New price adjustments reshape the world, yet again
Angus Deaton, Bettina Aten 16 July 2014
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.
When the international comparison project (ICP) published its latest estimates of purchasing power parity (PPP) exchange rates in April (World Bank 2014), there was considerable surprise and some consternation. Poor countries became richer overnight, at least relative to the rich countries; expressed in US dollars, world average GDP increased. There was a large downward revision of global income inequality. By some calculations, e.g. Chandy and Kharas (2014) and Dykstra et al.

A better indicator for standard of living: The Gross National Disposable Income

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.
Traditionally, the Gross Domestic Product is the most widely accepted indicator of an economy’s size and performance, although in the last decades many contributions have suggested to adopt alternative tools to measure people’s wellbeing (see Stiglitz, Sen, and Fitoussi 2008).
