The Chinese Century
By Joseph Stiglitz – January 2015
Without fanfare—indeed, with some misgivings about its new status—China has just overtaken the United States as the world’s largest economy. This is, and should be, a wake-up call—but not the kind most Americans might imagine.
When the history of 2014 is written, it will take note of a large fact that has received little attention: 2014 was the last year in which the United States could claim to be the world’s largest economic power. China enters 2015 in the top position, where it will likely remain for a very long time, if not forever. In doing so, it returns to the position it held through most of human history.
Comparing the gross domestic product of different economies is very difficult. Technical committees come up with estimates, based on the best judgments possible, of what are called “purchasing-power parities,” which enable the comparison of incomes in various countries. These shouldn’t be taken as precise numbers, but they do provide a good basis for assessing the relative size of different economies. Early in 2014, the body that conducts these international assessments—the World Bank’s International Comparison Program—came out with new numbers. (The complexity of the task is such that there have been only three reports in 20 years.) The latest assessment, released last spring, was more contentious and, in some ways, more momentous than those in previous years. It was more contentious precisely because it was more momentous: the new numbers showed that China would become the world’s largest economy far sooner than anyone had expected—it was on track to do so before the end of 2014.
