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
This paper demonstrates how to directly incorporate common value-investing idea into the portfolio optimization process.
Systematic testing of systematic trading strategies
This study reviews the various statistical methodologies that are in place to test multiple systematic trading strategies and implements these methodologies under simulation with known artificial trading rules in order to critically compare and evaluate…
The short-term Danish interbank market before, during and after the financial crisis
This paper studies the microstructure of the short-term uncollateralized Danish interbank market before, during and after the financial crisis, and into an era of negative interest rates.
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.
Polynomial upper and lower bounds for financial derivative price functions under regime-switching
In this paper, the authors present a new approach to bounding financial derivative prices in regime-switching market models from both above and below.
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.
Structural changes in the interbank market across the financial crisis from multiple core–periphery analysis
In this work, the authors employ the KM–ER algorithm to characterize the internal organization of eMID.
Networks of common asset holdings: aggregation and measures of vulnerability
This paper quantifies the interrelations induced among financial institutions by common asset holdings.
Covering the world: global evidence on covered calls
Typical covered call strategies may be decomposed, using a risk and performance attribution methodology, into three components: equity exposure, short volatility exposure and equity timing. This paper applies that attribution methodology to covered calls…
A latent trawl process model for extreme values
This paper presents a new model for characterizing temporal dependence in exceedances above a given threshold.
Managing adverse temperature conditions through hybrid financial instruments
This paper proposes temperature-based risk management using hybrid financial instruments built on weather derivatives.
Forward-looking and incentive-compatible operational risk capital framework
This paper proposes an alternative framework for setting banks’ operational risk capital, which allows for forward-looking assessments and limits gaming opportunities by relying on an incentive-compatible mechanism.
Modeling operational risk depending on covariates: an empirical investigation
In this paper, the authors apply a dynamic extreme value theory (EVT) model based on a nonhomogeneous Poisson process incorporating covariates to estimate frequency, severity and risk measures for operational risk.
An empirical study on credit risk management: the case of nonbanking financial companies
The aim of this paper is to predict future default behaviors of nonbank financial company customers using credit scores.
Why are investors’ mutual fund market allocations far from optimal?
In this paper, the authors analyze why the optimal portfolio of funds that investors may take under complete information and the actual structure of the mutual fund market differ.
