The employment of teaching assistants (TAs) by major universities can be characterized as a monopsony. Suppose the demand for TAs is W=30,000-125 Q, where W is the wage (as an annual salary) and n is the number of TAs hired. The supply of TAs is given by W=1200+75Q, and the marginal expenditure curve is ME=1200+150Q.

Part 2 a. If the university takes advantage of its monopsonist position, how many TAs will it hire? What wage will it pay? (Round your responses to two decimal places.) The university will hire enter your response here TAs at a wage of $ enter your response here per year. Part 3 b. If, instead, the university faced an infinite supply of TAs at the annual wage level of $11,000, how many TAs would it hire? (Round your response to two decimal places.) In this case, the university will hire enter your response here TAs.
