Trade in intermediates (or ‘unbundling of production') and trade in capital have become increasingly important in last 25 years. This column shows that trade in intermediates generates a reallocation of capital across countries that exacerbates world inequality in both income and welfare. Unbundling of production hurts middle-income countries but helps those with high productivity. Trade in intermediates also increases within-country inequality, and this increase is U-shaped in the aggregate productivity level of the country.
