However, Prebisch specifically deals with the economic cycle and highlights to a greater extent than Singer the reasons for the different behaviour of wages in developed and underdeveloped countries, and received much greater recognition for his work, in part because of efforts by industrialized countries like the United States to distance themselves from his work.

Few economists today would agree that an import-substitution stance is the correct response to declining terms of trade. The diverse economic structures created an asymmetry in the mechanism of distribution of the fruits of technical progress, argued Prebisch, Singer, and Arthur Lewis in their individual works published in the s.
