A new nonlinear partial differential equation in finance and a method of its solution
In this paper, the author considers a special type of nonlinear PDE that arises by applying optimization to some financial problems.
Network Theory & Financial Risk | Kimmo Soramäki & Samantha Cook
Kimmo Soramäki and Samantha Cook walk you through network theory and analysis to help understand and overcome the risks associated with payment systems, exposure networks, trade networks and asset correlation networks.
A practical maturity assessment method for model risk management in banks
This paper proposes a qualitative method to assess the maturity of model risk management practices within banks.
A nonparametric local volatility model for swaptions smile
This paper proposes a nonparametric local volatility Cheyette model and applies it to pricing interest rate swaptions.
A vine copula–GARCH approach to corporate exposure management
This paper applies vine copulas with GARCH marginals to the problem of capturing asset dependence and tail dynamics for currency and commodity exposures commonly found in portfolios of global corporates.
An operational risk-based regime-switching model for stock prices
This paper proposes a new risk-based regime-switching model for stock prices to examine the impact of operational risk events on stock prices.
Local volatility models in commodity markets and online calibration
This paper introduces a local volatility model for the valuation of options on commodity futures by using European vanilla option prices.
Asset price bubbles and the quantification of credit risk capital with sensitivity analysis, empirical implementation and an application to stress testing
This paper presents an analysis of the impact of asset price bubbles on standard credit risk measures.
Estimating the tail shape parameter from option prices
In this paper, the author proposes a method to estimate the tail shape parameter of the risk-neutral density.
Inefficiency and bias of modified value-at-risk and expected shortfall
This paper compares mVaR and mES estimators with VaR and ES under normal and fat tailed t-distributions.
Comparing multivariate volatility forecasts by direct and indirect approaches
This paper investigates direct and indirect volatility evaluations in the multivariate framework by means of a Monte Carlo simulation
Risk management for private equity funds
This paper aims to fill a gap in the literature by developing the first comprehensive risk management framework for private equity fund investments.
A balanced approach to central counterparty margining
This paper is meant to serve as a comparison of the approaches and margin models employed by CCPs.
Managing market liquidity risk in central counterparties
This paper discusses the different approaches to incorporating market liquidity risk within a CCP’s default waterfall and the challenges that these approaches pose.
Initial margin model sensitivity analysis and volatility estimation
This paper presents a new approach to parameter selection based on the statistical properties of the worst loss over a margin period of risk estimated by the margin model under scrutiny.
Performance testing of margin models using time series similarity
This paper proposes a performance test based on empirical similarity that would account for margin shortfall, procyclicality and efficiency in a single score.
Initial margin estimations for credit default swap portfolios
This paper presents a clearinghouse framework to establish initial margin requirements for portfolios of credit default swap instruments.
Cleared margin setting at selected central counterparties
In this paper, the authors address one aspect of CCP risk management: initial margining practices. The paper provides a historical review of margining at selected CCPs as well as an overview of their current margin policies.
