Is there a Double-Negative Effect? Gender and Ethnic Wage Differentials

This paper investigates the gender and ethnic wage differentials for female immigrants, applying the Oaxaca decomposition to estimate the level of discrimination. The gender pay gap is quite small (7.42%), but it's not explained by observable differences, whilst the ethnic wage gap is larger (27.11%), but the explained components account for about 30%. Ultimately, we will evaluate how the multiple levels of discrimination (due to being a woman and a foreigner at the same time) intersect, following the decomposition suggested by Shamsuddin (1998). The double-negative effect is estimated to be 56-62%.
