A lower inclining consult contour can’t be tangent so you’re able to output LAC curve at the the minimal. Ergo compared to primary battle there will probably always be extreme ability.
In the significantly more than diagram qc is most beneficial race production, qp was monopolistic competition yields below rates battle and qn try monopolistic competition yields not as much as rate battle.
According to Chamberlain, best competition can not be thought to be greatest away having monopolistic race. Inside the monopolistic battle on account of down inclining request bend ideal production might possibly be remaining away from the least LAC.

Established firms will set limit price PL equal to Long run average cost of the potential entrants (LACp). Usually this is set at inelastic part of demand curve that is e<1. At this prices established firms are still earning more than normal profit as prices are more than their Long run average cost (LACc). At limit prices potential firms are just earning normal profits, but if they enters into the market quantity will increase and price will fall below PL potential firms will face losses. Thus PL act as limiting price for potential firms to enter into the market.
