Aggregate Expenditure Flashcards
What is aggregate expenditure?
Defined as the sum of consumption expenditure, planned investment expenditure, government expenditure and expenditure on our net exports.
Formula for aggregate expenditure?
AE = C + I + G + (X-M)
Consumption expenditure?
Largest component of AE (56% of aggregate expenditure)
Household spending
Categorised in three ways: durable (brown and white goods) (+3 years), non durable (food) (<3 years) goods and services (education, transport, recreation).
Goods are tangible, services intangible
Factors affecting consumption expenditure?
Level of disposable income Cost of credit (interest rates) Current stock of wealth Consumer confidence Government economic policy
Disposable income - income after tax.
People with more money gave a lower % of money spent.
Cost of credit
Decrease in interest rates - increases investment spending.
Increase in interest rates - decreased investment spending.
Household of “stock” of wealth
High value of assets = more spending, decrease = less spending.
Consumer confidence
Concerned with changes of economic growth, interest rates and exchange rates.
Planned investment?
Expenditure on capital equipment, factories and tools ➡️ referred to as planned business expenditure.
Housing investment is expenditure on new housing.
Most volatile sector of the AE.
Consists of business and housing investment and inventories ➡️ inventories aren’t included in the formula for planned investment.
Private investment accounted 16%-26% of GDP in 2015.
Government expenditure?
Consists of two types of spending ➡️ G1 and G2.
Current spending (G1) - expenditure on a day to day basis ➡️ health, social welfare, defence and education.
Capital spending (G2) - machinery and infrastructure (roads and railways).
Government expenditure has accounted for 22% of GDP,
It can be used to stabilise macroeconomic fluctuations.
Net exports?
Value of goods and services sold overseas - value of goods and services bought overseas.
Works out how much we spend in Australia.
0.4% of our GDP.
What is the multiplier?
One mans spending is another man’s income - until the change in income is reduced to zero.
1 divided by MPS.
Macroeconomic equilibrium?
Occurs when the level of expenditure in the economy exactly equals the level of output produced, and income from that production.
Meaning there’d be no tendency to change levels of output, income or expenditure.
Expressed as the sum of..
APC and APS
APC - proportion of total income which is spent on consumption.
APS - proportion of total income which is saved.
APS + APC = 1.
Factors affecting planned investment expenditure?
Interest rates
Government policies
Profitability
Technology
Factors affecting government expenditure?
Economic policy objectives ➡️ social policies, health and education.
Automatic changes due to the business cycle.
Stabilises macroeconomic fluctuations.
Factors affecting net exports?
Cyclical factors (e.g. Chinese, Australian growth) Structural factors (e.g. Exchange rates, TOT, international competitiveness)
What does the 45 degree line show us?
Planned expenditure = total income.
Aggregate expenditure = aggregate output.
MPC? Marginal prosperity to consume.
Ratio of any change in income that is spent on consumption.
Change in C / Change in Y.
MPS? Marginal propensity to save.
Any change in income that is saved.
Change in S / Change in Y.
Consumption function formula?
C = a + bY.
C equals consumption spending.
A is the minimum spent if income was zero.
B is the rate of spending.
And Y is income.
AE %’s
Consumption - 56%, planned investment 21%, government spending 23%
What are three types of economic indicators?
With an example.
Leading - building approvals, share prices.
Coincident - retail prices, interest rates.
Lagging - unemployment levels, consumer debt levels.
What is the formula of the multiplier?
1 divided by the MPS
OR
1 divided by 1 - MPC.
