a. Determine OS’s profit-maximizing output and price for the accounting
text.
b. A rival publisher has raised the price of its best-selling accounting text
by $15. One option is to exactly match this price hike and so exactly
preserve your level of sales. Do you endorse this price increase?
(Explain briefly why or why not.)
c. To save significantly on fixed costs, Old School plans to contract out
the actual printing of its textbooks to outside vendors. OS expects to
pay a somewhat higher printing cost per book (than in part a) from
the outside vendor (who marks up price above its cost to make a
profit). How would outsourcing affect the output and pricing
decisions in part (a)?


  1. Firm Z is developing a new product. An early introduction (beating rivals
    to market) would greatly enhance the company’s revenues. However, the
    intensive development effort needed to expedite the introduction can
    be very expensive. Suppose total revenues and costs associated with the
    new product’s introduction are given by


where t is the introduction date (in months from now). Some
executives have argued for an expedited introduction date, 12 months
from now (t 12). Do you agree? What introduction date is most
profitable? Explain.


  1. As the exclusive carrier on a local air route, a regional airline must
    determine the number of flights it will provide per week and the fare it
    will charge. Taking into account operating and fuel costs, airport
    charges, and so on, the estimated cost per flight is $2,000. It expects
    to fly full flights (100 passengers), so its marginal cost on a per
    passenger basisis $20. Finally, the airline’s estimated demand curve is
    P  120  .1Q, where P is the fare in dollars and Q is the number of
    passengers per week.
    a. What is the airline’s profit-maximizing fare? How many passengers
    does it carry per week, using how many flights? What is its weekly
    profit?
    b. Suppose the airline is offered $4,000 per week to haul freight
    along the route for a local firm. This will mean replacing one of
    the weekly passenger flights with a freight flight (at the same
    operating cost). Should the airline carry freight for the local firm?
    Explain.

  2. A producer of photocopiers derives profits from two sources: the
    immediate profit it makes on each copier sold and the additional profit
    it gains from servicing its copiers and selling toner and other supplies.
