The powerful conclusions on the equivalence of certain Edgeworthian barter processes and the Walrasian price mechanism as presented in the previous chapter bring up questions regarding the causes of these equivalences.

In this chapter we try to unravel some features of these structural requirements. We emphasize that these conditions are social in the sense that these requirements concern the social trade infrastructure in place in the economy.
