This paper studies the linkages between different aspects of preferences in the presence of risk increases of different degrees in the variance of consumption. We find that the effects on expected utility of risk increases in variance of consecutive degrees are in opposite directions. Applying this result to saving choice when either labour income or the interest rate is random, we obtain that the effects on the optimal level of saving of risk increases in variance of subsequent degrees are in opposite directions. Lastly, similar results are obtained for risk increases in the variance of the variance of consumption.
期刊介绍:
Decisions in Economics and Finance: A Journal of Applied Mathematics is the official publication of the Association for Mathematics Applied to Social and Economic Sciences (AMASES). It provides a specialised forum for the publication of research in all areas of mathematics as applied to economics, finance, insurance, management and social sciences. Primary emphasis is placed on original research concerning topics in mathematics or computational techniques which are explicitly motivated by or contribute to the analysis of economic or financial problems.
