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

We prove a coalitional core-Walras equivalence theorem for an asymmetric information exchange economy with a finitely additive measure space of agents, finitely many states of nature, and an infinite dimensional commodity space having the Radon-Nikodym property and whose positive cone has...

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...
