Answer the following questions either true or false:
(a) If asset A is stochastically dominant over asset B according to the second-order criterion, it is also dominant according to the first-order criterion.
(b) If asset A has a higher mean and higher variance than asset B, it is stochastically dominant, according to the first-order criterion.
(c) A risk-neutral investor will use second-order stochastic dominance as a decision criterion only if the return of the underlying assets are normally distributed.
(d) A second-order stochastic dominance is consistent with utility functions that have positive marginal utility and risk aversion.
