11) When income tax rates are reduced, households tend to spend part of the additional take-
home pay they receive (as a result of the lower rates) and save the rest. This action also enlarges

a consequence, we can say that a reduction in income tax rates will tend to
A) increase national saving.
B) increase both private saving and public saving.
C) increase public saving.

C) increase both consumption spending and private saving.
D) increase consumption spending, but reduce private saving.
E) decrease consumption spending, but increase private saving.
15) A reduction in personal income taxes tends to
A) increase private saving because when taxes are reduced households find themselves with
more disposable income and they tend to save a portion of that income.
B) lower private saving because when taxes are reduced households anticipate further tax
reductions and defer saving for the future.
C) lower private saving because the tax reduction enlarges the federal government's budget
deficit or reduces the size of its budget surplus.
D) increase public saving because the tax reduction enlarges the federal government's budget
deficit or reduces the size of its budget surplus.
E) None of the above are true.
16) If a tax increase resulted in a larger surplus in the federal budget, this action would probably
A) increase private saving.
