Studies found that the percentage of women among those graduating with master's degrees in business rose dramatically from 3.9% in 1971 to 37% in 1995. In the fall of 1992, however, The Wall Street Journal reported on what appeared to be a change in that trend. According to an article in the September 25, 1992, issue (p. B1), women as a percentage of entering Master of Business Administration (M.B.A.) classes had fallen substantially at many top schools after peaking in the 1980s. A career counsellor interviewed in the article said the changes occurred because "a lot of women who were the pioneers in M.B.A. programs and big companies rushed blindly into what were formerly forbidden areas. . . . Now, a lot of these women have come back and told their younger sisters, 'It's not that great out there'." Using the human capital approach, assess the reasonableness of this explanation
