(c) Should firm B go to market 1 if we assume a (Nash) Cournot solution and that firm A will not retaliate entering in market 2?

(e) Consider that in the initial monopoly situation there exists now a national authority (a regulator) that could force the firm to enter in a foreign market if this maximizes welfare. Will we get now different answers for (b) and (c)
