The Unnatural Death of Natural Monopoly

The old concept in economics of "natural" monopoly refers to an industry where the technological advantages of large-scale production precludes efficient competition among smaller companies.

CHICAGO: The old concept in economics of "natural" monopoly refers to an industry where the technological advantages of large-scale production precludes efficient competition among smaller companies. The alleged superiority of bigness has been used in many, if not most, countries to justify government ownership of many industries because government monopolies are supposed to better look out for the public interest than private monopolies do. Although claims about natural monopoly continue to influence public policies and academic discussions, this concept has become largely irrelevant to the dynamic economies of the modern world.

The growth of global competition implies that even when large scale production is most efficient, companies in small nations are no longer restricted to the inefficiently small scale of their limited domestic market. They can increase production enormously by operating in several nations, as Chilean electric power companies have raised their profits and expanded production out of their small domestic market by operating in other Latin American countries.

A more important defect of the natural monopoly argument is its failure to recognize that new technologies often evolve over time that are efficient at much lower levels of output than older methods of production. For example, small natural gas turbine plants can now generate electricity at lower cost than more traditional and considerably larger coal plants. Cellular phones unencumbered by a wired grid are competing effectively with traditional wired telephone systems, especially in places, such as most of the postcommunist world, where government owned companies are grossly inefficient.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
