Determinants of political stability: explanation of the process of institutional change in post-communist countries (1990-2020)

Abstract

This article examines the institutional changes in 22 post-communist countries during the 1990-2020 period. The objective of the study was to find out why some countries achieved democracy while others failed to establish or strengthen democratic institutions, and what factors influenced the political stability of post-communist countries. During the study, available statistical information on the functioning of the main institutions was collected and processed. The analysis shows that the most significant institutional changes were observed among the non-democratic countries and those that fell into the category of hybrid political regimes. The correction of the initially chosen form of government is evidence in support of the theory of endogenous change, indicating “path-dependency”. The influence of endogenous factors determines the quality of democratic change and the level of political stability in post-communist countries. Democratic changes in the countries of Central and Eastern Europe were associated with a commitment to rapid reform in the early stages, and Euro-Atlantic integration only supported the democratic quality of the institutions. The institutional framework of the countries, that embarked on the path of European integration, was relatively stable during the period under the study, and did not deal with changes in the system of power distribution. While the countries of the former Soviet Union most often resorted to changes in the primary law of the country, and these changes were related to the redistribution of powers between the branches of power and the extension of the time in the office of the President. In addition to the overall level of democratization of the country, the level of emancipatory values and the weight of presidential power have the greatest impact on political stability.
