- Abstract: This paper reviews and analyzes the emerging
network paradigm in organizational research. It begins with a conventional
review of recent research organized around recognized research streams. It
then analyzes this research, developing a set of dimensions along which
network studies vary, including: direction of causality; levels of analysis,
explanatory goals, and explanatory mechanisms. The latter is used to
construct a 2-by-2 table cross-classifying studies of network consequences
into four canonical types. The paper concludes by noting the rising
popularity of studies placing a greater stress on agency than was traditional
in network research.

Bernd Fritzke, Growing Self-Organizing Networks - Why?"
In: M. Verleysen, (ed.), ESANN'96: European
Symposium on Artificial Neural Networks, D-Facto Publishers,
Brussels, 1996, 61-72 (invited paper).
"The reasons to use growing self-organizing networks are
investigated. First an overview of several models of this kind is given
are they are related to other approaches. Then two examples are pre-
sented to illustrate the specic properties and advantages of incremental
networks. In each case a non-incremental model is used for comparison
purposes. The rst example is pattern classication and compares the
supervised growing neural gas model to a conventional radial basis func-
tion approach. The second example is data visualization and contrasts
the growing grid model and the self-organizing feature map."
- Sanjeev Goyal (Faculty of Economics, Cambridge University, UKB),
"Learning in Networks"
Working Paper, December 2003.
- Abstract: This paper surveys theoretical (analytical)
research on learning, with a special focus on the interaction network between
individual entities. The survey first examines the nature of learning about
optimal actions for a given network architecture. It then discusses learning
about optimal links and actions in an evolving network.
- Sanjeev Goyal, Connections: An Introduction to the Economics of Networks, Princeton University Press, Princeton and Oxford, 2007.
- Abstract: In (this booKB), Sanjeev Goyal puts contemporary thinking about networks and economic activity into context. He develops a general framework within which this body of research can be located. Topics covered include: network concepts and empirics; games on networks; coordination and cooperation; social learning; social networks in labor markets; strategic network formation; one-sided link formation; two-sided link formation; and research collaboration among firms.
- Matthew Jackson (Cal Tech, Pasadena), "A Survey of Models of Network
Formation: Stability and Efficiency"
Working Paper, Revised May 2003.
- Abstract: This study is an extensive survey of the
theoretical (analytical) literature on the formation of non-directed
networks, i.e., networks in which links require mutual consent. Jackson
notes in conclusion that many important and interesting open questions
remain, many going well beyond what can currently be handled by analytical
methods. He briefly mentions recent empirical research on network formation,
as well as recent experimental research with human subjects and with
- Michael Kosfeld (University of Zurich, Switzerland),
Working Paper, May 2003.
- Abstract: This paper surveys (human-subject) experimental research on social and economic
networks. The experiments consider networks of coordination and cooperation,
buyer-seller networks, and network formation.
David G. Rand, Samuel Arbesman, and Nicholas A. Christakis, "Dynamic Social Networks Promote Cooperation in Experiments with Humans
Proceedings of the National Academy of Sciences, Early Edition, 2011.
- Abstract:The authors conduct human-subject experiments to explore large-scale cooperation, where subjects' cooperative actions are equally beneficial to all those with whom they interact. Their experimental findings confirm the predictions of a set of evolutionary game theoretic models and demonstrate the important role that dynamic social networks can play in supporting large-scale human cooperation.

Science, 24 July 2009, Vol. 325, No. 5939, pp. 422-425.
"The current economic crisis illustrates a critical need for new and fundamental understanding of the
structure and dynamics of economic networks. Economic systems are increasingly built on
interdependencies, implemented through trans-national credit and investment networks, trade relations, or
supply chains that have proven difficult to predict and control. We need, therefore, an approach that
stresses the systemic complexity of economic networks and that can be used to revise and extend
established paradigms in economic theory. This will facilitate the design of policies that reduce conflicts
between individual interests and global efficiency, as well as reduce the risk of global failure by making
economic networks more robust."

An Elucidative Framework and Survey of Results", Macroeconomic
Dynamics 7(3), 2003, 424-472.
- Abstract: The author presents an analytical framework for exploring the
implications of economic interaction. The initial sections of the paper
include a survey of previous work on interacting agent economies with a
stress on analytical studies.

- Chris Cook (Computer Science Department, Iowa State University,
Ames) has developed an interactive computer demo for an extended version of
the Schelling Segregation Model (SSMB), due to Thomas Schelling
(Micromotives and Macrobehavior, Norton, 1978). Agents are located on
a chess board with 64 locations. The user determines the population mix from
among three agent types (red, green, and blue), or chooses from among various
default settings. The user can also specify a "happiness rule" for
each agent type or select a default setting. The happiness rule determines
when an agent is happy with his current board location, taking into account
both the number and the types of his neighbors. If unhappy, the agent either
attempts to move to a more desirable board location or exits the board

- Trade Network Game Lab (Tesfatsion)
- The Trade Network Game Laboratory (TNG Lab) is a
computational laboratory for exploring the evolution of trade networks among
strategically interacting buyers, sellers, and dealers. The TNG Lab is
targeted for the Microsoft Windows desktop and is both modular and
extensible. It permits visualization of the formation and evolution of trade
networks by means of run-time animations, run-time charts, and run-time data
displays. A clear, easily operated graphical user interface permits testing
of key parameters pertaining to learning, payoffs, types and numbers of
agents, and the physics controlling network displays. Automatic installation
software for the TNG Lab, together with tutorials and research articles, can
be obtained at the
TNG Home Page.
