The stochastic-volatility, jump-diffusion optimal portfolio problem with jumps in returns and volatility
The risk-averse optimal portfolio problem is treated with consumption in continuous time for a stochastic jump-volatility-jump-diffusion (SJVJD) model for both the risky asset and the volatility.
The impact of retail payment innovations on cash usage
This study examines the effect of retail payment innovations on the use of cash at the point of sale.
Quantifying irrational sentiment
The author uses behavioral finance theory to create a measure that detects when stock markets become irrational.
Analysis of the use and impact of limits
In this paper, we analyze the use and impact of limits in TARGET2. Limits in the form of bilateral or multilateral debit limits are a liquidity management feature in TARGET2.
Hedging iTraxx credit default swap index trading on an intraday basis: an empirical study
In this paper we examine the effectiveness of intraday hedging models for credit default swap index trading by means of more liquidly traded exchange-based futures contracts.
Momentum strategies with the L1 filter
We discuss various implementations of L1 filtering in order to detect some properties of noisy signals.
Short-rate joint-measure models
A joint-measure model combining Q-measure and P-measure
Path-dependent volatility

A Fourier approach to the computation of conditional value-at-risk and optimized certainty equivalents
We consider the class of risk measures associated with optimized certainty equivalents.
Suitability of capital allocations for performance measurement
Capital allocation principles are used in various contexts in which the risk capital or the cost of an aggregate position has to be allocated between its constituent parts.
Modeling a risk-based criterion for a portfolio with options
The presence of options in a portfolio fundamentally alters the portfolio's risk and return profiles when compared with an all-equity portfolio. In this paper, we advocate modeling a risk-based criterion for optioned portfolio selection and rebalancing…
General covariance, the spectrum of Riemannium and a stress test calculation formula

Optimal trading under proportional transaction costs
The theory of optimal trading under proportional transaction costs has been considered from a variety of perspectives. In this paper, Richard Martin shows that all results can be interpreted using a universal law through trading algorithm design
Adjoint credit risk management
Adjoint algorithmic differentiation is one of the principal innovations in risk management in recent times. Luca Capriotti and Jacky Lee show how this technique can be used to compute real-time risk for credit products, even those valued with fast semi…
