Abstract:
The ongoing pattern of capital flows is quite unusual. Emerging market economies finance US consumers who are living beyond their means. This is clearly a misallocation of world saving that is unsustainable in the long run. The present paper uses the INGENUE 2 worldwide growth model to shape the conjecture of a growth regime for the first half of this century. The engine of growth rests on demographic and technological forces tied up together in a catching-up process involving very large countries. In this process, capital flows substantiate an intergenerational saving transfer to the huge number of people who aspire to get access to Western standard of life. Two scenarios explore the consistency of this prospect: a baseline scenario with relatively conservative hypotheses and a fast-growth scenario in China and India. In both scenarios Western Europe and Japan appear to be structural capital exporters with appreciating real exchange rates. The US progressively saves more and recovers a strong foreign net asset position. No scenario prevents world growth from decelerating with demographic trends.
