Overview
In the econophysics literature, Marshall is oft cited has having employed remote thermodynamic stylized thinking in his economics theories, e.g. the notion that economies achieves an equilibrium state like that described for gases by James Maxwell and Ludwig Boltzmann; or to have used the conservation of energy or the first law in his utility theories. [1] Most of these physics plus economics connections and assertions, however, seem rather tenuous and a stretch, as compared to other economic thermodynamicists.
