) tells us
A) the fraction of income consumed.
B) the percentage of income consumed.
C) the level of induced expenditures.
D) the fraction of an additional dollar of income that is spent.

In the aggregate expenditure model, if the

According to the multiplier equation, an increase in the marginal propensity to
consume
A)
raises output because it leads to an increase in autonomous expenditure.
B) reduces aggregate expenditure because it reduces the multiplier.
C) increases output because it increases the multiplier.
D) increases aggregate expenditure because it increases autonomous
expenditure.
