Comparative Study of Institutional and Income Convergence of Developing Countries

Why are some countries rich and others poor? And do poor countries converge toward rich countries in terms of economic performance? There are questions that have occupied the minds of economists for a long time, and the answers to these questions are the basis of the formation of economic growth patterns. During the development of developing countries, it is discussed whether institutional and structural homogeneity is a prerequisite for income convergence and performance of developing countries. Our research deals with institutional analysis in developing countries. Therefore, in this research, the formation of institutional and income convergence clusters in developing countries during the period of 2002-2020 has been investigated using the log t test of Phillips and Soule (2007, 2009). The results show that the convergence of institutional indicators among developing countries is rejected. However, the results of the cluster method provide strong evidence of the existence of converging clusters among developing countries. Also, in this study, the clustering of the per capita income of the studied countries has been done, which shows similar results to institutional clustering. which indicates that institutional clusters may be effective in forming income clusters.
