Abstract
The purpose of the study is to substantiate the potential of using the results of modeling potential GDP and estimating the output gap to comply with fiscal rules that are adequate for the corresponding economic cycle of the economy of Kazakhstan. The methods of economic, statistical, graphical, system, functional analysis, economic and mathematical modeling are applied. To achieve this goal, the analysis of Kazakhstan’s fiscal stability was carried out based on the assessment of Kazakhstan’s potential GDP and the calculation of output gaps, which were carried out based on the dynamic series method of the reported real GDP in 2005 prices for 1991-2019 using the Hodrick-Prescott filter (CP) using the EViews 10 econometric package. The current mechanism for using the output gap indicator in Kazakhstan’s fiscal policy does not have sufficient flexibility. For a timely response of the budget system to changes in the economic situation in the country or abroad, considering the output gap, it is important to introduce an automatic adjustment system that can eliminate contradictions and inconsistencies when making macroeconomic policy decisions by the main regulator and the government of the country. To do this, there is a need to revise the existing fiscal policy based on building a system of new budget rules on countercyclical principles. The proposed alternative fiscal model with the introduction of the rule on the structural balance of the budget is aimed at ensuring long-term fiscal stability, which does not allow for a pro-cyclical policy.
