The multiplier 2.4.4 Flashcards
what is the idea of the multiplier process.
the idea id that an increase in AD is because of an increases injections (exports, government spending, investments)
what happens if the injections increases in the circular flow of income
there would be a larger final change in the total spending of an economy
what happens if the leakages increases in the circular flow of income
if the leakages increases, then the multiplier effects will be smaller, For example when the 2008 recession hit the UK, the saving ratios lose markedly reducing the multiplier effect
What are the effects of the multiplier on the economy
- Multiplier means that the growth can occur quicker, as any injections lead to a bigger increase in national income. injection can be targeted to those who have the biggest MPC in order to increase the size of the multiplier.
- However there would be a time lag between the increase in income and the full effect of that increases as not everyone will spend the money straight away.
Marginal Propensity to Consume MPC
the increase in consumption following an increase in income
Marginal Propensity to Save MPS
the increase in savings following an increase in income
Marginal Propensity to Tax MPT
the increase in taxation following an increase in income.
Marginal Propensity to Import MPM
the increase in imports following an increase in income
formula for the multiplier
1/(1 - MPC)
