Employer Attitudes, the Marginal Employer, and the Ethnic Wage Gap [PDF]
ILR Review, 2011 In most EU countries, ethnic minorities have lower wages than does the ethnic majority. To what extent these wage gaps are the result of prejudice toward ethnic minority workers is virtually unknown. The authors examine the role that prejudice plays in the creation of the ethnic wage gap in one of Europe’s most egalitarian countries, Sweden.
