(6) For each situation, solve for the Cournot-Nash equilibrium (Capacity Constraints) 6a) Suppose Sarah's constant marginal cost is $5 but Joe's is $8. Recall that in a Cournot model, products are homogeneous. So each supplier faces the same aggregate demand function. For the numeric example in the lecture (and this exercise) P(Q) = 20 - 0.1 Q where Q = Qjoe + Qsarah
