## Optimal Portfolio Liquidation with Limit Orders

by Olivier Guéant, Charles-Albert Lehalle & Joaquin Fernandez Tapia This paper addresses the optimal scheduling of the liquidation of a portfolio using a new angle. Instead of focusing only on the scheduling aspect like Almgren and Chriss in [2], or … Continue reading

## Dealing with the Inventory Risk

by Olivier Guéant, Charles-Albert Lehalle & Joaquin Fernandez Tapia Market makers have to continuously set bid and ask quotes for the stocks they have under consideration. Hence they face a complex optimization problem in which their return, based on the bid-ask … Continue reading

## From infinity to one: the reduction of some MFGs to planning problems

by Olivier Guéant This paper presents recent results from Mean Field Game theory underlying the intro- duction of common noise that imposes to incorporate the distribution of the agents as a state variable. Starting from the usual mean field games … Continue reading

## Stochastic Target Problems with Controlled Loss in Jump Diffusion Models

By Ludovic Moreau Stochastic Target Problems with Controlled Loss in Jump Diffusion Models In this paper, we consider a mixed diffusion version of the stochastic target problem introduced in [3]. This consists in finding the minimum initial value of a … Continue reading

## On a mean field game approach modeling congestion and aversion in pedestrian crowds

By Aimé Lachapelle & Marie-Therese Wolfram (Cahier de la Chaire n°40) In this paper we present a new class of pedestrian crowd models based on the mean field games theory introduced by Lasry and Lions in 2006. This macroscopic approach … Continue reading

## A class of DCC asymmetric GARCH models driven by exogenous variables

By Jean-Michel Zakoïan (Cahier de la Chaire n°39) This paper considers Dynamic Conditional Correlations (DCC) GARCH models in which the time-varying coefficients, including the conditional correlation matrix, are functions of the realizations of an exogenous stochastic process. Time series generated … Continue reading

## A structural risk-neutral model for pricing and hedging power derivatives

By René Aïd, Luciano Campi & Nicolas Langrené (Cahier de la Chaire n°38) We develop a structural risk-neutral model for energy market modifying along several directions the approach introduced in [Aïd et al., 2009]. In particular a scarcity function is … Continue reading

## Statistical properties of derivatives: a journey in term structures

By Delphine Lautier & Franck Raynaud (Cahier de la Chaire n°37) This article presents an empirical study of thirteen derivative markets for commodity and financial assets. This paper goes beyond statistical analysis by including the maturity as a variable for … Continue reading

## Detecting the Maximum of a Mean-Reverting Scalar Diffusion

By Gilles-Edouard Espinosa & Nizar Touzi (Cahier de la Chaire n°36) Let X be a mean reverting scalar process, X the corresponding running maximum, T0 the first time X hits the level zero and ` a loss function, mainly increasing and … Continue reading

## Large liquidity expansion of super-hedging costs

By Dylan Possamai, H. Mete Soner & Nizar Touzi (Cahier de la Chaire n°35) We consider a financial market with liquidity cost as in Cetin, Jarrow and Protter (2004) where the supply function depends on a parameter with corresponding to … Continue reading

## Wellposedness of Second Order Backward SDEs

By H. Mete Soner, Nizar Touzi & Jianfeng Zhang (Cahier de la Chaire n°34) We provide an existence and uniqueness theory for an extension of backward SDEs to the second order. While standard Backward SDEs are naturally connected to semilinear … Continue reading

## Weak Dynamic Programming Principle for Viscosity Solutions

By Bruno Bouchard & Nizar Touzi (Cahier de la Chaire n°33) We prove a weak version of the dynamic programming principle for standard stochastic control problems and mixed control-stopping problems, which avoids the technical difficulties related to the measurable selection argument. In … Continue reading
