Answer #1

Market equilibrium in Bertrand competition is always at a point where price=marginal cost.

P1=P2=marginal cost=c

firms in monopolistic competition doesnot reach perfectly competitive equilibrium because monopolistic competitive firm has marginal revenue less than average revenue whereas in perfect competition marginal revenue=average revenue. And in both market firm produces at a point where MR=MC.

thus in perfect competition, AR=MC and monopolistic competition MR=MC

Firm 1 produces goods 1, and firm 2 produces goods 2, and two market demand functions are given by q1(p1,p2) = 12 - 2p1 +p2 and q2(p1,p2) = 15q22 + 45Q . Furthermore, assume that the two firms have the same cost function such that fixed cost is $20 and variable cost is zero.
