income
look at what is learnt
income measures
the flow of money a person or economy receives each year.
assets
things you own
wealth
the sum or stock of all your assets added up
over time income can
turn into wealth, by buying assets
step 1 in circular flow of income
Firms buy factors of production, like labour and land, from households. And in return, they pay households factor incomes, like wages and rent.
step 2 in circular flow of income
Households spend the factor incomes on goods and services produced by firms
income must =
expenditure = output
Explain why national income equals national expenditure which equals national output.
The total spending (national expenditure) from households across the economy must come from the total income (national income) they earn. Households spend (national expenditure) on the total output (national output) of goods and services produced by firms in the economy.
National output is equal to national incomes. So, if national output is rising then
national incomes must also be rising.
real GDP is
a statistic that measures national output, it measures all the stuff really being produced in an economy
examples of leakages/withdrawals from the circular flow
savings SIT
taxation
imports
examples of injections to the circular flow
gov spending GIX
exports
investment
leakages > injections
economy will shrink because money is leaving the circular flow - real GDP decreased
injections > leakages
economy will grow, because money is entering the circular flow - real GDP increase
leakages = injections
real GDP stays the same
aggregate demand
demand for all goods in an economy added up
components of AD
C + I + G + (X-M)
on average percentages of each
C - 60%
I - 14%
G - 25%
X-M - 1%
gross investment
Gross refers to the total amount (in this case, the total amount of the original investment).
net investment
the value of investment after depreciation
Net refers to the total minus any deductions (in this case, the amount of depreciation).
equation for net investment
Net Investment = Gross Investment - Depreciation
When the price level increases,
real GDP decreases.
when price level goes down it causes an
extension in AD, increase in real GDP
