This paper builds on "Collective Arbitrage and the Value of Cooperation" by Biagini et al. (2025, forthcoming in "Finance and Stochastics"), which introduced in discrete time the n…
On conditioning and consistency for nonlinear functionals
Edoardo Berton, Alessandro Doldi, Marco Maggis
We consider a family of conditional nonlinear expectations defined on the space of bounded random variables and indexed by the class of all the sub-sigma-algebras of a given underl…
