“There is an even starker contrast between the two groups of countries when one compares their contributions to growth in global debt versus growth in global GDP. Emerging markets contribute far more to growth in global GDP than to the growth in global public debt. These economies accounted for 14 percent of the increase in global debt levels from 2007 to 2012. In contrast, their contribution to the increase in global GDP over this period was 70 percent. The numbers are equally stark when one examines forecasts for the subsequent five years. From 2012 to 2017, emerging markets are expected to account for about three-fifths of global GDP growth but less than one-fifth of global public debt accumulation. In other words, emerging markets are adding substantially to global GDP, whereas advanced economies are mainly adding to global public debt (see Figure A-3 in the Appendix for details). The U.S. and Japan are certainly heavy hitters when it comes to debt accumulation. These two economies are making a far greater contribution to the rise in global debt than to the rise in global GDP. The U.S. contributed 38 percent of the increase in global debt from 2007 to 2012 and is expected to account for nearly half of the anticipated increase from 2012 to 2017. Its contributions to the increases in global GDP over those two periods are 12 percent and 23 percent, respectively. Japan accounted for 25 percent of the increase in debt from 2007 to 2012 and is expected to add 9 percent from 2012 to 2017, whereas its contributions to the increase in global GDP are far more modest.
