Question 2
Complete
Mark 1.00 out of 1.00
Which of the following is correct
regarding the effect of expansionary
monetary policy in the Keynesian model?
a. The consumption function
swivels downward showing a fall
in aggregate spending and
income.
b. The aggregate spending curve
will shift downward showing a
fall in aggregate spending and
income.
c. Investment spending will
increase, which is shown by an
upward shift of the aggregate
spending curve.
d. Firms will choose to invest less.
An expansionary monetary policy occurs
when the monetary authorities reduce the
repo rate, thereby reducing the interest
rate. As the interest rate (cost of
borrowing) falls, investment spending
increases. The increase in investment
spending will be shown by an upward
shift of the aggregate spending curve.
Firstly, a downward swivel of the
consumption function is caused by an
increase in tax rate and not interest rate,
which then results in a fall in aggregate
spending and income. Secondly, rms will
invest more due to the fall in cost of
borrowing.

Question 3
Complete
Mark 1.00 out of 1.00
Which of the following is correct
regarding the effects of expansionary
scal policy?
a. The size of the multiplier will
increase.
b. Autonomous spending and the
level of income will decrease.
c. The slope of the consumption
function will decrease due to a
rise in the tax rate.
d. There will be a leakage of money
out of the circular ow of
income, spending and
production.
An expansionary scal policy occurs
when government spending is increased
and taxes decreased. Since taxes affect
the slope of the consumption function, a
reduction in taxes increases the slope of
the consumption function, thus causing
the size of the multiplier to increase.
Autonomous spending and equilibrium
income will increase due to the injection
of money in the circular ow of income,
spending, and production.

c. a

will increase the equilibrium level closer
to the full employment levels.
