This model is an extension of the [[John von Neumann]]'s general equilibrium model (see [[Computable general equilibrium]] for details). Its computation can be performed using the R package GE. <ref>{{Cite web |url=https://cran.r-project.org/web/packages/GE/index.html |title= CRAN: Package GE |website= The Comprehensive R Archive Network |access-date=2024-12-08}}</ref>
The structural equilibrium model can be used for intertemporal equilibrium analysis, where time is treated as a label that differentiates between types of commodities and firms, meaning commodities are distinguished by when they are delivered and firms are distinguished by when they produce. The model can include factors such as taxes, money, endogenous production functions, and endogenous institutions, etc. The structural equilibrium model can include excess tax burdens, meaning that the equilibrium in the model may not be Pareto optimal. When production functions and/or economic institutions are treated as endogenous variables, the general equilibrium is referred to as structural equilibrium.
