Entrance into the enclave economy is dependent upon the conditions of incorporation experienced by the individual. Unfavorable modes of incorporation into the host society provide incentives for immigrants to enter the informal economy. Discrimination, hostility and lack of resources may encourage immigrants to enter into informal forms of employment for survival. Ethnic enclaves are rich in informal activities, as the entrepreneurial services making the core of the enclave's founding were historically informal ventures. Informality proves favorable for immigrant entrepreneurships, allowing them to bypass costly regulations. Additionally, the scope of employment for immigrants is greatly widened by the availability of informal jobs in the enclave economic sector.
