Risk and Uncertainty Aversion with Multidimensional Consequences

نویسنده

  • ALDO MONTESANO
چکیده

In a preceding paper (Montesano, 1999b) a systematic set of definitions on risk and uncertainty aversion was introduced with regard to unidimensional lotteries and acts. Taking into account only the preference preordering over the set of all possible lotteries and acts represented by the certainty equivalent function, many propositions were introduced and demostrated on global and local risk and uncertainty aversion, comparative risk and uncertainty aversion, and aversion to increasing risk and uncertainty.

On Risk Aversion, Classical Demand Theory, and KM Preferences

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 opti...

Risk Aversion and Herd Behavior in Financial Markets∗

We show that differences in investors risk aversion can generate herd behavior in stock markets where assets are traded sequentially. This in turn prevents markets from being efficient in the sense that Þnancial market prices do not converge to the asset’s fundamental value. The informational efficiency of the market depends on the distribution of the risky asset across risk averse agents. Thes...

On multivariate prudence

In this paper we extend the theory of precautionary saving to the case in which uncertainty is multidimensional and we develop a matrix-measure of multivariate prudence. Furthermore, we characterize comparative prudence, decreasing and increasing prudence, the e¤ect of uncertainty on the marginal propensity to consume out of wealth, and the Drèze-Modigliani substitution e¤ect in this multivaria...

The 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...

TRIPLE PREFERENCE THEORY OF CHOICE UNDER RISK AND UNCERTAINTY Janne Gustafsson

This paper develops a theory of choice under risk and uncertainty which, together with the associated definition of risk aversion, separates the concepts of risk aversion and diminishing marginal utility from each other. Building on separate definition of the decision maker’s two elementary preference relations—preferences over lotteries and preferences over consequences—and a set of consistenc...
