“…The majority of studies have found that immigrants tend to concentrate in specific countries (De Giorgi and Pellizzari, 2009;Razin and Wahba, 2015;Agersnap et al, 2020) and regions (Borjas, 1999;Dodson, 2001;Åslund, 2005;Fiva, 2009;Dellinger and Huber, 2021) with generous welfare benefits, consistent with the welfare magnet hypothesis. However, other work has found evidence that immigrants tend to prioritize employment or co-ethnic networks over welfare considerations when selecting residential locations within destination countries (Zavodny, 1999;Kaushal, 2005;Mossaad et al, 2020). This empirical ambiguity can be traced, in part, to issues of data availability and research design.…”
