A simplified economy is specified as follows:
A. Goods market, all values C, I, G and NX values are in billions
of C$:
Consumption Expenditure: C = 150 + 0.8(Y-T)Investment
Expenditure: I = 1,300 - 420iGovernment Expenditure: G =
340Lump-sum Constant Taxes: T = 340Exports: 90Imports: 10
B. Money market, all Md values are in billions of
C$:
Interest Rate: i = 0.09 or 9%Money Demand: Md = 780 -
1,900i
Note: Please keep your answers accurate to two
decimal places.
a) Given the above information, solve for the
following: the equilibrium Y, the money supply M, the consumption
expenditure C, and the investment expenditure I.
Y = 0M = 0C = 0I = 0
Now suppose there is an impending federal election, and the
government promises to use fiscal policies to stimulate the
economy.
b) Find the value of the goods market
multiplier.
Goods market multiplier = 0
c) Let G rise to 420. Solve for the new
equilibrium Y and C.
Y = 0C = 0
d) Demonstrate how the increase in G affects the
economy through the multiplier. Use three rounds of effects to
demonstrate the multiplier effects. Let the first round be related
to health care spending, the second round related to clothing, and
the third round related to food.
Round 1 -> As the government wants to spend $1 (or $1
billion)
on health care, it demands the production of health care
equipment
such as hospitals, medicine, equipment, etc. to be built and
sold to
the government. So as ΔG = 1, the production ΔY =
0
. This Y is the
income to the nurses, doctors, construction workers, etc.
Round 2 -> As the nurses receive their new income of Y =
0
, theyspend
0
% of this $
0
on clothing ->
0
cents worth of clothing wouldbe produced, or ΔY =
0
-> this
0
cents would be the income of the
workers involved in making the clothing.
Round 3 -> As the clothing workers receive their new income
of
Y =
0
, they spend
0
% of this
0
cents on food -> (
0
)(
0
) =
0
or
0
cents worth of food would be produced, or ΔY =
0
-> this would
be the new income to the food workers.
e) Now consider monetary policies only. Suppose
the BOC wants to drop the i to 0.04 or 4%, with G still at
$340. Solve for the new I and the ΔI compared to when i =
0.09. Given the multiplier, how much would you expect Y to rise
by?
I = 0Change in I = 0Change in Y = 0
f) Given the changes in (e), find the equilibrium
Y, the money supply M, the consumption expenditure C, and the
investment expenditure I.
Y = 0M = 0C = 0I = 0
g) Complete the following statement to demonstrate
how the drop in i affects the money supply, then I, then
Y, then C.
As i decreases -> ΔM (Select One) -> ΔI (Select One) ->
ΔY (Select One) -> ΔC (Select One)
