Many real networks are said to be ¸ Sscale-freeˇT since they show a power law behavior. In this paper, we focus in self-similarity of economical phenomena. For that purpose we analyze data and their corresponding statistical properties. We approximate data by trendlines, whose parameters are unequivocally related with each type of phenomenon.engconference object10.3182/20120215-3-AT-3016.00103
