Covariance estimation for risk-based portfolio optimization: an integrated approach
This paper presents a stochastic optimization framework for integrating time-varying factor covariance models in a risk-based portfolio optimization setting.
Forecasting volatility and market returns using the CBOE Volatility Index and its options
This paper examines the CBOE VIX, the VIX options’ implied volatility and the smirks associated with these options.
Incorporating small-sample defaults history in loss given default models
This paper proposes a methodology for estimating loss given default (LGD) that accounts for small default sample sizes.
Agency problems in multinational banks: does parent complexity affect the risk-taking of subsidiaries?
This paper empirically reviews the relationship between the geographical complexity of parent-groups and the risk-taking behavior of subsidiaries using a panel of data for Polish domestically owned and foreign-owned banks covering the years 2008–17.
Calibration of rating grades to point-in-time and through-the-cycle levels of probability of default
The paper argues for the need for and importance of the dual calibration of a probability of default (PD) model (ie, calibration to both point-in-time and through-the-cycle PD levels.)
Rainbows and transforms: semi-analytic formulas
In this paper the authors show how the techniques introduced by Hurd and Zhou in 2010 can be used to derive a pricing framework for rainbow options by using the joint characteristic function of the logarithm of the underlying assets.
Branching diffusions with jumps, and valuation with systemic counterparties
This paper extends the branching diffusion Monte Carlo method of Henry-Labordère et al to the case of parabolic partial differential equations with mixed local–nonlocal analytic nonlinearities.
Extreme value theory for operational risk in insurance: a case study
This study aims to test the sufficiency of the solvency capital requirement approach for calculating operational risk using the standard formula as defined in Solvency II.
A review of tree-based approaches to solving forward–backward stochastic differential equations
This paper looks at ways of solving (decoupled) forward–backward stochastic differential equations numerically using regression trees.
Evaluation of backtesting techniques on risk models with different horizons
In this study different value-at-risk (VaR) models are analyzed under different estimation approaches (filtered historical simulation, extreme value theory and Monte Carlo simulation) and backtested with different techniques.

Bergomi's skew-stickiness ratio is extended to the setting of variance swaps
A market scoring mechanism for trading of German electricity futures
This paper present a novel systematic commodity trading model utilizing a time series momentum strategy.
The role of management accounting practices in operational risk management: the case of Palestinian commercial banks
This paper follows an exploratory, descriptive approach to investigate the role that management accounting practices plays in managing operational risks in the Palestinian commercial banking sector.
Strong-hand conjecture: agent-based numerical simulation
Following the example of the Kim–Markowitz model, this study adopts similar mechanisms of market operation to perform computer simulations based on agent modeling on the financial market, where shares of one company and a bank account are available …
Multi-horizon forecasting for limit order books
A multi-step path is forecast using deep learning and parallel computing
Fighting Covid-19 in countries and operational risk in banks: similarities in risk management processes
This paper shows how banks managing operational risk and countries tackling Covid-19 could learn from each other to overcome obstacles in effectively mitigating major risks.
Forecasting natural gas price trends using random forest and support vector machine classifiers
In this paper, different machine learning approaches are applied to forecasting future yearly price trends in the natural gas Title Transfer Facility market in the Netherlands.
Using equity, index and commodity options to obtain forward-looking measures of equity and commodity betas and idiosyncratic variance
This paper presents a means to extract forward-looking measures of equity and commodity betas, and idiosyncratic variance.
Backtesting of a probability of default model in the point-in-time–through-the-cycle context
This paper presents a backtesting framework for a probability of default model, assuming that the latter is calibrated to both point-in-time and through-the-cycle levels.
Approximating lifetime expected credit loss
Credit rating and collateral value's changes have a measurable impact on creditworthiness
Modeling nonmaturing deposits: a framework for interest and liquidity risk management
This paper presents a generic framework for modeling nonmaturing deposits that can be used by banks for interest and liquidity risk management, funds transfer pricing and dynamic balance sheet management.
Time-varying tail dependence networks of financial institutions
In this paper time-varying tail dependence networks are constructed to investigate the complex interdependencies in the financial system.
Reinvestigating international crude oil market risk spillovers
This paper develops a copula-GARCH-MIDAS model to estimate the joint probability distribution of multivariate variables, and then derives CoVaR-type risk measures.
