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 ...
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.
Walras's law is a consequence of finite budgets. If a consumer spends more on good A then they must spend and therefore demand less of good B, reducing B's price. The sum of the values of excess demands across all markets must equal zero, whether or not the economy is in a general equilibrium.
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 ...
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 ...
Robert Solow interprets the theorem as showing that, for modelling macroeconomic growth, the dynamic stochastic general equilibrium is no more microfounded than simpler models such as the Solow–Swan model. As long as a macroeconomic growth model assumes an excess demand function satisfying continuity, homogeneity, and Walras's law, it can be ...
An economic model is a theoretical construct representing economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified, often mathematical , framework designed to illustrate complex processes.
