Gender Wage Gap
The folks at learnstuff.com have sent me an infographic on the gender wage gap in the United States (click here). The puzzle is this: although women achieve higher scores in college than their male peers, women earn less than men. This holds true across all levels of education. Why? Discrimination may be part of the story, but child-rearing may explain a large chunk of the gap. A neat study would be to look at the effect of child-rearing on the wage gap. In other words, does the wage gap exist for childless women? If so, the puzzle deepens.
