Macro Yellow Booklet Flashcards
When evaluating which of the components of AD is most important?
Consumption- is two thirds of aggregate demand.
What does economic performance measure?
Economic Performance measures the success or failure in achieving economic policy objectives
What are seasonal fluctuations?
variations of economic activity resulting from seasonal changes in the economy
What is the actual rate of growth from the economic growth diagram?
Real GDP/ real output produced by an economy (backed by AD)
What the trend rate of economic growth?
Underlying rate of growth- potential growth/ output capable by an economy if producing at full capacity.
Define positive output gap?
the level of actual real output in the economy is greater than the trend output level
Define negtaive output gap?
the level of actual real output in the economy is lower than the trend output level
What happens in the recovery stage of the economic cycle?
- economic activity goes up
- Optimism- bussiness + consumer confidence
- Consumer spending goes up
- Firms investment goes up
- Imports rise and people have more income and so want to buy more imported good
What happens in the Boom stage of the economic cycle?
- economic activity peaks
- growth is high
- firms expanding (investment)
- full employment
- output reaches full capacity
- AD>AS economy overheats
What happens in the downturn stage of the economic cycle?
- economic activity falls below the trend rate of growth
- firms cutback
- investment falls
- output falls
- employment falls (spare capacity)
- Less imports (BOP improves)
What happens in the recession stage of the economic cycle?
- employment falls further
- some firms bankrupt
- low AD
- Inflation may fall further could result in deflation
- bank lending falls
- output falls
- investment falls
List the causes of changes in the phases of the Economic Cycle
- Fluctuations in AD
- Supply side factor
- Role of speculative bubbles
- Political business cycle theory
- External shocks hitting the economy
- Multipler and accelerator interaction
Explain how the role of speculative “price” bubbles cause changes in the phases of the economic cycle
When people realise that house
prices and/or share prices rise far above the assets real values, asset selling replaces asset buying. This causes the speculative bubble to burst, which in turn destroys consumer and/or business confidence. People stop spending and the economy falls into recession. The resulting cyclical instability is made worse by the excessive growth in credit and levels of debt.
Explain how the political business cycle theory causes changes in the phases of the economic cycle
In democratic countries, general elections usually have to take place every 4 or 5 years. As an election approaches, the political party in power may attempt to buy votes’ by engineering a pre-election boom. After the election, the party in power deflates aggregate demand to prevent the economy from overheating, but when the next general election approaches, demand is once again expanded.
Explain how external shocks hitting the economy cause changes in the phases of the economic cycle
Economic shocks, divide into ‘demand shocks’, which affect aggregate demand, and ‘supply shocks’ which impact on aggregate supply In some cases, an outside shock hitting the economy may affect both aggregate demand and aggregate supply.
•A commonly example is the effect on other countries of a war in the Middle East. Not only might the war affect business confidence in a country such as the UK (a demand shock), it may lead to an oil shortage which increases businesses’ costs of production. This would be a supply shock.
Explain how multipler and accelerator interaction causes changes in the phases of the economic cycle
Business cycles may be caused by the interaction of two dynamic processes: the multiplier process, through which an increase in investment leads to multiple increases in national income; and the accelerator, through which the increase in income induces a change in the level of investment.
Thus the relationship between investment and income is one of mutual interaction; investment affects income (via the investment multiplier), which in turn affects investment demand (via the accelerator process), and in this process income and employment fluctuate in a cyclical manner.
How is economic growth measured?
economic growth is measured by the annual % change in real GDP.
Define short-run economic growth
growth of real output resulting from using idle resources, including labour, thereby taking up the slack in the economy.
Define long-run economic growth
an increase in the economy’s potential level of real output, and an outward shift of the economy’s production possibility frontier.
What is the difference between SR and LR growth? How would you show this on a PPF?
SR growth is an increase in Real GDP by using spare capacity until the productive potential (capacity) of an economy is reached. Where as LR growth is an increase in productivite capacity/ potential of an economy. It is a outward movement of the PPF cruve or LRAS cruve.
