Inconvenient Wage Disparity

November 4, 2008 by Stephen J. Haessler

Here’s an interesting paragraph from Thomas Sowell’s excellent book called Applied Economics: Thinking Beyond Stage One. It is contained in the chapter on the economics of discrimination. One of the points of this chapter is the importance of comparing like to like in statistical analysis.

“[A] study of black and white faculty members in the United States found that those who were comparable on some variables were nonetheless very different on other variables. Even black professors with Ph.D.’s usually received those Ph.D.’s at a later age, from institutions with lower rankings, in their respective fields, and these professors had published fewer articles. When such variables as published articles, the ranking of institutions from which Ph.D.’s were earned, and years of academic experience were all held constant, black professors with Ph.D.’s earned more (emphasis in the original) than white professors with Ph.D.’s, as far back as 1970 — a year before affirmative action policies were mandated by the federal government.” (p. 183)

The study referred to is identified on p. 235 as Dr. Sowell’s, titled “Affirmative Action in Faculty Hiring.”

    For me, the question behind the post is what inference the writer wants the reader to draw from the information. I get the impression you are suggesting that perceived disparities in the salaries of minority Ph.D’s stem from the generally inferior quality of minority Ph.D’s credentials as opposed to race. However, the question I find equally intriguing is why minority Ph.D’s generally underperform in terms of credentials when compared with other faculty members. I’d look out for an underlying argument in this post that appears to venture into the Bell Curve theory. Either this is just the natural order of things and we should be resigned to the achievement gap or this is a symptom of a flaw in our education system that is systematically punishing minority students for being a minority. If the former, then wage disparities are not problematic and possibly helpful. If the latter, then we should all take the problem of wage disparities very seriously.
