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. A CGE model consists of equations describing model variables and a database usually very detailed consistent with these model equations. The equations tend to be neo-classical in spirit, often assuming cost-minimizing behaviour by producers, average-cost pricing, and household demands based on optimizing behaviour. However, most CGE models conform only loosely to the theoretical general equilibrium paradigm. For example, they may allow for:.

Computable General Equilibrium modelling: a first model

Computable general equilibrium

Studies on Russian Economic Development. Theoretical, empirical, and technical principles of computable general equilibrium models CGE models development have been presented. It is commented how to model the economical processes using this approach. But the resonable criticism of this method is ignored. By analyzing the approaches to CGE models development in the paper it is concluded that the majority of CGE models are not able to describe properly the operation of real economics losing to the method of interindustry forecast. In the recent time the CGE models have been widely used in economics. The presented paper explain why such attractive methods can lose its popularity.

The purpose of this manual is to contribute to and facilitate the use of computable general equilibrium CGE models in the analysis of issues related to food policy in developing countries. Over the past decade, the increasing power and reliability of microcomputers and the development of sophisticated software designed specifically for use with them has led to significant changes in the way quantitative food policy analysis is conducted. These changes cover most aspects of the analysis, ranging from the collections and analysis of socioeconomic data to the conduct of model-based policy simulations… As with any new technology, however, substantial costs in time and money are involved in learning the most efficient ways of using this new technology and then transmitting these lessons to others. The series is designed to provide hands-on methods for quantities food policy analysis…. The purpose of the fifth volume in the series…. The model is written for application at the country level; however, only minimal changes are needed before it can be applied to a region within a country such as a village or to a farm household involved in production and consumption activities.

CGE models are large numerical models which combine economic theory with real economic data in order to derive computationally the impacts of policies or shocks in the economy. CGE models fit economic data to a set of equations which aim to capture the structure of the economy and behavioural response of agents firms, households, government. This provides a framework to simulate policy changes and trace the impact on key economic variables, including income and expenditure flows. The economic impact of the policy or economic shock being modelled is estimated by comparing the economy before and after the shock, as illustrated in the diagram below. The pre-policy baseline is generated by fitting the model equations and the behavioural parameters to the base year data.
