Socio-economic causes of the long-term repeat of the crisis in the countries of Southeast Europe

The paper critically analyses the basic socio-economic causes of the long-term crisis in the countries of Southeast Europe (SEE). The aim of the paper is to focus on three basic manifestations of post-socialist deviations, which are predominantly related to usurpation and abuses of nomenclatures of power: inherited opportunistic behaviour, quasi-neoliberal experiment, and alternative institutions. Their three-pronged influence causes the crisis, as we have suggested for the initial hypothesis of the study. The paper uses methods of abstraction, description, and analysis (political-economic, institutional, and comparative analysis). The main conclusion is that the phenomena under study were based on underdeveloped quasi-institutional monism. They developed to a great extent and managed to pervade all or almost all social subsystems through the cause-and-effect relationship: social losses - enrichment - impoverishment. The consequences are severe, devastating, and clear. Viewed through this prism, it is clear that the root causes of the crisis can be reduced to the non-existence and/or insufficiency of institutions.
