When the international comparison project published its latest estimates of purchasing power parity exchange rates in April there was some consternation. Poor countries became richer overnight, world GDP increased, and global income inequality was revised downwards. Alas, no one stopped being poor. This column digs into the numbers to see if we’ve been consistently underestimating the relative size of poorer economies and overestimating global poverty and inequality.

The GNI is often regarded as the best indicator of a country’s living standards, but it does not record unilateral transfers – most importantly remittances – which are amongst the largest types of income inflows to developing countries. For many developing countries GNDI is significantly larger than GNI, from 3% for India to 75% for Liberia. This column argues that GNDI is preferable, since GNI masks heterogeneity in purchasing power.
