2 Stackelberg Suppose econ and man. econ are competing following the rules of the Stackelberg Oligopoly Model. Suppose man. econ is the leader and econ is the follower. Market demand for an economics degree now is () = 10000 2p. Both departments' marginal cost is now $4400 per degree. 2.1 What is the econ department's best response function? 2.2 What is the man. econ department's residual demand curve? 2.3 What is the Nash-Stackelberg equilibrium in this market? 2.4 'What is the price at this equilibrium? 2.5 What are profits for the two departments at this equilibrium? 2.6 Graph the marginal cost, demand, residual demand, and marginal revenue curve for the man. econ department. Show the equi- librium price and quantity for the man. econ department
