A)
Olivia chooses the
quantities of CDs and DVDs on her budget
line that are on the highest indifference
curve. At this point the budget line is
tangent to the indifference curve. The
highest indifference curve that Olivia can
reach on the budget line shows that so
Olivia buys 5 CDs and 7 DVDs
B) The figure below shows the effect of
rise in the wage page workers who make
CD-Rs. In this case, the price of a factor of
production (labor) used to produce CD-Rs
rises. So the supply of CD-Rs decreases
and the supply curve shifts leftward. As a
result, the equilibrium price rises from P0
to P1 and the equilibrium quantity
decreases from Q0 to Q1.
B) The marginal rate of substitution is the
rate at which Olivia will give up DVDs to
get an additional CD. The marginal rate of
substitution is measured by the magnitude
of the slope of an indifference curve. At
the point where Olivia consumes, the slope
of the indifference curve is the same as
that of the budget line. The slope of the
budget line is -1, so the marginal rate of
substitution is 1.
3.
2. A) The figure below shows the effect of
fall in the price of CD burner. CD burners
and CD-Rs are complementary goods in
consumption. So when the price of a CD
burner falls, the demand for CD-Rs
increases and the demand curve shifts
rightward. As a result, the equilibrium
price rises, from P0 to P1 and the
equilibrium quantity increases from Q0 to
A) GDP = C + I + G + (X - M)
= $120 + $30 + $50 + ($30 - $40) = $190
million.
B) The expenditure approach is used,
which measures GDP as C + I + G + (X M).
