Abstract
In this thesis, we reexamine the Coauthors’ Problem, introduced by Jackson
and Wolinsky, 1996. We propose the Extended Coauthor Model using the
cover notion, allowing for multilateral links among authors. We study the
model under two utility functions, which are the extreme members of the class
of utility functions induced by different synergy terms. We find the structure
of the efficient and the link-wise stable covers formed under different utility
functions, which depend on the synergy term under consideration. Moreover
we introduce the core and core stability concepts for covers and investigate the
properties possessed by core-stable covers. We find the relationship between
the allocation induced by core-stable covers and the allocations in core, under
player based flexible allocation rule. Finally we investigate the endogenous
cover formation via a strategic form game, called the hyper-link formation
game. We define Nash stability and Strong Nash stability for covers and
study the characteristics of such covers.
