We test for wage discrimination and occupational crowding in the nineteenthcentury American whaling industry. Although our results indicate little evidence of wage discrimination, we cannot reject the hypothesis that certain groups—specifically blacks and Portuguese–experienced some occupational crowding, though it was by no means complete and the minority-dominated occupations were not low-paying ones. In addition, we find that members of the majority group—white American and Northern European seamen—did accept a negative compensating wage differential for working with members of their own group.
