(a) Mr Blue is as happy with zero wealth as he is with $1,000. Similarly for Miss Red and Mrs Green.

(b) All of the people would appear irrational to an economist. Though Mr Blue appears to be rational when he has more than $192 in wealth.

(c) Mr Blue is risk averse. Miss Red is risk neutral. Mrs Green is risk loving.

(d) Miss Red is totally indifferent to how much wealth she has. She doesn't care about gaining or losing money.

(e) Mr Blue prefers more to less up to a wealth of around $192. At about $192 he is the happiest he can be. This is his bliss point. With more than $192 he becomes less happy.

(a) The returns ##r_\text{t monthly}## are continuously compounded monthly returns and are likely to be normally distributed, so the mean, median and mode of these continuously compounded returns are all equal to 1% per month.

(b) The annualised average continuously compounded return is ##\bar{r}_\text{cc annual}=12×0.01=0.1=12\%\text{ pa}##. The annualised standard deviation is ##\sigma_\text{annual} = \sqrt{12}×0.05=0.173205081=17.32\%\text{ pa}##.

(c) Over the next 10 years the mean, median and mode continuously compounded 10 year returns will all equal ##0.01 \times 12 \times 10 = 120\%##.

(d) Over the next 10 years the expected mean gross discrete 10 year return is ##e^{(0.01 - 0.05^2/2)×12×10} = 2.857651118## and the median gross discrete 10 year return is ##e^{(0.01 + 0.05^2/2)×12×10}=3.857425531##.

(e) If the current price of the CBA shares is $75, then in 10 years they’re expected to have a mean value of ##75×e^{(0.01 + 0.05^2/2)×12×10} = 289.3069148## and a median value of ##75×e^{0.01×12×10}=249.0087692##.

(a) The home loan is a debt liability to the bank.

(b) The bank invested in your debt.

(c) You are indebted to the bank.

(d) You owe the bank principal and interest payments.

(e) You sold your promise to the bank to pay the principal and interest.

(a) Expected total return will equal its required total return if the stock is fairly priced.

(b) Expected total return will be less than its required total return if the stock is over-priced.

(c) Required total return should be higher than the risk free government bond yield if the stock has a positive beta.

(d) Required total return depends on its total variance, required capital return depends on systematic variance and the dividend yield depends on idiosyncratic variance.

(e) Expected capital return equals the expected total return less whatever the management decide that they will pay as an income return (which is the dividend yield).

(a) Coupon-paying, with regular coupon payments prior to maturity.

(b) Discount securities, so price is less than face value if interest rate is positive.

(c) Unsecured.

(d) Short term, their original maturity is usually less than one year.

(e) Priced using simple interest rates.
