 1. 

Monopolists are price takers.
 

 2. 

The most common source of a barrier to entry into a monopolist's market is that the monopolist owns a key resource necessary for production of that good.
 

 3. 

A monopoly is the sole seller of a product with no close substitutes.
 

 4. 

A natural monopoly is a monopoly that uses its ownership of natural resources as a barrier to entry into its market.
 

 5. 

The demand curve facing a monopolist is the market demand curve for its product.
 

 6. 

For the monopolist, marginal revenue is always less than the price of the good.
 

 7. 

The monopolist chooses the quantity of output at which marginal revenue equals marginal cost and then uses the demand curve to find the price that will induce consumers to buy that quantity.
 

 8. 

The supply curve for a monopolist is always positively sloped.
 

 9. 

A monopolist produces an efficient quantity of output but it is still inefficient because it charges a price that exceeds marginal cost and the resulting profit is a social cost.
 

 10. 

Using regulations to force a natural monopoly to charge a price equal to its marginal cost of production will cause the monopoly to lose money and exit the industry.
 

 11. 

Most economists argue that the most efficient solution to the problem of monopoly is that the monopoly should be publicly owned.
 

 12. 

Price discrimination is only possible if there is no arbitrage.
 

 13. 

Price discrimination can raise economic welfare because output increases beyond that which would result under monopoly pricing.
 

 14. 

Perfect price discrimination is efficient but all of the surplus is received by the consumer.
 

 15. 

Universities are engaging in price discrimination when they charge different levels of tuition to poor and wealthy students.
