In chapter 1, you learned that buying and selling textbooks are two separate decisions made at the margin. textbooks create value both when they are bought and when they are sold. think about your decision to buy the textbook for this course. you paid $225 for the book, but you would have been willing to pay $500 to use the book for the semester. suppose that at the end of the semester you could keep your textbook or sell it back to the bookstore. once you have completed the course, the book is worth only $70 to you. the bookstore will pay you 50% of the original $225. how much total value have you gained?

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.]
