Abstract
A recent contribution by Meyer et al. (2009, p. 521) corrected an error of fact
by Hardaker et al. (2004b, p. 253) about the comparison between stochastic
dominance with respect to a function (SDRF) and stochastic efficiency with
respect to a function (SERF). While both methods compare risky prospects for
a bounded range of degrees of risk aversion, SERF, unlike SDRF, also demands
an assumption that a chosen measure of risk aversion is constant over all levels
of outcomes being evaluated. It is argued that it is generally reasonable to make
such an assumption, especially when the form of the utility function and the
bounds on the degree of risk aversion are carefully chosen. Then SERF has the
advantage that it can lead to a smaller efficient set than that identified by
SDRF. SERF also has advantages of ease and transparency in use.
