2.4 National income Flashcards
2.4.1 A)
What does notional income measure
The total value of goods / services provided in a year
2.4.1 A)
How do households interact with circular flow of income
Gives firms factors of productions (labour)
Goods/services by households
(Check notes for diagram)
2.4.1 A)
How do firms interact with circular flow of income
spend money on factors of income (wages, rent)
(Check notes for diagram)
2.4.1 B)
Distinction between income and wealth
income is seen as a flow of money whereas wealth is seen as a stock of assets
wealth can be measured at any particular point in time , whereas income is weakly / monthly .
2.4.1 B)
How can a consumer increase wealth
Sacrifice current consumption this can be seen as opportunity cost
wealth often generated income
2.4.2 A)
What is an injection into circular flow of income
money entering the economy
(government spending , investment , export)
2.4.2 A)
What is an withdrawls into circular flow of income
money leaving the economy
(saving , taxation , imports)
2.4.2 A)
What can have big impacts on circular flow of income and what can it result it
Policy decisions can cause economic growth .
2.4.4 A)
What is the multiplier effect
An increased in AD caused by an ^ injection can lead to further inc in national income
for ex if 100m spent on invesment and lead to another 90m being spend by those effected by the investment MPC will be 0.9
2.4.4 A)
How is the size of the multipler determined
By how much of an ^ in income people spend (MPC).
V leakage ^ mpc ^ multipler
2.4.4 B)
Why is the multipler able to work
What other types of multiplier can you have
due to circlur flow of income one persons spending is anothers income
can also have neg multipler due to withdrawls
2.4.4 C)
What effects does multipler have on the economy
faster economic growth
will be time lag as ppl dont spend money straight away
2.4.4 D)
What is MPC
What is MPS
What is MPT
What is MPM
What is MPW
Marginal propensity to consume, ^ comsumption derived from ^ in income
Marginal propensity to save, ^ save derived from ^ in income
Marginal propensity to tax, ^ tax derived from ^ in income
Marginal propensity to import, ^ import derived from ^ in income
Marginal propensity to withdraw ^ leakages derived from ^ in income
MPW = MPS + MPT + MPM
2.4.4 E)
What is the mulitplier forumla
MPW = MPS + MPT + MPM
1/(1-MPC) = 1/MPW
EX: MPC = 0.9 on 50k gov spendinging whats the total
1/(1-0.9) = 10
10*50k = 250k
2.4.4 F)
The significance of the multiplier for shifts in AD
Multipler = ^ AD but must be sufficent spare capacity
IF AS is perfectly inelastic then only affect will be ^ in price
^ Es V price ^ output.
