Benchmarking machine learning models to predict corporate bankruptcy
Based on a comprehensive sample, the authors benchmark machine learning models in the prediction of financial distress of publicly traded US firms, with gradient-boosted tress outperforming other models in one-year-ahead forecasts.
The quintic Ornstein-Uhlenbeck model for joint SPX and VIX calibration
A new model that jointly fits the smiles of VIX and SPX is presented
Bayesian backtesting for counterparty risk models
Utilising Bayesian methods, the authors put forward a new means for counterparty risk model backtesting which is both simple to implement and conceptually sound.
A modified hybrid feature-selection method based on a filter and wrapper approach for credit risk forecasting
This paper proposes the chi-squared with recursive feature elimination method: a means of feature-selection which aims to improve classification performance using fewer features.
Information geometry of risks and returns
An innovative product design framework and its geometric interpretation is introduced
The validation of different systemic risk measurement models
The authors incorporate a capital buffer to the DebtRank model and use data from China's banking industry to compare the proposed model with others.
Small and medium-sized enterprises’ time to default: an analysis using an improved mixture cure model with time-varying covariates
The authors put forward a method using a support vector machine to enhance the exploration of nonlinear covariate effects if SMEs never default while also considering time-varying and fixed covariates for the incidence and latency of an event.
What can we expect from a good margin model? Observations from whole-distribution tests of risk-based initial margin models
This paper offers a means of testing initial margin models based on their predictions of the whole future distribution of returns of the relevant portfolio which is demonstrated to be more powerful than typical backtesting approaches.
Target-date funds: lessons learned?
The authors return to the topic of their 2011 paper and investigate the maturation of target-date funds and their performance during the Covid-19 pandemic, finding that the funds have largely achieved their designation.
The information value of past losses in operational risk
The authors argue that past operational losses inform future losses at banks and that the information provided by past losses results from their capturing factors that are hard to quantify in other tests.
Application of the radial basis function in solving an operational risk management model: investigating the probability of bank survival with risk reserves
The authors investigate the probability of bank survival in relation to operational risk and risk reserve and calculate the amount of risk storage necessary to achieve the desired probability of survival.
Fat tails and optimal LDI portfolios
A portfolio optimisation technique for pension funds and insurance portfolios is presented
Does board diversity mitigate firm risk-taking? Empirical evidence from China
The authors explore the relationship between firm risk and both demographic and cognitive-oriented board diversity.
Instabilities in Cox proportional hazards models in credit risk
The authors explore possible instabilities in applying Cox PH models and conduct numerical studies to demonstrate the same linear specification error from APC models an occur in Cox PH estimation.
Banking on personality: psychometrics and consumer creditworthiness
This paper uses empirical methods to investigate how psychometric data can be used to augment traditional credit models.
An experimental study of capacity remuneration mechanisms in the electricity industry
The authors investigate the efficiency properties of energy market designs with regard new investments, reductions in unserved energy frequency and energy prices of a generic capacity remuneration mechanism impervious to the forward capacity market.
Locational arbitrage strategies for Shanghai crude futures
The authors investigate crude oil futures introduced on the Shanghai International Energy Exchange in March 2018 and the locational trading strategies they can provide and put forward an example of locational arbitrage hedged against foreign risk.
Scaling up hydrogen production in France: learning rates versus economies of scale strategies
The authors investigate hydrogen production infrastructure in an effort to offer a vision for electrolyzer planning which avoids sunk costs at an early stage.
Quantifying the economic benefits of payments modernization: the case of Canada’s large-value payment system
The authors analyze the economic benefits of the replacement of Canada’s large-value transfer system (LVTS) with the new system, Lynx.
A model for small basket equities financing
A haircut model for equity baskets based on credit and equity indexes is introduced
Sovereign credit risk modeling using machine learning: a novel approach to sovereign credit risk incorporating private sector and sustainability risks
The authors investigate the effect of spillover effects from private sector risks on sovereign debt risk and the impact of rising sustainability risks on sovereign credit risk using the XGBoost classification algorithm and model interpretability…
A dynamic program under Lévy processes for valuing corporate securities
The authors design and solve an extended structural model that accommodates arbitrary Lévy dynamics for the underlying firm’s asset value, realistic debt payment schedules, multiple seniority classes and various intangible assets.
The carbon equivalence principle: methods for project finance
A method to price the environmental impact of financial products is proposed
The relationship between crude oil futures and exchange rates in the context of the Covid-19 shock: a tale of two markets
The authors investigate the high-frequency intraday return and volatility transmission between crude oil futures prices and exchange rates during the 2020 Covid-19 pandemic in the Brent and INE markets.
