Purpose and subject of research We consider linear and nonlinear models of business behavior under external pulse investments to basic production assets of enterprises. Research methodology In the article used methods and models of decision making, mathematical models of the dynamics, evolutionary models with implicit and degenerate differential equations. Value results The article investigates the linear and nonlinear dynamics model production with external impulse investment in fixed assets of enterprises. Analyzed deceleration and acceleration rates of output growth, the effects of stabilization of fixed assets, investment optimization dynamics pulsed with quadratic performance. Conclusions Obtained formulas of overall production and basic assets contain jumps at moments of investment earnings. We analyze the deceleration and acceleration of business growth, the stabilization of basic assets, the optimization of dynamics of pulse investments with quadratic cost function.

Purpose and subject of research For the modern economic model the transformation of the tradition monetary transmission mechanism is relevant that demands in-depth analysis of the effectiveness of the monetary channels and the determination of the optimal structure of the transmission mechanism especially for the developing countries. The integrated assessment of the changes in the Ukrainian monetary transmission mechanism, in-depth analysis of the effectiveness of the separate channels and the investigation of the peculiarity of the impulses transmission by the exchange rate channel in short run and long run for Ukrainian economy is the main object of this study. Research methodology A theoretical and empirical framework is proposed based on the monetary theory, including the new features of the monetary transmission mechanism and the time series analysis with vector error correction models. Value results The statistical analysis, analysis of the impulse responsible functions and the variance decomposition on the base of the elaborated vector error correction model for the exchange rate channel had allowed to estimate its influence on the real sector of the Ukrainian economy in short run and long run and empirically improve the hypotheses about special feature of this channel for Ukraine. The present study provides a starting-point for further research in the effectiveness of the transmission mechanism channels for the developed and developing countries for the purpose of the determination of the effective directions of the monetary policy for the stimulation of the economic growth. Conclusions The framework has proven to be useful to show the specific and the dominant role of the exchange rate channel for the Ukrainian economy and nonsignificant function of the other channels for the Ukraine which demands not only of the improvement of the exchange rate policy but also the transformation of the structure of the Ukrainian monetary transmission mechanism.

Purpose and subject of research The purpose of research is the development of methodical approach to determining the level of economic stability on the basis of industrial building system of integrated indicators. Research methodology A theoretical framework is based on methods of system analysis in management of the insurance company development, innovative control methods. Value results The paper examines the economic sustainability of the enterprise from the perspective of the functional stability characteristics (parameters), highlights various components of sustainability: financial, technological, organizational, commercial and social. It is proposed to evaluate the stability of the economic system using the stability of indexes and the balanced proportions of the enterprise developing. Conclusions The proposed assessment of the economic viability is viewed from the perspective of sustainability components. Within the range of the components, elements that characterize the use performance of their potential, should be provided. The methodical approach of constructing a system of integrated indicators for each of these types of resistance, makes it possible to carry out a comprehensive assessment of the industrial enterprise's economic viability, and identify an approaching to the bifurcation point.

Purpose and subject of research The purpose of research is to systematize the management methodology enterprise's competitiveness for unstable economic environment. Research methodology In the article expert analysis methods, optimization and simulation modeling were used for solving the problem. Value results Instability limits were identified and formalized in the research. The study is based on the new definition of enterprise's competitiveness, which is determined by the preferences degree of the enterprise. This approach is allowed to develop the comprehensive approach to competitiveness control, with using of economicmathematical modeling. Conclusions Theoretical and methodological substantiation of using new enterprises' management models and methods for unstable economic environment were proposed in the article. In this methodology is indicated an application of developed complex models for enterprises that operating in unstable economic environment.

Purpose and subject of research The aim of this paper is to identify the essential system characteristics of financial market and methodological development of algorithm, which is used for behavior of market price’s forecast modeling. Research methodology A theoretical framework is proposed investigation of the financial market’s essential characteristics as a complex socio-economic system. Subsequently described system attributes, which can be measured quantitatively, it is proposed to use for the analysis and prediction of the price’s behavior in the financial market. It is proposed algorithm for researching of financial markets as complex systems that use the system complexity’s attributes. Value results The present study provides a starting-point for further research of complexity’s attributes in the financial markets. Conclusions The proposed algorithm not only makes the process of financial market research correctly, but can be used for other socio-economic systems after some adaptation.
