Q

What is the classical view of the LRAS

A

They think the LRAS is a vertical line
They think that changes to AD cause the prices of factors to change which causes the SRAS to shift to the previous GDP value

Q

What is the policy implications of the classical view of LRAS

A

Governments are powerless to influence GDP to changes to AD
Boosting AD only boost GDP in the short run
In the long run, boosting AD causes inflation
Governments can cause economic growth in the long run by shifting the LRAS

Q

How does the macro economy self correct

A

When there is insufficient demand in the economy, surpluses of goods cause the prices to fall until consumers are willing to buy them. This causes AD to increase

When there is excessive demand, shortages of goods drive prices up until consumers start to consume less causing AD to decrease

A

It forms when asset prices are driven beyond the point where they reflect the underlying value of the asset

45
Q

What are examples of asset market crashes

A

Bitcoin crash in 2020-21
The US houding bubble that caused the global recession of 2008-09

46
Q

What explains the volatility of asset markets

A

Herd behaviour
information uncertainty

47
Q

What are the stages of asset bubbles and crashes

A

The upswing - increase in value
The pop - the fall in value
The bounce - the recovery of price

48
Q

What are the implication of asset markets in the real economy

A

Changes in asset prices effect the wealth of holders
The more or less wealthier people, the more or less confident they are
Wealth effect

49
Q

What do credit markets allow to happen

A

It allows people to spend their future income in the present and then have to spend less in the future when paying it off

50
Q

What are the effects of credit markets on the trade cycle

A

During periods of borrowing AD will be higher then it could be if everyone spend what they earned
When debts come to be repaid, AD falls as people spend less

51
Q

What is the classical economists view of stabilising the macro-economy

A

Automatic self correction
Too much information failure to make effective changes

52
Q

How does the economy self correct

A

In a economic downturn AD falls so firms will cut prices because of the lower demand
This causes lower demand for labour , which causes workers to accept lower wages
Falling prices causes consumer to start spending and firms to start hiring again
Business confidence returns and investment increases
AD rises

53
Q

What is the classical view of interference by governments

A

It makes the economy worse and de-stabilises the recovery mechanism

54
Q

Why does interference make the economy worse at recovering

A

Uncertainties about the output gap
Uncertainties about the size of the multiplier
Uncertainties about the time lags involved when implementing policies
Crowding out effects of government activity

55
Q

What is the problem with output gaps

A

They are hard to accurately measure
Hard to measure actual output because of errors and black markets
Hard to measure potential output because of mass immigration, rapid technological change and changing productivity

56
Q

What is the problem with the multiplier

A

Hard to measure as it isn’t constant
Need to predict future leakage rates

57
Q

What is the problem with time lags

A

It means that policies don’t take effect instantly

58
Q

What are examples of time lags

A

Interest rate cut by Bank of England indicates for commercial bank to cut rates
Banks need to inform customers on variable loans
Customers take time to react and adjust spending
Firms will take time to feel effect of sales
Firms take time to adjust output
Government takes time to measure changes to GDP

59
Q

How long are time lags normally

A

18 months to 2 years

60
Q

What the problem with crowding out

A

As governments try to spend more they replace who is doing the spending by crowding out the private sector through borrowing or higher taxation

61
Q

What is the quantity Theory of Money

A

Theory of why money loses value
Money is devalued when its supply rises too quickly and this loss of value is shown as inflation

62
Q

What is the relationship between quantity of money in circulation and the average price level

A

Direct relationship

63
Q

Who developed the Quantity Theory

A

Irving Fisher

64
Q

What is the Fisher identity or equation of exchange

A

Identity made from the Quantity Theory of Money
MV = PQ
M= Money supply
V = Velocity of circulation of money
P = Price Level
Q = Real Quantity of output

65
Q

What is the velocity of circulation of money

A

The average number of times a unit of currency changes hands in a year

66
Q

What 2 assumptions turn the Fisher identity into the monetarist theory

A

The velocity of circulation of money is stable
The volume of output produced in an economy is stable

