Are developing countries catching up?[Aid, growth, and development: have we come full circle]

This paper reviews catch-up growth in various parts of the world, especially in the twentieth century, with a particular focus on what this implies for the Global South. In 1950, US per capita national income, adjusted for purchasing power, was nearly five times the world average. Since then, Western Europe and Japan have closed their per capita income gaps with the USA. East Asia, South Asia and some other developing countries have also started to close their gaps with the West in recent decades. Thus, after well over a century of growing international economic disparities or divergence, the world has witnessed an era of uneven catching up with the North in parts of the South since the mid-twentieth century.
