Nonparametric versus parametric expected shortfall
In this paper, the authors use influence functions as a basic tool to study unconditional nonparametric and parametric expected shortfall (ES) estimators with regard to returns data influence, standard errors and coherence.
The efficiency of the Anderson–Darling test with a limited sample size: an application to backtesting counterparty credit risk internal models
This paper presents a theoretical and empirical evaluation of the Anderson–Darling test when the sample size is limited.
International Financial Reporting Standard 9 expected credit loss estimation: advanced models for estimating portfolio loss and weighting scenario losses
In this paper, the authors propose a model to estimate the expected portfolio losses brought about by recession risk and a quantitative approach to determine the scenario weights.
The 2D tree–grid method
In this paper, the authors introduce a novel, explicit, wide-stencil, two-dimensional (2D) tree–grid method for solving stochastic control problems (SCPs) with two space dimensions and one time dimension, or, equivalently, the corresponding Hamilton…
Risk data validation under BCBS 239
Based on a survey of twenty-nine major financial institutions, this paper aims to advise banks and other financial services firms on what is needed to get ready for and become compliant with BCBS 239, especially in the area of risk data validation.
Parameter estimation, bias correction and uncertainty quantification in the Vasicek credit portfolio model
This paper is devoted to the parameterization of correlations in the Vasicek credit portfolio model. First, the authors analytically approximate standard errors for value-at-risk and expected shortfall based on the standard errors of intra-cohort…
Factor investing: get your exposures right!
This paper is devoted to the question of optimal portfolio construction for equity factor investing. The authors discuss the question of multifactor portfolio construction and show that the simplistic approaches often used by practitioners tend to be…
Optimal posting of collateral with recurrent neural networks
Pierre Henry-Labordère applies neural networks to a control problem approach for managing collateral
Estimating maturity profiles of nonmaturing deposits
This paper proposes a method to extract deposit lifetime data from individual account transactions.
Funding and credit risk with locally elliptical portfolio processes: an application to central counterparties
In this paper, the authors extend the scaling approach of Andersen et al (2017a) from a model driven by Brownian motion to one driven by an arbitrary isotropic Lévy process.
An efficient portfolio loss model
This paper develops a parsimonious model for evaluating portfolio credit derivatives dependent on aggregate loss.
Recursive estimation of the exponentially weighted moving average model
The aim of this paper is twofold: (i) to introduce two recursive estimation algorithms suitable for the EWMA process that are applicable for routine volatility predictions, and (ii) to investigate their prediction ability by comparing them with other…
Rating migrations of US financial institutions: are different outcomes equivalent?
This study employs a competing risks approach to examine the rating migrations of US financial institutions (FIs) during the period 1984–2006.
Proof-of-work blockchains and settlement finality: a functional interpretation
In this paper, the authors aim to provide an interpretation of the legal issue of settlement finality in the context of proof-of-work distributed ledger technology, such as the Bitcoin network.
Credit rating analysis based on the network of trading information
In this paper, the authors investigate a credit rating problem based on the network of trading information (NoTI).
Central counterparty anti-procyclicality tools: a closer assessment
This paper investigates whether the substantial focus placed on the procyclicality of initial margin reflects both the original concerns at the time of the 2007-8 financial crisis and the intrinsic 'modus operandi' of CCPs.
Default cascades and systemic risk on different interbank network topologies
This paper examines the relationship between the topology of interbank networks and their ability to propagate localized, idiosyncratic shocks across the banking sector via banks’ interbank claims on one another.
CVA wrong-way risk: calibration using a quanto CDS basis
Tsz-Kin Chung and Jon Gregory calibrate wrong-way risk with the help of quanto CDS values
Blockchain: transparency for energy markets in Chile (Prologue)
This paper is the prologue for our special issue on Blockchain-enabled Energy Markets.
Decentralized bottom-up energy trading using Ethereum as a platform
In this paper, the simulated environment of a hierarchical energy trading market using Ethereum’s smartcontract technology is created as a proof-of-concept of using blockchain technology in energy trading.
Path-dependent American options
In this paper, the authors investigate a path-dependent American option problem and provide an efficient and implementable numerical scheme for the solution of its associated path-dependent variational inequality.
Complexity reduction for calibration to American options
In this paper, the authors propose and investigate a new method for the calibration to American option price data.
