The employment of teaching assistants by major universities can be characterized as a monopsony. Suppose the demand for and supply of TAs can be characterized by the following equations: L = 100,000 – 50w. L =- 10,000 + 75w. (Demand for labor; MV) (Supply of labor; AE) where w is the wage (as monthly salary), and L is the number of TAs hired.

A. If the university takes advantage of its monopsonist position, how many TAs will it hire? What wage will it pay? What are the university's monopsony rents?
B. If, instead, the university was forced to act as a perfect competitor, how many TAs would it hire?
C. Calculate the change in consumers' surplus, the change in producers' surplus, and the deadweight loss when moving from the efficient solution to the monopsony solution.
D. Calculate the Lerner Index of Monopsony Power using two different formulas.

The market price of cheeseburgers in a college town increased recently, and the students in an economics class are debating the cause of the price increase. some students suggest that the price increased because the price of beef, an important ingredient for making cheeseburgers, has increased. other students attribute the increase in the price of cheeseburgers to a recent increase in college student enrollment.1. the first group of students thinks the increase in the price of cheeseburgers is due to the fact that the price of beef, an important ingredient for making cheeseburgers, has increased. (what happened to demand and supply, shift to the right or left)2. the second group of students attributes the increase in the price of cheeseburgers to the increase in college student enrollment. (what happens to demand and supply, shift to the right or left)3. suppose that both of the events you analyzed above are partly responsible for the increase in the price of cheeseburgers. based on your analysis of the explanations offered by the two groups of students, how would you figure out which of the possible causes was the dominant cause of the increase in the price of cheeseburgers? (choose a, b,c, or d)a)if the price increase was small, then the supply shift in the market for cheeseburgers must have been larger than the demand shift.b)if the equilibrium quantity of cheeseburgers decreases, then the demand shift in the market for cheeseburgers must have been larger than the supply shift.c)if the equilibrium quantity of cheeseburgers decreases, then the supply shift in the market for cheeseburgers must have been larger than the demand shift.d)whichever change occurred first must have been the primary cause of the change in the price of cheeseburgers.
