Studies on Social Mobility

To All:

The Wall Street Journal of 17 August dusted off and referred to two studies attempting to show social mobility is the rule, rather than the exception, in the United States. One study, a "U.S. Treasury" study of 14,351 households, which found in a nine-year period between 1979 to 1988 86% of those in the lowest income quintile "moved up, two-thirds to the middle-class and almost 15% into 'that piggy' top quintile." The second study quoted was a University of Michigan Panel Survey on Income Dynamics, which tracked over 3,000 people from 1975 to 1991. The study purportedly found that after 17 years only 5% of the "bottom dwellers" were still on the bottom, concluding that 95%, therefore, moved up, "29% were setting plumply in the top fifth."

I believe I have heard of the "U.S. Treasury" study and the rather poor methodology used by those conducting it. I seem to remember it having been solidly discredited by those who have looked into the methodology. (Somehow, I seem to recall it was conducted at the bequest of a Republican-led committee within Congress, but I am not sure). I have not heard of the University of Michigan Panel Survey.

Has anyone heard of either of these studies and where one might get a copies? I am particularly interested in the methodologies, findings, and sampling; as well as, reactions. I would like to use these as examples in my Intro and social stratification classes this fall.
