Suppose that Tommy Hilfiger's marginal cost of a jacket is a constant $100 and at one of the firm's shops, total fixed
cost is $2,000 a day.
The profit-maximizing number of jackets sold in this shop is 20 a day.
When the shops nearby start to advertise their jackets, this Tommy Hilfiger shop spends $2,000 a day advertising
its jackets, and its profit-maximizing number of jackets sold jumps to 50 a day.
What happens to Tommy's markup and its economic profit? Why?
Tommy's markup
A. rises, falls, or remains unchanged depending on the effect of advertising on demand
OB. falls because advertising decreases demand
OC. rises because advertising increases demand
OD. does not change because advertising is generally ineffective

A. is unknown, zero

2. A ski resort faces daily demand given by p = a - Q, where a varies from day to day. Over a three-
day period, a takes on the values 80.100, and 120. The marginal cost is zero. The fixed cost for the
three-day period is $2500. If the firm uses dynamic pricing, it changes its price every day to
maximize profit. If it uses non-dynamic pricing, it sets the same price for all three days, assuming that
a takes on its average value of 100 each day. Calculate the consumer surplus and the firm's profit over
the three-day period under each pricing approach.

Explain why a single firm might face downward-sloping demand. Explain why, as Q increases, marginal revenue will decline more quickly than demand. Illustrate this with a sketch. Add marginal cost to your sketch and show the point of profit maximisation. The firm’s demand function is P = 100 - ½Q. Find its marginal revenue function. The firm’s cost function is C = 400 + Q + ¼Q2. Find its marginal cost function. Hence find the firm’s profit-maximising level of production. Now assume the firm is a typical firm in a perfectly competitive market. Explain why Q would be higher. Show in your sketch where there is an efficiency gain over the situation in part (b). Assume an initial equilibrium in which the firm in part (b) is earning excess profits. Explain how this excess profit will be reduced to normal profit, in the long run.
