This paper studies portfolio allocation in the international financial market when investors exhibit ambiguity aversion towards assets issued in foreign locations. Entrepreneurs located in each country have access to a risky technology and want to attract capital. The authors characterize...

Author's abstract. Motivated by many applications such as typical blockbuster product launches, we address in this paper, an inventory/production rollover process between an old and a new product, with a random availability/admissibility date for the new product. The optimization problem...

This paper proposes a model of the decision-maker’s confidence in his probability judgements, in terms of an implausibility measure – a real-valued function on the set of probability functions. A decision rule is axiomatised according to which the decision-maker evaluates acts using sets of...

Les notions de point de référence et d’aversion aux pertes sont deux éléments essentiels de la prospect theory, qui constitue à ce jour la théorie la plus reconnue concernant la représentation de la prise de décision individuelle dans le risque. L’objectif de cet article est de...

In a recent paper, Machina (2008) suggested choice problems in the spirit of Ellsberg (1961) which challenge tail-separability, an implication of Choquet Expected Utility (CEU) to a similar extent as the Ellsberg paradox challenged the sure-thing principle implied by Subjective Expected Utility...

This paper is concerned with the representation of preferences which do not satisfy the ordinary axioms for state-independent utilities.

Zeno's "dichotomy" paradox of the runner and the sorites paradox exhibit certain interesting similarities. Both of them involve a long series of steps, each of which seems legitimate, but which, taken together, apparently lead to an unacceptable conclusion. In this article, a particular...

This paper elicits an additively separable representation of preferences in the Savage framework (where the objects of choice are acts: measurable functions from an infinite set of states to a potentially finite set of consequences). A preference relation over acts is represented by the integral...

In this paper, we investigate the optimal timing for deep geological disposal of nuclear waste. Our model is based on the real options approach to investment under uncertainty. In this context, the problem is similar to the optimal exercise policy for a perpetual American spread option. The...

Based on prior accounting literature and Simons’ framework (1990, 1995), the authors explore the use of budgets in PEU situations in a qualitative study. They conducted a field-based study and interviewed 14 senior sales and marketing managers from various industries, using projective...
