QUESTIONS
Use the money market with the general monetary model and foreign exchange (FX) market to answer the following questions. The questions consider the relationship between the U.K. pound (Ã‚Â£) and the Australian dollar (\$). Let the exchange rate be defined as Australian dollars per pound, E\$/Ã‚Â£. In the U.K., the real income (YÃ‚Â£) is 10.00 trill., the money supply (MÃ‚Â£) is Ã‚Â£50.00 trill., the price level (PÃ‚Â£) is Ã‚Â£10.00, and the nominal interest rate (iÃ‚Â£) is 2.00% per annum. In Australia, the real income (Y\$) is 1.00 trill., the money supply (M\$) is AU\$10.00 trill., the price level (P\$) is AU\$20.00, and the nominal interest rate (i\$) is 2.00% per annum. These two countries have maintained these long-run levels. Note that the uncovered interest parity (UIP) holds all the time, and the purchasing power parity (PPP) holds only in the long-run. The half-life of the deviation from the PPP is 4 years, that is, the deviation from PPP shrinks by 50% in 4 years.
Now, consider time T (today) when the Australian real income falls
by 10% unexpectedly so that the new real income in Australia becomes Y\$ = 0.90 trill. With the new real income, the interest rate in Australia falls to 1% per annum today. With these changes, the exchange rate today becomes 2.2848, (E\$/Ã‚Â£ = 2.2848). Assume that Australia and the U.K. use the floating exchange rate system.
1. Calculate the new long-run price level in Australia, P*\$ (round to 4 decimal places).
2. Calculate the new long-run exchange rate, E*\$/Ã‚Â£ (round to 4 decimal places).

3. Calculate the expected exchange rate 1 year from today (T+1), Ee\$/Ã‚Â£ (round to 4 decimal places).

4. Calculate the real exchange rate today (T), q\$/Ã‚Â£ (round to 4 decimal places).
[2 marks]
5. Based on the half-life of the deviation from PPP, calculate the expected real exchange rate 4 years from today (T+4), qe\$/Ã‚Â£,4 (round to 4 decimal places).
[2 marks]
6. Following the permanent fall of Australian income by 10%, the price level in Australia is expected to go up by 5% in 4 years (Pe\$,4 = 21.00). Calculate the expected exchange rate 4 years from today (T+4), Ee\$/Ã‚Â£,4 (round to 4 decimal places).
