PROBLEM Suppose that Luigi is a monopolistic competitor whose marginal cost of a jacket is $100 and at one of the firmy's shops, total fixed cost is $200 a day. The profit maximizing number of jackets sold in this shop is 20 a day. Then the shops nearby from other retailers start advertising their jackets. The Luigi shop decides to spend $500 a day advertising its jackets, and its profit maximizing number of jackets sold jumps to 50 a day. 1. What is the shop's average total cost of a jacket sold before the advertising begins? 2. What is the shop's average total cost of a jacket sold after advertising? 3. Before advertising: Suppose that the price elasticity of demand is 2. Can you compute the price of a Luigi jacket? Please, compute the amount of maximal profits. 4. After advertising: Suppose that the price elasticity of demand equals 4. Can you compute Luigi's economic profit
