Clothing retailers have faced greater competition in recent years as more firms have entered the clothing market. Some of the competition has come from foreign competitors, but much of it is domestic competition. As a result there is much competition in markets for many types of clothing and

individual buyers and sellers cannot affect the market price because it is determined by the market forces of demand and supply

The distinguishing of products by brand name, color, and other attributes

is known as product differentiation

. Entry into a monopolistically competitive industry

is relatively easy

Price discrimination is more likely in the case of services than in the case of goods because

it is more difficult to resell services

A monopoly will look for opportunities to price discriminate because the practice

leads to greater profits

many buyers and sellers

marginal cost pricing.

When price and marginal cost are equal for a perfectly competitive firm, the firm is

maximizing economic profit

A market situation in which a large number of firms produce similar but not identical products is

monopolistic competition

Since the firm in the above figure is operating in a monopolistically competitive industry, in the long run we can expect to see

more firms entering the industry until economic profits are zero

moves down its demand curve to a lower price that will increase quantity demand

that both assume many buyers and sellers

Product compatibility is

the capability of a product sold by one firm to function together with another firm's complementary product

A profit-maximizing monopolist earns an economic loss whenever

the demand curve lies completely below the ATC curve.

If a monopolist produces to a point at which marginal revenue is less than marginal cost then

the incremental cost of producing the last unit exceeds the incremental revenue.

The demand for the product of a monopolistically competitive firm is highly elastic when

there are a lot of close substitutes

Firms in a monopolistically competitive market will advertise because

they want to differentiate their products.

. Joe's hotdog stand merges with a company that supplies the condiments to Joe's. This is an example of

For a monopoly earning positive economic profits at the profit-maximizing output level, all of the following are true EXCEPT

P = MR.

Which of the following statements about the elasticity of demand for a monopolist is TRUE?

Since every good has some substitute, even if imperfect, the demand for a good produced by a monopolist will not have zero price elasticity

Which of the following statements is correct about the demand curve of the perfectly competitive industry?

The market demand curve of the perfectly competitive industry is downward sloping while the demand curve facing an individual firm is horizontal

Which of the following is NOT a barrier to entry that would allow a monopolist to keep potential competitors out of its market?

What does it mean when the products sold by the firms in an industry are homogeneous?

The product sold by one firm is a perfect substitute of the product sold by another firm in the same industry.

Which of the following statements is FALSE?

The measurement of industry concentration which calculates the percentage of all sales contributed by a specific number of leading firms is called the

concentration ratio

The demand curve for a perfectly competitive industry is

downward sloping

The most common reason for the existence of oligopolies is

economies of scale

An industry battle between incompatible product formats can occur if competing firms selling compatible products
