Abstract
We derive an explicit formula for a marginalist and efficient value for TU game which
possesses the null-player property and is either continuous or monotonic. We show that
every such a value has to be additive and covariant as well. It follows that the set of all
marginalist, efficient, and monotonic values possessing the null-player property coincides
with the set of random-order values, and thereby the last statement provides an axiom-
atization without the linearity axiom for the latter which is similar to that of Young for
the Shapley value. Another axiomatization without linearity for random-order values is
provided by marginalism, efficiency, monotonicity, and covariance.
