Suppose consumers' disposable income increased by $341 billion and their spending increased by $299 billion. What was the MPC?
Suppose the government increases education spending by $30 billion. If the marginal propensity to consume is 0.90, how much will total spending increase?
Solution:-
(a). Calculate MPC:-
MPC = Change in consumption / Change in Disposable income
= $299 / $341
= 0.88
(b). Calculate Total Spending:-
Government spending multiplier = 1 / (1 - MPC)
= 1 / (1 - 0.9)
= 1 / 0.1
= 10
Therefore, total spending would increase by = multiplier x education spending
= 10 x $30 billion
= $300 billion.
