The economist most renowned for predicting the New Economy of the 1990s now returns-just as books like The Long Boom and Dow 36,000 are turning the idea of perpetual prosperity into conventional wisdom-to say that the dominating economic event of the next few years is likely to be a deep recession, perhaps even a depression. Michael J. Mandel begins The Coming Internet Depression by explaining why just such a depression is not only possible but increasingly likely. His explanation is based in a comparison of the present period with the 1920s: both saw tremendous growth in GDP that was largely centered on the hypergrowth of a single industry-automobiles in the 1920s, information technology today. When this hypergrowth reverts to a normal growth pattern, as the automobile industry did in 1929, the resulting overcapacity will slow down the entire economy. Mandel addresses three key questions: When will the Internet Depression start? How will we know when it's coming? How bad will it be? Finally, he shows how investors, workers, and businesses can navigate the bad times safely and prosper in the long recovery that will follow.
