Q

What is the problem with increasing the size of the labour force and give reasons for this (+ example):

A
  • It will not necessarily increase economic welfare
  • Increased income has to be shared out amongst more people so there is little/no change in income per person
  • Leisure time has to be given up for some people to do this eg. women coming back to work

Q

Examples of demand-side shock:

A
  • House prices rise too high
  • Stock market crashes
  • Central bank sharply increasing interest rates
  • Sharply raising taxes
  • Cutting gov spending
  • World economy is in recession –> causes UK to go into recession
  • Sharp rise in value of pound

25
How does a rise in house prices lead to a trade cycle?
- If prices are too high - Demand collapses - This causes sharp fall in house prices - Decreases consumer spending and therefore lowers AD
26
How does a stock market crash lead to a trade cycle?
- Reduces wealth of individuals - Decreases consumer spending - Lowers AD
27
Why may interest rates and taxes be increased?
Possibly to combat inflation
28
How does raising interest rates and taxes cause the trade cycle?
- Less consumer spending - Lower AD
29
How does a sharp rise in the value of the pound cause the trade cycle?
- Reduces competitiveness - Lowers AD
30
Examples of supply-side shocks:
- Large rise in world commodity prices - Outbreak of TU militancy
31
How does a large rise in world commodity prices cause the trade cycle?
- Raises price in UK - Causes rise in import costs - Reduces AS
32
How does an outbreak in TU militancy cause the trade cycle?
- Causes large wage increases - Reduces AS
33
What do the two lines on a trend rate of growth graph represent?
- Actual level of real GDP (trade cycle) - Trend level of GDP (estimated amount)
34
Output gap:
Difference between actual r level of real GDP and estimated long term value at a point in time
35
What does a negative output gap mean?
There is spare capacity
36
How is a positive and negative output gap filled?
- Positive --> Long-run economic growth moving LRAS right/ Recession shifting AD or SRAS down - Negative --> Using spare capacity
37
What are the issues present when estimating the size of an output gap?
Difficult to estimate as: - Economists do not know exact position of LRAS curve - Initial estimates of GDP are almost always inaccurate as they are constantly revised
38
Long term benefits of economic growth:
- Increased life expectancy - Increased food security - Improved housing standards - Better literacy
39
Costs of economic growth:
- Inflation - Disease of affluence - Inequality - Current account deficit - Pollution - Use of non-renewable resources
40
What is the biggest argument against economic growth?
It is unsustainable
41
Sustainable growth:
Growth in the productive potential which does not negatively impact the future generations
42
In what way is economic growth argued to be unsustainable?
- Likely to use up more non-renewable resources - Associated w/ worser environmental effects
43
What does economic theory suggest as an argument against this?
The growing scarcity of resources will result in: - Lower demand, therefore fall in consumption --> price mechanism conserves resources - Becomes profitable to explore new supplies - Producers + consumers switch to substitutes - Gov respond to pressures
44
What is one limitation of the responses of gov?
Usually too slow to act
45
What is the Easterlin Paradox?
Idea that increases in GDP do not lead to increases in happiness
46
What is the impact of economic growth for consumers, firms, gov, and environment?
- Consumers --> rising incomes - Firms --> Changing technologies create opportunity for increased sales - Gov tax revenues rise due to rising incomes - Less pollution (in developed countries) due to better technology
47
What are the two main issues w/ validity of GDP/GNI?
- National income stats do not measure true value of output produced - Living standards are closely related to variety of factors excluded in GDP/GNI
48
Why don't GDP/GNI accurately reflect the true value of output?
- Doesn't include non-marketed output - Doesn't include output sold in underground markets - Have differing domestic price levels
49
Non-marketed output:
- Goods/Services that are not sold in market and do not generate any income - Likely to be greater in less developed countries
50
Underground market:
- Goods/Services that are sold in markets and do generate incomes but are unrecorded - Illegal/Legal goods
51
How can the issue of missing underground markets be solved?
Estimates of their size can be made and added to GDP/GNI figure
52
How can the issue of differing domestic price levels be overcome?
Conversion into a single common currency know n as purchasing power parity
53
Why don't GDP/GNI accurately reflect living standards?
- No distinctions about composition of output - Doesn't reflect achievements in education, health and life expectancy - No info on: --> distribution of income and output --> increased leisure --> value of negative externalities --> depletion of natural resources --> improvements in quality of goods and services
54
GDP/GNI doesn't make distinctions about composition of output. Why does this not accurately show living standards?
- It includes the value of all good and services - As a result, it does not show to what degree each product contributes to living standards
55
What is an alternative measure that will show the levels of education, health and income levels?
Human Development Index
56
GDP/GNI does not show the distribution of income/output. Why is this a problem?
Regional and wealth inequalities are disregarded, which contributes to living standards
57
Give examples of negative externalities that reflect standard of living and are not included in GDP/GNI:
- Pollution - Toxic waste
58
What does national income tend to be correlated with?
Wealth
59
What is the caveat to the belief that higher incomes correlate to higher happiness levels?
Surgery across countries consistently show that those with above average incomes tend to have higher happiness levels
60
What are the two suggested explanations for the correlation between relative income and happiness?
1) Symbol of social status 3) Above average incomes correlate w/ a number of other factors associated w/ happiness
61
Why do some economists and politicians argue inequality to be positive?
- Encourages incentives to work - Take economic risks
