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 (106-110 Boulverd de l'Hopital). 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.

Title: On the existence of a pairwise stable weighted network

Abstract: We prove the existence of a pair of Nash equilibrium and pairwise stable weighted network, where payoffs depend on players' strategies and on some endogenous network, the formation of the network itself depending on players' effort for creating links. The existence is given under conditions similar to Nash existence result: quasiconcavity of payoffs (with respect to each link), and continuity. Many applications and relationships with the current literature are given (Jackson-Wolinsky (Jet 1996), Bloch-Dutta (GEB 2009), Bala-Goyal (Econometrica 2000).
