We analyze a pure bargaining problem when decisions require simple majority and self interested players make unilateral demands. In contrast to the case where proposals consist of complete sharing profiles, this content of proposals prevents implicit side-payments inside the committee, and so...

It has been empirically shown that structural holes in social networks enable potential large benefits to those individuals who bridge them (Burt, 2004). The work in Goyal and Vega-Redondo (2007) shows that the large payoff differentials caused by structural holes can persist even when agents...

Empirical studies such as Goyal, van der Leij and Moraga (2006) or Newman (2004) show that scientific collaboration networks present a highly unequal and hierarchical distribution of links. This implies that some researchers can be much more active and productive than others and, consequently,...

It has been empirically shown that structural holes in social networks enable potential large benefits to those individuals who bridge them (Burt, 2004). The pioneering paper Goyal and Vega-Redondo (2007) offers a new incentives based explanation of this phenomenon. But the main equilibrium...
