Doesn't consider inflation
26
What are the 4 major economic issues?
``` Economic growth Full employment Price stability, low inflation rates External equilibrium, balance of payments (+ Quality of life) ```
27
Define economic growth
GDP increases for 2 consecutive quarters
28
Define recession
GDP decreases for 2 consecutive quarters
29
What do we define as full employment
Less than 3-4% unemployment
30
Define frictional unemployment
Occurs from inevitable delay in finding new employment in a free market
31
Define structural unemployment
Occurs due to a permanent shift in the economy
32
What does (X-M) > 0 mean?
An economy has more revenue from exports than expenditures from imports
33
What does HDI asses?
Knowledge Longevity Income
34
Gini coefficient
Shows the income inequality (close to 0 is more even)
35
Define MPC
Marginal propensity to consume is the percentage of income allocated to the consumption of domestically produced goods and services
36
What is the multiplier effect (with reference to mpc)?
As money is injected in the economy it is distributed around the circular flow of income. However, households do not spend all of it and it keeps going around like this, becoming multiplied
37
What is the equation to calculate the multiplier?
Multiplier (k) = 1/1- MPC
38
Define interest rate
Cost of borrowing and the return from savings
39
What was Keynes' opinion on government spending?
It is positive as it injects money into the circular flow of income and causes the multiplier effect
40
What did Keynes believe about savings?
That they are a bad idea as often the real income will fall over time
41
What is the paradox of thrift?
As interest rates are almost always lower than inflation, saving money makes your real income decrease.
42
What was Hayek's opinion on government spending?
He believed it infringed on civil liberties and that it caused people to feel as though they had more money and thus spend more, putting them in debt
43
What did Hayek believe about savings?
That it was paramount as a tool for individuals to be independent of the main government
44
Define aggregate demand
Total spending on a country's over a period of time at a specific level of prices
45
How do we calculate aggregate demand?
Use the expenditure method of GDP | AD= C+I+G-(X-M)
46
Define fiscal policy
Government spending and taxation
47
What are the two types of consumable goods?
Durable | Non durable
48
What are durable goods?
Goods that do not require constant consumption for example cars.
49
What are non durable goods?
Goods that require constant consumption, such as food.
50
Describe an aggregate demand curve
The x axis is Real GDP and changes are represented by the letter 'y'. The y axis is Price level and changes are represented by the letter 'p'. Aggregate demand curve is downwards sloping
51
What do we call a movement right down the aggregate demand curve?
An extension of AD
52
What do we call a movement left up the aggregate demand curve?
A Contraction of AD
53
What 3 effects affect AD?
Wealth effect Trade effect Interest rate effect
54
Describe the wealth effect
As price level decreases, purchasing power increases
55
Describe the trade effect
If exports become more competitive, imports become less competitive and vice versa
56
Describe the interest rate effect
If interest rates rise, aggregate demand begins to fall as borrowing is essentially becoming more expensive. This can happen due to increases in price
57
How do banks prevent inflation when prices are high?
Increase interest rates
58
When does the AD shift left or right?
When there is a change to a component other than price
59
What does it mean for the consumption of durable goods if the consumer confidence is low?
It is also low
60
Which factor is most likely to shift an aggregate demand graph?
Consumption
61
How can the government effect the consumption of durable goods?
Investment | Taxes
62
What factor directly effects investment?
Interest
63
What does it mean for investment is interest falls?
Investment becomes cheaper and the AD shifts right
64
Describe the effect on AD if tax decreases
Shifts right
65
Describe the effect on AD if tax increases
Shifts left
66
Describe the effect on AD if government spending decreases
Shifts left
67
Describe the effect on AD if government spending increases
Shifts right
68
Define the long run in macroeconomics
A period of time during which no price of any factor of production is fixed
69
What level of taxation occurs in a government with no intervention?
Low taxation
70
What level of taxation occurs in a government with high intervention?

73
Give an example of a neoclassical economist
Friedrich Hayek
74
Give an example of a Keynesian economist
John Maynard Keynes
75
What does a neoclassical LRSA graph look like?
The LRSA is perpendicular to GDP
76
What does a Keynesian LRSA graph look like?
The LRSA begins parallel to GDP and then curves upwards, however, if the economy moves into the vertical section they will be in hyperinflation
77
What are policies that can be imposed to reduce expenditure?
Contractionary monetary policy (Increase IR) Contractionary fiscal policy (decrease government spending, increase in tax)
78
What are policies that can switch expenditure (protectionist policies)?
