  • A generalized family of partial orders is studied, which is semiparametrized by a utility function $ f $ and a distortion function $ g $ , namely, $ (f,g) $ -utility and distorted stochastic dominance ( $ (f,g) $ -UDSD). Such a family is especially suitable for representing a decision maker’s preferences in terms of risk aversion. We characterize the monotonicity of the partial order in the rank-dependent utility model, and the isotonic classes of rank-dependent utility with $ (f,g) $ -UDSD are also established. Inspired by the concept of the congruent utility class, we introduce the definition of the congruent distortion class. The characterization of the congruent utility class or distortion class of $ (f,g) $ -utility and distorted stochastic dominance is investigated. Based on the main results in this paper, we unify some related results in the existing literature. As an application, we propose a general approach to develop a continuum between first-order stochastic dominance and second-order stochastic dominance based on the partial order.
    A new stochastic dominance based on a fixed utility function and a fixed distortion function.
    A generalized family of partial orders is studied, which is semiparametrized by a utility function $ f $ and a distortion function $ g $ , namely, $ (f,g) $ -utility and distorted stochastic dominance ( $ (f,g) $ -UDSD).

We characterize the monotonicity of the partial order in the rank-dependent utility model, and the isotonic classes of rank-dependent utility with $ (f,g) $ -UDSD are also established.

    • We introduce a new generalized class of partial orders that contains some rules of stochastic dominance as its special cases.
    • We investigate the properties and characterizations of the new partial order through the RDU model.
    • The characterization of utility congruency or distortion congruency of the new partial order is presented.
    • We provide a general approach to interpolate first-order stochastic dominance and second-order stochastic dominance based on the new partial order.
