On the existence of personal equilibria

Laurence Carassus, Miklós Rásonyi

We consider an investor who, while maximizing his/her expected utility, also compares the outcome to a reference entity. We recall the notion of personal equilibrium and show that,…

Projective functions

Laurence Carassus, Massinissa Ferhoune

We study projective functions. We prove that projective functions generalise lower and upper-semianalytic ones while being stable by composition and difference. We show that the cl…

Robust No-Arbitrage under Projective Determinacy

Alexandre Boistard, Laurence Carassus, Safae Issaoui

Drawing on set theory, this paper contributes to a deeper understanding of the structural condition of mathematical finance under Knightian uncertainty. We adopt a projective frame…

Nonconcave Robust Utility Maximization under Projective Determinacy

Laurence Carassus, Massinissa Ferhoune

We study a general robust utility maximization problem in a discrete-time frictionless market. The investor is assumed to have a possibly infinite, random, nonconcave, and nondecre…

Discrete time optimal investment under model uncertainty

Laurence Carassus, Massinissa Ferhoune

We study a robust utility maximization problem in a general discrete-time frictionless market under quasi-sure no-arbitrage. The investor is assumed to have a random and concave ut…

Strategies with minimal norm are optimal for expected utility maximization under high model ambiguity

Laurence Carassus, Johannes Wiesel

We investigate an expected utility maximization problem under model uncertainty in a one-period financial market. We capture model uncertainty by replacing the baseline model $\mat…
