Stochastic Dominance and Nonparametric Comparative Revealed Risk Aversion

Heufer, Jan - 2012

It is shown how to test revealed preference data on choices under uncertainty for consistency with first and second order stochastic dominance (FSD or SSD). The axiom derived for SSD is a necessary and sufficient condition for risk aversion. If an investor is risk averse, stochastic dominance...
