Our research focuses on the relevance of the descriptive framework to the representation of decisional behavior aspects in financial instruments fair value models. This issue is analyzed in the case of stock options through three essays: The first paper gives rise to new behavioral factors...

Through this study we checked within the framework of the fair value model, the consistency between the hedge-accounting recommended by the IAS 39 and the objectives of the capital regulation in the banking industry. We conclude that the macro-hedge is the most appropriate approach given the...

Le thème central de cet ouvrage porte sur l'adéquation des représentations théoriques du comportement décisionnel des agents et sur ses implications pour la pertinence des mesures de la juste valeur des instruments financiers. L'ouvrage vise en premier lieu à mettre en perspective le rôle...

This research provides an alternative framework for the analysis of employee stock option exercise patterns. It develops a binomial model where the exercise decision obeys to a policy that maximizes the expected utility to a representative employee exhibiting preferences as described by the...

This paper examines the incentives from stock options for loss-averse employees subject to probability weighting. Employing the certainty equivalence principle, I built on insights from Cumulative Prospect Theory (CPT) to derive a continuous time model to value options from the perspective of a...

This research provides an alternative framework for the valuation of standard employee stock options and for the analysis of exercise behavior patterns. It develops a binomial model where the exercise decision obeys to a policy that maximizes the expected utility to a representative employee...
