Abstract: Köhler's critique of global wages, where he presents the concept of productivity with great clarity, combines very well with Chaves' presentation of Köhler's model of Unequal Exchange (UE). A brief and solid common position emerges. As I wrote that "the dimension of non-equivalence in a strict, logical sense" can only be shown by comparing real wages, I fully second Köhler's use of Purchase Power Parity (PPP)-data. In the 1980s, I explicitly referred to the research on PPP comparisons. Therefore I am glad he taps the progress made by PPP-research. Nevertheless, Köhler's model does not explain UE.
