We show that p−3r and r increasing, that is, both being greater for utility v than for u, implies greater downside risk aversion for v, where r is the Arrow–Pratt measure and p is the prudence measure. Moreover, this property is reversible, in that p−3r and r together decreasing implies less downside risk aversion.