67
Q

What does the Monetarist theory suggest then

A

That the money supply is directly linked to the general price level
An increase in output in the short run will not cause a change in the price level as long as the money supply changes by the same amount

68
Q

What were the policy implications of the monetarist theory

A

Governments who wanted to control the price level would restrict the change in money supply to match the short run growth of output

69
Q

What are the challenges to the monetarist theory

A
  1. An increase in the velocity of circulation of money caused by inflationary expectations can cause inflation
  2. A fall in output but with constant money stock causes inflation e.g. wartime
  3. An increase in money supply could lead to an increase in output when there is a large output gap (Horizontal LRAS curve)
  4. A rise in the money supply could be neutralised by a fall in velocity of circulation e.g. lockdown
  5. Keynes argued that a price level rise causes the money supply to rise as the cost of living rises
70
Q

What are the economic costs of inflation

A

1.Effect on UK competitiveness
2.Problem of the wage-price spiral
3.Redistribution of income from savers to borrowers
4.Consumers and businesses on fixed incomes lose out
5.Usually leads to higher nominal interest rates
6.Disrupt business planning
7.Distorts the operation of the price mechanism
8.Shoe leather cost/search costs
9.Menu costs

71
Q

What is the effect of inflation on UK competitivness

A

Inflation causes a loss of price competitiveness in international markets
AD falls from falling exports

72
Q

What is the evaluation of the effect on UK competitivness

A

Assumes a given exchange rate - depreciated exchange rate
Depends on relative inflation rate
Depends on the selling prices of UK goods
Source of inflation - Excess demand for exports won’t effect competitiveness
It will hurt open economies more

73
Q

What is the wage price spiral

A

Price level rise can lead to higher wage demands
Higher wages causes unit labour costs to rise if above the increase in productivity
This causes firms to raise prices to maintain profit levels
Causing inflation

74
Q

What is the evaluation of the wage price spiral

A

The second rise in inflation depends on how monopsonistic and monopolistic the labour market is
The more it is, the more likely wages will rise

75
Q

What is the redistribution of income from savers to borrowers

A

Inflation causes a reduction in the real value of savings when real interest rates are negative
The real value of debt is diminished

76
Q

How will consumers and businesses on fixed income lose out

A

Fixed pensions have their real value diminished
The state pension is normally adjusted for inflation each year

77
Q

What is the evaluation of consumers and businesses on fixed incomes losing out

A

The CPI only takes into account the average spending patterns of consumers
Consumers with abnormal spending patterns like pensioners will have a different inflation rate
This means that there incomes are not adjusted for inflation

78
Q

How can inflation disrupt business planning

A

It causes uncertainty about the future which makes planning hard
This may have a negative impact on the level of planned investment

79
Q

How can inflation distort the operation of the price mechanism

A

Results in inefficient allocation of resources
When inflation is volatile, consumers and firms won’t have enough information to make good decisions

80
Q

What is the evaluation of the disruption of business planning

A

The volatility of inflation is what makes planning hard as firms don’t know their future costs and revenue
Unanticipated inflation is worse as it can’t be planned for

81
Q

What are shoe leather costs/ search costs

A

Inflation makes it harder for consumers to find the best deals and see relative prices
This extra brings opportunity costs

82
Q

What is the evaluation of shoe leather costs

A

This is a very small impact of inflation
Price comparison websites reduces the search cost

83
Q

What are menu costs

A

They are the extra costs to firms of changing price information
This is important to firms with bulky catalogues

84
Q

When is inflation the worst

A

High, volatile and unanticipated
Open economies with large amounts of people on fixed incomes
Wage price spiral

85
Q

What are the economic benefits of inflation

A

Encourage investment
Falling debt values
Rising Asset Values - Wealth Effect
Lack of inflation leads to low real output and employment
Money illusion

