A network-based method for visual identification of systemic risks
This paper introduces the topic of network visualization to the journal by proposing the use of a combination of data reduction techniques and overlays that allow detection of large-scale patterns and outlier activity.
Credit risk spillover between financials and sovereigns in the euro area, 2007–15
This paper proposes a method based on Granger causality to measure the level of contagion between financial institutions and sovereigns.
Close communications: hedge funds, brokers and the emergence of a consensus trade
This paper examines the network of communication practices among hedge fund managers.
Outperforming benchmarks with their derivatives: theory and empirical evidence
This paper looks for optimal explicit constructions and empirical tests in regards to pricing and hedging derivatives with coherent risk measures.
Suboptimality in portfolio conditional value-at-risk optimization
This paper considers the portfolio optimization problem, with conditional value-at-risk as the objective.
Bank fraud and the macroeconomy
This paper empirically tests for correlations between fraud and the macroeconomy.
A maximum entropy approach to the loss data aggregation problem
This paper examines and compares alternative ways of solving the problem of determining the density of aggregate losses.
A simulation comparison of quantile approximation techniques for compound distributions popular in operational risk
The objective of this paper is to compare numerical approximation techniques in terms of their practical usefulness and potential applicability in an operational risk context.
Evaluating operational risk by an inhomogeneous counting process based on Panjer recursion
This paper proposes a new approach for determining OpVaR using an inhomogeneous counting process based on Panjer recursion as the frequency distribution.
Central counterparties and banks: vive la difference
This paper highlight the key differences between CCPs and banks in terms of roles, risk profiles, balance sheets and systemic characteristics, and the implications of these differences for CCP risk management and regulation.
Dynamic credit score modeling with short-term and long-term memories: the case of Freddie Mac’s database
This paper investigates the two mechanisms of memory, short-term memory and long-term memory, in the context of credit risk assessment.
“Incomplete demutualization” and financial market infrastructure: central counterparty ownership and governance after the crisis of 2008–9
This paper examines risk management governance challenges of the demutualized CCP ownership model and the incentives faced by “incomplete demutualization”, where clearing members remain the ultimate underwriters of CCP default risk.
Value-at-risk time scaling: a Monte Carlo approach
This paper discusses a VaR time-scaling approach based on fitting a distribution function so as to apply a Monte Carlo simulation to determine long-term VaR.
Skin in the game: central counterparty risk controls and incentives
The authors discuss the incentives created by the structure of CCPs’ default waterfalls, drawing out the role of transparency and governance in ensuring effective incentives.
A framework for market, credit and transfer risk aggregation and stress testing
The authors develop a framework that consistently and fully integrates the market, credit and country transfer risks of a general portfolio of financial assets in a multi-period setup.
Market pricing of credit linked notes: the influence of the financial crisis
This paper analyzes whether the financial crisis of 2007–9 had an effect on the mispricing of CLNs.
Contingent credit default swaps: accurate and approximate pricing
This paper analyzes the pricing of contingent credit default swaps.
A credit portfolio framework under dependent risk parameters: probability of default, loss given default and exposure at default
This paper introduces a credit portfolio framework that allows for dependencies between default probabilities, secured and unsecured recovery rates and exposures at default (EADs).
An application of sensitivity analysis to hedge funds
This paper investigates a sample of 142 live hedge funds via a DEA sensitivity analysis using a super-efficiency model.
Central counterparties need thicker skins
The paper makes an important contribution to this ongoing dialogue by proposing a set of principles and an analytical framework for calibrating skin-in-the-game contributions.
