Stressing the network's facilitation of immigrants' searches for jobs and h
ousing, migration network theory has conceptually overlooked the social net
works also expand the supply of jobs and housing in target destinations by
means of the ethnic economy. An expanded migration network theory takes int
o account the ethnic economy's role in creating new resources in the destin
ation economy. However, the power of this objection wanes in the context of
working-class immigrations that generate few entrepreneurs. Introduced her
e, the concept of immigrant economy responds to this contingency. Unlike et
hnic economies, in which co-ethnics hire co-ethnics, immigrant economies ar
ise when immigrants hire non-co-ethnic fellow immigrants. This situation us
ually arises when very entrepreneurial immigrant groups coexist in a labor
market with working-class immigrant groups that generate few entrepreneurs
of their own. Using evidence from the garment industry of Los Angeles, this
paper estimates that only a third of immigrant employees found their jobs
in a conventional ethnic economy. Half owed their employment to the immigra
nt economy in which, for the most part, Asian entrepreneurs employed Latino
workers.
