Hedging under an expected loss constraint with small transaction costs
Bouchard, Bruno; Moreau, Ludovic; Soner, Mete - HAL - 2013
We consider the problem of option hedging in a market with proportional transaction costs. Since super-replication is … very costly in such markets, we replace perfect hedging with an expected loss constraint. Asymptotic analysis for small … transactions is used to obtain a tractable model. A general expansion theory is developed using the dynamic programming approach …

Dynamic hedging of portfolio credit derivatives
Cont, Rama; Kan, Yu Hang - HAL - 2011
We compare the performance of various hedging strategies for index collateralized debt obligation (CDO) tranches across … a variety of models and hedging methods during the recent credit crisis. Our empirical analysis shows evidence for …-dimensional bottom-up models perform better than simpler top-down models. When it comes to hedging, top-down and regression-based hedging …

Disagreement-Based Trading and Speculation: Implications for Financial Regulation and Economic Theory
Biondi, Yuri - HAL - 2011
Lynn Stout's paper develops an insightful legal-economic analysis of speculative trading. From one hand, the paper discusses the legal-economic framework of speculation and its recent transformation, making reference to the case of derivatives markets crash (and related financial crisis) of...

Backtesting Value-at-Risk: From Dynamic Quantile to Dynamic Binary Tests
Dumitrescu, Elena-Ivona; Hurlin, Christophe; Pham, Vinson - HAL - 2012
In this paper we propose a new tool for backtesting that examines the quality of Value-at- Risk (VaR) forecasts. To date, the most distinguished regression-based backtest, proposed by Engle and Manganelli (2004), relies on a linear model. However, in view of the di- chotomic character of the...

Non-stationarity and meta-distribution
Guegan, Dominique - HAL - 2008
In this paper we deal with the problem of non-stationarity encountered in a lot of data sets, mainly in financial and economics domains, coming from the presence of multiple seasonnalities, jumps, volatility, distorsion, aggregation, etc. Existence of non-stationarity involves spurious behaviors...

Forecasting VaR and Expected Shortfall using Dynamical Systems: A Risk Management Strategy
Caillault, Cyril; Guegan, Dominique - HAL - 2009
Using non-parametric and parametric models, we show that the bivariate distribution of an Asian portfolio is not stable along all the period under study. We suggest several dynamic models to compute two market risk measures, the Value at Risk and the Expected Shortfall: the RiskMetrics...

Enterprise risk management: A process for enhanced management and improved performance
Gates, Stephen; Nicolas, Jean-Louis; Walker, Paul L. - HAL - 2012
Some company boards of directors and management teams are still reluctant to embrace enterprise risk management (ERM) because of the uncertainty regarding its value to the bottom line. A survey of audit and risk management executives suggests that the use of ERM leads to increased management...

Farm risk management between normal business risk and climatic/market shocks
Cordier, Jean - HAL - 2008
Farm risk management for income stabilization is on-going issue. An applied work has been performed to measure farm risk using a stochastic model. Risk management tools, with symmetric as well as asymmetric impacts, are then tested and compared through ad hoc statistics. Normal farm business...

An Econometric Study of Vine Copulas
Guegan, Dominique; Maugis, Pierre-André - HAL - 2010
We present a new recursive algorithm to construct vine copulas based on an underlying tree structure. This new structure is interesting to compute multivariate distributions for dependent random variables. We proove the asymptotic normality of the vine copula parameter estimator and show that...
