We study a class of robust, or worst case scenario, optimal control problems for jump diffusions. The scenario is represented by a probability measure equivalent to the initial probability law. We show that if there exists a control that annihilates the noise coefficients in the state equation...

Measuring the risk of a financial portfolio involves two steps: estimating the loss distribution of the portfolio from available observations and computing a ``risk measure" which summarizes the risk of the portfolio. We define the notion of ``risk measurement procedure", which includes both of...

RFID associated to ambient intelligence provide the basic interconnected network infrastructure for decentralized warehouses management and control. In this paper, we discuss benefits and barriers of decentralized approaches and how they can be adopted in warehouses. We examine mechanisms,...

Within a standard framework à la Arrow-Debreu, we investigate the dynamics emerging from the interactions of heterogeneous households and firms that are adaptive price setters and financially constrained. We show that depending on the stringency of the financial constraints the model can settle...

We present a model of a dynamic and complex economy in which the creation and the destruction of money result from interactions between multiple and heterogeneous agents. In the baseline scenario, we observe the stabilization of the income distribution between wages and profits. We then alter...

Ce papier présente un modèle macroéconomique qui associe étroitement théorie de la monnaie endogène et approche multi-agents. C'est un modèle décentralisé, peuplé d'agents multiples, hétérogènes, autonomes et concurrents qui interagissent simultanément dans les sphères réelle et...

This paper studies the effect of investor's bounded rationality on market dynamics. In an order driven market, we consider a few-types model where two risky assets are exchanged. Agents differ by their behavior, knowledge, risk aversion and investment horizon. The investor's demand is defined by...

This article considers the effects of uncertainty, structure, trust and resistance to change on the success or failure of management accounting innovations diffusion. The diffusion process is examined through a social network of nodes and ties. Ties represent communication channels through which...

In a discrete time option pricing framework, we compare the empirical performance of two pricing methodologies, namely the affine stochastic discount factor (SDF) and the empirical martingale correction methodologies. Using a CAC 40 options dataset, the differences are found to be small: the...

In this paper, we provide a new dynamic asset pricing model for plain vanilla options and we discuss its ability to produce minimum mispricing errors on equity option books. The data set is the daily log returns of the French CAC40 index, on the period January 2, 1988, October 26, 2007. Under...
