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]
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 ideas developed in the 1990s were put together to develop the new Keynesian dynamic stochastic general equilibrium used to analyze monetary policy. This culminated in the three-equation new Keynesian model found in the survey by Richard Clarida, Jordi Gali, and Mark Gertler in the Journal of Economic Literature.
In a new bottle of soda, the concentration of carbon dioxide in the liquid phase has a particular value. If half of the liquid is poured out and the bottle is sealed, carbon dioxide will leave the liquid phase at an ever-decreasing rate, and the partial pressure of carbon dioxide in the gas phase will increase until equilibrium is reached.
Whereas in a static equilibrium all quantities have unchanging values, in a dynamic equilibrium various quantities may all be growing at the same rate, leaving their ratios unchanging. For example, in the neoclassical growth model , the working population is growing at a rate which is exogenous (determined outside the model, by non-economic ...
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.
The dynamic AD–AS model can be viewed as a simplified version of the more advanced and complex dynamic stochastic general equilibrium (DSGE) models which are state-of-the-art models used by central banks and other organizations to analyze economic fluctuations.
The theory is based on the concept of dynamic equilibrium in which streamforms balance between physical parameters, such as width, depth, velocity, and sediment load, also taking into account biological factors. [2] It offers an introduction to map out biological communities and also an explanation for their sequence in individual sections of ...
