Abstract
This paper considers the Bak-Sneppen (BS) Self-Organized Criticality
model originally developed for species co-evolution.We focus both on the original
application of the model on a lattice, and on scale-free networks. Stylized facts
on firms size distribution are also considered for the application of the model to
the analysis of firms size dynamics. Thus, the BS dynamics under the uniform,
Normal, lognormal, Pareto, andWeibull distributions is studied. The original model
is also extended by introducing weights on links connecting species, and examining
the topology of the resulting Minimum Spanning Tree (MST) of the underlying
network. In a system of firms a MST may evidence the template of the strongest
interactions among firms. Conditions that lead to particular configurations of a MST
are investigated.
