Technology and Economic Growth

ROME: The story of Elihu Thompson, the inventor of the electric dynamo, and ultimately a founder of one of America's great companies, General Electric, recurs frequently in the speeches of Alan Greenspan. The chairman of America's Federal Reserve Board is understandably fascinated by the great inventions of the late 19th century which revolutionized industrial production in America and around the globe.

Some may be surprised that a central bank governor is interested in technological innovation, and even more that economists at the Fed are studying the impact of computers on economic growth (their research on this subject, indeed, may be found on the Fed's internet site: Such research may also shed light on whether the current extraordinary expansion of the U.S. economy, which has lasted uninterrupted for the past nine years, is simply a prolonged streak of luck or represents the effect of a new technological revolution, similar to the one which occurred at the end of the 19th century and which is best symbolized by the spread of electric power. The answer to that question not only has important consequences for American monetary policy, but also suggests a few reflections on today's economic conditions in Europe as well as Europe's new single currency.

The reason why the Federal Reserve is studying the electric dynamo is, obviously, not the Fed's interest in history. The story of the diffusion and utilization of the dynamo offers strong analogies with the opportunities and problems posed by today's new information technologies for the organization of enterprises. The first industrial applications of the dynamo began in 1890, but one needed to wait some thirty years before seeing the effects of that then “new technology” on the productivity of enterprises. The most important reason for this delay was the resistance of managers towards adapting the organization of labor in their firms to the new mode of production. Once this transformation took place, however, rapid growth in productivity followed fast.

    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.

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.
