18 1 Security Brokers Inc Specializes In Underwriting New Issues By Small Firms On 2325281

/in /by

(18-1) Security Brokers Inc. specializes in underwriting new issues by small firms. On a recent offering of Beedles Inc., the terms were as follows:

Price to public $5 per share

Number of shares 3 million

Proceeds to Beedles $14,000,000

The out-of-pocket expenses incurred by Security Brokers in the design and distribution of the issue were $300,000. What profit or loss would Security Brokers incur if the issue were sold to the public at the following average price?

a. $5 per share

b. $6 per share

c. $4 per share

(18-2) The Beranek Company, whose stock price is now $25, needs to raise $20 million in common stock. Underwriters have informed the firm’s management that they must price the new issue to the public at $22 per share because of signaling effects. The underwriters’compensation will be 5% of the issue price, so Beranek will net $20.90 per share. The firm will also incur expenses in the amount of $150,000. How many shares must the firm sell to net $20 million after underwriting and flotation expenses?

Hastings Corporation is interested in acquiring Vandell Corporation. Vandell has 1 million shares outstanding and a target capital structure consisting of 30% debt. Vandell’s debt interest rate is 8%. Assume that the risk-free rate of interest is 5% and the market risk premium is 6%. Both Vandell and Hastings face a 40% tax rate.

(22-1) Vandell’s free cash flow (FCF0) is $2 million per year and is expected to grow at a constant rate of 5% a year; its beta is 1.4. What is the value of Vandell’s operations? If Vandell has $10.82 million in debt, what is the current value of Vandell’s stock?Hint:Use the corporate valuation model.

(22-2) Hastings estimates that if it acquires Vandell, interest payments will be $1.5 million per year for 3 years, after which the current target capital structure of 30% debt will be maintained. Interest in the fourth year will be $1.472 million, after which interest and the tax shield will grow at 5%. Synergies will cause the free cash flows to be $2.5 million, $2.9 million, $3.4 million, and $3.57 million in Years 1 through 4, respectively, after which the free cash flows will grow at a 5% rate. What is the unlevered value of Vandell, and what is the value of its tax shields? What is the per share value of Vandell to Hastings Corporation? Assume that Vandell now has $10.82 million in debt.

(24-1) The trustee’s costs total $281,250, and the firm has no accrued taxes or wages. The debentures are subordinated only to the notes payable. If the firm goes bankrupt and liquidates, how much will each class of investors receive if a total of $2.5 million is received from sale of the assets?

Southwestern Wear Inc. has the following balance sheet:

