Risk aversion and insurance are two prominent and interconnected concepts in economics and finance. To explore their fundamental connection, we introduce risk-insurance parity, whi…
Higher-order Gini indices: An axiomatic approach
Xia Han, Ruodu Wang, Qinyu Wu
Via an axiomatic approach, we characterize the family of n-th order Gini deviation, defined as the expected range over n independent draws from a distribution, to quantify joint di…
Prudence and higher-order risk attitudes in the rank-dependent utility model
Ruodu Wang, Qinyu Wu
We obtain a full characterization of consistency with respect to higher-order stochastic dominance within the rank-dependent utility model. Different from the results in the litera…
The reference interval in higher-order stochastic dominance
Ruodu Wang, Qinyu Wu
Given two random variables taking values in a bounded interval, we study whether one dominates the other in higher-order stochastic dominance depends on the reference interval in t…
