Uniqueness of the efficiency functional for deriving the Zipf and the Pareto laws from the principle of least effort
Résumé
In a previous work, we applied the principle of least effort to derive the Zipf and the Pareto power law distributions using a calculus of variation and an efficiency functional. This functional was arrived at by considering living systems containing a great number of agents all trying to achieve something with effort, similarly to thermal engines producing work from source energy, and a nonadditive relationship of efficiency in thermodynamics. In the present work, we provide a complete proof of the uniqueness of this efficiency functional, thus confirms the intrinsic link between the power laws and the principle of least effort.
