Dear Carl
We are people from Economics and the model we developed is a theoretical one
based on Game Theory framework. More specifically based on
Bala, V. and S. Goyal (2000). "A noncooperative model of network formation."
Econometrica 68(5): 1181-1229.
Our variable is information flow (in abstract sense) and the actors are
rational agents that maximized the information they receive considering
costs of connection. It's not a structural (sociological) approach paper but
a model based on economic assumptions. We looked for Nash equilibria,
optimal topologies, and the like.
Full graph it's not optimal because of the redundant links that this
structure posses and because we made the assumptions that agents cannot deny
connection when required for others agents. There's some sort of
hierarchical structure underlying the analysis. It is more an analytical
exercise than a real-based social network research, but we looked for
potential real examples where this structure could emerge.
Thanks for the question and the comments
Sincerely Yours
Juan

Juan,
Very interesting that you came to the conclusion that a one-dimensional
closed-space structure is the most optimal. Some thoughts though:
What is the structural variable in your model?
What exactly is optimized in the model?
Shouldn't a full graph, i.e where all actors are connected to eachother, be
the most optimal structure (at least from a neoclassical point of view)?
Yours,
Carl

Colleagues:
I have developed with a colleague of mine an economic model of network
formation. Results gave us circular network architecture as optimal
structure. It means that individual are full connected but in row where the
last one individual must be connected with the first one. A quite simple
example could be this:
A
/ \
/ \
/ \
B-------C
I've read sociological literature where this structure could be assimilated
to a clique network, but I'm suspicious about other potential implications
in social networks research. Does anyone remember another social network
architecture (with real examples) where this circle form could emerge?
Specific references are welcome...
Thanks in advance,
Juan
