Passage Four
Women earn less than men do. For example, in 1998 the hourly wages of women in the U. S. were 26% less than those of men.
The gap between male and female incomes varies with age. The gap between the labor incomes of young women and young men
varies. It’s also clear that jobs in which women are concentrated pay less. The larger the number of workers who are women in ran
industry, the lower the average wages.
Why do women earn less than men do? Can the differences be explained by the fact that women are looked
down upon? If so, the government has to intervene(干预), to force the employers to pay equal wages to equal jobs. However, there is no agreement among economists about the causes of
the gap. One view argues that women, on the average, have chosen low-paying jobs in which workers enjoy the freedom of entering and leaving the labor force, which reduces their years of experience relative
to men. Other people say the gap can also be explained by the difference in educational background.
Much of the gap, however, has not been fully explained. It might be the result of some prejudice (偏见) against women. It is this part that has produced calls for government action. What would happen if the government did intervene to
increase the wages paid to women? One possibility is that incomes for women as a group might actually decline (下降). An increase in wage decreases the quantity of labor imput demanded, resulting in decreased employment as the rate of hiring new
workers declines. The result will be a surplus 过剩) of labor. Those who can find jobs might be better off while those who had jobs
might find themselves out of work.
