Q

When at full capacity, are all viable workers in work?

A

Yes

36
Q

When at full capacity all potential workers are in work so how do firms get more workers?

A
  • Firms have to entice workers away from other jobs

- They do this by offering higher wages

37
Q

When AD increases, when on the full capacity part of the backward bending supply curve, what is the long term affect?

A
  • Increased Inflation

- No increase in output

38
Q

According to the Classical economists, can the economy be in equilibrium whilst there is unemployment?

A

No

39
Q

What is the Vertical Axis on and AD/AS?

A

Price level

40
Q

What are the factors in the Labour Market that shift AS to the right?

A
  • Changes in the Relative Productivity
  • Changes in Education and Skills
  • Demographic changes and Migration
  • Increased in Health Spending
41
Q

How does Changes in Relative Productivity cause the AS curve to shift right? (Labour Market)

A
  • Productivity is OUTPUT per unit INPUT, if it increases with a country’s main trading partners, the gap is said to be closing
42
Q

How does Changes in Education and Skills cause the AS curve to shift right? (Labour Market)0

A
  • Increased Spending on education and training should mean that a country’s workforce can produce more output per worker
  • EDUCATION INCREASES THE VALUE OF POTENTIAL OUTPUT
43
Q

How does Demographic changes and migration cause the AS curve to shift right? (Labour Market)

A
  • Decreasing birth rate and increasing life expectancy will cause the labour supply to worsen
  • Changes in the supply of labour shift the AS curve
44
Q

How does Increases in Health Spending cause the AS curve to shift right? (Labour Market)

A
  • An increase in resources in the health sector should mean that workers have fewer days off sick and are active for longer.
  • Can work beyond retirement ages
45
Q

What is meant by the term Supply Side Policies?

A

are government attempts to increase productivity and shift aggregate supply (AS) to the right.

46
Q

What are Free-Market Supply-Side Policies?

A

involve policies to increase competitiveness and competition

47
Q

What are Interventionist Supply-Side Policies?

A

involve government intervention to overcome market failure.

48
Q

In theory what should Supply Side Policies do?

A

should increase productivity and shift long-run aggregate supply (LRAS) to the right.

49
Q

What are the Consequences of Supply-Side Policies?

A
  • Lower Inflation
  • Lower Unemployment
  • Improved Economic Growth
  • Improved Trade and Balance of Payments
50
Q

By implementing Supply-Side Policies how can Lower Inflation be achieved?

A
  • Shifting AS to the right will cause a lower price level
  • This is because the economy is more efficient
  • Supply-Side Policies help reduce cost push inflation
51
Q

By implementing Supply-Side Policies how can Lower Unemployment be achieved?

A
  • Supply-side policies can contribute to reducing structural, frictional and real wage unemployment.
  • Therefore help reduce the natural rate of unemployment.
52
Q

By implementing Supply-Side Policies how can Improved Economic Growth be achieved?

A
  • Supply-side policies will increase the sustainable rate of economic growth by increasing LRAS
  • This enables a higher rate of economic growth without causing inflation.
53
Q

By implementing Supply-Side Policies how can Improved trade and Balance of Payments be achieved?

A

By making firms more productive and competitive, they will be able to export more

54
Q

3 examples of Free Market orientated Supply-Side Policies.

A
  • Privatisation - sell state owned assets to private sector, improve profit incentives.
  • Deregulation - Allow new forms to enter a market, open monopolies to competition
  • Income Tax Cuts - greater incentive to work longer hours
55
Q

2 examples of Interventionist Supply-Side Policies.

A

– Public sector investment - In infrastructure, improve transport and reduce costs
- Education - increase funding to schools and universities, improve labour productivity

56
Q

Limitations of using Supply Side Policies?

A
  • Productivity growth depends largely on private enterprise and trends in technological innovation.
  • In a recession, supply-side policies cannot tackle the fundamental problem which is lack of aggregate demand.
  • Time. All supply-side policies take a long time to have an effect. Some policies, such as education spending may not influence the economy for 20-30 years.
57
Q

What are the factors in the product market that shift aggregate supply to the right?

A

– Technological advances
– changes in government regulation
– competition policy and reduction in barriers to international trade

58
Q

How does Technological Advances cause the AS curve to shift right? (Production market)

A

– Innovation and investment in new ideas tend to reduce costs for all firms

59
Q

How does Changes in Government Regulation cause the AS curve to shift right? (Production Market)

A

– Regulations in the UK economy that have been imposed to try to maintain a disciplined economy
– These regulations have been increasingly deregulated
– reduces costs faced by firms

60
Q

How does Competition Policy and Reduction in the Barriers to International Trade cause the AS curve to shift right?

A

– As a country opens up to more trade, competition drives down prices and inefficient domestic firms give way to overseas the firms with a competitive advantage.
– therefore, as globalisation develops, aggregate supply increases.

61
Q

When I can get demand me to aggregate supply what does this create?

A

Equilibrium real output and price level

62
Q

What will the change in the components of the aggregate demand equation, C plus I plus G plus (X minus M) lead to?

A

– Shift in the aggregate demand curve

– with multiplier effects

63
Q

If A.D. increases what is likely to happen to the price level and output?

A

Both will rise(Depending on the price elasticity of the aggregate supply curve)
