Abstract

We discuss conditions under which a convex cone \KRΩ\K\subset \R^{\Omega} admits a probability mm such that supk\Km(k)0\sup_{k\in \K} m(k)\leq0. Based on these, we also characterize linear functionals that admit the representation as finitely additive expectations. A version of Riesz decomposition based on this property is obtained as well as a characterisation of positive functionals on the space of integrable functions
