Identity and Fragmentation in Networks

Author

  • Dev, Pritha

Abstract

This paper looks at the role of identity in the fragmentation of networks by incorporating the choice of commitment to identity characteristics, into a noncooperative network formation game. The Nash network will feature divisions based on identity, moreover, it will have layers of such divisions. Using the renement of strictness, I get stars of highly committed players linked together by less committed players. Next, I propose an empirical methodology to deduce which dimensions of identity cause the fragmentation of a given network. I propose a practical algorithm for the estimation and apply this to data from villages in Ghana.
