(a) Mr Blue's expected utility of wealth from gambling is 7.5 while refusing is 8.54. So the gamble makes him less happy.

(b) Miss Red's expected utility of wealth from gambling is 5 and refusing is also 5. So the gamble doesn't affect her happiness at all.

(c) Mr Blue's certainty equivalent of the risky gamble is $25. This is less than his current wealth which is why he would refuse.

(d) Miss Red's certainty equivalent of the risky gamble is any wealth. She's indifferent since she always has the same level of happiness.

(e) Mrs Green's certainty equivalent of the risky gamble is $25. This is less than her current wealth which is why she would refuse.

(e) 10% pa

(a) Prices, ##P_1##.

(b) Gross discrete returns per annum, ##r_{\text{gdr 0 }\rightarrow \text{ 1}} = \dfrac{P_1}{P_0} ##.

(c) Effective annual returns per annum also known as net discrete returns, ##r_{\text{eff 0 }\rightarrow \text{ 1}} = \dfrac{P_1 - P_0}{P_0} = \dfrac{P_1}{P_0}-1##.

(d) Continuously compounded returns per annum, ##r_{\text{cc 0 }\rightarrow \text{ 1}} = \ln \left( \dfrac{P_1}{P_0} \right)##.

(e) Annualised percentage rates compounding per month, ##r_{\text{apr comp monthly 0 }\rightarrow \text{ 1 mth}} = \left( \dfrac{P_1 - P_0}{P_0} \right) \times 12##.

(a) Overnight money market rate.

(b) 2 year government bond yield.

(c) 15 year government bond yield.

(d) Home loan rate.

(e) Small business overdraft rate.

(a) Trade surplus was roughly zero, so Australians exported as much as they imported.

(b) Net Income was negative, so Australians paid more dividends and interest to foreigners than they received. This is probably because Australia has greater gross foreign liabilities than gross foreign assets.

(c) Current account deficit means Australians have to lend to foreigners by buying foreigners’ debt and equity which represent net capital outflows out of Australia.

(d) Net foreign equity liabilities were negative (less than zero) so Australians had positive net foreign equity assets which means that Australians owned more foreign shares than foreigners owned of Australian shares.

(e) Persistent current account deficit will make its net foreign liabilities greater and greater.
