Assume that a hypothetical economy with an MPC of .8 is experiencing severe recession. By how much would government spending have to increase to shift the aggregate demand curve rightward by $25 billion?
How large a tax cut would be needed to achieve this same increase in aggregate demand? Why the difference?

Expenditure multiplier is given as 1/(1 - MPC). Tax multiplier is given by MPC/(1 - MPC).
a. Given that MPC is 0.8, the expenditure multiplier is 1/(1 - 0.8) = 1/0.2 = 5. To obtain a shift in AD of $25 billion we would need an expenditure change that is one-fifth this amount (since the multiplier is 5), and thus government has to increase spending by 25/5 = $5 ...
This solution determines one possible combination of government spending increases and tax decreases that would accomplish this same goal.
