In this article the authorsw review several different concepts related to immigrant incorporation in the labour market through self-employment. They also examine the main theoretical currents concerned with explaining the phenomenon, occasionally with particular attention to cultural, ecological and interactive factors typical of the North American environment. However, the European case requires a new model, based on social embedment, analysing both market determinants and context of reception, which are usually stricter. Finally, they go on to the new perspectives of research that understands consolidation of immigrant entrepreneurs as a logical transnational action.
