6. Two identical firms that have the cost function C(q) = 4q, where j = {1,2} are competing in a homogenous good market. The two firms make simultaneous decisions on price, and they face industry demand Q(P) = 20 - p. What is the Bertrand-Nash equilibrium profit of each firm? Hints for (b) and (c): Solve for each firm j's output (q;) and use the fact that II, Pjqj - Cj(qj). b. Now, suppose the two firms are deciding whether to set a collusive market price of $6 (this means that they would both charge $6). Solve for their profits under this pricing scheme. a. c. If one of the firms decides to deviate from the collusive scheme and undercut its rival's price by $1, how much profit would it earn?
