Economic researchers at the Institut de Recherches Économiques et Sociales in France indicate that global commodity chains have three different elements: (1) a production element linking parts and commodities in complex production chains; (2) a value element, which focuses on their role as “value chains,” transferring value between and within firms globally; and (3) a monopoly element, reflecting the fact that such commodity chains are controlled by the centralized financial headquarters of monopolistic multinational corporations and garner massive monopoly rents, as theorized by Stephen Hymer in the 1970s.
