Dadashova P. System analysis and modelling of the fiscal and monetary policy mutual consistency impact on macroeconomic stability

In the dissertation, a complex of dynamic macro models of the Ukrainian economy, which consists of vector autoregression models, models of simultaneous equations system with error correction mechanism, and imitational system dynamics model, is developed in order to evaluate the impact of the mutually consistent fiscal and monetary policy on macroeconomic stability. In the research, the theoretical definition of the macroeconomic stability is substantiated and the list of its indicators in long term perspective is presented. The developed complex of dynamic macro models includes vector autoregressive models for the assessment of the main channels of the direct interaction between fiscal and monetary sectors and broad diagnostics of the transmission mechanism of the monetary policy power. Based on the obtained results, two macro models of the Ukrainian economy are proposed: a dynamic system of simultaneous equations with error correction mechanism and a system dynamics model. Based on the obtained research results, the economy destabilization risks map has been built to be applied in the governmental policy implementation aimed at achieving macroeconomics stability. The macro models realization allows for a detailed scenario analysis to determine any potential threats of economy destabilization and efficient measures in order to achieve macroeconomic stability.
