Inspection of the country databases of exported products shows that this is not the case: successful countries are extremely diversified, in analogy with biosystems evolving in a competitive dynamical environment. The challenge is assessing quantitatively the non-monetary competitive advantage of diversification which represents the hidden potential for development and growth. Here we develop a new statistical approach based on coupled non-linear maps, whose fixed point defines a new metrics for the country Fitness and product Complexity. We show that a non-linear iteration is necessary to bound the complexity of products by the fitness of the less competitive countries exporting them. We show that, given the paradigm of economic complexity, the correct and simplest approach to measure the competitiveness of countries is the one presented in this work. Furthermore our metrics appears to be economically well-grounded. date: 2012-10 date_type: published publication: Scientific Reports volume: 2 publisher: Nature Publishing Group id_number: 10.1038/srep00723 refereed: TRUE issn: 2045-2322 official_url: http://dx.doi.org/10.1038/srep00723 projects: EC FET Open Project “FOC” No. 255987 projects: PNR project CRISIS-Lab citation: Tacchella, Andrea and Cristelli, Matthieu and Caldarelli, Guido and Gabrielli, Andrea and Pietronero, Luciano A New Metrics for Countries' Fitness and Products' Complexity.
