On Risk Aversion, Classical Demand Theory, and KM Preferences

چکیده
Building on Kihlstrom and Mirman (1974)’s formulation of risk aversion in the case of multidimensional utility functions, we study the effect of risk aversion on optimal behavior in a general consumer’s maximization problem under uncertainty. We completely characterize the relationship between changes in risk aversion and classical demand theory. We show that the effect of risk aversion on optimal behavior depends on the income and substitution effects. Moreover, the effect of risk aversion is determined not by the riskiness of the risky good, but rather the riskiness of the utility gamble associated with each decision.

Risk premiums and certainty equivalents of loss-averse newsvendors of bounded utility
Loss-averse behavior makes the newsvendors avoid the losses more than seeking the probable gains as the losses have more psychological impact on the newsvendor than the gains. In economics and decision theory, the classical newsvendor models treat losses and gains equally likely, by disregarding the expected utility when the newsvendor is loss-averse. Moreover, the use of unbounded utility to m...
متن کاملExplaining Heterogeneity in Risk Preferences Using a Finite Mixture Model
This paper studies the effect of the space (distance) between lotteries' outcomes on risk-taking behavior and the shape of estimated utility and probability weighting functions. Previously investigated experimental data shows a significant space effect in the gain domain. As compared to low spaced lotteries, high spaced lotteries are associated with higher risk aversion for high probabilities o...
متن کاملA behavioral theory of the consumer under reference dependent preferences and certainty:∗
We extend classical consumer theory to account for reference dependence and loss aversion under complete certainty. The classical results obtain as a special case. Several new results emergethere is a kink in the demand curve at the reference point, consumers are subject to money illusion, and some kinds of inconsistencies of preferences can be accounted for. However, the reference dependent mo...

The important defect of the previous models , is assumed that consumer behavior is based on logic and with a rise in the price their consumption decreased and they accurately have no problems with their control. However, various parameters such as lifestyle, habits and emotions and something like that can be effective. In this paper, we use the new model called the OLG model and the CRRA funct...
متن کاملThe Income Effect under Uncertainty: A Slutsky-like Decomposition with Risk Aversion
We study the effect of changing income on optimal decisions in the multidimensional expected utility framework with strongly separable preferences. Using the Kihlstrom and Mirman (1974) (KM) utility representation, we show that the effect of changing income can be decomposed into a modified income effect linked to the classical income effect and an effect representing attitudes to risk, modifie...
