A switchover of global growth engines is taking place. Developing economies as a whole are now the source of more than half of global GDP growth. As a result, concern has naturally shifted to a new question: Are there risks that some or many of these developing countries could fall prey to the "middle-income trap"?
The "middle-income trap" has captured many developing countries: they succeeded in evolving from low per capita income levels, but then appeared to stall, losing momentum along the route toward the higher income levels of advanced economies. Such a trap may well characterize the experience of most of Latin America since the 1980s, and in recent years, middle-income countries elsewhere have expressed fears that they could follow a similar path.
Does moving up the income ladder get harder the higher one climbs?