Current assets $1,875,000 Accounts payable $ 375,000

Fixed assets 1,875,000 Notes payable 750,000

Subordinated debentures 750,000

Total debt $1,875,000

Common equity 1,875,000

Total assets $3,750,000 Total liabilities and equity $3,750,000

2 Consider The Ppc For The U S Economy For Civilian Goods And Services Such As Food 2856998

/in /by

Economics 2 Professor Christina Romer
Spring 2019 Professor David Romer
PROBLEM SET 1
DUE AT THE BEGINNING OF LECTURE ON TUESDAY, FEBRUARY 5TH
You may work together on the problems, but your answers must be in your own words and
handwritten. You also must list the other students with whom you worked.
For all questions be sure to explain your answers and to use graphs whenever appropriate.
1. This problem asks about opportunity costs in various situations.
a. It is the night before a statistics exam. You are dividing your time between studying
for the exam and reading comic books. Each hour of studying will raise your score by
2 points, and reading a comic book takes 30 minutes. What is the opportunity cost of
reading a comic book?
b. A piece of jewelry that you can order online costs $200. What is the opportunity cost
of the piece of jewelry?
c. You are in charge of dinner for you and your roommates. You can either buy the
ingredients and make the meal from scratch, which would cost $10 and take 2 hours,
or you can order the meal, which would cost $30 and take 2 minutes. Why would an
economist say that the cost of the meal is not necessarily higher if you order it? Is the
cost necessarily higher if you would use the time you would save in a pure leisure
activity, such as playing video games?
2. Consider the PPC for the U.S. economy for civilian goods and services (such as food,
education, and entertainment) and military goods and services (such as weapons). Both types of
output are produced using capital (machines) and labor.
a. Draw the production possibilities curve (PPC) for the U.S. economy based on this
categorization, with military goods and services on the horizontal axis and civilian
goods and services on the vertical axis. Explain in words what the following
represent: the point where the PPC intersects the vertical axis; the point where the
PPC intersects the horizontal axis; the slope of the PPC at a given point. Why is the
PPC for the U.S. economy likely to be bowed out?
b. Suppose that the aging of the population means that fewer people are available to
work. How, if at all, would this development show up in the PPC diagram?
c. Suppose there is technological change that improves our ability to produce civilian
output, but has no effect on the productivity of capital and labor in producing
military output. How, if at all, would this development show up in the PPC diagram?
d. Suppose that an attack from outer space has two effects: it destroys many factories
(making both military and civilian goods), and it causes us to shift our production so
that the total production of military goods and services is higher than before the
attack. How would this show up (if at all) in the PPC diagram?
3. Three friends, Giovanni, Luisa, and Maria, run a bakery in Rome. The bakery sells two items,
biscotti and cannoli. Each worker works 6 hours per day. While all three can produce both item,
they differ in the number of each they can produce in an hour. The following table shows the
number of biscotti or cannoli each worker could produce in an hour.
Biscotti/Hour Cannoli/Hour
Giovanni 80 20
Luisa 30 50
Maria 40 30
a. For each worker, what is the opportunity cost of 1 biscotto (in terms of cannoli)? Of 1
cannolo (in terms of biscotti)?
b. Draw the production possibilities curve (PPC), with cannoli on the horizontal axis,
for the bakery (for a single day) when there is no specialization—that is, when each
worker divides their time between biscotti production and cannoli production in the
same way as the other two workers. Identify and explain the vertical intercept, the
slope, and the horizontal intercept of the PPC in this case. Why does the PPC without
specialization have the shape that it does?
c. Draw the PPC for the bakery when the three workers specialize according to
comparative advantage. Again, identify and explain the vertical intercept, the
slope(s), and the horizontal intercept of the PPC in this case. Also, give the quantities
of cannoli and biscotti that correspond to any kinks in the PPC. Why does the PPC
with specialization have the shape that it does?
4. Describe and show on a separate graph how each of the following developments would affect
the market price and quantity of chocolate chip cookies.
a. The end of conflicts in major cocoa-producing regions lowers the costs of producing
cocoa, and so causes the price of cocoa (a major ingredient in chocolate) to fall.
b. Improvements in dairy farming lead the price of milk (which many people enjoy
having with chocolate chip cookies) to fall.
c. In an effort to improve health, the government imposes a tax on chocolate chip
cookies of 25 cents per cookie.
d. New studies suggest that chocolate has health benefits, and, at the same time, a
drought in the Midwest causes the price of wheat (a major ingredient in flour) to rise.
5. Consider the market for child car safety seats.
a. Do you think the price elasticity of demand for safety seats is likely to be fairly high
or fairly low?
b. Suppose new discoveries cause the amounts of metal, plastic, and other inputs
needed to produce a safety seat to fall. How would you expect this to affect the
market price and quantity of safety seats? What would you expect to happen to total
spending on safety seats?
c. Suppose many states pass laws increasing the maximum age at which children are
required to be in safety seats. How would you expect this to affect the market price
and quantity of safety seats? What would you expect to happen to total spending on
safety seats?
d. Suppose the government imposes a binding price ceiling on safety seats. How would
you expect this to affect the market price and quantity of safety seats? Will there be a
shortage or a surplus of safety seats? What would you expect to happen to total
spending on safety seats?
