Kando company incurs a $9 per unit cost for product a, which it currently manufactures and sells for $13.50 per unit. instead of manufacturing and selling this product, the company can purchase product b for $5 per unit and sell it for $12 per unit. if it does so, unit sales would remain unchanged and $5 of the $9 per unit costs assigned to product a would be eliminated. 1. prepare incremental cost analysis. should the company continue to manufacture product a or purchase product b for resale? (round your answers to 2 decimal places.)

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.]
