Question 180  equivalent annual cash flow, inflation, real and nominal returns and cash flows

Details of two different types of light bulbs are given below:

• Low-energy light bulbs cost $3.50, have a life of nine years, and use about $1.60 of electricity a year, paid at the end of each year.
• Conventional light bulbs cost only $0.50, but last only about a year and use about $6.60 of energy a year, paid at the end of each year.

The real discount rate is 5%, given as an effective annual rate. Assume that all cash flows are real. The inflation rate is 3% given as an effective annual rate.

Find the Equivalent Annual Cost (EAC) of the low-energy and conventional light bulbs. The below choices are listed in that order.

(a) 1.4873, 6.7857

(b) 1.6525, 6.7857

(c) 2.1415, 7.1250

(d) 14.8725, 6.7857

(e) 2.0924, 7.1250

Question 201  DDM, income and capital returns

The following is the Dividend Discount Model (DDM) used to price stocks:

###P_0=\dfrac{C_1}{r-g}###

If the assumptions of the DDM hold and the stock is fairly priced, which one of the following statements is NOT correct? The long term expected:

(a) Dividend growth rate is equal to the long term expected growth rate of the stock price.

(b) Dividend growth rate is equal to the long term expected capital return of the stock.

(c) Dividend growth rate is equal to the long term expected dividend yield.

(d) Total return of the stock is equal to its long term required return.

(e) Total return of the stock is equal to the company's long term cost of equity.

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 384  option, real option

Which of the following is the least useful method or model to calculate the value of a real option in a project?

(a) Project value with the option less project value without the option.

(b) No-arbitrage binomial option pricing model.

(c) Risk-neutral binomial option pricing model.

(d) Gordon growth model.

(e) Black-Sholes option pricing model.

Question 400  option, no explanation

A European put option will mature in ##T## years with a strike price of ##K## dollars. The underlying asset has a price of ##S## dollars.

What is an expression for the payoff at maturity ##(f_T)## in dollars from owning (being long) the put option?

(a) ##\max(S_T - K, 0)##.

(b) ##\max(S_T - K, K)##.

(c) ##\max(K-S_T, 0)##.

(d) ##\max(K-S_T, K)##.

(e) ##\min(K-S_T, 0)##.

Question 639  option, option payoff at maturity, no explanation

Which of the below formulas gives the payoff ##(f)## at maturity ##(T)## from being short a put option? Let the underlying asset price at maturity be ##S_T## and the exercise price be ##X_T##.

(a) ##f_{SP,T}=max⁡(S_T-X_T,0)##

(b) ##f_{SP,T}=max⁡(X_T-S_T,0)##

(c) ##f_{SP,T}=-max⁡(S_T-X_T,0)##

(d) ##f_{SP,T}=-max⁡(X_T-S_T,0)##

(e) ##f_{SP,T}=min⁡(X_T-S_T,0)##

Question 701  utility, risk aversion, utility function, gamble

Mr Blue, Miss Red and Mrs Green are people with different utility functions.

Each person has $50 of initial wealth. A coin toss game is offered to each person at a casino where the player can win or lose $50. Each player can flip a coin and if they flip heads, they receive $50. If they flip tails then they will lose $50. Which of the following statements is NOT correct?

(a) Mr Blue's expected utility of wealth from gambling is 7.5 while refusing is 6.25. So the gamble makes him more happy.

(b) Miss Red's expected utility of wealth from gambling is 7.5 and refusing is also 7.5. This is why she is indifferent.

(c) Mr Blue's certainty equivalent of the risky gamble is $70.71. So he would pay to take part in the gamble.

(d) Miss Red's certainty equivalent of the risky gamble is $50.

(e) Mrs Green's certainty equivalent of the risky gamble is $70.71. She would enjoy taking part in the gamble.

Question 744  income and capital returns, real and nominal returns and cash flows, inflation

If someone says "my shares rose by 10% last year", what do you assume that they mean? The effective annual:

(a) Historical nominal total return was 10%.

(b) Historical real total return was 10%.

(c) Expected nominal total return was 10%.

(d) Historical nominal capital return was 10%.

(e) Expected real dividend return was 10%.

Question 797  option, Black-Scholes-Merton option pricing, option delta, no explanation

Which of the following quantities from the Black-Scholes-Merton option pricing formula gives the risk-neutral probability that a European put option will be exercised?

(a) ##N[d_1]##

(b) ##N[d_2]##

(c) ##−N[−d_1]##

(d) ##−N[−d_2]##

(e) ##N[−d_2]##

Question 890  foreign exchange rate, monetary policy, no explanation
