Using systems engineering software to build a model of the monetary circuit

The Circuitists are a largely European school of economic thought that argue that a monetary economy is fundamentally different to a barter system, and that therefore money cannot be simply modelled as the n+1th good in a Walrasian general equilibrium system. However, while the School has made major contributions to the theory of endogenous money, it has not yet succeeded in constructing a model of the monetary circuit, which is its alternative to general equilibrium modelling. Starting from the first principles by which the School derives its powerful insights into a monetary economy, I construct a simple closed dynamic model of the circuit using systems engineering software (Mathcad). The model's behavior contradicts several propositions previously derived by Circuitists using either equilibrium conditions or unclosed dynamic models
