particular industry.

In the natural gas industry, low average total costs are obtained only through large-scale
production. In other words, the initial cost of setting up all the necessary pipes and hoses
makes it risky and, most likely, unprofitable for competitors to enter the market.
In an imaginary country, there is only one federally licensed lottery agency in any state; that
is, it is impossible for any private firm to start up a competitive lottery without a government
license to do so.
Throughout much of the 20th century, many people viewed South Africa's De Beers Group as a
monopoly because it controlled a large percentage of diamond production and sales.
