We define the notion of properness in the framework of coalitional economies. Through this, we obtain a core-Walras equivalence theorem for exchange economies with a measure space of agents and an infinite dimensional commodity space, whose positive cone has possibly empty interior

Continuing the investigation on finitely additive economies with infinite dimensional commodity space, we state a core-walras individualistic equivalence for an economy where preferences admit a summable map of extremely desirable commodities. The main result extends previous equivalences...
