This event was organized jointly by faculty members of three French academic institutions a"" ENSAE ParisTech, the Ecole Polytechnique ParisTech, and HEC Paris a"" which cooperate through a scientific foundation devoted to the decision sciences. The scientific content of the summer school was conveyed in two courses, one by Laurent Cavalier (Universite Aix-Marseille I) on ""Ill-posed Inverse Problems"", and one by Victor Chernozhukov (Ma
