The Geopolitical Economy of International Inequality

This article shows that economic inequality between nations has systematically worsened in monetary terms since 1950, and that the principal explanator is inequality between blocs of nations, notably the persistent gap between the Global North and Global South. By 2022, the GDP per capita of the North was 12 times greater than that of the South, this ratio being twice as great as in 1950. This general trend has two consistent exceptions, China and Vietnam. There was also a brief reversal of the trend from 2000 to 2012. However, except for China and Vietnam, it has resumed since then. The article shows that both the Global South and North are coherent entities: they are historically stable and converge internally while diverging from each other. It assesses the implications for international inequality and convergence research and draws out some consequences for world geopolitical relations. Finally, the article sets out the case for an international classification standard that facilitates systematic research into inter‐bloc inequality.
