TLDR
In this paper, an analysis of the first step of the decision-making process of an individual decision maker among alternative risky ventures is presented, in terms of a single dimension such as money, both for the utility functions and for the probability distributions.Abstract:
Publisher Summary The choice of an individual decision maker among alternative risky ventures may be regarded as a two-step procedure. The decision maker chooses an efficient set among all available portfolios, independently of his tastes or preferences. Then, the decision maker applies individual preferences to this set to choose the desired portfolio. The subject of this chapter is the analysis of the first step. It deals with optimal selection rules that minimize the efficient set by discarding any portfolio that is inefficient in the sense that it is inferior to a member of the efficient set, from point of view of each and every individual, when all individuals' utility functions are assumed to be of a given general class of admissible functions. The analysis presented in the chapter is carried out in terms of a single dimension such as money, both for the utility functions and for the probability distributions. However, the results may easily be extended, with minor changes in the theorems and the proofs, to the multivariate case. The chapter explains a necessary and sufficient condition for efficiency, when no further restrictions are imposed on the utility functions. It presents proofs of the optimal efficiency criterion in the presence of general risk aversion, that is, for concave utility functions.read more

Investment decisions under uncertainty—A methodological review on forest science studies
Patrick Hildebrandt,Thomas Knoke +1 more
TL;DR: In this paper, a comprehensive overview on techniques for financial decision-making under uncertainty and developing future research needs is presented, and the authors conclude that the maximization of financial robustness is probably the most adequate approach for many long-term decisions in forestry.

The Utility Analysis of Choices Involving Risk
TL;DR: In this paper, the authors suggest that an important class of reactions of individuals to risk can be rationalized by a rather simple extension of orthodox utility analysis, i.e., individuals frequently must, or can, choose among alternatives that differ, among other things, in the degree of risk to which the individual will be subject.

The Existence of Probability Measures with Given Marginals
TL;DR: In this article, the existence of probability distributions with given marginals is studied under typically weaker assumptions, than those which are required by the use of Theorem 1, and necessary and sufficient conditions for a sequence of probability measures to be the sequence of distributions of a martingale, an upper semi-martingale or of partial sums of independent random variables.
