What is national economic performance?
This is how a country is doing economically and is used to compare today with the past e.g. How much has economic growth increased/decreased from last year?
What are some measures of economic performance?
- economic growth e.g. If output is increasing, if consumers are spending
- levels of employment: if there are more workers in an economy output is increase and production is more efficient
- inflation: if inflation is too high it will discourage spending
- current account: if there’s a large deficit
- inequality gap: if there is a big difference in income groups with the country
What is aggregate demand?
The total of all demands or expenditures in the economy at any given price. It is also called national expenditure.
What is the national expenditure (AD curve) made of?
- consumption
- investment
- govt spending
- exports minus imports
It’s can be calculated using this formula:
C+I+G+[X-M]
Why is the AD curve downward sloping?
This is because if a household is one a fixed budget and inflation occurred, this means they cannot buy the same amount of good they could before.
The higher the price, the fewer goods will be demanded.
What is the wealth affect?
It is how a consumer feels about their wealth due to certain factors e.g. if price levels increases but the households income of fixed, they would feel less wealthy. This is called the negative wealth effect.
Households react to changes in house prices as well as stocks and share value.
What are “animal spirits”?
This is a concept created by John Maynard Keynes. Animal spirits is another way of saying business confidence. Keynes believed that if firms had more confidence it would lead to higher investment.
Confidence can decrease if interest rates are high or there is a recession.
What the difference between durable and non durable goods?
Durable goods are good which continue to provide service over a long period of time e.g. cars.
Nom durable goods are good used up immediately or over a short period of time e.g. food.
What is marginal propensity to consume (MPC)?
It is the proportion of a change in income spent and can be calculated:
MPC= Change in consumption/change in income
What is the average propensity to consume (APC)?
It’s measures the average amount spent on consumption out of total income. It can be calculated:
APC= consumption/income
What can affect consumption?
- interest rates
- consumer confidence
- wealth effects
- availability of credit
- inflation
- composition of households (age)
What is investment?
Investment is the addition to the capital stock of the economy.
What is the difference between gross and net investment?
Gross investment measures investment before depreciation.
Whereas net investment is gross investment - the value of depreciation.
What is the difference between human and physics capital?
Investment in human capital is investment in workers and their training.
Investment in physical capital is machinery and factories.
What is the accelerator theory?
The idea that investment is linked to changes in output or income in an economy e.g. If the economy is expanding, investment increases to cater for increased demand and produce more goods.
What affects investment?
- business confidence
- the world economy (e.g. If the world economy is booming exports will increase)
- access to credit
- retained profit (70% of investment is financed through retained profit)
- govt regulations
What affects the level of imports in a country?
- real income: as 10% of spending are on imported goods
- exchange rate: if goods are cheaper in other countries
- degree on protectionism with the country: if there’s tariffs or quotas, this can limit imports
What affects level of exports?
- the exchange rate: if gone value of the punt decreases, it is cheaper for foreigners to buy our goods
- state of the world economy: its trade partners are doing well, exports are likely to rise
- degree of protectionism: almost all countries limit goods and services coming into their economies
What does it mean if a good is less competitive?
When a good is less competitive it means that people will not look to buy that good from a specific seller because there are cheaper substitutes.
Why is the AS curve upward sloping?
This is because in the short run, if a firm wanted to increase their output, they would not employ more workers. Instead they would just make their current employees work for longer while paying them by the hour. This will have an affect on the price as the cost of production has increased.
Therefore an increase in quantity causes an increase in price.
What causes a shift in the SRAS curve?
- wage rates
- cost of raw materials
- exchange rates: if imports are or expensive, this will cause an increase in price across the economy meaning supply increases
- productivity: high productivity cause cost of production to be lower.
- taxation: high tax burden leads to an increase in prices
What is the difference between the SR and LR AS curve?
In the short run at least one factor of production is fixed. Whereas in the long run, all factors are variable.
Why (in the classical model) is the LRAS curve vertical?
This is because in the long run their is a limit to how much firms can increase supply due to capacity constraints. Capital equipment is fixed in supply etc.
Therefore it can be argues that AS is fixed at a given level of output.
What is the LRAS curve associated with?
The PPF as it shows the maximum level of output within an economy once all resources are used efficiently.
It is also associated with the trend of growth on the economy. If output is above or below this level, there are output gaps.
