Question 298  interest only loan

A prospective home buyer can afford to pay $2,000 per month in mortgage loan repayments. The central bank recently lowered its policy rate by 0.25%, and residential home lenders cut their mortgage loan rates from 4.74% to 4.49%.

How much more can the prospective home buyer borrow now that interest rates are 4.49% rather than 4.74%? Give your answer as a proportional increase over the original amount he could borrow (##V_\text{before}##), so:

###\text{Proportional increase} = \frac{V_\text{after}-V_\text{before}}{V_\text{before}} ###

Assume that:

• Interest rates are expected to be constant over the life of the loan.

• Loans are interest-only and have a life of 30 years.

• Mortgage loan payments are made every month in arrears and all interest rates are given as annualised percentage rates compounding per month.

(a) 0.055679

(b) 0.029631

(c) 0.029547

(d) 0.006245

(e) 0.0025

Question 395  real option, option

The cheapest mobile phones available tend to be those that are 'locked' into a cell phone operator's network. Locked phones can not be used with other cell phone operators' networks.

(a) Destroying customers' expansion option.

(b) Destroying customers' abandonment option.

(c) Destroying customers' timing (or delaying) option.

(d) Destroying customers' production (or switching) option.

Question 489  NPV, IRR, pay back period, DDM

A firm is considering a business project which costs $11m now and is expected to pay a constant $1m at the end of every year forever.

Assume that the initial $11m cost is funded using the firm's existing cash so no new equity or debt will be raised. The cost of capital is 10% pa.

Which of the following statements about net present value (NPV), internal rate of return (IRR) and payback period is NOT correct?

(a) The NPV is negative $1m.

(b) The IRR is 9.09% pa, less than the 10% cost of capital.

(c) The payback period is infinite, the project will never pay itself off.

(d) The project should be rejected.

(e) If the project is accepted then the market value of the firm's assets will fall by $1m.

Question 522  income and capital returns, real and nominal returns and cash flows, inflation, real estate

A residential investment property has an expected nominal total return of 6% pa and nominal capital return of 2.5% pa. Inflation is expected to be 2.5% pa.

All of the above are effective nominal rates and investors believe that they will stay the same in perpetuity.

What are the property's expected real total, capital and income returns?

The answer choices below are given in the same order.

(a) 3.4146%,   3.4146%,   0%.

(b) 3.4146%,   0.4878%,   0.4878%.

(c) 3.4146%,   0%,   3.4146%.

(d) 0.9878%,   0.5%,   0.4878%.

(e) 0.9756%,   0.4878%,   0.4878%.

Question 632  foreign exchange rate, no explanation

Below is a graph of the USD against the JPY and EUR from 1980 to 2015, compiled by the RBA. Select the correct statement about what occurred between 1980 and 2015. Note that in 1980 the euro was around 1.3 USD per EUR and the Yen was around 250 JPY per USD.

(a) The JPY and EUR both appreciated against the USD.

(b) The JPY and EUR both depreciated against the USD.

(c) The JPY appreciated against the USD while the EUR depreciated against the USD.

(d) The JPY depreciated against the USD while the EUR appreciated against the USD.

(e) The JPY and EUR both remained unchanged against the USD.

Question 698  utility, risk aversion, utility function

Mr Blue, Miss Red and Mrs Green are people with different utility functions. Which of the statements about the 3 utility functions is NOT correct?

(a) Neither Miss Red nor Mrs Green would appear rational to an economist.

(b) Mrs Green is satiated when she has $25 of wealth. That is her bliss point.

(c) Mrs Green is risk loving when she has between zero and $25 of wealth, same as Mr Blue.

(d) Mrs Green is risk averse when she has between $25 and $50 of wealth.

Question 723  mean and median returns, return distribution, arithmetic and geometric averages, continuously compounding rate

Here is a table of stock prices and returns. Which of the statements below the table is NOT correct?

Price and Return Population Statistics
Time	Prices	LGDR	GDR	NDR
0	100
1	99	-0.010050	0.990000	-0.010000
2	180.40	0.600057	1.822222	0.822222
3	112.73	0.470181	0.624889	0.375111
Arithmetic average		0.0399	1.1457	0.1457
Arithmetic standard deviation		0.4384	0.5011	0.5011

 

(a) The geometric average of the gross discrete returns (GAGDR) equals 1.04075 which is 104.075%.

(b) ##\exp \left( \text{GAGDR} \right) = \text{AALGDR}##. The natural exponent of the GAGDR equals the arithmetic average of the logarithms of the gross discrete returns (AALGDR).

(c) ##\text{GAGDR}^T = \left( P_T/P_0 \right)##. The GAGDR raised to the power of the number of time period that it's measured over equals the ratio of the first and last prices.

(d) ##\text{GAGDR} = \exp \left( \text{AALGDR} \right)##. This is always true, regardless of the distribution of the prices or returns. The logarithm of the geometric average of the gross discrete returns (LGAGDR) is always equal to the arithmetic average of the logarithm of the gross discrete returns (AALGDR).

(e) ##\text{AAGDR} \approx \exp \left( \text{AALGDR} + \text{SDLGDR}^2/2 \right)##. This is only approximately true and depends on the distribution of the prices and returns. It's asymptotically true as the time period that the returns are measured over reaches infinity.

Question 792  mean and median returns, return distribution, arithmetic and geometric averages, continuously compounding rate, log-normal distribution, confidence interval

A risk manager has identified that their investment fund’s continuously compounded portfolio returns are normally distributed with a mean of 10% pa and a standard deviation of 40% pa. The fund’s portfolio is currently valued at $1 million. Assume that there is no estimation error in the above figures. To simplify your calculations, all answers below use 2.33 as an approximation for the normal inverse cumulative density function at 99%. All answers are rounded to the nearest dollar. Assume one month is 1/12 of a year. Which of the following statements is NOT correct?

(a) The median portfolio value in one year is $1,105,171. In one month it's $1,008,368.

(b) The mean portfolio value in one year is $1,197,217. In one month it's $1,015,113.

(c) The worst one percentile of portfolio values in one year is $435,178.

(d) The worst one percentile of portfolio values in one month is $933,016.

(e) The 98% confidence interval of portfolio values in two years is between $326,918 and $4,563,305.
