A description of mature and catching-up economies: A bottom-up approach from trade specialization data

Using a novel methodology to relate traded products to aggregate country indicators, this paper identifies imported and exported goods that correlate with growth and income per capita, and based upon that, determines the productive and demand structure of mature and catching-up economies. The methodology in question first uses Principal Component Analysis on the products that countries specialize in importing and exporting, to reduce the number of variables that will, later, be linearly related to income and growth using Canonical Correlation Analysis. It is shown that fast growing or catching-up economies are characterized by the export of massproduced manufactured goods, and the import of capital and intermediates - but not consumer goods. Frugality in consumption demand and congruence between exports and imports explain the high growth rates of catchingup or transitioning economies. In contrast, high income and slow growth mature economies are characterized by the export of goods whose production requires advanced technological capabilities. Their demand structure is characterized by the prominence of consumption rather than means of production.
