This not only makes the formulas more concise and clear but also facilitates the use of analytical tools from linear algebra and matrix theory. The John von Neumann's general equilibrium model and the structural equilibrium model are examples of matrix-form CGE models, which can be viewed as generalizations of eigenequations.
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.
SAMs form the backbone of computable general equilibrium (CGE) Models and various types of empirical multiplier models. Appropriately formatted SAMs depict the spending patterns of an economy, as with IMPLAN and RIMS II data, and can be used in economic impact analysis.
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]
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.
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 ...
General equilibrium theory is included in the JEL classification codes as JEL: ... Computable general equilibrium; ... IS–LM model; K.
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.
