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

What is the Keynesian view of LRAS

A

He belives that factor markets are slow to adjust to changes in market forces
This causes a reverse L looking LRAS curve

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

Q

How useful are output gaps

A

They are useful to interventionist governments

25
What does hysteresis cause
It causes a shift in the LRAS curve to the left
26
What are the ideas that explain the trade cycle
The multiplier and accelerator Speculative and herd behaviour Asset market bubbles Credit/debt cycles
27
What is the multiplier
It is a concept that says that an initial change in someones income causes a change their spending which affects other peoples income
28
What affects the size of the multiplier
The size of the leakage rate in the economy the greater the leakage rate the smaller the multiplier
29
What are the 3 things that make up leakage rate
marginal propensity to save marginal rate of tax marginal propensity to import
30
What is the equation for the multiplier(k)
1/leakage rate
31
What is the marginal propensity to consume
It is the likelihood of spending a part of income change in consumption / change in income
32
What is the marginal propensity to save
It is the likelihood of saving a part of income change in savings/change in income
33
what is mps + mpc equal to
1
34
What does a simple economy mean
No international trade No taxes
35
What is the equation for change in income
Change in AD x multiplier
36
What is the accelerator definition
It is a measure of the extent to which investment spending changes following a change in the rate of consumer spending
37
What is the accelerator an example of
derived demand
38
Whats the theory of the accelerator theory
In order to keep investment levels increasing each year, consumer spending must accelerate
39
What does the accelerator help to explain
the turning points in the trade cycle
40
What is the evaluation of the accelerator theory
If firms have spare capacity, then firms won't need to invest There may be lags between changes in demand and changes in capital Firms may not invest because of business confidence The accelerator applies more to the secondary industry
41
What are assets
Tangibles bought by investors not for their use but in hope that they will increase in value over time
42
How are assests moved around
They are traded in respective markets but are substitutes for one another for any speculators trying to store wealth
43
What are asset markets like
They are prone to volatile pricing activity with price surges (bubbles) followed by sharp downward correction (crashs)
44
How does a bubble form
It forms when asset prices are driven beyond the point where they reflect the underlying value of the asset
45
What are examples of asset market crashes
Bitcoin crash in 2020-21 The US houding bubble that caused the global recession of 2008-09
46
What explains the volatility of asset markets
Herd behaviour information uncertainty
47
What are the stages of asset bubbles and crashes
The upswing - increase in value The pop - the fall in value The bounce - the recovery of price
48
What are the implication of asset markets in the real economy
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
What do credit markets allow to happen
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
What are the effects of credit markets on the trade cycle
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
What is the classical economists view of stabilising the macro-economy
Automatic self correction Too much information failure to make effective changes
52
How does the economy self correct
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
What is the classical view of interference by governments
It makes the economy worse and de-stabilises the recovery mechanism
54
Why does interference make the economy worse at recovering
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
What is the problem with output gaps
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
What is the problem with the multiplier
Hard to measure as it isn't constant Need to predict future leakage rates
57
What is the problem with time lags
It means that policies don't take effect instantly
58
What are examples of time lags
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
How long are time lags normally
18 months to 2 years
60
What the problem with crowding out
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
What is the quantity Theory of Money
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
What is the relationship between quantity of money in circulation and the average price level
Direct relationship
63
Who developed the Quantity Theory
Irving Fisher
64
What is the Fisher identity or equation of exchange
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
What is the velocity of circulation of money
The average number of times a unit of currency changes hands in a year
66
What 2 assumptions turn the Fisher identity into the monetarist theory
The velocity of circulation of money is stable The volume of output produced in an economy is stable
67
What does the Monetarist theory suggest then
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
What were the policy implications of the monetarist theory
Governments who wanted to control the price level would restrict the change in money supply to match the short run growth of output
69
What are the challenges to the monetarist theory
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
What are the economic costs of inflation
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
What is the effect of inflation on UK competitivness
Inflation causes a loss of price competitiveness in international markets AD falls from falling exports
72
What is the evaluation of the effect on UK competitivness
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
What is the wage price spiral
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
What is the evaluation of the wage price spiral
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
What is the redistribution of income from savers to borrowers
Inflation causes a reduction in the real value of savings when real interest rates are negative The real value of debt is diminished
76
How will consumers and businesses on fixed income lose out
Fixed pensions have their real value diminished The state pension is normally adjusted for inflation each year
77
What is the evaluation of consumers and businesses on fixed incomes losing out
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
How can inflation disrupt business planning
It causes uncertainty about the future which makes planning hard This may have a negative impact on the level of planned investment
79
How can inflation distort the operation of the price mechanism
Results in inefficient allocation of resources When inflation is volatile, consumers and firms won't have enough information to make good decisions
80
What is the evaluation of the disruption of business planning
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
What are shoe leather costs/ search costs
Inflation makes it harder for consumers to find the best deals and see relative prices This extra brings opportunity costs
82
What is the evaluation of shoe leather costs
This is a very small impact of inflation Price comparison websites reduces the search cost
83
What are menu costs
They are the extra costs to firms of changing price information This is important to firms with bulky catalogues
84
When is inflation the worst
High, volatile and unanticipated Open economies with large amounts of people on fixed incomes Wage price spiral
85
What are the economic benefits of inflation
Encourage investment Falling debt values Rising Asset Values - Wealth Effect Lack of inflation leads to low real output and employment Money illusion
86
How does Inflation encourage investment
Profits may be eroded sitting in banks at negative real interest rates Firms decide to invest the money instead
87
What is the money illusion
Inflation allows the government to increase nominal spending and reduce real spending Allows the government to operate negative interest rates
88
What is deflation
A sustained fall in the general price over time Negative Inflation
89
What are the 2 types of deflation
Benign Malign
90
What is benign deflation
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
What is malign deflation
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
What is deflationary expectations
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
What is the disadvantage of both deflations
It raises the real value of debt This makes it more expensive for borrowers and causes increased opportunity costs in other spending areas
94
What is another disadvantage of both deflations
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
What is the equation for real rate of interest
Nominal roi - inflation rate
96
What country has experienced malign deflation
Japan
97
What were the Prime Ministers 3 main economic policies to remove deflation
Negative central bank interest rate and QE Expansionary Fiscal Policy Supply side structural reforms making markets more efficient
98
What does Negative central bank interest rate do
Commercial banks are charged to hold money with the Bank of Japan This incentives them to lend the money out
99
What is quantitative easing QE
The central bank pumping liquidity into the economy by buying bonds from existing holders
100
What is the short run Phillips curve
A inverse non-linear relationship between inflation rate and unemployment rate Developed by AW Philips Inflation y-axis unemployment x-axis
101
What explains the short run Phillips curve relationship
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
What did the short run Phillips curve mean for governments
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
What is the natural rate of unemployment
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
What is the long run phillips curve
A vertical line positioned at the economies natural rate of unemployment No trade-off between inflation and unemployment
105
How does the long run Phillips curve work
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
What are the policy implications of the Long Run Phillips Curve
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
Whats the point of inflation targeting
It shows a commitment to keeping inflation under control Achieving the target will reduce inflationary expectations
108
Does it matter if the inflation target is missed
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
Why isn't the inflation target 0%
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