86
Q

How does Inflation encourage investment

A

Profits may be eroded sitting in banks at negative real interest rates
Firms decide to invest the money instead

87
Q

What is the money illusion

A

Inflation allows the government to increase nominal spending and reduce real spending
Allows the government to operate negative interest rates

88
Q

What is deflation

A

A sustained fall in the general price over time
Negative Inflation

89
Q

What are the 2 types of deflation

A

Benign
Malign

90
Q

What is benign deflation

A

Supply side improvements - increase in supply
Causes increased output, employment and real living standards, rising real incomes
Caused by productivity, commodity prices, tech
Associated with long run supply side growth

91
Q

What is malign deflation

A

Fall in the level of aggregate demand
Causes falls in output, employment and living standards
Hard to get rid of if deflationary expectations set in causing downward multiplier impact

92
Q

What is deflationary expectations

A

Consumers and firms expect deflation so postpone their consumption and investment
Increasing savings ratio and reduces velocity of circulation of money
Less C+I reducing AD

93
Q

What is the disadvantage of both deflations

A

It raises the real value of debt
This makes it more expensive for borrowers and causes increased opportunity costs in other spending areas

94
Q

What is another disadvantage of both deflations

A

It makes monetary policy less effective
Deflation makes it impossible to achieve negative real interest rates
This makes it hard to stimulate the economy

95
Q

What is the equation for real rate of interest

A

Nominal roi - inflation rate

96
Q

What country has experienced malign deflation

A

Japan

97
Q

What were the Prime Ministers 3 main economic policies to remove deflation

A

Negative central bank interest rate and QE
Expansionary Fiscal Policy
Supply side structural reforms making markets more efficient

98
Q

What does Negative central bank interest rate do

A

Commercial banks are charged to hold money with the Bank of Japan
This incentives them to lend the money out

99
Q

What is quantitative easing QE

A

The central bank pumping liquidity into the economy by buying bonds from existing holders

100
Q

What is the short run Phillips curve

A

A inverse non-linear relationship between inflation rate and unemployment rate
Developed by AW Philips
Inflation y-axis
unemployment x-axis

101
Q

What explains the short run Phillips curve relationship

A

Low unemployment means that there is a high average income so high consumption
It also means higher wages for workers as its harder to replace them - higher costs

High unemployment causes low average wages and low costs for firms

102
Q

What did the short run Phillips curve mean for governments

A

It offered governments a trade off between inflation and unemployment
The non-linear relationship causes a greater opportunity cost as you try to reduce 1 variable closer to zero

103
Q

What is the natural rate of unemployment

A

Unemployment when all labour markets were in equilibrium with all willing and able people in work
The unemployment was caused by frictional, structural or voluntary unemployment

104
Q

What is the long run phillips curve

A

A vertical line positioned at the economies natural rate of unemployment
No trade-off between inflation and unemployment

105
Q

How does the long run Phillips curve work

A

If a short run demand stimulus is added, inflation rises and unemployment falls
The position is held in the long run until the money illusion stops i.e. higher nominal wages but same real wages
Workers leave the market and unemployment falls back to original rate at LRPC but with higher inflation rate

106
Q

What are the policy implications of the Long Run Phillips Curve

A

The natural rate of unemployment is immune to demand side policies
The natural rate of unemployment can only be affected by supply side policies
Successive attempts to boost the short run position will shorten its time in the long run

107
Q

Whats the point of inflation targeting

A

It shows a commitment to keeping inflation under control
Achieving the target will reduce inflationary expectations

108
Q

Does it matter if the inflation target is missed

A

Yes and NO
It anchor’s inflationary expectations but won’t be credible if broken lots
Though it wasn’t designed to be always 2%, shocks can disrupt the target

109
Q

Why isn’t the inflation target 0%

A

2% isn’t inflationary if goods are improving 2% each year so there is a quality adjusted target rate of 0%
2% allows negative real interest rates and money illusion
Too high of an opportunity cost
Could easily fall into deflation which is hard to get rid of
