1. Firms in the same industry always compete in the same
market.
2. The boundaries of a market are determined by product
substitutability and geographic considerations.
3. There can be significant disagreement and dispute about
the actual boundaries of a market.
4. Pure competition is the market structure where a large
number of firms sell identical products.
5. In pure competition, the market demand curve and the
demand curve for an individual seller's product are both
downward sloping.
6. In the long run, a firm in pure competition earns an
economic profit and operates at the minimum point on its
long-run average total cost curve.
7. Purely competitive sellers can earn economic profit over
both the short run and the long run.
8. The demand curve for each individual seller's product in
a monopolistically competitive market is a horizontal line at
the going market price.
9. Product differentiation in a monopolistically competitive
market may allow the seller to raise its price and not lose
all of its buyers.
10. Advertising by sellers in a monopolistically competitive
market that emphasizes the differences between their
products may benefit the consumer by providing
information on product availability and attributes.
11. Firms in monopolistically competitive markets can earn
excess profits over the short run and the long run.
12. Oligopolists are like monopolistic competitors in that
both are price takers.
13. A cartel occurs when several sellers formally join
together and act like a single-firm monopoly.
14. The individual seller's demand curve is the market demand
curve in monopoly.
15. There is no reason for a monopolist to advertise because
it has no competitors.
16. Over the long run, buyers fare better in terms of prices
when facing oligopolists than when facing sellers in any other
market structure.
17. A firm trying to maximize its profit or minimize its loss
from producing should operate where marginal revenue
exceeds marginal cost by the greatest amount.
18. An individual purely competitive seller's marginal revenue
curve is identical to the demand curve for its product.
19. A seller whose price is less than average total cost but
greater than average variable cost will minimize its loss by
producing rather than by shutting down.
20. The marginal revenue curve and the demand curve for a
seller's product are the same when the demand curve for its
product is downward sloping.
