Measures of systemic risk

Z Feinstein, B Rudloff, S Weber - SIAM Journal on Financial Mathematics, 2017 - SIAM
Systemic risk refers to the risk that the financial system is susceptible to failures due to the
characteristics of the system itself. The tremendous cost of systemic risk requires the design …

Optimal network compression

H Amini, Z Feinstein - European Journal of Operational Research, 2023 - Elsevier
This paper introduces a formulation of the optimal network compression problem for
financial systems. This general formulation is presented for different levels of network …

Pricing of debt and equity in a financial network with comonotonic endowments

T Banerjee, Z Feinstein - Operations Research, 2022 - pubsonline.informs.org
In this paper, we present formulas for the valuation of debt and equity of firms in a financial
network under comonotonic endowments. We demonstrate that the comonotonic setting …

Conditional systemic risk measures

A Doldi, M Frittelli - SIAM Journal on Financial Mathematics, 2021 - SIAM
We investigate to which extent the relevant features of (static) Systemic Risk Measures can
be extended to a conditional setting. After providing a general dual representation result, we …

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 …

Dual representations for systemic risk measures based on acceptance sets

M Arduca, P Koch-Medina, C Munari - Mathematics and Financial …, 2021 - Springer
We establish dual representations for systemic risk measures based on acceptance sets in a
general setting. We deal with systemic risk measures of both “first allocate, then aggregate” …

Set-valued shortfall and divergence risk measures

Ç Ararat, AH Hamel, B Rudloff - International Journal of Theoretical …, 2017 - World Scientific
Risk measures for multivariate financial positions are studied in a utility-based framework.
Under a certain incomplete preference relation, shortfall and divergence risk measures are …

Time consistency for scalar multivariate risk measures

Z Feinstein, B Rudloff - Statistics & Risk Modeling, 2022 - degruyter.com
In this paper we present results on dynamic multivariate scalar risk measures, which arise in
markets with transaction costs and systemic risk. Dual representations of such risk measures …

Set-valued backward stochastic differential equations

Ç Ararat, J Ma, W Wu - The Annals of Applied Probability, 2023 - projecteuclid.org
In this paper, we establish an analytic framework for studying set-valued backward
stochastic differential equations (set-valued BSDE), motivated largely by the current studies …

A new coherent multivariate average-value-at-risk

K Uğurlu - Optimization, 2023 - Taylor & Francis
A new operator for handling the joint risk of different sources has been presented and its
various properties are investigated. The problem of risk evaluation of multivariate risk …
