Optimum Trajectory of Dynamic Input-Output Balance Model for Open Economy

When export and import is connected with output of basic production, and criterion functional represents a final state of economy, the generalization of classical qualitative results of the main-line theory on a case of dynamic input-output balance optimization model for open economy is given

Statistical analysis of self-similar behaviour in the shear induced melting model

The analysis of the system behavior under the effect of the additive noises has been done using a simple model of shear melting. The situation with low intensity of the order parameter noise has been investigated in detail, and time dependence of the order parameter has been calculated. A distinctive feature of the obtained dependence is power-law distribution and self-similarity. The generalized Hurst exponent of the time series has been found within multifractal detrended fluctuation analysis. It is shown that the self-similarity of the time series increases when the noise intensity reduces.Comment: 11 pages, 9 figures, 29 reference

Inter-branch models of multi-structural economy Межотраслевые балансовые модели многоукладной экономики

The article offers static and dynamic inter-branch models of a multi-structural closed economy, which use an inter-branch approach within the framework of each technological structure. Methods of aggregation and optimisation are used for static models. The main-line approach is realised for dynamic models.В работе предложены статические и динамические межотраслевые модели многоукладной закрытой экономики, использующие межотраслевой подход в рамках каждого технологического уклада. Для статических моделей используются методы агрегирования и оптимизации. Для динамических моделей реализуется магистральный подход
