Both power law and exponential distributions can be accommodated by it. The demonstration is based on a mathematical structure discovered during a study in gene regulatory network dynamics. Further possible analogy between equilibrium economy and thermodynamics is explored.Latex, 9 pagesPhysics and SocietyData Analysis, Statistics and ProbabilityStatistical Financetext
