Search in the Formation of Large Networks: How Random are Socially Generated Networks?
Jackson, Matthew O.; Rogers, Brian W. - EconWPA - 2005
features that have been found to characterize large socially generated networks. Moreover, we derive the distribution of degree … lower tail may exhibit substantial curvature, just as in observed networks. We then fit the model to data from six networks …. Besides offering a close fit of these diverse networks, the model allows us to impute the relative importance of search versus …

A Survey of Models of Network Formation: Stability and Efficiency
Jackson, Matthew O. - EconWPA - 2003
I survey the recent literature on the formation of networks. I provide definitions of network games, a number of …

The Economics of Small Worlds
Jackson, Matthew O.; Rogers, Brian W. - EconWPA - 2005
We examine a simple economic model of network formation where agents benefit from indirect relationships. We show that small-world features - -- short path lengths between nodes together with highly clustered link structures --- necessarily emerge for a wide set of parameters.

Social Games: Matching and the Play of Finitely Repeated Games
Jackson, Matthew O.; Watts, Alison - EconWPA - 2005
We examine a new class of games, which we call social games, where players not only choose strategies but also choose with whom they play. A group of players who are dissatisfied with the play of their current partners can join together and play a new equilibrium. This imposes new refinements on...

Quantum Solution of Coordination Problems
Huberman, Bernardo A.; Laboratories, Tad Hogg HP - EconWPA - 2003
We present a quantum solution to coordination problems that can be implemented with present technologies. It provides an alternative to existing approaches, which rely on explicit communication, prior commitment or trusted third parties. This quantum mechanism applies to a variety of scenarios...

Additive rules in bankruptcy problems and other related problems
Bergantiños, Gustavo; Vidal-Puga, Juan - EconWPA - 2003
In this paper we characterize the set of rules satisfying additivity on the estate along with additivity on the estate and the claims in bankruptcy problems and other related problems. Moreover, new characterizations of the well known rules based on the principles of "equal award", "equal loss",...

The NTU consistent coalitional value
Bergantiños, Gustavo; Vidal-Puga, Juan - EconWPA - 2003
We introduce a new value for NTU games with coalition structure. This value coincides with the consistent value for trivial coalition structures, and with the Owen value for TU games with coalition structure. Furthermore, we present two characterizations: the first one using a consistency...
