(a) 24*(1.07)^400 = 1.36057*10^13
(b) Shares should not be of companies in the same industry or country, if you want to diversify your
investment in order to reduce idiosyncratic risk.
37. ANS:
(a) If purchasing power parity holds, the real exchange rate is fixed and equal to one.
(b) The supply of loanable funds increases, and the equilibrium real interest rate falls. Because of the
lower interest rate, UK net capital outflow rises. This increase makes the supply of pounds shift to the
right, and the real exchange rate of sterling depreciates.
38. ANS:
(A)
(1) Substitution bias. The CPI ignores the fact that consumers substitute toward goods that have become
relatively less expensive. (2) introduction of new goods. Because the CPI uses a fixed basket of goods, it
does not take into account the increased well-being of consumers created when new goods are introduced.
(3) Unmeasured quality change. Not all quality changes can be measured.
(B)
i. The expected real interest rate was 4 percent.
ii. The actual real interest rate was 1 percent.
iii. Mervin, the banker, lost because he receives less real interest income than he expected. Romeo
and Juliet gain because they pay less real interest income than they expected.

SHORT ANSWER
35. ANS:
(a) 24*(1.07)^400 = 1.36057*10^13
(b) Shares should not be of companies in the same industry or country, if you want to diversify your
investment in order to reduce idiosyncratic risk.

ID: B
36. ANS:
(a) If purchasing power parity holds, the real exchange rate is fixed and equal to one.
(b) The supply of loanable funds increases, and the equilibrium real interest rate falls. Because of the
lower interest rate, UK net capital outflow rises. This increase makes the supply of pounds shift to the
right, and the real exchange rate of sterling depreciates.
37. ANS:
a. £2,000.
b. £2,000.
c. £2,000.
d. £20,000.
e. £11,000.
38. ANS:
(A)
(1) Substitution bias. The CPI ignores the fact that consumers substitute toward goods that have become
relatively less expensive. (2) introduction of new goods. Because the CPI uses a fixed basket of goods, it
does not take into account the increased well-being of consumers created when new goods are introduced.
(3) Unmeasured quality change. Not all quality changes can be measured.
(B)
i. The expected real interest rate was 4 percent.
ii. The actual real interest rate was 1 percent.
iii. Mervin, the banker, lost because he receives less real interest income than he expected. Romeo
and Juliet gain because they pay less real interest income than they expected.

ID: D
36. ANS:
(a) If purchasing power parity holds, the real exchange rate is fixed and equal to one.
(b) The supply of loanable funds increases, and the equilibrium real interest rate falls. Because of the
lower interest rate, UK net capital outflow rises. This increase makes the supply of pounds shift to the
right, and the real exchange rate of sterling depreciates.
37. ANS:
(A)
(1) Substitution bias. The CPI ignores the fact that consumers substitute toward goods that have become
relatively less expensive. (2) introduction of new goods. Because the CPI uses a fixed basket of goods, it
does not take into account the increased well-being of consumers created when new goods are introduced.
(3) Unmeasured quality change. Not all quality changes can be measured.
(B)
i. The expected real interest rate was 4 percent.
ii. The actual real interest rate was 1 percent.
iii. Mervin, the banker, lost because he receives less real interest income than he expected. Romeo
and Juliet gain because they pay less real interest income than they expected.

SHORT ANSWER
35. ANS:
(A)
(1) Substitution bias. The CPI ignores the fact that consumers substitute toward goods that have become
relatively less expensive. (2) introduction of new goods. Because the CPI uses a fixed basket of goods, it
does not take into account the increased well-being of consumers created when new goods are introduced.
(3) Unmeasured quality change. Not all quality changes can be measured.
(B)
i. The expected real interest rate was 4 percent.
ii. The actual real interest rate was 1 percent.
iii. Mervin, the banker, lost because he receives less real interest income than he expected. Romeo
and Juliet gain because they pay less real interest income than they expected.
36. ANS:
(a) 24*(1.07)^400 = 1.36057*10^13
(b) Shares should not be of companies in the same industry or country, if you want to diversify your
investment in order to reduce idiosyncratic risk.
37. ANS:
a. £2,000.
b. £2,000.
c. £2,000.
d. £20,000.
e. £11,000.
38. ANS:
(a) If purchasing power parity holds, the real exchange rate is fixed and equal to one.
(b) The supply of loanable funds increases, and the equilibrium real interest rate falls. Because of the
lower interest rate, UK net capital outflow rises. This increase makes the supply of pounds shift to the
right, and the real exchange rate of sterling depreciates.
