%X In this paper, a class C of risk measures, which generalizes the class of risk measures for the right-tail
deviation suggested by Wang (1998),  is characterized in terms of dispersive order. If dispersive order does not
hold, unanimous comparisons are still possible by restricting our attention to a subclass of C and then the criterion is the excess wealth order. Sufficient conditions for stochastic equivalence of excess wealth ordered random variables are derived in terms of some particular measures of this subclass.
