Exam 7: The Nature of Industry

The industry elasticity of demand for gadgets is −2,while the elasticity of demand for an individual gadget manufacturer's product is −10.Based on the Rothschild approach to measuring market power,we conclude that:

A host of best-selling books advance the thesis that increases in conglomerate mergers and concentration of U.S.industry are responsible for "obscene profits." Do you agree? Explain,using the Lerner index.

As a general rule of thumb,the U.S.Department of Justice views industries to be highly concentrated if the Herfindahl index is:

Monopolistic competition is characterized by:

The products in a monopolistically competitive industry are:

Suppose that there are two industries,A and B. There are five firms in industry A with sales at $5 million, $2 million, $1 million, $1 million, and $1 million, respectively. There are four firms in industry B with equal sales of $2.5 million for each firm. The four-firm concentration ratio for industry B is:

Which of the following integration types has the potential problem of increasing the firm's market power?

An industry consists of four firms with annual sales of $3,000,$5,000,$4,000,and $6,000.What is the industry's HHI?

An industry consists of six firms with annual sales of $300,$500,$400,$700,$600,and $600.What is the industry's C₄?

Which of the following is NOT considered a measure of firm conduct?

The industry elasticity of demand for gadgets is −2,while the elasticity of demand for an individual gadget manufacturer's product is −2.Based on the Rothschild approach to measuring market power,we conclude that:

Having worked for many of the firms in the petroleum industry,you know that the price elasticity of demand for a representative firm is about −1.25.An industry publication recently reported that the Rothschild index for the petroleum industry is estimated to be 0.88.Based on this information,you know that the price elasticity of demand for the firm you currently work for in the petroleum industry is:

Determine whether integration between the following types of firms would constitute a horizontal,vertical,or conglomerate merger. a.A food company and a drug company. b.A milk producer and a cheese producer. c.A computer chip manufacturer and a silicon producer.

The HHI of a local market is usually _____________ that of national markets.

The concentration and Herfindahl indices computed by the U.S.Bureau of Census must be interpreted with caution because:

An industry consists of three firms with equal annual sales.What is the industry's HHI?

Which of the following kinds of market structure are NOT associated with market power?

Which of the following integration types exploits economies of scope?

Which of the following statements is true?

A Herfindahl index of 10,000 suggests:
