What are the most important differences between perfectly competitive markets and monopolistically competitive markets? Give two examples of products sold in perfectly competitive markets and two examples of products sold in monopolistically competitive markets.
Monopolistically competitive firms could increase the quantity they produce and potentially lower the average total cost of production. Why don't they do so?
What do economists mean when they say that competitive markets are more efficient than monopolistic markets?
Monopolistic markets result in lower price and higher production
Competitive markets result in lower prices, monopolistic market result in higher production
Competitive markets result in lower costs, lower prices, and higher levels of production

- The following graph represents a monopolistically competitive firm in long-run equilibrium. Place the black point (cross sign) on the graph to indicate the short-run profit-maximizing price and quantity for this monopolistically competitive company. Next, place the grey star on the graph to indicate the point where the LRAC reaches a minimum.

(I have 2 demand curves (sr and lr), but only 1 MR curve (sr). I think it would be to the left of MR sr, but don't know how to draw it. One would need to know this to figure out excess capacity and markup, right?arrow_forwardIn 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.
