b) be indifferent to the bet if he is risk-neutral.
c) take the bet only if he is risk averse.
d) not take the bet if he is risk averse.

A cosmetics company is conducting a second-year review of one of its newest products.
The marketing department expects that the firm will continue to earn profits from the
sale of the product in the third year as it did in the past two years. Senior management,
however, feels that the profit projections would vary based on other factors such as the
price of the competitor's products, the actual level of sales, and the possibility of cost
reductions. In other words, the senior management is undertaking _____.
a) a sensitivity analysis
b) an enumeration study
c) a benefit-cost analysis
d) a contingent valuation study
e) a strategic analysis
Assume that Insite Corporation produces advanced analytic software for computer
simulations called Model-It. Based on an analysis of product sales over a two-year
period, Insite's marketing department estimates the demand for Model-It to be QM=
1,200 '“ 8PM+ 4PS, where QMdenotes units sold of Model-It software, PMdenotes
Model-It's price, and PSdenotes the price of a best-selling statistical software package
(with both prices in dollars).
(a) Currently, PM= $200 and PS= $300. What is the predicted demand for Model-It
software?
(b) The price PShas been unchanged (at $300) during the last 6 months. Given this
information, derive the equation for Model-It's demand curve (with QMas the left-side
variable). Also determine its inverse demand curve (with PMas the left-side variable).
(c) An industry analyst comments that demand for Model-It is not very sensitive to
changes in the price of the statistical software package PS. (This package does perform
some of the same operations as Model-It, but not as quickly or conveniently.) Carefully
assess this contention. Is his contention correct?
(d) Suppose the marginal cost of producing Model-It is negligible. However, the
company incurred significant costs in developing the product for market (estimated to
be about $350,000). Using Model-It's estimated demand curve, determine the optimal
price and output for Model-It.
With declining probabilities of success, the optimal-stopping strategy is to:

d) discontinue investing when the expected profit is zero.
e) invest once in pursuit of commercial success and then discontinue investing.
Which of the following is true in the long run under monopolistic competition?

(a) Determine the price and output that maximize total revenue, and the level of profit.
(b) Determine the price and output that maximize profit, and the level of profit.
(c) Compare the goals of revenue-maximization versus profit-maximization, and
comment on the appropriate goal of the firm.

maximize profit. Which, among the following, are the decision variables?
a) Profit contributions of shafts and plates
b) Maximum weekly labor hours available
c) Milling and lathe machine hours available per week
d) Quantities of shafts and plates produced per week

Some years ago, Time Warner (TW) and Disney were engaged in lengthy negotiations
to strike a deal so that TW's cable television service would continue to carry Disney
programming and Disney's ABC network channels. Without an agreement, TW would
lose ABC and Disney shows in 3.5 million homes across seven major markets. Disney
was demanding as much as $300 million from TW for the right to carry the channels. It
also wanted TW to feature its new channels (including Toon Disney) and for TW to
make the Disney channel part of its basic cable package. If its demands were not met,
Disney threatened to pull its programming immediately, during the crucial ratings
sweeps period when audience levels are measured and future advertising rates are set.
Losing ABC and Disney would anger TW's cable customers who might decide to
switch to rival satellite television to get the channels. TW wanted the current agreement
extended for six months, by which time the AOL Time Warner merger would be
completed (securing the company's position as a multimedia giant).
(a) Describe the relevant factors that would influence the 'balance of power' in the
negotiation between Disney and TW. Is each side's negotiation strategy utilizing what
power it has? Explain briefly.
(b) Imagine that the negotiations were to end in failure. Provide at least two reasons (in
general) why this kind of outcome could occur.
(c) Disney is worried that in the near future when interactive television is a reality, TW
could hinder Disney and others from offering interactive programming over its cable
lines while favoring its (TW's) own programming. Disney is pressing TW to commit to
treat others' channels and programming the same as their own. TW says Disney's
demand is too broad for discussion and that it is impossible to negotiate the terms of
businesses that don't yet exist. What are the pros and cons of considering these issues in
the current negotiations?
Some years ago, the three leading aluminum producers in the U.S. changed prices nine

c) price discrimination
d) tacit collusion
e) price fixing

d) Full-cost pricing is based on the markup of price over average variable cost.
e) Full-cost pricing takes into account the price elasticity of demand for the product.

Fisherburg is a growing industrial and tourism community with a population of 50,000
and a regional labor force pool of 40,000. A multinational corporation operates an aging
paper producing plant in the community. The plant employs almost 1,500 workers and
there is some concern that the current recession will force the plant to cut back
production. There is even some risk that the plant will close permanently.
During the past year a group of resort owners, riverfront homeowners, and outdoor
sports enthusiasts have formed a committee to address river pollution. Their petition for
placing a '˜clean river' amendment on the ballot in the upcoming local election will soon
be considered by the city council. The council president is concerned about the impact

objective economic evaluation of potential problems the community faces.
The current manager of a small bicycle shop estimates the demand curve for a child's
starter bike to be: P = 80 '“ 2Q. Costs are given by: C = 200 + 20Q. The former owner
of the shop (now retired) urges the manager to keep prices low so as to increase sales
and maximize revenue. (The shop pays the former owner 5% of each dollar of earned
revenue). If current management follows the former owner's goal, what sales output and
price should it set? What strategy would you recommend to maximize profits?
