A pension plan is obligated to make disbursements of $8 million, $6 million, and $8 million at the end of each of the next three years, respectively. The interest rate is 10% annually. If the plan wants to fully fund and immunize its position, how much of its portfolio should it allocate to one-year zero-coupon bonds and perpetuities, respectively, if these are the only two assets funding the plan? (Round your answers to 2 decimal places. Omit the "%" sign in your response.) |
| Investment in one-year zero-coupon bonds | % | |
| Investment in perpetuity | % | |

A computer system administrator notices that computers running a particular operating system seem to freeze up more often as the installation of the operating system ages. She measures the time (in minutes) before freeze-up for seven computers one month after installation, and for nine computers seven months after installation. The results are as follows: One month after install: 207.4 233.1 215.9 235.1 225.6 244.4 245.3 Seven months after install: 84.3 53.2 127.3 201.3 174.2 246.2 149.4 156.4 102.3 Let μX represent the population mean for the first month and let μY represent the population mean for the seventh month. Find a 95% confidence interval for the difference μX−μY . Round down the degrees of freedom to the nearest integer and round the answers to three decimal places.

3) A sticky goo oozes mysteriously from the rare wazoo
tree, which grows only on the farm of Wolf Molder, just outside of
Pullman, Washington. This goo, when smeared on the face, results in
a tightening of the skin and the elimination of fine lines. Wolf
bottles the goo at a cost of $2 per bottle and sells it to Donna
Scali at a wholesale price of $w per bottle. Donna sells the goo to
the general public over the Internet under the name “Youth Goo” at
a price of $P per bottle. The retail demand for Youth Goo is given
by P = 60 - .01Q.
(a) Write Donna Scali’s profit as a function of the number of
bottles of Youth Goo she sells over the Internet and the wholesale
price, πD(Q;w).
Write an equation characterizing Donna’s profit-maximizing choice
of output as a function of the wholesale price w.
(b) What is Wolf’s profit as a function of the number of bottles of
Youth Goo he sells to Donna, πW(Q)?
What is Wolf’s profit-maximizing choice of output?
(c) What are the resulting values of the wholesale and retail
prices?
What are profits to Donna and Wolf?
(d) Wolf offers Dana a contract in the form of two-part tariff, a
wholesale price, w, and a fixed fee, F. Calculate the wholesale
price that Wolf charges, the optimal quantity that Donna buys, and
Donna’s optimal price. What should be the range of the fee so that
Donna would accept the offer and Wolf prefers this system?
(e) After a long Internet courtship, Wolf and Donna decide to
become partners in business and in life. After combining their
separate businesses (Youth Goo production and retail distribution,
respectively), they conclude that they could make larger combined
profits by choosing a different level of output. What is their new
profit-maximizing level of output Q** and retail price P**?
What are their new profits?

You are an investor with an investment horizon of one year and a certain degree of risk aversion. Your task is to determine the efficient frontier in the case of two risky securities and one risk-free (T-bill) security and select the optimal portfolio depending on your risk-aversion parameter. You need to do your work on an EXCEL SPREADSHEET!
*Note: select two risky securities and one risk-free (T-bill) security OF YOUR CHOICE.
1- Choose
A well-diversified risky bond B represented by its E(RB) and STDB.
A well-diversified stock fund S represented by its E(RS) and STDS.
A T-bill with one-year maturity represented by RF.
2- Choose a correlation coefficient between B and S.
3- Make simulations on STD and E(R) of a "complete" portfolio
(formed with B and S) by varying the weights allocated on B and
S.
4- Construct and graph the opportunity set (feasible set) for B and
S from your simulations.
5- Compute the weights of the tangent portfolio (T).
6- Compute the STDT and E (RT) of the tangent portfolio (T).
7- Add the T-bill to your portfolio and redo step 3. 8- Repeat step 4 with the T-bill rate.
9- Choose different risk aversion parameters and determine your
optimal weights in T and F and for the implied optimal portfolio
compute the E(R) and STD.
10- Provide a summary of your results
