Contestable markets.: In a market an incumbent monopoly faces the following cost curve C(q)=F+cq where F>0 is a fixed cost and c>0 is the marginal cost of production. A potential entrant contests the monopoly. However, due to second mover disadvantage the potential entrant faces a cost curve C(q)=(F+B)+cq where B>0. If the monopoly wants to prevent the entry of a new firm, what price and quantity it needs to sell? Show that this configuration is feasible and sustainable (or at least specify the conditions under which this statement is true).
