Andrea Kimball has recently acquired a franchise of a well-known fast-food restaurant chain. She is considering a special promotion for a week during which hamburger prices would be reduced $0.40 from the regular price of $1.09 to $0.69. Local advertising expenses for this special promotion will amount to $4,500. Andrea expects the promotion to increase sales of hamburgers by 20% and French fries by 12%, but she expects the sales of chicken sandwiches to decline by 8% (because some customers, who otherwise may have ordered a chicken sandwich, will order a hamburger instead because of its attractive low price). The following data have been compiled for sales prices, variable costs and weekly sales volumes: Product Sales Price Variable Costs Sales Volume Hamburgers $1.09 $0.51 20,000 Chicken sandwiches 1.29 0.63 10,000 French fries 0.89 0.37 20,000 Evaluate the expected impact of the special promotion on sales and profits. Should Andrea go ahead with this special promotion

Suppose a firm faces a fixed price of output, 푝푝= 1200. the firm hires workers from a union at a daily wage, 푤푤, to produce output according to the production function 푞푞= 2퐸퐸12. there are 225 workers in the union. any union worker who does not work for this firm is guaranteed to find nonunion employment at a wage of $96 per day. a.what is the firm’s labor demand function? b.if the firm is allowed to choose 푤푤, but then the union decides how many workers to provide (up to 225) at that wage, what wage will the firm set? how many workers will the union provide? what is the firm’s output and profit? what is the total income of the 225 union workers? c.now suppose that the union sets the wage, but the firm decides how many workers to hire at that wage (up to 225). what wage will the union set to maximize the total income of all 225 workers? how many workers will the firm hire? what is the firm’s output and profit? what is the total income of the 225 union workers? [hint: to maximize total income of union, take the first order condition with respect to w and set equal to 0.]
