Tim Smeeding gestured at the white board in his University of Wisconsin office and told me the indecipherable scrawling related to a model for measuring poverty. I?ll have to take his word. Like many professors on the Madison campus, Smeeding is a star. He?s been director of UW-Madison?s Institute for Research on Poverty and is a national poverty expert, a prolific author and someone regularly quoted in the national media.
