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?

Solutions

Expert Solution

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.
