2. Explain the differences between a firm’s (a) market value, (b) enterprise value, and (c) book value. a) Market value, otherwise known as market capitalization, is the current value of the firm’s common equity on the open market. This is the value necessary to buy the entire firm’s equity. b) Enterprise value is the value of all the claims on the firm’s capital structure less cash. This includes the value of equity, preferred stock, debt, and minority interest less cash. This is the value necessary to purchase the entire firm. c) Book value is the value of a firm’s equity based on historical accounting cost. This value is taken from the balance sheet. 3. Given the assumptions below, calculate (a) equity value and (b) enterprise value. Assumptions

a) 50 MM * 20 = 1,000 MM
b) 1,000 + 25 + 250 – 50 +15 = 1,240 MM

...Economics 370 Microeconomic Theory ProblemSet 6 AnswerKey1) Describe the effects on output and welfare if the government regulates a monopoly so that it may not charge a price above p, which lies between the unregulated monopoly price and the optimally regulate price (determined by the intersection of the firm’s marginal cost and the market demand curve).
As usual, the monopoly determines its optimal output on the basis of MR = MC. Here, however, it cannot charge a price in excess of p*. So, for any output less than Q(p*) (where Q(p) is the demand function) its marginal revenue is p*. On the graph below that gives:
pm p* MR
MC
Demand q
m
q
*
2) The inverse demand curve a monopoly faces is p=10Q-1/2. The firm’s cost curve is c(Q) = 10 + 5Q. Find the profit maximizing price and quantity, and economic profit for the monopoly.
Revenue = pQ = Q(10Q-1/2) = 10Q1/2 MR = 5Q-1/2 MC = 5 Profit maximization implies MR = MC, so 5Q-1/2 = 5, or Q* = 1; p* = 10. Economic Profit = Revenue – Cost = Q × p – c(Q) = 1(10) – (10 + 5Q) Economic Profit = 10 – 15 = -5. So, the monopoly will not produce at all, and will have a profit of zero.
3) The inverse demand curve a monopoly faces is p = 100 – Q. Find the profit maximizing price and quantity, and economic profit if: a) The total cost curve is c(Q) = 10 + 5Q....

C1.2 (i) There are 1,388 observations in the sample. Tabulating the variable cigs shows that 212 women have cigs > 0.
(ii) The average of cigs is about 2.09, but this includes the 1,176 women who did not smoke. Reporting just the average masks the fact that almost 85 percent of the women did not smoke. It makes more sense to say that the “typical” woman does not smoke during pregnancy; indeed, the median number of cigarettes smoked is zero.
(iii) The average of cigs over the women with cigs > 0 is about 13.7. Of course this is much higher than the average over the entire sample because we are excluding 1,176 zeros.
(iv) The average of fatheduc is about 13.2. There are 196 observations with a missing value for fatheduc, and those observations are necessarily excluded in computing the average.
(v) The average and standard deviation of faminc are about 29.027 and 18.739, respectively, but faminc is measured in thousands of dollars. So, in dollars, the average and standard deviation are $29,027 and $18,739.
C1.3 (i) The largest is 100, the smallest is 0.
(ii) 38 out of 1,823, or about 2.1 percent of the sample.
(iii) 17
(iv) The average of math4 is about 71.9 and the average of read4 is about 60.1. So, at least in 2001, the reading test was harder to pass.

1. Assume a monopolist faces the following market demand: Q = 100 - 2P. The monopolist’s total cost function is TC = 5+8Q2. What is the monopolist’s profit-maximizing level of output and price?
Answer
Step 1. Derive the MR and MC functions.
Since Q = 100 - 2P, P = 50 – (Q/2)
TR=P*Q=(50-1/2Q)Q=50Q-1/2Q2
MR=dTR/dQ=50-Q
MC=dTC/dQ=16Q
Step 2. Set MR=MC and solve for P*, Q*
MR=MC
50-Q=16Q
Q*=2.94 or 3 (rounded)
P*=50-1/2Q*=50-1/2*3=48.5
2. Assume a monopolist faces a market demand curve P = 130 – 2Q, and has the short-run total cost function TC = 350 + 10Q.
(a) What is the profit-maximizing level of output and price? What are profits?
(b) Graph the marginal revenue, marginal cost, and demand curves.
(a) Step 1. Derive the MR and MC functions.
P 130 – 2Q
TR=P*Q=(130 – 2Q)Q=130Q – 2Q2
MR=dTR/dQ=130 – 4Q
MC= dTC/dQ=10
Step 2. Set MR=MC and solve for P*, Q*, and π.
MR=MC
130 – 4Q=10
4Q=120
Q*=30
P*=130 –...

Which project should the firm select? Why?
Project B: Managers should try to maximize their stock’s intrinsic value while also bringing in revenue. The P/E ratio shows the dollar amount investors will pay for $1 of current earnings.
Problem 2
If most investors expect the same cash flows from Companies A and B but are more confident that A’s cash flows will be closer to their expected value, which company should have the higher stock price? Explain.
The primary goal of a corporation should be to maximize its owner’s value. If a manager is to maximize shareholder wealth, he/she must know how that wealth is determined. Fundamentally, shareholder wealth is the number of shares outstanding at times the market price per share. A stock’s price at any given time depends on the cash flows a “marginal” investor expects to receive after buying the stock. With that being said, Company A’s cash flow would increase the stock price and the risk would be minimal. Management’s goal should be to make decisions designed to maximize the stock’s price.

i. There is an increase in the price of coffee.
(a) Increase in Demand for coffee. In general, an increase in price of coffee will engender a concomitant decrease in demand. Also of importance is the amount of this change in demand and the affect on total revenue. These changes (demand and total revenue) will be determined by the price elasticity of demand.
ii. There is an increase in the price of tea, which consumers view as a substitute for coffee.
(a) Increase in the Demand for Coffee. In general, an increase in the price of tea will engender a concomitant increase in the demand for coffee. As a close substitute

production are scarce?
CP2. A downward-sloping production possibilities curve shows that in order to obtain
more of one good (or service), another must be forgone. That is the meaning of
scarcity—the situation where we are forced to choose among alternatives.
