Question



in long-run equilibrium, both prefectly compeitve and monopolistcally competitve markets achieve a tangecy between the firm's dd demand curve and its average cost curve , figure 10-4 showes the tengency for a monopolistic compeetitor, while figure 10-10 displays the tegency for a perfect competitor . discuss the similarities and differences in the two situations with respect to :


B. the extent of divergence between price and marginal cost

Explanation / Answer

In a perfectly competitive market, each firm individually faces a horizontal demand curve where Price (P)=Marginal Revenue (MR). So in choosing a production quantity where MR=Marginal Cost (MC), the firm prices where P=MR=MC. In a monopolistically competitive market each firm faces a downward sloping demand curve, where P>MR. So in choosing a production quantity where MR=MC, he prices above marginal revenue and marginal cost.
