Summary

This lesson introduces monopolistic competition and explains how product differences allow many firms to compete while giving each firm some control over its own product.

Monopolistic competition is a market structure with many firms, each selling a product that consumers see as distinctive from its competitors. Restaurants, clothing stores, golf-ball brands, and beer producers are examples.

All flashcards

What is monopolistic competition?
A market structure with many firms selling products consumers perceive as differentiated.
What does a firm’s perceived demand curve show?
How much consumers will buy from that firm at different prices, holding other conditions constant.
What is zero economic profit?
Revenue covers explicit costs and the opportunity cost of resources, including owners’ alternatives.
What is productive efficiency?
Producing at the minimum point of the average cost curve.
How can advertising affect a firm’s perceived demand?
It may shift demand right or make demand less elastic by strengthening customer loyalty.

Quiz questions

  1. How does the demand curve of a monopolistic competitor differ from that of a monopolist?Answer: It represents demand for one firm’s product, not the entire market.
  2. How does a monopolistically competitive firm identify its profit-maximizing output?Answer: It chooses the output where marginal revenue equals marginal cost.
  3. When firms in a monopolistically competitive market earn positive economic profit, what tends to happen to an incumbent firm’s demand as rivals enter?Answer: Its demand shifts left as customers gain more alternatives.
  4. What does zero economic profit mean for a firm in long-run equilibrium?Answer: Revenue covers explicit costs and the opportunity cost of its resources.
  5. At a monopolistically competitive firm’s chosen output, what does price exceeding marginal cost indicate?Answer: The firm is allocatively inefficient because price exceeds the cost of the last unit.
