You are the new investment manager of Michael and Ariel. You
received from the previous investment manager of Michael and
Ariel’s partial information regarding their portfolios:
- Both have an optimal portfolio.
- The expected return in Michael’s portfolio is 6%.
- The SD in Ariel’s portfolio is 12%.
You know that the current risk-free interest rate is 5% and the
market portfolio has an expected return of 8% and a SD of
10%.
a. What is the proportion of each brother’s investment in a
risk-free asset out of their portfolio?
b. Is it possible to rank the brothers’ risk preference? Explain.
c. What is the beta in each brother’s portfolio?
d. Suppose that today Michael and Ariel received an offer to buy a share with an expected return of 6% and beta of 0.3. Will they accept the offer?

We are interested in testing the null hypothesis H0:p1=0.5,p2=0.2,p3=0.3, against the alternative hypothesis HA:Atleastoneproportionisincorrect.
a) What is the value of the test statistic?
Round your response to at least 2 decimal places.
b) What conclusion can be made at the 5% level of significance?
| There is no significant evidence against the null hypothesis, and therefore there is no significant evidence that any of the proportions is not correct. | ||
| There is very strong evidence against the null hypothesis, and therefore it is rejected in favour of the alternative hypothesis that at least one proportion is not correct. |

An insurance portfolio consists of two homogeneous groups of clients; N i, (i = 1 , 2) denotes the number of claims occurred in the ith group in a fixed time period. Assume that the r.v.'s N 1, N 2 are independent and have Poisson distributions, with expected values 200 and 300, respectively.
The amount of an individual claim in the first group is a r.v. equal to either 10 or 20 with respective probabilities 0.3 and 0.7, while the amount of an individual claim in the second group equals 20 or 30 with respective probabilities 0.1 and 0.9.
Let N be the total number of claims, and let S be the total aggregate claim.
is a compound Poisson r.v. that can be written as S = ∑ i = 1 N Y i.

Suppose that
The Elasticity of Imports in the USA in the short Run is 0.5
The Elasticity of Imports in Japan in the short Run is -0.3
The Elasticity of Imports in the USA in the long Run is 1.2
According to the Elasticities approach to the Current Account Balance, if the Exchange Rate goes from Yen=$1/100 to Yen=$1/50 ...
| a) |
The Current Account Balance in the US will deteriorate in the short run, and improve in the long run |
|
| b) |
The Current Account Balance in the US will improve in the short run and in the long run |
|
| c) |
The Current Account Balance in the US will deteriorate in the short run and in the long run |
|
| d) |
The Current Account Balance in the US will deteriorate in the short run, and improve in the long run as long as the elasticity of imports in Japan is strictly more than -0.2 |

Expected return and standard deviation. Use the following information to answer the questions:
a. What is the expected return of each asset?
b. What is the variance and the standard deviation of each asset?
c. What is the expected return of a portfolio with 8% in asset J, 46% in asset K, and 46% in asset L?
d. What is the portfolio's variance and standard deviation using the same asset weights from part (c)?
| State of Economy | Probability of State | Return on Asset J in State | Return on Asset K in State | Return on Asset L in State |
| Boom | 0.28 | 0.05 | 0.22 | 0.3 |
| Growth | 0.39 | 0.05 | 0.12 | 0.23 |

The following three games are scheduled to be played at the
World Curling Championship one morning. The values in parentheses
are the probabilities of each team winning their respective
game.
Game 1: Finland (0.2) vs. Canada (0.8)
Game 2: USA (0.3) vs. Switzerland (0.7)
Game 3: Germany (0.4) vs. Japan (0.6)
(a) The outcome of interest is the set of winners for each of the
three games. List the complete sample space of outcomes and
calculate the probability of each outcome.
(b) Let X be the number of European teams that win their respective games. Find the probability distribution of X.
(c) Find the expected value and variance of X.
(d) If two European teams win their games, what is the probability that Finland is one of them?

4. You are visiting the rainforest, but unfortunately
your insect repellent has run out. As a result, at each second, a
mosquito lands on your neck with probability 0.5. If one lands,
with probability 0.2 it bites you, and with probability 0.8 it
never bothers you, independently of other mosquitoes.
a. What is the expected time between successive mosquito bites?
What is the variance of the time between successive mosquito
bites?
b. In addition, a tick lands on your neck with probability 0.1. If
one lands, with probability 0.7 it bites you, and with probability
0.3, it never bothers you, independently of other ticks and
mosquitoes. Now, what is expected time between successive bug
bites? What is the variance of the time between successive bug
bites?

The Neal company wants to estimate next year's (ROE) under
different financial leverage ratios. Neal's total capital is
$14million, it currently uses only common equity, it has no future
plans to use preferred stock in its capital structure and its
federal-plus-state tax rate is 40%. The CFO has estimated next
years EBIT for three possible states of the world: $4.2 million
with a 0.2 probability, $2.8 million with a 0.5 probability, and
$700,000 with a 0.3 probability . Calculate Neal's expected ROE,
standard deviation, and coefficient of variation for each of the
following debt-to-capital ratios; then evaluate the results:
Debt/capital ratio- interest rate
0%- ----------
10- 9%
50- 11
60- 14
