Monetary System

The tenjinMacro monetary system model is actually a computational (agent-based) interpretation of ModelSIM - the simplest sectoral balances model with government money - created by the late, great, Wynne Godley and Marc Lavoie (G&L). ModelSIM and other more sophisticated models are described in their book, 'Monetary Economics: An Integrated Approach to Credit, Money, Income, Production and Wealth'.

Agent-based models must expedite:

  • Integration of economic time-series aggregates.
  • Display path dependence, in that exogenous variables become endogenous variables.

Models will solve computationally; not as systems of equations. Models must remain consistent with stock-flow accounting. Sectoral agents (best described as partially understood metaphors) are bound by monetary system stocks and flows.

Framework misunderstanding and agent-based model errors are the developer's responsibility alone.
