  Complex networks have gained much attention from different areas of knowledge
in recent years. Particularly, the structures and dynamics of such systems have
attracted considerable interest. Complex networks may have characteristics of
multifractality. In this study, we analyze fractal and multifractal properties
of a novel network: the large scale economic network of payments of Estonia,
where companies are represented by nodes and the payments done between
companies are represented by links. We present a fractal scaling analysis and
examine the multifractal behavior of this network by using a sandbox algorithm.
Our results indicate the existence of multifractality in this network and
consequently, the existence of multifractality in the Estonian economy. To the
best of our knowledge, this is the first study that analyzes multifractality of
a complex network of payments.
