Dynamic stochastic general equilibrium modeling (abbreviated as DSGE, or DGE, or sometimes SDGE) is a macroeconomic method which is often employed by monetary and fiscal authorities for policy analysis, explaining historical time-series data, as well as future forecasting purposes. [1]
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 ...

A macroeconomic model is an analytical tool designed to describe the operation of the problems of economy of a country or a region. These models are usually designed to examine the comparative statics and dynamics of aggregate quantities such as the total amount of goods and services produced, total income earned, the level of employment of productive resources, and the level of prices.
Dynamic macroeconomics makes heavy use of Markov chains. An example is using Markov chains to exogenously model prices of equity (stock) in a general equilibrium setting. [100] Credit rating agencies produce annual tables of the transition probabilities for bonds of different credit ratings. [101]
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 ...
Input–output accounts are part and parcel to a more flexible form of modelling, computable general equilibrium models [a]. Two additional difficulties are of interest in transportation work. There is the question of substituting one input for another, and there is the question about the stability of coefficients as production increases or ...
