Dynamic exchange economies with uncertainty are considered where the information is released over infinite time. The strong sequential core of such an economy consists of those consumption streams that can be improved upon by no coalition at no moment of time. Non-emptiness of the strong...

This note provides a new proof of the non-emptiness of the fuzzy core in a pure exchange economy with finitely many agents. The proof is based on the concept of <InlineEquation ID="Equ2"> <EquationSource Format="TEX">$(\Pi, \beta)$</EquationSource> </InlineEquation>-balanced core for games without side payments due to Bonnisseau and Iehlé (2003).
