Abstract: We show that under certain general conditions any finitely additive measure which is defined for all subsets of a set $ X$ and is invariant under the action of a group $ G$ acting on $ X$ is concentrated on a $ G$-invariant subset $ Y$ on which the $ G$-action factors to that of an amenable group. The result is then applied to prove a conjecture of $ S$. Wagon about finitely additive measures on spheres.
