IMPOSSIBILITY OF DECEPTION IN A CONFLICT AMONG SUBJECTS WITH INTERDEPENDENT PREFERENCE

In this paper, we treat strategic information exchange among subjects in a conflict that involves incompleteness of information in terms of subjects' preference and their interdependence. Then, we give two theo rems that indicate senselessness of deceit. One of the theorems implie s that any attempt of a subject to change another subject's preference by deceit will end in failure. The other theorem implies that deceit of a subject causes changes of preference of the subject, thus strateg ic information exchange cannot be effective. (C) Elsevier Science Inc. , 1997
