A shift in the aggregate expenditure function from AE0 to
AE1 could be caused by (parallel up) -Answer- an increase in desired investment expenditures
Suppose aggregate output is demand−determined.
If the simple multiplier is 4 and there is a $10 billion increase in planned investment spending, then
equilibrium income will ________ and the marginal propensity to spend must equal ________ -Answer-
increase by $40 billion; 0.75
In a simple macro model, an increase in households' wealth is generally assumed to -Answer- cause an
upward shift in the aggregate consumption function
The consumption function is based on the assumption that as real disposable income rises, aggregate
desired consumption -Answer- and desired saving will both rise
Consider the following aggregate expenditure function: AE = $300 billion + (0.87)Y. Assuming that we
have no government, no international trade and desired investment is autonomous and is equal to $56
billion, then which of the following is the correct statement of the consumption function? -Answer- C =
$244 billion + (0.87)Y
Consider the following information for an economy with
demand−determined output and a constant price level. There is no government or foreign trade.
1. Y = C + I
2. C = 100 + 0.8Y
3. I = 200 -Answer- 1500
