Оценка конвергенции экономического роста в странах ЕАЭС
The article outlines methodological approaches to measuring the level of convergence in the Eurasian Economic Union (EEU) countries. The authors introduce the concept of conditional cyclical convergence of national economies as a convergence of short-term growth cycles in the overall macroeconomic dynamics. Decomposition of the cyclical macroeconomic dynamics in the countries is performed through the identifying a long-term sustainable profile and short-term growth cycles. For this purpose, the double-pass through the Hodrick-Prescott statistical filter is applied for the original time series. Identified short-term growth cycles are visualized for each country using tracers of cyclic profiles. The conditional convergence of economies is determined on the basis of statistically significant cross-correlation coefficients. The results of the calculations also make it possible to estimate the degree of synchronism in short-term growth cycles in the dynamics of the gross domestic product (GDP) index, the stable trajectories of the countries economic development, and draw a number of conclusions, in particular, to assess the slowdown in long-term macroeconomic growth in recent years and the growth volatility. A distinctive feature of recent convergence in the economic integration is not the gaps reduction between the countries potentials, but the convergence of short-term growth cycles in the macroeconomic development. The growth slowdown in the Russian economy did not contribute to the positive prospects in the EEA countries. The strongest correlation in the analyzed period describing over 90% of the entire variation in time series was observed in the short-term GDP growth profiles in Russia, Kazakhstan, and Belarus. Based on the calculations performed, the conclusions are drawn about the large-scale slowdown of long-term stable profiles in the dynamics of macroeconomic growth in all countries of the integration, the noticeable volatility of growth, almost simultaneously observed two years of recession with a clear predominance of major crisis events in 2015.
