FROM THE CLASSICAL ECONOMISTS TO EMPIRICISTS: A REVIEW OF THE TERMS OF TRADE CONTROVERSY

Contrary to the classical position, the works of Prebisch and Singer in the middle of the last century launched the controversial hypothesis of a long-term decline in the terms of trade of primary products vis-á-vis manufactured goods and a corresponding decline in the terms of trade of developing countries vis-á-vis advanced ones. The present study traces the origin and evolution of the hypothesis and reviews the related statistical debate. It also reviews the theoretical support for the Prebisch–Singer hypothesis. It is an exercise in the history of economic thought to trace how the controversies surrounding the terms of trade have evolved over time, specifically noting that, with the development of the field of econometrics, the central thesis of the argument got lost somewhere in the realm of hi-tech statistical debates.
