How to discard non-sanitation and free-disposal with paper money

Article Abstract:

A solution to the non-existence of competitive equilibria in an economy where satiation is possible is presented. Based on an economic situation with many agents and where paper money is one of the commodities without transaction costs, it is concluded that competitive equilibrium may exist by using money as a net positive supply even if preferences may be satiated when the agents are permitted to select a consumption set within a given budget.
