We consider returned emigrants as a potentially neglected entrepreneurial resource, using data from the United Kingdom as an example. We use structuration theory (Giddens, 1984) to propose that a move from a home to host context and back again may prompt returned emigrants to identify and act on opportunities as an act of reflexive self-regulation. We use the Global Entrepreneurship Monitor United Kingdom 2013 to 2017 adult population surveys, with 48,011 GEM respondents. Returned emigrants have relatively high opportunity identification prevalence and early-stage entrepreneurship prevalence.
