The fluctuation-dissipation theorem connects the two to establish a concrete correspondence of "temperature", "entropy", "free potential/energy", and other physics notions to an economics system. The statistical mechanics model is not constructed a-priori - it is a result of a boundedly rational assumption and modeling on existing neoclassical models. It has been used to prove the "inevitability of collusion" result of [[Huw Dixon]] in a case for which the neoclassical version of the model does not predict collusion.<ref name="HD">{{cite journal | last = Dixon | first = Huw| title = keeping up with the Joneses: competition and the evolution of collusion| journal = Journal of Economic Behavior and Organization| volume = 43| issue = 2| pages = 223–238| date = 2000| doi=10.1016/s0167-2681(00)00117-7}}</ref> | The fluctuation-dissipation theorem connects the two to establish a concrete correspondence of "temperature", "entropy", "free potential/energy", and other physics notions to an economics system.
