Q

What does MPS represent?

A

With every extra pound, how much they save of it

17
Q

Marginal propensity to tax =

A

Change in tax / Change in income

18
Q

What does MPT represent?

A

With every extra pound earnt, how much spent on tax
Can also mean marginal tax rate

19
Q

Marginal propensity to import =

A

Change in imports / Change in incomes

20
Q

What does MPM represent?

A

Proportion of extra pound earnt spent on imports

21
Q

The multiplier

A

An initial change in an injection or leakage that leads to a much greater final change in real national income. One person’s consumption is another’s income

22
Q

How does the multipier work?

A

Govt buolds New hospital for £50bn -> Govt spending rises by £50bn, AD and real GDP rise by £50bn -> Govt spends £35bn of the money ona construction firm -> Firm spends £10bn on investment (a component of AD), Invetsment (I) rises by £10bn, Firm spends £5bn on workers who receive higher incomes and spend, Consumer spending rises by £5bn (another component of AD) -> AD risen by £65bn (50bn + 10bn + 5bn) from £50bn -> if spending rises by £50bn, will be a rightward shift in AD, each stage of the multiplier effect will be viewed to add another rightward shift od AD each one smaller than the last

23
Q

What happens if MPC is high?

A

The multiplier is high - more money is passed on at each stage

24
Q

What happens if taxes rise?

A

More money is leaked -> MPC must fall -> multiplier falls

25
Q

Multiplier formula

A

Multiplier = 1 / (1-MPC)

26
Q

Marginal propensity to withdraw =

A

MPS + MPT + MPM
