Two transport monopolies in neighboring countries find themselves in competition on a shared market after deregulation. The demand function for transport is given as yD(p) = 8p and the cost functions for the two firms, B and S, are CTB(y) = 1/2y^2 and CTS(y) = 1/4y^2. The firms will determine their optimal production quantities by considering the other's reaction, and the market will reach an equilibrium with certain quantities, price, and profits for each firm.
