The market demand for a pair of duopolists is given as P=72-Q, where Q = Q1+Q2. Total costs equal 24Q (MC=$24/unit) for each firm. For the following models, determine the equilibrium price, each firm's output, and profit:
a. Shared Monopoly
b. Cournot Duopolists (each rival assumes output is fixed)
c. Bertrand Duopolists (Competitive case)
d. Stackelberg Duopolists (assume firm one is the leader)
