PITY THE POOR MALTHUSIANS:

A central aspect of Gordon's thesis is that the conventional measures of economic growth omit some of the largest gains in living standards and therefore underestimate economic progress. A point that is little appreciated is that the standard measures of economic progress do not include gains in health and life expectancy. Nor do they include the impact of revolutionary technological improvements such as the introduction of electricity or telephones or automobiles. Most of the book is devoted to describing many of history's crucial technological revolutions, which in Gordon's view took place in the special century. Moreover, he argues that the innovations of today are much narrower and contribute much less to improvements in living standards than did the innovations of the special century.

Rise and Fall represents the results of a lifetime of research by one of America's leading macroeconomists. Gordon absorbed the current thinking on economic growth as a graduate student at MIT from 1964 to 1967 (where we were classmates), studying the cutting-edge theories and empirical work of such brilliant economists as Paul Samuelson, Robert Solow, Dale Jorgenson, and Zvi Griliches. He soon settled in at Northwestern University, where his research increasingly focused on long-term growth trends and problems of measuring real income and output.

Gordon's book is both physically and intellectually weighty. While handsomely produced, at nearly eight hundred pages it weighs as much as a small dog. I found the Kindle version more convenient. Here is a guide to the principal points.

The first chapter summarizes the major arguments succinctly and should be studied carefully. Here is the basic thesis:

The century of revolution in the United States after the Civil War was economic, not political, freeing households from an unremitting daily grind of painful manual labor, household drudgery, darkness, isolation, and early death. Only one hundred years later, daily life had changed beyond recognition. Manual outdoor jobs were replaced by work in air-conditioned environments, housework was increasingly performed by electric appliances, darkness was replaced by light, and isolation was replaced not just by travel, but also by color television images bringing the world into the living room.... The economic revolution of 1870 to 1970 was unique in human history, unrepeatable because so many of its achievements could happen only once.

The series of "only once" economic revolutions behind this short summary makes up the next fourteen chapters of the book. Most of the innovations are familiar, but Gordon tells their histories vividly. More important, in many cases, he explains quantitatively the way these economic revolutions boosted the living standards of the statistically average American. Among the most illuminating chapters are those on housing, transportation, health, and computers.

The last two chapters are about the fall in Rise and Fall. This book differs from the Spenglerian "decline of the West" genre in an important respect. As the mathematicians might say, Gordon moves up a derivative. In other words, he is not predicting that living standards in the US will decline; rather he views it as likely that the growth rate of living standards will decline from its very rapid pace in the special century.

Gordon sees two sources for his pessimistic outlook. The first is that the long list of "only once" social and economic changes cannot be repeated. A second source is what he calls "headwinds." These are structural changes in the economy that reduce actual output below the country's technological potential and provide another reason for slow growth in living standards in the decades ahead.
