2.4.4 Multiplier + Equations Flashcards
What is the calculation for the multiplier ratio?
what does the multipler ratio tell us?
how much GDP will increase following an initial injection into the economy
what does marginal propensity to consume mean?
how much consumers are willing to spend if given an additional £1
* if homeless man given £1 and spends 80p, them MPC is 0.8
* only consu,ption within our economy
the lower MPC means less likley to spend, more likley to save
what is the muliplier effect?
initial injections promote further rounds of spending, causing aggregate demand to increase by more thna the initial injection
what is marginal propensity to withdraw?
how much consumers are likley to save if given £1
* MPC+MPW=1
What are the four ways of calculating the muliplier ratio?
what is marginal propensity to withdraw
- MPW=MPS+MPm(imports)+MPT
- Proportion of additional £1 spent on withdrawals(savings, imports,taxes)
Uk exports became cheaper, explain the multipler effect?
- demand for exports increases (injections)
- exports are component of AD, AD increases
- increase in number of people employed to export
- workers will spend, increasing consumption
- increasing AD
- firms with increased revneu from consumption may wish to expand and increase investment
- increasing AD
- this may emply more jobs, consumption…………….repeat
how could the multipler effect be made larger?
- if MPC was larger
- initial injection is larger
marginal propensity to save
the proportion of additional income that is saved
marginal propensity to import
the propertion of additional income that is spent on imports
define marginal propensity to tax
the proprtion of additional income that is taxed
define marginal propensity to consume
the proprtion of additional income that is sepnt on the goods in the economy (consumed)
define marginal propensity to withdraw
the proprtion of additional income that is withdrawn from the economy (saved, taxed or spent on imports)
what are ‘aggregates’?
refers to ‘totals’
eg: total unemplyment
total spending on goods/services -rather than the spending on a particular good
coz MACRO - so overall picture
