The costs and benefits of immigration is a hot political topic in Europe and in the US. Migrants, including immigrants and regional in-migrants, are known to make a disproportionate quantitative contribution to new business activity in the UK (Levie, 2007). However, much remains to be discovered about the relative quality of businesses started by immigrants, and this has contributed to a proliferation of theories to explain differences in entrepreneurship by ethnic minority and immigrant status. The study draws on established theories of immigrant and ethnic minority entrepreneurship to develop hypotheses on the propensity of migrants and non-migrants to create high-expectation versus low expectation businesses, innovative versus less innovative businesses, international-focused versus domestic market businesses, and transforming, business services or consumer-oriented businesses for each migrant status.
