This paper compares the influence of gender and ethnicity on wage discrimination in Guatemala using the 2000 Living Standards Measurement Survey. The sample of employees is divided into six ethnic-gender groups: males and females in three ethnic groups (i.e., non-indigenous, major and minor ethnic groups). Normalized regressions are used to estimate wage structures for each ethnic gender group including the inverse of Mill's ratio as a regressor to correct for potential selectivity. Then, the contribution of gender and ethnic discrimination on wage differentials is examined. Findings indicate that, compared to ethnic discrimination, gender discrimination explains a more significant percentage of wage differentials between relevant groups. Additionally, results indicate that forms of wage discrimination differ across ethnic-gender groups.
