An interpretation of unequal exchange from Prebisch-Singer to Emmanuel

Emmanuel's view of the Center-Periphery trade relation is linked to a classical literature in trade and development theory which starts from the work of Prebisch, Singer and Lewis. A very simple general equilibrium Ricardian trade model is formulated to deal with terms of trade determination in the context of class conflict both in the Center and the Periphery. The model focuses attention on the effects of technical progress and changes in income distribution on employment levels in the Periphery, where labor surplus conditions are assumed to prevail.
