New historical bootstrap value-at-risk model
This paper presents a new value-at-risk (VaR) model for the estimation of market risk in banks and other financial institutions.
Pricing multidimensional financial derivatives with stochastic volatilities using the dimensional-adaptive combination technique
In this paper, the authors present a new and general approach to price derivatives based on the Black–Scholes partial differential equation (BS-PDE) in a multidimensional setting.
Volatility risk structure for options depending on extrema
In this paper, the authors give a decomposition formula to calculate the vega index (sensitivity with respect to changes in volatility) for options with prices that depend on the extrema (maximum or minimum) and terminal value of the underlying stock…
Cumulative prospect theory and mean–variance analysis: a rigorous comparison
This paper proposes a numerical optimization approach that can be used to solve portfolio selection problems including several assets and involving objective functions from cumulative prospect theory (CPT).
A hybrid tree/finite-difference approach for Heston–Hull–White-type models
In this paper, the authors study a hybrid tree/finite-difference method, which allows us to obtain efficient and accurate European and American option prices in the Heston–Hull– White and Heston–Hull–White2d models.
Standardized measurement approach extension to integrate insurance deduction into operational risk capital requirement
The SMA proposed in BCBS (2016) presents several issues: in particular, its two components are not sufficient to discriminate banking institutions by risk profile, thus penalizing the more virtuous ones. This paper describes a possible solution to extend…
Efficient trading in taxable portfolios
This paper determines life-cycle trading strategies for portfolios subject to the US tax system.
Exploration risk in international oil and gas shareholder returns
This paper focuses upon the oil and gas industry, examining the association between exploration activity risk and company shareholder returns.
Portfolio concentration and equity market contagion: evidence on the “flight to familiarity” across indexing methods
This paper sheds light on the entanglement of index weighting schemes.
A Darwinian view on internal models
In this paper, Paul Embrechts reviews discussions on regulation within banking (Basel III and IV) and insurance (Solvency II and Swiss Solvency Test (SST)) from a historical, personal and academic point of view.
Risk management and regulation
The author presents a systematic review of the chronological evolution of risk management, in tandem with financial innovation and methodological advances in derivatives pricing.
Derivatives pricing under bilateral counterparty risk
The authors consider risk-neutral valuation of a contingent claim under bilateral counterparty risk using the well-known reduced-form approach.
Networks of log returns and volatilities of international stock market indexes
In this paper, the author builds dynamic networks based on correlation and transfer entropy, using both the log returns and the volatilities of 97 stock market indexes from various parts of the world between 2000 and 2016
Systemic risk management in financial networks with credit default swaps
In this paper the authors study insolvency cascades in an interbank system, in which banks are permitted to insure their loans with credit default swaps sold by other banks.
Lifecycle investing with the profitable dividend yield strategy: simulations and nonparametric analysis
Using simulations, the author shows that life-cycle investing implemented on highly profitable and high dividend yield stocks (the profitable dividend yield strategy) provides a compelling solution to the suboptimality problem by leveraging on the…
Enhancing enterprise value by trading options
This paper considers the problem of enhancing an investment activity by regularly adding an option trade to the portfolio mix and presented results for the single underlier of the S&P 500 index, with the underlying activity being either long the index or…
Ranking the economic importance of countries and industries
The authors present a methodological framework for quantifying interdependencies in the global market and for evaluating risk levels in the worldwide financial network.
Asset price bubbles and risk management
The purpose of this paper is to review the literature on asset price bubbles to study the impact that the existence of bubbles has on standard risk management methodologies.
Fast, accurate and straightforward extreme quantiles of compound loss distributions
In this paper, the author presents an easy-to-implement, fast and accurate method for approximating extreme quantiles of compound loss distributions (frequency + severity), which are commonly used in insurance and operational risk capital models.
Nonmonotonic trade-offs of tiering in a large-value payment system
This paper studies tiering in the case of a national payment system in an emerging economy: the large-value payment system Sistemas de Cuentas de Depósito (CUD, the Spanish acronym for the Deposit Accounts System) operated by the Colombian central bank.
Nondefault loss allocation at central counterparties
In this paper, the authors answer three questions about the appropriate allocation of nondefault losses at central counterparties.
Estimating “hedge and auction” liquidation costs in central counterparties: a closeout risk approach
This paper shows how the closeout risk framework can be extended to realistically represent and simulate the potential outcomes of “hedge and auction” default management policies currently implemented by several major central counterparties.

This paper discusses key features of fighting behavioral risk in the business line of operations as the central hub for all transactions in a bank.
Behavioral risks at the systemic level
