His position was contrary to the views of both Marshall (1879, 1923), his former teacher and expert in trade theory, and Eli Heckscher, whose 1919 article has been credited with first stating the factor endowments theory. The principle of comparative advantage assumes full (or at least constant) employment and a price adjustment mechanism sufficient to convert comparative cost differences into absolute money cost differences and bring balanced trade. Keynes rejected the assumption of such an automatic adjustment mechanism, arguing instead that interest rates – not prices – do the adjusting, and that a persistent trade imbalance – not balanced trade – is the likely outcome.
