Suppose two firms sell a homogeneous product at constant marginal cost, \(M C=2\), in a market. The inverse market demand curve is \(p=50-2 Q\), where \(Q=q_{1}+q_{2}\). What is each firm's market share in a Nash-Cournot equilibrium? If advertising by either or both firms increases the market demand to \(p=62-2 Q\), is the market share of either firm \(\left(q_{1} / Q, q_{2} / Q\right)\) affected?
