The structural equilibrium model is a matrix-form computable general equilibrium model in new structural economics. [30] [31] 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.
Computable general equilibrium (CGE) models are a class of economic models that use actual economic data to estimate how an economy might react to changes in policy, technology or other external factors. CGE models are also referred to as AGE (applied general equilibrium) models. A CGE model consists of equations describing model variables and ...
Stochastic: The models take into consideration the transmission of random shocks into the economy and the consequent economic fluctuations. General: referring to the entire economy as a whole (within the model) in that price levels and output levels are determined jointly. This is opposed to a partial equilibrium, where price levels are taken ...
Theorem — Let be a positive integer. If : {: =,, >} is a set-valued function with closed graph that satisfies Walras's law, then there exists an economy with households indexed by , with no producers ("pure exchange economy"), and household endowments {} such that each household satisfies all assumptions in the "Assumptions" section except the "strict convexity" assumption, and is the excess ...
See Financial economics § Arbitrage-free pricing and equilibrium. Relatedly, both approaches are consistent [ 9 ] [ 2 ] with what is called the Arrow–Debreu theory . Here models can be derived as a function of " state prices " - contracts that pay one unit of a numeraire (a currency or a commodity) if a particular state occurs at a ...
The classical general equilibrium model aims to describe the economy by aggregating the behavior of individuals and firms. [1] Note that the classical general equilibrium model is unrelated to classical economics , and was instead developed within neoclassical economics beginning in the late 19th century.
In mathematical economics, the Arrow–Debreu model is a theoretical general equilibrium model. It posits that under certain economic assumptions ( convex preferences , perfect competition , and demand independence), there must be a set of prices such that aggregate supplies will equal aggregate demands for every commodity in the economy.
GEMPACK (General Equilibrium Modelling PACKage) is a modeling system for CGE economic models, used at the Centre of Policy Studies (CoPS) in Melbourne, Australia, and sold to other CGE modellers. Some of the more well-known CGE models solved using GEMPACK [ 1 ] are the GTAP model of world trade, and the MONASH, MMRF, ORANI -G and TERM models ...
