In this paper, the authors compare the data from three major clearing houses concerning tail losses and member concentration.
Portfolio optimization for American options
In this paper, the authors construct strategies for an American option portfolio by exercising options at optimal timings with optimal weights determined concurrently.
The optimal investment problem in stochastic and local volatility models
This paper considers the classical optimal investment allocation problem of Merton through the lens of some more modern approaches, such as the stochastic volatility and local volatility models.

Bank risk, bank bailouts and sovereign capacity during a financial crisis: a cross-country analysis
This paper analyzes the competitive effects of government bailout expectations on bank risk using a sample of banks in OECD countries from 2005 to 2015.
Is operational risk regulation forward looking and sensitive to current risks?
This paper evaluates the operational risk capital requirements of large US banks to determine whether they are forward looking, sensitive to banks’ current exposures and designed to allow for risk mitigation.
Harmonic distances, centralities and systemic stability in heterogeneous interbank networks
This paper investigates the effects of contagion in interbank-lending networks, with a special focus on the theoretical grounding of centrality measures.
A linguistics approach to solving financial services standardization
In this paper, the author looks at what issues are created through linguistic variation when users of a language or languages attempt to ensure that there is a shared conceptual understanding in the financial domain.
Measuring latent risk preferences: minimizing measurement biases
In this paper, the author uses a unique data set, containing the revealed risk preferences of 9235 subjects, elicited with four different methods, to estimate latent risk preferences.
Dilated convolutional neural networks for time series forecasting
In this paper, the authors present a method for conditional time series forecasting based on an adaptation of the recent deep convolutional WaveNet architecture.
Back to backtesting: integrated backtesting for value-at-risk and expected shortfall in practice
This paper aims to reflect the current state of the discussion on the validation of market risk forecasts by means of backtesting.
Calculating capital charges for sector concentration risk
This paper proposes a methodology to quantify capital charges for concentration risk when economic capital calculations are conducted within a multifactor Merton framework.
A three-state early warning system for the European Union
In this paper, the authors develop an early warning system for forecasting a financial crisis of the magnitude of the 2007–8 crisis for the European Union (the EU14).
Predictive fraud analytics: B-tests
In this paper, the authors look at B-tests: methods by which it is possible to identify internal fraud among employees and partners of the bank at an early stage.
A real option analysis on retiring existing coal-fired electricity plants in the United States
This paper looks at the conditions under which a reasonable green policy by a US state encourages the early replacement of existing coal plants with new natural gas plants.
A general framework for constructing bank risk data sets
This paper proposes a general framework for constructing bank risk data sets, which provides an integrated process from data sources to comprehensive risk data sets.
Value-ranked equity portfolios via entropy pooling

Vibrato and automatic differentiation for high-order derivatives and sensitivities of financial options
This paper deals with the computation of second-order or higher Greeks of financial securities. It combines two methods, vibrato and automatic differentiation (AD), and compares these with other methods.

Procyclicality of capital and portfolio segmentation in the advanced internal ratings-based framework: an application to mortgage portfolios
This paper investigates the procyclicality of capital in the advanced internal ratings based (A-IRB) Basel approach for retail portfolios, and identifies the fundamental assumptions required for stable A-IRB risk weights over the economic cycle.
Analytical expressions of risk quantities for composite models
In this paper, the authors obtain analytic expressions of different actuarial and statistical quantities for a general class of composite models derived from the McDonald’s family of probability distributions.
