The example of a mixed economy company has a land development fraud neglected by the literature: there is widespread fraud, little by little, the top-down by imitation and addiction, in collusion implied. Literature was more interested, in fact, illegal maneuvers in the eyes of the officer or prohibited by law. But she had not modeled the process by which fraud is formed, grows and finds an end. Based on the case of the SEM, we propose a model for the dissemination of fraud and we discuss its possible generalization, while analyzing the appropriateness of traditional measures of fight against fraud.

This article focuses on current and future analysis teams Socially Responsible Investment (SRI) of asset management in France. The aim of this paper is to investigate a possible convergence between traditional asset management and SRI management, in particular through a detailed study of the tasks performed by these teams and their position in the Management Industry assets. The results of a survey conducted in France in 2009 with key players in the field are presented. These results suggest a convergence taking place between SRI and conventional management (mainstream), although it still seems to be a great heterogeneity of practices reflecting a transition in a field still very fragmented.
