Market liquidity risk refers to the degree to which large size transactions can be carried out in a timely fashion with a minimal impact on prices. Emphasized by the G10 report in 1993 and the BIS report in 1997, it is viewed as one factor of destabilization in the financial markets, as...

Usually partial equilibrium models used for pricing financial derivatives rely on price equilibrium dynamics which doesn’t explicitly take the trade size into account. However any price is implicitly based on the balance between supply and demand to the extent that the exchanged quantity...

In the framework of Galichon, Henry-Labordère and Touzi, we consider the model-free no-arbitrage bound of variance option given the marginal distributions of the underlying asset. We first make some approximations which restrict the computation on a bounded domain. Then we propose a gradient...

We give a study to the algorithm for semi-linear parabolic PDEs in Henry-Labordère (2012) and then generalize it to the non-Markovian case for a class of Backward SDEs (BSDEs). By simulating the branching process, the algorithm does not need any backward regression. To prove that the numerical...

We provide a general Doob-Meyer decomposition for $g$-supermartingale systems, which does not require any right-continuity on the system. In particular, it generalizes the Doob-Meyer decomposition of Mertens (1972) for classical supermartingales, as well as Peng's (1999) version for...

Price regulation and competition patterns in the ethical drug industry in france This article gives the results of an econometric modelization of the ethical drugs price and quantity determination institutionnal process for France. From price and promotion elasticities, it is shown that...

Efficiency of financial markets is one of the most studied subjects in theoretical finance. Formalization of this idea is realised by the random walk model. Numerous tests have been developed to validate the hypothesis of identically and independently distributed innovations. But the results of...

Management control practices are influenced by different professional groups, their interpretations and power struggles. We study a company whose strategy and daily management rely on non financial stakes, notably upon the concept of “brand”. We show how management accountants introduce a...
