Let’s Talk Convergence

Homi Kharas's picture

The city of Tianjin In a recent article called “Economic Convergence: The Headwinds Return”, The Economist magazine called the rapid convergence of income levels between developing countries and the United States an aberration. It presented data showing that the difference between income per capita growth in developing countries and in developed countries had peaked around 2008 and had since become steadily smaller. When China is excluded from the calculations, the difference becomes smaller still.

So should we dismiss convergence as a trend whose time is past? I would argue that this would be premature, and that convergence is still a feature of our time. The different conclusion is not because of different data--both of us use the IMF’s World Economic Outlook series for GDP per capita at purchasing power parity terms, and its forecasts until 2019—but a different approach to convergence.
