A reduced sloping request contour cannot be tangent to efficiency LAC bend at its minimum. Ergo compared to prime race there is going to be excess capabilities.
About significantly more than drawing qc is the most suitable battle productivity, qp is monopolistic race yields less than price battle and you can qn is actually monopolistic competition output below rate competition.
Centered on Chamberlain, best battle can not be considered as ideal aside to possess monopolistic competition. From inside the monopolistic race on account of down inclining demand curve most useful productivity might be leftover regarding at least LAC.
For as long as discover price race and you can 100 % free admission, the tangency point within company’s consult curve and also the LAC curve do resulted in most readily useful returns no way too much capacity. It truly is price of product distinction.
They actions this new monopoly as price of a beneficial excess in order to its marginal pricing. To possess finest battle P = MC for this reason Lerner’s index is actually 0.
In case there are dominance H was step one

Ergo monopoly strength is seen as the inverse regarding price elasticity regarding consult (Ep)
In the event the you can find multitude of companies next Au moment ou was smaller than average ergo H, in the event that you will find faster level of companies then Au moment ou could well be large and therefore H.
