The diagram above represents a monopolistically competitive firm. Answer the questions below. Is this firm operating in the short-run or long-run? How do you know? Calculate this firm’s accounting profit. From the diagram, what is the productively efficient output for this firm? From the diagram, economies of scale are maximized at which output level? Explain. From the diagram, what is the allocatively efficient output for this firm? Explain.
In the long run, the positive economic profits earned by the monopolistic competitor will attract a response either from existing firms in the industry or firms outside. As those firms capture the original firm’s profit, what will happen to the original firm’s profit-maximizing price and output levels? Show on a graph

In long run equilibrium, economic profits tend to zero in a perfectly competitive market and also in a monopolistically competitive market. This is true because both market structures share a crucial characteristic. What is the characteristic that causes economic profits to get pushed towards zero in both perfect competition and monopolistic competition?
