The current state of research of the content, forms, tools and mechanisms of introducing unconditional basic income

The Object of the Study is the definition of the UBI, concept, content, forms, tools and mechanisms, properties and characteristics of unconditional basic incomeThe Subject of the Study is the concept of unconditional basic income in the works of foreign and Russian scientists and researchers from the 16th century to the present dayThe Purpose of the Study is analyzing the state of research in the field of UBI, study the results of existing simulation experiments, systematize the available disparate information. Identify fields requiring further research. Conduct a statistical analysis of the frequency of use of the term UBI in the scientific literature, build«word clouds» of scientific articles on UBI.The Main Provisions of the Article. The article provides a detailed review and classification of studies on the subject of unconditional basic income (UBI); its content, forms, tools and mechanisms of administration; UBI is compared with similar forms of social support. The author considers both the works of classical authors and contemporary works, where the effects of introducing UBI using simulation methods are studied. The UBI studies of leading world financial and research organizations (OECD, World Bank, IMF) are analyzed. A review of modern Russian studies on the topic of UBI is conducted. We identified problem fields requiring further investigation and areas with great research potential.«Word clouds» were created and a frequency analysis of mentions of terms related to the UBI was carried out. The article consists of the following sections: 1) Introduction; 2) UBI research history;Contribution of Russian scientists to the development of UBI issues; 4) Simulations of the introduction of UBI; 5) Statistical analysis of citation and text analysis; 6) Conclusions.
