Black, J. M.; Bulkley, George A ratio criterion for signing the effects of an increase in uncertainty. (English) Zbl 0679.90006 Int. Econ. Rev. 30, No. 1, 119-130 (1989). The authors consider the problem of maximizing expected utility E(u(X,b)) with respect to a real parameter b when there is an increase in risk, i.e., when the random variable X is substituted by another more dispersed one. The paper is based on work by J. Meyer and M. B. Ormiston [J. Econ. Theory 31, 153-169 (1983; Zbl 0519.90005)]. Further sufficient conditions are given such that an increase in risk results in a greater maximizing value of the parameter b.
