Value-at-risk models: a systematic review of the literature
The authors conduct a systematic literature review of value-at-risk models to determine which models are most often used and whether any change in model popularity occurred after the 2007-9 financial crisis.
A theory for combinations of risk measures
This paper investigates combinations of risk measures under no restrictive assumption on the set of alternatives, obtaining results regarding the preservation of properties and acceptance sets for these combinations of risk measures.
Mitigating margin procyclicality: the effectiveness of anti-procyclicality measures during the Covid-19 stress event
This paper analyzes the effectiveness of APC measures implemented by central counterparties for clearing member and client margins, with effectiveness sensitive to the details of calibration and type of portfolios to which the measure is applied.
Payment coordination and liquidity efficiency in wholesale payments systems
The authors investigate the two settlement mechanisms found in the Lynx payments system, finding that the highest liquidity efficiency is achieved if all payments were sent to the mechanism allowing offsetting.

Climate-policy-relevant sectors and credit risk
This paper explores the relationship between banks exposed to climate-policy-relevant sectors and credit risk, finding that banks exposed to higher carbon emitting sectors are subject to greater credit risk than those exposed to less carbon emitting…

Dynamic class-imbalanced financial distress prediction based on case-based reasoning integrated with time weighting and resampling
The authors put forward a dynamic class-imbalanced CBR FDP model which is shown, using data from Chinese listed companies, to outperform static and dynamic CBR FDP models without resampling or time weighting.
Calibration alternatives to logistic regression and their potential for transferring the statistical dispersion of discriminatory power into uncertainties in probabilities of default
This paper compares four calibration approaches to linear logistic regression in credit risk estimation and proposes two new single-parameter families of differentiable functions as candidates for this regression.
Estimating risks of European option books using neural stochastic differential equation market models
The authors investigate how arbitrage-free neural stochastic differential equation market models can produce realistic scenarios for the joint dynamics of multiple European options on a single underlying and demonstrate how they can be used as a risk…
