Language and urban labor market segmentation: Theory and evidence

I propose a language theory of labor market segmentation. People of different language origins form separate urban labor submarkets and can switch between submarkets. Two types of wage differentials emerge, namely the Within-Labor-Market Wage Gap and the Within-Language-Group Wage Gap. The average wage in each market and a worker’s choice of the labor market depend on the population sizes of the relevant groups. These implications are tested using the 2001 Census of Canada Public Use Microdata. A unique feature of these data is the reported work language, which helps me to identify labor market segments. The empirical evidence supports my theory.
