demand function is 1/2 if pi = Pi Q(pi, Pi) = 2/3 if pi Pi Is there a Nash equilibrium (in pure strategies)? If yes, describe it. If not, explain why.Consider a duopoly Bertrand model where two firms simultaneously choose prices p1, p2 E [0, 1] with zero marginal cost. There is a unit demand, and each firm has a capacity constraint of . Assuming efficient rationing rule, firm i's
