191 Reading: Monopoly and Antitrust Policy
MORE THAN COOKING, HEATING, AND COOLING
If you live in the United States, there is a slightly better than 50–50 chance your home is heated and cooled using natural gas. You may even use natural gas for cooking. However, those uses are not the primary uses of natural gas in the U.S. In 2012, according to the U.S. Energy Information Administration, home heating, cooling, and cooking accounted for just 18% of natural gas usage. What accounts for the rest? The greatest uses for natural gas are the generation of electric power (39%) and in industry (30%). Together these three uses for natural gas touch many areas of our lives, so why would there be any opposition to a merger of two natural gas firms? After all, a merger could mean increased efficiencies and reduced costs to people like you and me.
In October 2011, Kinder Morgan and El Paso Corporation, two natural gas firms, announced they were merging. The announcement stated the combined firm would link “nearly every major production region with markets,” cut costs by “eliminating duplication in pipelines and other assets,” and that “the savings could be passed on to consumers.”
The objection? The $21.1 billion deal would give Kinder Morgan control of more than 80,000 miles of pipeline, making the new firm the third largest energy producer in North America. As the third largest energy producer, policymakers and the public wondered whether the cost savings really would be passed on to consumers, or would the merger give Kinder Morgan a strong oligopoly position in the natural gas marketplace?
That brings us to the central question this module poses: What should the balance be between corporate size and a larger number of competitors in a marketplace? We will also consider what role the government should play in this balancing act.
Introduction to Monopoly and Antitrust Policy
The previous modules on the theory of the firm identified three important lessons: First, that competition, by providing consumers with lower prices and a variety of innovative products, is a good thing; second, that large-scale production can dramatically lower average costs; and third, that markets in the real world are rarely perfectly competitive. As a consequence, government policymakers must determine how much to intervene to balance the potential benefits of large-scale production against the potential loss of competition that can occur when businesses grow in size, especially through mergers.
For example, in 2006, AT&T and BellSouth, two telecommunications companies, wished to merge into a single firm. In the year before the merger, AT&T was the 121st largest company in the country when ranked by sales, with $44 billion in revenues and 190,000 employees. BellSouth was the 314th largest company in the country, with $21 billion in revenues and 63,000 employees.
The two companies argued that the merger would benefit consumers, who would be able to purchase better telecommunications
