    Methodology basis of economic modelling
    (2021) Kotenok, A.
    The paper considers the methodology for modelling economic processes. Economic modelling is the construction of a simplified image of an economic system for studying its properties, forecasting, planning and conducting scenario calculations of the consequences of managerial decisions. The model of the economic system is a reproduction of the interrelated elements of the social and economic environment, the processes of their interaction and functioning, response to environmental changes. Among the main classes of models are econometric, neural network, simulation models, computable general equilibrium models. Each approach is characterized by its own methodology, functionality, purpose. The paper explores the features, advantages and limitations of each approach in terms of modelling economic processes at the micro and macro levels of the economic system. Models of the macroeconomy have gotten quite sophisticated. Such models have also become indispensable tools for monetary policymakers, useful both for forecasting and comparing different policy options. Models in microeconomic theory cover the main models of modern microeconomic theory. The article presents models of an economic agent, abstract models of preferences, choice, and decision making under uncertainty. In general, any activity requires a longer action often characterized by a degree of uncertainty, uncertainty, terms of size of the objective pursued. Because of the complexity of real economic systems, the stochastic dependencies between different variables and parameters considered, not all systems can be adequately represented by a model that can be solved by analytical methods and covering all issues for management decisions analysis-economic horizon real. Often in such cases, it is considered that the simulation technique is the only alternative available.
