There is a growing disparity between the salaries that male and female MBA's earn after graduating from business school.  According to a recently released study by Bloomberg BusinessWeek, female MBA graduates are paid 93 cents for every dollar made by their male counterparts.   The gap is even greater for certain industries such as accounting and venture capital, where females make almost 20% less than males in roles with the same job title and rank.  While there are a few industries such as Human Resources and Non-profit where female pay is higher than that of men, in eight out of the eleven industries that were sampled by BusinessWeek, women face a statistically significant wage gap. 
The results are remarkable considering the fact that there is no discernible difference in the quality of male and female job applicants.  Males and females in the top MBA programs scored approximately in the same GMAT percentile and achieved virtually the same grade point averages throughout the business school curriculum.
