Suppose firm A and firm B produce differentiated goods. The inverse demand curve for firm A is pA =20-qA -qB. The inverse demand curve for firm B is pB =20-qA -(7+1) qB. The cost functions of the two firms are the same: Cb =5Qb and Ca= 5 Qb 1.Calculate the best response functions for each firm in a Nash- Cournot equilibrium and illustrate them in a diagram. 2.
