“…An essential theoretical and simultaneously socio-economic foundation in the empirics of the relationship between migration and socio-economic development is grounded in contemporary international migration theories such as the new economics of labour migration, the push-рull theory, the institutional approach theory, the world systems theory of migration, cumulative causation of migration, relative inequality theory of migration, etc. Their bases are largely supplemented, developed and adjusted to the specifics of current trends and consequences of migration in the studies that provide new methodological approaches to the analysis of the impact of migration on the socio-economic development of a country and its territories (Nyberg-Sorensen, Hear, & Engberg--Pedersen, 2002;Rahman, 2013;Baele, & Sterck, 2015;Basarabă, & Nistor, 2015;Donou-Adonsou, & Lim, 2015;Škuflić, Krpan, & Žmuk, 2018;Kagan, 2019); specify the results of critical (by volumes and negative consequences) migration against the development of human capital (Kuzmin, Bublyk, Shakhno, Korolenko, & Lashkun, 2020;Wielechowski, 2021), falling living standards and quality of life and reducing the wellbeing of households (Shpak, Bublyk, & Rybytska, 2017).…”
