You deposit money into a bank. Which of the following statements is NOT correct? You:
One year ago you bought a $1,000,000 house partly funded using a mortgage loan. The loan size was $800,000 and the other $200,000 was your wealth or 'equity' in the house asset.
The interest rate on the home loan was 4% pa.
Over the year, the house produced a net rental yield of 2% pa and a capital gain of 2.5% pa.
Assuming that all cash flows (interest payments and net rental payments) were paid and received at the end of the year, and all rates are given as effective annual rates, what was the total return on your wealth over the past year?
Hint: Remember that wealth in this context is your equity (E) in the house asset (V = D+E) which is funded by the loan (D) and your deposit or equity (E).
Question 883 monetary policy, impossible trinity, foreign exchange rate
It’s often thought that the ideal currency or exchange rate regime would:
1. Be fixed against the USD;

However, not all of these characteristics can be achieved. One must be sacrificed. This is the 'impossible trinity'.
Which of the following exchange rate regimes sacrifices convertibility?
