1. Skirts have recently become a big item for the Soleon Department Store. The buyer was able to obtain 3 different styles. Her order is as follows:

If the average markup goal for these 3 skirt styles is 55%, what is the expected total dollar retail for them? (5 points)

Suppose you have complete health insurance. You will use medical care up to the point where:

A) your total benefits equal the costs of providing the medical care.

B) your marginal benefit is zero.

C) your marginal benefit is equal to the marginal cost of the medical care.

D) your marginal benefit is equal to the total costs of providing the medical care.

E) your total benefits are equal to the cost of your health care insurance.

Suppose that you have the following numbers for a firm in a monopolistically competitive industry.

Total Revenue=1200

Marginal Revenue=10

Total Cost=700

Total Variable Cost=500

Price=12

MC=6

Explain how you know that:

a. this firm is not maximizing profit.

b. this firm is operating in the short-run.

c. there is excess capacity or “waste” associated with this firm (Hint: Given the information above, what is ATC? Is the firm operating at the minimum of the ATC curve?)

The market (inverse) demand function for a homogenous good is P(Q) =
10 – Q. There are three firms: firm 1 and 2 each have a total cost of Ci(qi) = 4qi for i ∈ {1.2}. and firm 3 has a total cost of C3(q3) = 2q3. The three firms compete by setting their quantities of production, and the price of the good is determined by a market demand function given the total quantity. Calculate the Nash equilibrium in this game and the corresponding market price.

Consider an industry with n identical firms competing a l´a Cournot. Demand is P(Q) = 1 − Q, and each firm’s total cost function is T C(qi) = cqi . (a) Find the limit of the total equilibrium output Q∗ (n) as n goes to infinity. (b) Suppose that n > 3 and 3 firms decide to merge. The new firm has the same total cost function as its predecessors. What is the condition on n that ensures that the merger is profitable?

CASE STUDY 6.1 IMPORTANT CONSIDERATIONS FOR AN UNDERAGE DRINKING INTERVENTION

Dr. Smith works for a local university, and has been approached by a local health department about a project pertaining to high alcohol consumption among high school students. According to local statistics produced by the health department, 35% of adolescents in the community have never had alcohol and do not plan to have it in the near future, 35% of adolescents have never had alcohol but are planning to try it or are willing to try it in the near future, 25% of adolescents have consumed alcohol at least once in the last 30 days, and 5% of adolescents have consumed alcohol at least 5 times in the last 30 days. The local health department wants to create an intervention to reduce underage drinking in the community but is unsure about what to target, whom to target, and how to implement the program.

Questions for Reflection and Discussion

1. In a comprehensive intervention, which levels of prevention would be relevant?

2. How could the ecological model be used to help identify factors associated with underage drinking? Brainstorm various factors in the ecological model that could be associated with underage drinking.

Exhibit 20-1

You have two metal spheres on insulating stands. You bring them each in turn near the ball of a positively charged electroscope. In each case the deflction of the leaves is reduced slightly. You then bring them each in turn near the ball of a negatively charged electroscope and find that sphere A causes the deflection to increase, whereas sphere B causes it to decrease.

7.Refer to Exhibit 20-1. Sphere A is

a. positively charged.

b. negatively charged.

c. neutral.

d. There is not enough information to determine this.

8.Refer to Exhibit 20-1. Sphere B is

a. positively charged.

b. negatively charged.

c. neutral.

d. There is not enough information to determine this.

9.A metal sphere on an insulating stand has a charge of 16 nC. A second metal sphere, also on an insulating stand, is initially uncharged. The two spheres are briefly touched together. The second sphere is then grounded. After this procedure, the charge on the original sphere is

a. 16 nC

b. 8 nC

c. 4 nC

d. 0 nC

e. more than 16 nC

f. There is not enough information to determine this

A small businessman is planning on opening a new retail location. Three locations are available, and he is interested in the annual income of families near each location. A random sample of 4 families is selected near each location, and the results are shown below (in thousands of dollars). Use this data to test the hypothesis that mean income is the same in all three areas.
