Suppose that Tommy Hilfiger's marginal cost of a jacket is $200 and at one of the firm's shops, total fixed cost is $500 a day. The profit maximizing number of jackets sold in this
shop is 30 a day. Then the shops nearby from other retailers start advertising their jackets. The Tommy Hilfiger shop decides to spend $1,000 a day advertising its jackets, and its
profit maximizing number of jackets sold jumps to 60 a day.
Before advertising: Suppose that the price elasticity of demand is 2. Can you compute the price of a Tommy Hilfiger jacket? And the markup? Please, compute the amount of
maximal profits.

Iyana's profit is maximized when they produce a total of is $ , an amount rompers. At this quantity, the marginal cost of the final romper they produce than the price received for each romper they sell. At this point, the marginal cost of producing one more romper (the first romper beyond the profit maximizing quantity) is $ , an amount than the price received for each romper they sell. Therefore, Iyana's profit-maximizing quantity occurs at the point of intersection between the Because Iyana is a price taker, the previous condition is equivalent to curves.arrow_forwardSuppose 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 Search In the short run, Tommy's economic profit ** A. is unknown, zero OB. decreases with advertising, zero OC. increases with advertising, positive OD. is unknown, positive In the long-run, Tommy's economic profit is Nextarrow_forward

When he does this, the marginal cost of the last shirt he produces is $ , which is than the price Darnell receives for each shirt he sells. The marginal cost of producing an additional shirt (that is, one more shirt than would maximize his profit) is $ , which is than the price Darnell receives for each shirt he sells. Therefore, Darnell's profit- maximizing quantity corresponds to the intersection of the curves. Because Darnell is a price taker, this last condition can also be written asarrow_forward
