Approaching preference change by partial deliberation

Abstract : This Ph.D. dissertation aims at providing new conceptual and formal tools in order to model preference changes. To do so, I model a mechanism that I refer to as partial deliberation. Partial deliberation is based on the idea that individuals change their preference by becoming aware of new values. Indeed, their awareness allows them either to reject values they were adhering to or to adopt new values. By critically analysis of the literature on preference changes and on rational choice theory, the introduction emphasizes the main philosophical issues of partial deliberation. The first chapter justifies the five psychological hypotheses on which this mechanism relies and discusses their relation with rational choice theory. The second chapter axiomatically deals with partial deliberation and it formalizes two specific structures : a monotonic structure and partitional structure.Then, the third chapter models a situation of preference manipulation, in which a sender jointly chooses a project and a disclosure strategy in order to manipulate the preference of a receiver. With this model, I account for imperfect empathy and sequential disclosure of values.
