A Natural Value Unit - Econophysics as Arbiter between Finance and Economics

, 2006
Foreign exchange markets show that currency units (= accounting or nominal price units) are variables. Technical and economic progress evidence that the consumer baskets (= purchasing power units or real price units) are also variables.