What are the causes of economic growth in demand
An increase in any of the determinants of AD will incentivise firms to produce more so increasing real GDP in the short run. External shocks also effect deamnd side determinants.
The effect on the price level depends on the slope of the AD curve.
What are the causes of economic growth in the short run SRAS- supply side?
•Political Stability can provide a postive shock to growth
•Decrease wage rates
Short term growth takes account of the spare capacity/ slack in the economy. This will increase output in the SR but is not sustainable in the LR.
What are the causes of economic growth in the long term LRAS- supply side?
•Increase in labour participation (quantity of labour)
•Increase quality of labour to raise productivity (education, apprenticeships, training)
•Increase Investment on capital (expansion, replacement, newer technology)
Long term growth actually increases the productive capacity of the whole economy. Increase productivity= reduced unit costs as efficiency rises
Will economic growth increase or reduce income and wealth inequality?
It will depend upon how the income is redistributed and where the economic growth occurs. If the income of the rich rises more than the income of the poor then wealth inequality will increase.
Why may inequality be negative for an economy?
- It reduces productivity as human resoruces are depleted. (poorer people may also lose aspirations)
- More money is spent on benefits and looking after these people.
How may the pursuit of economic growth be harmful for the environment?
- uses up finite resources
- more pollution and environmental degradation
- urbanisation and spread of cities reduces agricultural land
What impact may pollution caused by SR growth have on LT economic growth?
Land degradation and depletion of natural respruces means the economy cannot grow in the LR as these rescoures are fintie.
What are the benefits of economic growth?
- Increases standard of living
- Increases life expectancy and reduces diseases
- Route out of poverty- creates jobs
- Taxes pay for better public and merit goods
- Postive multiplier- more bussiness confidence leads to investment and even more growth
- Access to training and education increases
What are the costs of economic growth?
- uses up finite resources
- more pollution and environmental degradation
- raises commodity prices
- destroys local cultures and communities
- widens inequality gap with income and wealth
- raises inflation
- encourages population growth which means more mouths to feed
- worsens BOP- trade deficit (more money so we import more)
Define unemployment
The number of people willing and able to work at the market wage rates but unable to find jobs.
Why is there a difference between the claimant count and the labour force survey?
- those ineligible for benefits due to higher savings of a high earning parnter
- some people do not want the stigma of claiming benifits so will not be included
- LFS includes 16 & 17 year olds
What are the main UK measures of unemployment?
- claimant count
* labour force survey
What are the 5 types of unemployment?
- frictional.
- cyclical.
- seasonal.
- structural.
- classical
Define frictional unemployment
unemployment that is usually short term and occurs when a worker switches between jobs.
(The search theory of unemployment)
Define structural unemployment
long term unemployment occurring when some industries are declining, even though other industries may be growing.
What factors may cause structural unemployment?
- occupational and geographical immobility of labour.
* Automation (robots replace labour) reduces the demand for labour
Define cyclical unemployment
unemployment caused by a lack
of AD in the economy and occurs when the economy goes into a recession or a depression.
Define involuntary unemployment
when workers are willing to work at current market wage rates but there are no jobs available
Define voluntary unemployment
occurs when workers choose to remain unemployed and refuse job offers at current market wage rates
What is the keynesian argument for cyclical unemployment?
•If low AD is persistant it can lead to mass unemployment or a higher accepted level of unemployment unless there is intervention
-long term and involuntary
What is the free market critique for cyclical unemployment?
•It is short-term, self correcting as long as prices and wages are flexible
-Markets will return to equilibrium without intervention.
Define seasonal unemployment
unemployment arising in different seasons of the year, caused by factors such as the weather and the end of the Christmas shopping period
What is real wage unemployment?
a type of disequilibrium unemployment caused by real wage rates being too high to clear the labour market, resulting in excess supply of labour.
What are real wages?
Wages that have been adjusted for inflation, a real wage measures the amount of goods and services that can be bought
