This paper provides a new hedge fund replication method, which extends Kat and Palaro (2005) and Papageorgiou, Remillard and Hocquard (2008) to multiple trading assets with both long and short positions. The method generates a target payoff distribution by the cheapest dynamic portfolio. It is regarded as an extension of Dybvig (1988) to continuous-time framework and dynamic portfolio optimizat...

I give a general class of preference representations conforming with the von Neumann-Morgenstern axioms, time consistency and additivity of welfare over time on certain outcomes (certainty additivity). I discuss whether precautionary decision rules are needed and in what sense. By explicitly taking care of the gauge freedom allowed for Bernoulli utility my representation theorem allows to relat...

This paper is an investigation of the third-degree stochastic dominance order which has been introduced in the context of risk analysis and is now receiving an increased attention in the area of inequality measurement. After observing that this partial order fails to satisfy the von Neumann-Morgenstern property in the space of random variables, we introduce strong and local third-degree stochas...

The set of competitive allocations in an exchange economy with indivisible goods of Shapley and Scarf (1974) is an important solution concept in the literature. In this paper, we consider a farsighted version of the von Neumann and Morgenstern stable set by using the farsighted approach of Chwe (1994) and by modifying the domination relation defined by Wako (1999) to incorporate farsightedness....

We analyze comparative static effects under uncertainty when a decision maker has mean-variance preferences and faces a generic, quasi-linear decision problem with both an endogenous risk and a background risk. In terms of mean-variance preferences, we fully characterize the effects of changes in the location, scale, and concordance parameters of the stochastic environment on optimal risk-takin...

Binary possibilistic utility unifies two previously proposed qualitative decision models: optimistic and pessimistic utilities. All these decision models have been axiomatized in a von Neumann-Morgenstern setting. These axiomatizations have shown the formal similarity of these qualitative utilities and expected utility. Unfortunately in this framework, the representation of uncertainty has to b...

We consider randomized public good mechanisms with optional participation. Preferences over lotteries are modeled using skew-symmetric bilinear (SSB) utility functions, a generalization of classic von Neumann-Morgenstern utility functions. We show that every welfare-maximizing mechanism entices participation and that the converse holds under additional assumptions. Two corollaries of our result...

The aim of this paper is to propose methods that incorporate equity concerns into cost utility analysis. The focus of the paper is on QALYs, but the results apply to health utility indices in general. Two interpretations of QALYs are considered: QALYs as (von Neumann Morgenstern) utilities and QALYs as measures of health. A justification is provided for aggregating consistently scaled "QALYs as...
