Multivariate systemic risk measures and computation by deep learning algorithms

A Doldi, Y Feng, JP Fouque, M Frittelli - Quantitative Finance, 2023 - Taylor & Francis
In this work, we propose deep learning-based algorithms for the computation of systemic
shortfall risk measures defined via multivariate utility functions. We discuss the key related …

Risk sharing with deep neural networks

M Burzoni, A Doldi, E Monzio Compagnoni - Quantitative Finance, 2024 - Taylor & Francis
We consider the problem of optimally sharing a financial position among agents with
potentially different reference risk measures. The problem is equivalent to computing the …

Strong Comonotonic Additive Systemic Risk Measures

H Wang, S Gong, Y Hu - Axioms, 2024 - mdpi.com
In this paper, we propose a new class of systemic risk measures, which we refer to as strong
comonotonic additive systemic risk measures. First, we introduce the notion of strong …

SIG-BSDE for Dynamic Risk Measures

N Agram, J Rems, ER Gianin - arXiv preprint arXiv:2408.02853, 2024 - arxiv.org
In this paper, we consider dynamic risk measures induced by backward stochastic
differential equations (BSDEs). We discuss different examples that come up in the literature …

Systemic risk models for disjoint and overlapping groups with equilibrium strategies

Y Feng, JP Fouque, R Hu, T Ichiba - Statistics & Risk Modeling, 2023 - degruyter.com
We analyze the systemic risk for disjoint and overlapping groups of financial institutions by
proposing new models with realistic game features. Specifically, we generalize the systemic …
