The recent paper by Gast贸n Nievas and Thomas Piketty, has gained substantial praise as well as criticism in a short period of time. Their empirical endeavor is impressive: the authors compiled and published a large dataset of balance of payments, including traded goods, services, direct transfers, and income from foreign labor and capital assets. This is a gruelling task in itself, and the dataset will certainly provide the foundations for many fruitful studies. For many academic economists, Nievas and Piketty鈥檚 own interpretation of the data constitutes one such great contribution for it puts forward, as the title of their paper suggests, that modern inequalities across regions and countries have their roots in colonial extraction and unequal exchange characterizing international trade until today.
We on the other hand argue that the paper falls behind the state of perception of international inequalities in the Marxist tradition, dependency and structural economics literature. It (1) grasps global inequality as the outcome of a collection of distortions of the capitalist market mechanism rather than as an intrinsic feature of the latter; (2) consequently, proposes structural reforms to alter the power asymmetries in international trade, without an appropriate model of those power relations and why they exist in the first place; (3) lacks an adequate theory of production, value and price to understand the exchange relations at stake; and (4) artificially separates the term unequal exchange from the existing literature on trade inequalities, value transfers, and drain of wealth.
