Unfortunately, what the author is citing (“Equal pay for equal work is fair,” Mailbox, Wednesday) is Web-posted, nonpeer-reviewed advocacy “research.”
What she should be citing is peer-reviewed research published in the highest-level journals in the field. Had she skipped the Web and read America’s most prestigious peer-reviewed economics journal, she would have found an article by economist June O’Neill, the former director of the Congressional Budget Office.
The article is titled, “The gender gap in wages, circa 2000,” and is published in the May 2003 issue of the American Economic Review.
By factoring in some of the many work-related differences between men and women such as hours worked per week, danger and travel requirements of the job, years of education, years in the field, and many other characteristics, Mrs. O’Neill found the purported pay gap virtually vanished.
Sound public policy requires sound science and not self-serving, Web-posted, advocacy “research.”
