CES Economic Theory Seminar

Home 

The Economic Theory workshop is a weekly seminar taking place on fridays 12-13h at the Maison des Sciences Economiques (106-112 Boulevard de l'Hôpital). This seminar is a venue for theoretical work in Economics and for work drawing on quantitative methods in Economics. Defined by an approach rather than by a specific theme, the topics of the seminar can concern a variety of areas in Economics, such as (non exhaustively), micro economics, game theory, mathematical economics, decisions theory, finance or macro economics. The seminar functions as an internal workshop but also regularly greets speakers from other institutions.

Organizers: Emily Tanimura, Stéphane Zuber, Anna Bogomolnaia and Hervé Moulin,

It is supported by the Centre d'économie de la Sorbonne, CNRS and Université Paris 1 Panthéon-Sorbonne.

Title:   Do You Know What I mean? A Syntactic Representation for Differential Bounded Awareness

Location: Maison des Sciences Économiques, room S17 

Summary:  Without an assumption of complete shared awareness, it becomes necessary to consider communication between agents who may have different representations of the world. We take a syntactic (language-based) approach and ask whether, given an appropriate translation, agents can understand each other. We define translation operators between two languages which provide a ”best approximation” of meaning, subject to its expressive power. We derive necessary and sufficient conditions for the existence of a joint state space and a joint language, in which the subjective state spaces and the individual languages may be embedded.

Title :   Collective State Spaces

Location: Maison des Sciences Économiques, room S17. 

Summary:  This paper examines how a society should construct a comprehensive state space from individuals’ distinct state spaces in the absence of an exogenously specified state space. We show that the social state space must coincide with the Cartesian product of individual state spaces. Our characterization is based on four normative axioms, three of which are weak Pareto-type conditions designed to rule out spurious unanimity that can arise from preferences over menus.
