Abstract

We represent an exchange economy in terms of statistical ensembles for complex networks by introducing the concept of market configuration. In this way, starting from economic reasoning, we obtain a sound interpretation of the typical network variables in terms of thermodynamic quantities together with a strong consistency with microeconomic theory, and in particular with Walrasian general equilibrium theory. In our formalism, naturally arises the interpretation of the temperature T as a quantification of economic disequilibrium, which can indeed coexist with statistical equilibrium.
