Using the above information, calculate real after-tax returns on the following investments:
(1) $100,000 Guaranteed Income Certificate (GIC), paying 5% interest.
(2) $100,000 invested in a blue-chip stock paying 4.5% dividend yield (assume no opportunity for capital gains)
(3) $100,000 invested in a growth stock paying no dividends but expected to be worth $104,500 next year.
Where should you put your money?

MPN = w = p = Real Wage
One of the properties of the production function is diminishing marginal product: as N increases, MPn falls. If the real wage falls (nominal wage falls, price of output rises) then MPn > w=p and firms will hire more labour which decreases MPn . Hiring stops when MPn = w = p once again.
An increase in any other input will increase the marginal products of all other inputs. This means that more can be produced with the same level of other inputs. The production function twists up and the slope of the production function increases, which in turn implies that the MPnincreases. To see this, consider a Cobb-Douglas production function as in #1,
Y1 = AKa1 Na2 Ea3 Ma4
Y2 = AKa1(N + dN)a2 Ea3 Ma4
MPN = Y2 - Y1 = AKa1 Ea3 Ma4 [(N + dN)a2 - N a2]
For any given dN, the marginal product will increase if A, K, E, or M is increased.
From the text, we can write OKUN's Law as
change in u = - 0.5*[(change in Y / Y) - (change in pot. Y / pot. Y)]
change in u = - 0.5*[3.2 - 2.5] = -0.35
u98 = 8.4% - 0.35% = 8.05%

(1) Guaranteed Income Certificate (GIC)
Interest earned (0.05 x $100,000) = $5,000
Federal tax (0.26 x $5,000) = $1,300
Provincial tax (0.45 x $1,300) = $585
Total tax ($1,300 + $585) = $1,885
After tax nominal rate of return
= [($5,000 - $1,885) / $100,000] x 100 = 3.115 %
After tax real rate of return
= 3.115% - 2.00% = 1.115%
(2) Blue-chip stock
Dividend income (0.045 x $100,000) = $4,500
Taxable amount of dividend (1.25 x $4,500) = $5,625
Gross federal tax (0.26 x $5,625) = $1,462.50
Federal dividend tax credit (0.1333 x $5,625) = $749.81
Total (net) federal tax ($1,462.50 - $749.81) = $712.69
Provincial tax (0.45 x $712.69) = $320.71
Total tax payable ($712.69 + $320.71) = $1033.40
After tax nominal rate of return
= [($4,500 - $1033.40)/$100,000] x 100 = 3.4666%
After tax real rate of return
= 3.4666% - 2.00% = 1.4666%
(3) Growth stock
Capital gain = $4,500
Taxable amount of capital gain (0.75 x $4,500) = $3,375
Federal tax (0.26 x $3,375) = $877.50
Provincial tax (0.45 x $877.50) = $394.88
Total tax ($877.50 + $394.88) = $1,272.38
After tax nominal rate of return
= [($4,500 - $1,272.38)/$100,000] x 100 = 3.2276%
After tax real rate of return
= 3.2276% - 2.00% = 1.2276%
Therefore, Blue-chip stock has highest after tax real rate of return.
The demand for capital is defined by the MPK curve which slopes down. The lower user cost is associated with a larger quantity demanded. This is odd. A firm that requires 50 vehicles will now use 55 to produce the same level of output? Perhaps they can reduce the size of the repair shop and increase the number of people on the road. Note that there may be measurement problem here: the quality problem seen earlier. If the quality change is reflected in the price then the the price of the cars would rise. The user cost may rise or fall. More information is required to give a definitive answer on quantity demanded.
